Abstract
BACKGROUND Hemotropic Mycoplasma species (hemoplasmas) cause hemolytic anemia in cats worldwide and are recognized as emerging zoonotic pathogens. There is no comprehensive study on the prevalence and species diversity of hemoplasmas in domestic cat populations in different regions in Iran. Thus, the aims of the present study were to provide data on the prevalence and molecular characterization of hemotropic Mycoplasma species in apparently healthy cats from six Iranian provinces with different climates. In addition, potential risk factors associated with hemoplasmosis in cats were assessed. RESULTS Mycoplasma spp. DNA was detected in the blood of 56 / 361 cats (15.5%) using genus-specific PCR. Further examinations with species-specific PCR and Sanger sequencing showed that 38 cats (10.5%) tested positive for Candidatus Mycoplasma haemominutum (CMhm), 8 cats (2.2%) tested positive for Mycoplasma haemofelis (Mhf), and 2 cats (0.6%) tested positive for Candidatus Mycoplasma turicensis (CMt). Co-infection with CMhm, and Mhf was observed in 7 cats (1.9%). One cat (0.3%) showed mixed infection with CMhm, Mhf, and CMt. There were statistically significant relationships between Mycoplasma positivity and being female, living in shelter (cattery), and being over 3 years old (P < 0.05). No significant association was observed for the cat breed and sampling localities. CONCLUSIONS Current study findings revealed that hemoplasma infections are common among Iran cat populations. Considering the impact of such emerging zoonotic pathogens on the One Health, routine screenings, increasing public awareness, effective control, and prophylactic strategies for minimizing infection in cats and subsequently in human are strongly recommended.

Abstract
BACKGROUND Hemotropic mycoplasmas, hemoplasmas, are epi-erythrocytic parasitic bacteria that can be transmitted through blood transfusion. OBJECTIVES To study the prevalence of hemoplasma infection of potential feline blood donors and investigate the association between Hemoplasma spp. quantitative polymerase chain reaction (qPCR) positivity in blood units and selected variables. ANIMALS Seven thousand five hundred seventy-three blood units from 4121 privately-owned potential donor cats. METHODS Retrospective observational cross-sectional study. The Banco Sangue Animal (BSA)-Animal Blood Bank medical database was reviewed for all feline donations performed in 2022 in Portugal, Spain, and Belgium. Baseline characteristics and results of blood-borne pathogens screening tests were extracted from the medical records. RESULTS Two hundred twelve of 4034 Portuguese donor cats and 2 of 70 Spanish donor cats tested positive for Hemoplasma spp. qPCR in 2022 leading to an overall estimated prevalence of 5.2% (95% CI: 4.5%-5.9%) in potential blood donors. Using multivariable generalized estimation equation models, Hemoplasma spp. qPCR was more often positive among blood units issued from male cats (OR = 1.9, 95% CI: 1.4-2.6, P < .0001), units positive for FeLV (OR = 2.8, 95% CI: 1.4-5.6, P = .0023), and units collected in winter months (OR = 2.5, 95% CI: 1.7-3.6, P < .0001). CONCLUSIONS AND CLINICAL IMPORTANCE This study underscores the importance of Hemoplasma spp. and other relevant blood-borne pathogens screening at every donation. Implementing stringent screening protocols is crucial to mitigate the risk of hemoplasma transmission via blood transfusions, thereby safeguarding the health and welfare of cats receiving transfusions.

A case of mistaken identity: a systematic review, meta-analysis, and reinvestigation of hemotropic Mycoplasma spp. infection in Ctenocephalides felis (cat flea). Parasit Vectors 2024; 17:209. [PMID: 38720359 PMCID: PMC11078739 DOI: 10.1186/s13071-024-06292-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 04/21/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Feline-associated hemotropic Mycoplasma (hemoplasmas) are believed to be transmitted by two primary mechanisms: (1) direct transmission via fighting and (2) vector-borne transmission by the cat flea (Ctenocephalides felis). While the efficiency of transmission by C. felis appears low, most manuscripts focus on the prevalence of hemoplasmas in wild-caught fleas and report either a very low (< 3%) or a high (> 26%) prevalence. Therefore, we aimed to assess the influence of sample processing and PCR methods on C. felis hemoplasma infection prevalence. METHODS A systemic review of PubMed articles identified 13 manuscripts (1,531 fleas/flea pools) that met the inclusion criteria (performed PCR for >1 hemoplasma on C. felis collected from cats). Risk of bias was assessed utilizing the ROBINS-E tool. Meta-analysis performed in R of these manuscripts found that not washing samples and a common set of 16S rRNA primers first published in Jensen et al. 2001 were associated with increased hemoplasma prevalence. To evaluate the influence of washing on newly collected fleas, we assessed the hemoplasma status of 20 pools of 5 C. felis each, half of which were washed and half not washed. RESULTS Flea washing did not influence the detection of hemoplasma but instead amplified Spiroplasma. To assess non-specific amplification with the Jensen et al. 2001 primers, 67 C. felis samples (34% previously reported hemoplasma infected) were subject to PCR and sequencing. By this method, hemoplasma was detected in only 3% of samples. In the remaining "hemoplasma infected" fleas, PCR amplified Spiroplasma or other bacteria. CONCLUSIONS Therefore, we concluded that hemoplasma infection in C. felis is rare, and future flea prevalence studies should sequence all positive amplicons to validate PCR specificity. Further investigation of alternative methods of feline-associated hemoplasma transmission and the ability of C. felis to maintain hemoplasma infection is necessary.

Abstract
Background and Aim Feline immunodeficiency virus (FIV) is a retroviral pathogen globally responsible for immunodeficiency disease in cats. However, the current diagnosis based on antibody detection has limitations and can also produce false-positive results. This study aimed to develop a one-pot loop-mediated isothermal amplification (LAMP) process integrated with neutral red (NR-LAMP) assay for detection of FIV proviral DNA. Materials and Methods We developed a one-pot, gag gene-based NR-LAMP for convenient, rapid, specific, and sensitive colorimetric inspection of FIV proviral DNA. Results The developed NR-LAMP was capable of amplifying at an optimum temperature of 65°C for 40 min. No cross-amplification was detected between FIV and other feline viruses tested, indicating the high specificity (98.44%) of the novel FIV-LAMP primer. Our NR-LAMP assay has a detection limit of 4.2 × 101 copies/μL. A total of 80 clinical samples with a background of FIV infection were collected and tested using the proposed method. The NR-LAMP assay showed a high sensitivity of 100% compared to conventional polymerase chain reaction assay. Conclusion These results support the suitability of NR-LAMP as a potential future alternative clinical molecular approach for further use in the diagnosis of FIV-infected cats.

Abstract
Feline panleukopenia (FPL) is a highly contagious cat disease and is endemic in Bangladesh. The study aims to describe the epidemiology and molecular characterization of the Feline panleukopenia virus from the suspected domestic cats in selected Bangladesh regions. Randomly, 161 rectal swabs were collected from the pet hospitals between July 2021 and December 2022. A structured questionnaire was administered through face-to-face interviews with cat owners in order to collect data on potential risk factors for FPL, such as age, sex, sharing litter boxes and every day utensils in multicat households, vaccination history, hospital visits for other diseases, and season. The rectal swabs were tested by PCR targeting the VP2 capsid protein gene, and six PCR-positive samples were further sequenced for molecular characterizations. The risk factors for FPLV were identified using multivariable logistic regression analysis. The overall prevalence of FPL among suspects was 22.9%. The mortality and case fatality were 10.6%, and 45.9%, respectively. However, mortality in kittens was significantly higher (16.4%) than younger cats. The odds of FPL were 8.83 times (95% CI: 3.14-24.85) higher among unvaccinated cats than vaccinated cats. The winter season had almost six times (95% CI: 1.38-24.40) higher odds of FPL than rainy season. In a multicat house, the odds of FPL was about five times (95% CI: 1.93-13.45) higher for cats that shared a litter box and food utensils compared to those that did not engage in such sharing. Visiting hospitals for other reasons nearly triples the odds of FPL (OR: 2.80, 95% CI: 1.04-7.54) compared to cats that do not visit hospitals. Analysis of partial sequence of the VP2 gene revealed genetic variations among the isolates from different regions. Among these isolates, four were identical to FPLV isolates from South Korea and China, while one showed complete homology with FPLV isolates from Thailand. In contrast, the remaining one was 100% identical to Carnivore protoparvovirus-1 isolated from a feline sample in Italy. Our isolates were classified into three distinct clades alongside Feline panleukopenia virus and Carnivore protoparvovirus-1. One in every three suspected cats was infected with Feline panleukopenia. Regular vaccination of the cats, especially those that share common litter box and food utensils and visit hospitals for other purposes, will help reduce the prevalence of FPL in Bangladesh. Besides, it is worth emphasizing the existence of genetic diversity among the circulating Feline panleukopenia viruses in Bangladesh.

Abstract
Bacterial, protozoal, and viral vector-borne pathogens (VBPs) can cause infections in cats. There is little information on feline VBP prevalence in Germany. Stray cats are frequently exposed to vectors but receive no veterinary care. The aim of this study was to determine the prevalence of selected VBPs in stray cats. EDTA blood and serum samples were taken from apparently healthy stray cats during a spay/neuter campaign in the federal state of Thuringia. Overall, 11/50 (22%) and 32/50 (64%) cats tested positive for at least one VBP by direct and indirect detection methods, respectively. PCR testing of EDTA blood detected hemotropic Mycoplasma spp. in 12% of cats, Hepatozoon spp. in 10%, and Anaplasma phagocytophilum in 4%. PCR testing for Rickettsia spp. and piroplasms was negative. IFAT on serum samples showed 46% of cats had detectable antibodies for Bartonella spp., 30% for Rickettsia spp., and 16% for A. phagocytophilum. The cats were additionally tested for feline coronavirus, FIV, and FeLV to identify potential risk factors for pathogen contact and/or infections. No correlation between FIV and FeLV status and VBP positivity was detected. Anaplasma phagocytophilum, Rickettsia spp., and Bartonella spp. have zoonotic potential, and surveillance is recommended in the context of the One Health approach.

Abstract
Background and Aim Feline infectious peritonitis (FIP) is an infectious, immune-mediated, and fatal disease in cats caused by a mutant feline coronavirus (FCoV) infection. Feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) are two common retroviruses that play a role in reducing feline immune function with opportunistic retrovirus infection being a predisposing factor for the development of FIP. This study aimed to evaluate the clinicopathological parameters of FIP in cats with and without retrovirus coinfection. Materials and Methods In total, 62 cats presenting with pleural and/or peritoneal effusion at the Kasetsart University Veterinary Teaching Hospital, Bangkok, Thailand, were selected for the study. Effusion samples were collected and a reverse transcriptase-polymerase chain reaction (RT-PCR) assay was performed on all samples using the 3' untranslated region primer. All FCoV-positive cats were tested for retrovirus infection using a commercial kit (Witness FeLV-FIV [Zoetis]; United States). Clinical signs, hematological, and biochemical parameters of these cats were investigated and grouped. Results Of the 62 cats with pleural and/or peritoneal effusion, FCoV was detected in 32, of which 21 were highly suspicious for FIP. The cats suspected of FIP were divided into three subgroups following viral detection. A total of 14 had only FCoV infection (Group A), four had FCoV and FeLV infection (Group B), and three had FCoV, FeLV, and FIV infection (Group C). Of the rest, 11 had definitive diagnoses, which included three being FCoV and FeLV-positive (Group D), and eight were retrovirus-negative (Group E). Mild anemia and lymphopenia were found in cats infected with these three viruses. An albumin-to-globulin ratio lower than 0.5 was found in FIP cats with only FCoV infection. Conclusion Typically, cats with clinical effusion and FIP, with and without retrovirus coinfection, had similar hematological findings. Clinical signs, blood parameters, fluid analysis with cytological assessment, and RT-PCR assays could identify better criteria to diagnose FIP with and without retrovirus coinfection.

Abstract
A cross-sectional study was conducted on 274 cats in Southern Brazil to estimate the prevalence of Mycoplasma haemofelis PCR, associated factors, and its correlation with ELISA for FeLV and FIV. The apparent prevalence of M. haemofelis was 6.6% (18/274) (95% CI: 3.6-9.5%), of which 33.3% (6/18) had co-infection with FeLV, 5.6% (1/18) with FIV, and 5.6% (1/18) with both. Male cats were more likely to be positive for M. haemofelis [OR: 7.07 (1.97-25.34)]. Only three M. haemofelis-positive cats showed related clinical changes, such as mucosal pallor. A statistically significant difference was observed between M. haemofelis-positive cats and the negative control group for age, hemoglobin concentration, packed cell volume, and rod neutrophil counts. Mycoplasma haemofelis is prevalent in southern Brazil, with a higher risk in male cats. Most cats could be classified as asymptomatic carriers since they were healthy.

Abstract
This retrospective study aimed to evaluate the clinicopathological changes in a population of cats tested for feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV), in an Italian Veterinary University Hospital, in the period between January 2002 and May 2016. During the period of 14 years, 1834 cats were tested, and of these 241/1834 (13.1%) were positive for FIV antibodies and 92/1834 (5%) cats were positive for FeLV antigen. These data confirm the presence of a high prevalence of these viruses on Italian territory. To the authors’ knowledge, this study describes findings that have never been evaluated before, such as iron status in retrovirus-infected cats and urinalysis in FeLV-positive cats. In this study, FIV-positive cats were more likely to have higher serum protein concentration and lower albumin-globulin ratio than other groups of cats. Lower urine specific gravity and higher urine protein to creatinine ratio were also detected for FIV-positive cats when compared with negative and healthy cats. FeLV-positive cats were more likely to have cytopenia, decreased haemoglobin, haematocrit and RBC compared with other groups of cats. The data obtained underline the importance of considering retroviral infections in the presence of a broad spectrum of risk factors and laboratory anomalies.

Abstract
Background and Aim: Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses associated with chronic and neoplastic diseases in domestic and non-domestic cats. There has been increasing interest in the clinical importance of feline retroviruses in Thailand and the identification of associated risk factors in domestic cats. To prevent the spread of retroviral diseases and improve the management of retrovirus-infected cats, risk factors and associated clinical laboratory data must be clearly understood. This study aimed to identify the influence of household, lifestyle, health status, sterilization, clinical presentations, and laboratory findings on FIV- and FeLV-infected cats in Bangkok, Thailand.
Materials and Methods: A total of 480 cats were evaluated for FeLV p27 antigen and FIV antibodies using Witness FeLV-FIV Rapid Test and SNAP FIV/FeLV Combo Test at a veterinary hospital service.
Results: Of the 480 cats tested, 113 were positivefor virus infection, including 60 for FeLV (12.5%), 40 for FIV (8.3%), and 13 for both FeLV and FIV (2.7%). The findings revealed that the risk factors for cats infected with FeLV, FIV, or both FeLV and FIV were significantly different compared with those for non-infected cats (p < 0.05). Multivariate analysis showed that multi-cat ownership is a risk factor for the high prevalence of feline retrovirus infection, as multi-cat households exhibited a higher prevalence of infection than single-cat households. Anemic and sick cats were also at a greater risk of testing positive for specific retrovirus infections. FeLV-infected cats had a higher risk of anemia and low erythrocyte and thrombocyte counts (p ≤ 0.0001), whereas FIV-infected cats were more likely to have anemia and leukocytopenia than controls.
Conclusion: Knowledge of the risk factors for retroviral diseases and associated clinical and laboratory findings can be used to develop strategies to reduce FIV and FeLV infections in cats.

Abstract
Feline haemoplasma infection studies are lacking in Russia. This retrospective study was conducted to estimate the prevalence of feline haemoplasmas in domestic cats in the Moscow region, Russia. A risk of haemoplasma coinfection with feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) was also determined. qPCR analysis for feline haemoplasmas was performed on EDTA blood samples from 753 cats from the Moscow region, Russia. Subsets of these samples were tested also for FIV and FeLV by qPCR. Of the 753 blood samples, 104 (13.8 %) were positive for one of the Mycoplasma species. The prevalence of 'Candidatus Mycoplasma haemominutum' (CMhm), Mycoplasma haemofelis (Mhf), and 'Candidatus Mycoplasma turicensis' (CMt) was 7.6 %, 5.5 %, and 0.7 %, respectively. One sample (0.1 %) was simultaneously infected with two haemoplasmas, namely, Mhf and CMt. Haemoplasma positive cats were more likely to be infected with FIV than haemoplasma negative (17.6 % vs 6.7 %), but these differences were not statistically significant. The prevalence of FeLV was comparable among haemoplasma positive and negative cats (23.5 % vs 25.7 %) All three known species of feline haemoplasma were detected, confirming their presence in Russia. The overall and species-specific rates of haemoplasma infections in Russian cats are generally similar to the rates in the countries of central Europe. This report documents for the first time the prevalence of feline hemotropic mycoplasmas in domestic cats not only in Russia but also in eastern Europe.

Abstract
Sporotrichosis is a subcutaneous infection caused by fungi from the genus Sporothrix. It is transmitted by inoculation of infective particles found in plant-contaminated material or diseased animals, characterizing the classic sapronotic and emerging zoonotic transmission, respectively. Since 1998, southeastern Brazil has experienced a zoonotic sporotrichosis epidemic caused by S. brasiliensis, centred in the state of Rio de Janeiro. Our observation of feline sporotrichosis cases in Brasília (Midwestern Brazil), around 900 km away from Rio de Janeiro, led us to question whether the epidemic caused by S. brasiliensis has spread from the epicentre in Rio de Janeiro, emerged independently in the two locations, or if the disease has been present and unrecognized in Midwestern Brazil. A retrospective analysis of 91 human and 4 animal cases from Brasília, ranging from 1993 to 2018, suggests the occurrence of both sapronotic and zoonotic transmission. Molecular typing of the calmodulin locus identified S. schenckii as the agent in two animals and all seven human patients from which we were able to recover clinical isolates. In two other animals, the disease was caused by S. brasiliensis. Whole-genome sequence typing of seven Sporothrix spp. strains from Brasília and Rio de Janeiro suggests that S. brasiliensis isolates from Brasília are genetically distinct from those obtained at the epicentre of the outbreak in Rio de Janeiro, both in phylogenomic and population genomic analyses. The two S. brasiliensis populations seem to have separated between 2.2 and 3.1 million years ago, indicating independent outbreaks or that the zoonotic S. brasiliensis outbreak might have started earlier and be more widespread in South America than previously recognized.

Abstract
This study aimed to determine the prevalence, factors associated, laboratory findings (with and without coinfection by retroviruses) among naturally infected cats by hemoplasmas in northeastern Brazil. For convenience, 200 domesticated and healthy cats were selected. Blood samples were taken to perform complete blood counts, serum biochemical, immunochromatography tests and nPCR for FIV and FeLV, and PCR for hemoplasma recognition. An interview was conducted to determine the factors associated with hemoplasmas. A total of 71/200 (35.5%) cats were positive for at least one hemoplasma species. Isolated infections were observed in 12,5% for 'Candidatus Mycoplasma haemominutum', 12% for Mycoplasma haemofelis and 3% for 'Candidatus Mycoplasma turicensis'. Regarding copositivity, 2% of the animals were positive for M. haemofelis and 'Candidatus Mycoplasma haemominutum', 1.5% for M. haemofelis and 'Candidatus Mycoplasma turicensis', and 4.5% for ' Candidatus Mycoplasma haemominutum' and 'Candidatus Mycoplasma turicensis'. No clinical and laboratory changes were observed in the animals that were concomitantly positive for retroviruses and hemoplasmas. Periurban region cats were more likely to be infected by M. haemofelis, while contact with other cats and infection by ' Candidatus Mycoplasma turicensis' were associated with 'Candidatus Mycoplasma haemominutum'. This study indicates that infection by hemoplasmas is a common find in cats from northeastern Brazil.

Abstract
Objectives The objectives of this study were to estimate the prevalence of feline haemoplasma infections in Northern Serbia, identify potential risk factors and perform molecular subtyping of feline immunodeficiency virus (FIV). Methods PCR analysis for feline haemoplasmas was performed on surplus EDTA blood samples from 373 cats from the Belgrade region, Serbia. An ELISA was used to determine the prevalence of feline leukaemia virus (FeLV) and FIV; PCR was performed on a subpopulation of these cats. FIV subtyping was performed using PCR. Results Within this population, 64/373 cats (17.2%) were infected with one or more haemoplasma species. Mycoplasma haemofelis was detected in 20/373 cats (5.4%), ‘Candidatus Mycoplasma haemominutum’ in 47/373 cats (12.6%) and ‘Candidatus Mycoplasma turicensis’ in 23/373 cats (6.2%). Coinfections were observed in 21/373 cats (5.6%). Based on ELISA serological retroviral testing, 4/310 cats (1.3%) were infected with FeLV, whereas 78/331 (23.6%) were infected with FIV. Multivariable analysis identified significant associations between haemoplasma infection and anaemia (anaemic/non-anaemic, odds ratio [OR] 2.7, 95% confidence interval [CI] 1.04–7.1; P = 0.041]), male gender (male/female, OR 4.5, 95% CI 2.22–9.03; P <0.0005), outdoor access (yes/no, OR 5.2, 95% CI 2.28–11.92; P <0.0005), non-pedigree breed (non-pedigree/pedigree, OR 5.5, 95% CI 1.24–24.84; P = 0.025) and FIV seropositive status (positive/negative, OR 2.4, 95% CI 1.21–4.83; P = 0.012). PCR analysis of the FIV ELISA-positive samples revealed clade D as being the most prevalent. Conclusions and relevance All three known species of feline haemoplasma were detected, confirming their presence in Serbia; ‘Candidatus Mycoplasma haemominutum’ was the most prevalent. We found a high prevalence of FIV-infected cats and FIV clade D was most prevalent.

Abstract
Background Visceral leishmaniasis (VL) has been increasingly recognized in cats living in areas endemic for the disease. Co-infection with Leishmania infantum and other infectious agents is well established in dogs. However, for cats, data on co-infections with L. infantum and other infectious agents are still sparse. The aim of this study was to identify the prevalence of vector-borne pathogens, Mycoplasma spp., feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) in cats from an area endemic for VL in southeastern Brazil. Results Of the 90 cats, eight (8.9%) were infected with Mycoplasma spp., five (5.5%) were FIV- positive and one (1.1%) was FeLV-positive. Co-infection with L. infantum and at least one other infectious agent was found in 9/50 (18.0%; CI: 8.6–31.4%) cats. In Group 1 (cats infected naturally by L. infantum), 4/50 (8.0%) cats were positive for FIV, 4/50 (8%) for Mycoplasma spp. and 1/50 (2.0%) was co-infected with FeLV and Mycoplasma spp. In Group 2 (cats non-infected with L. infantum), 2/40 (5.0%) cats were infected with Mycoplasma spp. and 1/40 (2.5%) was co-infected with FIV and Mycoplasma spp. All cats were negative for Ehrlichia spp., Babesia spp. and Anaplasma platys. Conclusion A low prevalence of co-infection in Leishmania-infected and non-infected cats was found. Co-infections with Leishmania and vector-borne diseases in cats are not common in this area endemic for VL in Brazil.

Abstract
OVERVIEW Haemoplasmas are haemotropic bacteria that can induce anaemia in a wide range of mammalian species. Infection in cats: Mycoplasma haemofelis is the most pathogenic of the three main feline haemoplasma species known to infect cats. ' Candidatus Mycoplasma haemominutum' and ' Candidatus Mycoplasma turicensis' are less pathogenic but can result in disease in immunocompromised cats. Male, non-pedigree cats with outdoor access are more likely to be haemoplasma infected, and ' Candidatus M haemominutum' is more common in older cats. All three haemoplasma species can be carried asymptomatically. Transmission: The natural mode of transmission of haemoplasma infection is not known, but aggressive interactions and vectors are possibilities. Transmission by blood transfusion can occur and all blood donors should be screened for haemoplasma infection. DIAGNOSIS AND TREATMENT PCR assays are the preferred diagnostic method for haemoplasma infections. Treatment with doxycycline for 2-4 weeks is usually effective for M haemofelis-associated clinical disease (but this may not clear infection). Little information is currently available on the antibiotic responsiveness of ' Candidatus M haemominutum' and ' Candidatus M turicensis'.

Abstract
First description of feline hemoplasma and immunodeficiency virus in endangered Persian Leopard species in Iran, Middle East. No zoo-kept wild felids were infected. Close sequence identity with hemoplasma isolates from domestic and wild felids in Iran and other geographical origins. Both ‘Ca. M. haemominutum’ infected leopards were old and male and were not born nor residing in zoos.
Three feline hemoplasma species exist in felids: Mycoplasma haemofelis, ‘Candidatus Mycoplasma haemominutum’, and ‘Candidatus Mycoplasma turicensis’. The aims of the study were to determine the presence of, and molecularly characterize, any hemoplasmas in wild felids, including the endangered Persian leopard in Iran, the Middle East. Blood samples were collected from 19 wild felids, including three Persian leopards. Using species-specific hemoplasma PCRs and ELISA serological testing for feline leukaemia virus and feline immunodeficiency virus (FIV), two Persian leopards were found to be infected with ‘Ca. M. haemominutum’ and were seropositive for FIV. Partial 16S rRNA gene sequences were generated for these ‘Ca. M. haemominutum’ species and subsequent phylogenetic analysis revealed 97.70% to 99.45% sequence identity with those found in domestic cats from Iran and other countries. This study confirms the presence of ‘Ca. M. haemominutum’ and concurrent FIV antibody in wild felids in Iran. This represents the first report of hemoplasma in wild felids in the Middle East as well as the first report of infection in Persian leopards.

Abstract
This study aimed to detect Mycoplasma spp. in naturally infected cats from Rio de Janeiro and to evaluate hematological abnormalities and factors associated with this infection. Out of the 197 cats sampled, 11.2% presented structures compatible with hemoplasma organisms on blood smears. In contrast, 22.8% were positive for Mycoplasma spp. by means of 16S rRNA gene real-time polymerase chain reaction, which reflects the weak concordance between techniques. The infection rates, by means of 16S rRNA gene conventional polymerase chain reaction, was 4.6%, 4.6% and 11.7% for Mycoplasma haemofelis (Mhf), 'Candidatus Mycoplasma turicensis' (CMt) and 'Candidatus Mycoplasma haemominutum' (CMhm), respectively. Mhf and CMhm infections are more frequent in the summer (p>0.05). Presence of anemia (p < 0.02), lymphocytosis (p < 0.03), thrombocytopenia (p < 0.04) and activated monocytes (p < 0.04) was associated with Mhf infection. No hematological abnormality was associated with CMt or CMhm infection. Male cats were more prone to be infected by Mhf or CMhm (p < 0.01). Adult cats had more chance to be infected by CMhm. Three hemoplasma species occur in the metropolitan region of Rio de Janeiro and Mhf seems to be the most pathogenic of them. Anemia is the most important hematological abnormality.

Abstract
Abstract Hemotropic mycoplasmas in dogs, such as Mycoplasma haemocanis, have been described worldwide. Recently, these pathogens have been reported to be causative agent of zoonosis. It is known that its transmission may occur through the action of blood-sucking arthropods (e.g. ticks or fleas), through blood transfusion, contaminated fomites and/or transplacentally. In Brazil, M. haemocanis is present in practically all regions and the tick Rhipicephalus sanguineus sensu lato is suspected the main vector. In the municipality of Campo Grande, state of Mato Grosso do Sul, there is little information about infection of dogs by M. haemocanis, or on the main epidemiological features associated with it. Thus, the aim of the present study was to determine the occurrence of M. haemocanis among dogs infested by ticks and to assess possible associations with some epidemiological factors. The polymerase chain reaction (PCR) and DNA sequencing were used to analyze dog blood samples (n = 94). DNA from M. haemocanis was detected in four samples. No significant associations were observed with any epidemiological parameter analyzed here. However, the results from this study confirm that this pathogen is circulating in this region and should be considered in the differential diagnosis of diseases among anemic dogs.

High prevalence of Felis catus gammaherpesvirus 1 infection in haemoplasma-infected cats supports co-transmission. Vet J 2016; 214:117-21. [PMID: 27387737 DOI: 10.1016/j.tvjl.2016.06.001] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2016] [Revised: 05/24/2016] [Accepted: 06/03/2016] [Indexed: 01/23/2023]
Abstract
Felis catus gammaherpesvirus 1 (FcaGHV1), a potential feline pathogen, has been identified in domestic cats from USA, Asia-Pacific and Central Europe. Transmission of FcaGHV1 during territorial encounters, a route not typical for gammaherpesviruses, is suggested by risk factor analyses from some regions. The aim of this study was to investigate the relationship between FcaGHV1 detection and risk factors, including haemoplasma co-infections, among UK cats to better understand transmission and global distribution of FcaGHV1. FcaGHV1 DNA was detected in blood samples from UK cats (11.56%; 95% confidence interval [CI], 7.47-16.84; n = 199). Logistic regression analyses showed that entire male cats were more likely to be FcaGHV1 positive than neutered male cats (odds ratio, 3.60; 95% CI, 1.22-10.46). Samples positive for DNA from any of three haemoplasma species had 19 times greater odds for testing positive for FcaGHV1 than haemoplasma negative cats in multivariable analyses after adjusting for age, sex and neuter status. Domestic cats in the UK can be infected with FcaGHV1, confirming that this virus is globally endemic. The identification of neuter status as a risk factor for FcaGHV1 detection provides further evidence to support transmission of this virus during territorial encounters and co-transmission with haemoplasmas is suggested.

Abstract
Mycoplasma haemofelis (Mhf), ‘Candidatus Mycoplasma haemominutum’ (CMhm) and ‘Candidatus Mycoplasma turicensis’ (CMt) are agents of feline haemoplasmosis and can induce anaemia in cats. This study aimed to determine the prevalence and phylogeny of haemoplasma species in cats from Brazil's capital and surrounding areas, and whether correlation with haematological abnormalities existed. Feline haemoplasmas were found in 13.8% of 432 cats. CMhm was the most prevalent species (in 13.8% of cats), followed by Mhf (11.1%) and CMt (4.4%). Over 80% of haemoplasma-infected cats harboured two or more feline haemoplasma species: 7.1% of cats were co-infected with Mhf/CMhm, 0.4% with CMhm/CMt and 3.9% with Mhf/CMhm/CMt. Male gender was significantly associated with haemoplasma infections. No association was found between qPCR haemoplasma status and haematological variables, however CMhm relative copy numbers were correlated with red blood cell (RBC) numbers and packed cell volume (PCV). Haemoplasma 16S rRNA gene sequences (> 1 Kb) were derived from co-infected cats using novel haemoplasma species-specific primers. This allowed 16S rRNA gene sequences to be obtained despite the high level of co-infection, which precluded the use of universal 16S rRNA gene primers. Within each species, the Mhf, CMhm and CMt sequences showed > 99.8%, > 98.5% and > 98.8% identity, respectively. The Mhf, CMhm and CMt sequences showed > 99.2%, > 98.4% and > 97.8% identity, respectively, with GenBank sequences. Phylogenetic analysis showed all Mhf sequences to reside in a single clade, whereas the CMhm and CMt sequences each grouped into three distinct subclades. These phylogeny findings suggest the existence of different CMhm and CMt strains. Over 80% of haemoplasma-infected cats had more than one haemoplasma species. The use of species-specific primers allowed derivation of 16S rDNA sequences from co-infected cats. Male gender was significantly associated with haemoplasma infection. Phylogenetic analysis showed subclade formation within two of the haemoplasma species sequences.

Abstract
Three hemoplasma species are recognized in domestic cats: Mycoplasma haemofelis, ‘Candidatus Mycoplasma haemominutum’ and ‘Candidatus Mycoplasma turicensis’. We report the prevalence and hematological abnormalities of hemoplasma infection in 369 domestic cats from three different populations (blood donors, hospitalized cats and shelter cats) from Southern Brazil. Complete blood counts were performed at the time of blood collection, and DNA was extracted and tested by conventional PCR for each hemoplasma species. A total of 79 samples (21.40%) were positive for at least one species. The most prevalent hemoplasma was ‘Candidatus Mycoplasma haemominutum’, with 50/369 (13.55%) positive cats, followed by ‘Candidatus Mycoplasma turicensis’, 10/369 (2.71%), and Mycoplasma haemofelis, 8/369 (2.16%). Mycoplasma haemofelis and ‘Candidatus Mycoplasma haemominutum’ coinfection was observed in 4/369 (1.08%), whereas ‘Candidatus Mycoplasma haemominutum’ and ‘Candidatus Mycoplasma turicensis’ in 5/369 (1.35%). Three cats (0.81%) were infected with all three hemoplasmas. There was no association between infection and the different populations. Anemia was associated with Mycoplasma haemofelis and ‘Candidatus Mycoplasma haemominutum’, but not with ‘Candidatus Mycoplasma turicensis’. Male cats and cats with outdoor access were more likely to be infected. Although ‘Candidatus Mycoplasma haemominutum’ is believed to cause minimal or no hematological alterations, the infected cats studied herein were more likely to be anemic.

Abstract
Objectives The aim of the present study was to evaluate the prevalence of haemoplasma infection in cats in Portugal and to assess risk factors for infection. Methods Real-time polymerase chain reaction techniques were used to assess 236 urban and rural cats from central and southern Portugal. Results The overall prevalence of haemoplasma in the target population was 27.1% (64/236), with individual species’ prevalences as follows: 17.8% (42/236) ‘ Candidatus Mycoplasma haemominutum’ (CMhm), 14.4% (34/236) Mycoplasma haemofelis (Mhf) and only 5.9% (14/236) ‘ Candidatus Mycoplasma turicensis’ (CMt). Multiple infections were detected in 8.1% (19/236) of the samples, with triple and double infections with Mhf and CMhm being most commonly detected (5.9% [14/236] of cats). Haemoplasma infection was significantly higher in shelter cats ( P = 0.015) than in cats with other lifestyles (eg, free-roaming/house pet/blood donors). Haemoplasma prevalence was also higher in cats with feline immunodeficiency virus infection (FIV; P = 0.011). Although sex was not significantly associated with haemoplasma infection ( P = 0.050), CMt was predominantly found in males ( P = 0.032). Also, the presence of haemoplasma multiple infections was statistically associated with being in a shelter ( P = 0.021), male ( P = 0.057) and with FIV co-infection ( P = 0.004). No evidence of an association between haemoplasma infection and geographical location, age or feline leukaemia virus co-infection was found. Conclusions and relevance The results obtained in our study are consistent with the documented worldwide prevalence of feline haemoplasma infections, suggesting that the three main feline haemoplasma species are common in Portugal.

Abstract
Hemoplasmas are bacteria living in feline red blood cells. Feline hemoplasmosis is frequently associated with old male cats that have access to the streets. This study aimed to detect the presence of hemoplasma speciess in domiciled and free-roaming cats in Campo Grande, state of Mato Grosso do Sul (MS), Brazil, using molecular techniques. Between January 2013 and April 2013, EDTA-whole blood samples were collected from 151 domestic cats (65 free-roaming and 86 domiciled cats). Samples were subjected to PCR assays targeting hemoplasmas 16S rRNA, followed by sequencing, BLAST analysis and phylogenetic analysis. Results show an occurrence of 36.4% for hemoplasmas. Twenty-three cats (15.2%) were positive for ‘Candidatus Mycoplasma haemominutum’, 17 (11.2%) for M. haemofelis and 15 (9.9%) for ‘Candidatus M. turicensis’, from PCR. Coinfection by two or three hemoplasmas was found in 25 cats (16.6%). No statistically significant difference between genders or between lifestyles was observed for the presence of hemoplasmas among the cats. Results show different hemoplasma species are present in cat population (Campo Grande, MS, Brazil). It is suggested that a differential diagnosis for feline hemoplasmosis should be made when cats show nonspecific clinical signs of disease with systemic manifestation.

Abstract
Hemotrophic mycoplasmas (hemoplasmas), Bartonellasp., Hepatozoon sp. and Cytauxzoon felis are prominent pathogens that circulate between cats and invertebrate hosts. The present study aimed to detect the presence of DNA from hemoplasmas,Bartonella sp., Hepatozoon sp. andCytauxzoon felis, and then confirm it by means of sequencing, in blood samples from cats in Cuiabá, MT, Brazil. From February 2009 to February 2011, blood samples with added EDTA were collected from 163 cats that were being housed in four different animal shelters in the city of Cuiabá, state of Mato Grosso, Brazil and from 15 cats that were admitted to the veterinary hospital of the Federal University of Mato Grosso (UFMT). Out of the 178 cats sampled, 15 (8.4%) were positive for hemoplasmas: four (2.2%) forMycoplasma haemofelis, 12 (6.7%) for ‘Candidatus M. haemominutum’ and one (0.5%) for ‘Candidatus M. turicensis’. One cat (0.5%), a patient that was attended at the veterinary hospital, was coinfected with M. haemofelis, ‘Candidatus M. haemominutum’ and ‘Candidatus M. turicensis’, based on sequencing confirmation. Four cats were positive for Bartonella spp.: three (1.7%) for B. henselae and one (0.5%) for B. clarridgeiae. None of the animals showedCytauxzoon sp. or Hepatozoon sp. DNA in their blood samples. This study showed that cats housed in animal shelters in the city of Cuiabá, state of Mato Grosso, are exposed to hemoplasmas andBartonella species.

Abstract
The haemotropic mycoplasmas (haemoplasmas) are a group of bacteria that can induce anaemia in a wide variety of mammals, including domestic cats and wild felids. Different feline haemoplasma species of varying pathogenicity exist, with the more pathogenic Mycoplasma haemofelis (Mhf) capable of inducing severe haemolytic anaemia, whilst 'Candidatus Mycoplasma haemominutum' (CMhm) and 'Candidatus Mycoplasma turicensis' (CMt) are infrequently associated with clinical disease. Chronic haemoplasma infections are common and cats are frequently infected by two or more haemoplasmas, complicating the clinical picture. The natural route of transmission of haemoplasma infection between cats has not yet been determined; however, experimental transmission has been demonstrated via both oral and parenteral administration of infected blood. To date the haemoplasmas have been unable to be cultured in vitro, and accurate diagnosis is currently reliant on detection of bacterial DNA using PCR assays. Treatment of clinical haemoplasmosis is focussed on supportive care in combination with empirical treatment with antimicrobials (tetracyclines or fluoroquinolones). A significant number of asymptomatic cats are positive for haemoplasma infection. These cats may play a role in the maintenance of haemoplasma infection within a population, and need to be considered when choosing potential blood donors. Use of PCR assays has provided an accurate method of diagnosing haemoplasma infection and quantifying response to therapy, including in non-feline host animals, as presumed zoonotic haemoplasma infections are now being documented. Recent advances in genome sequencing techniques have allowed the whole genome sequences of the feline haemoplasmas Mhf and CMhm to be derived, as well as a number of non-feline haemoplasma species. These data have aided the identification of antigens for use in the development of serological tests, allowed the proteomic study of haemoplasmas and provided clues as to how the haemoplasmas can persist within the host. Future areas of study include investigation of their zoonotic potential, mechanisms of immune system evasion and transmission of these emerging pathogens.

Abstract
Hemotrophic mycoplasmas and Bartonella species are important pathogens that circulate between cats and invertebrate hosts, occasionally causing diseases in humans. Nevertheless, there are few reports on occurrences of these agents in cats in Brazil. The present study aimed to detect the presence of hemoplasma and Bartonella DNA by means of PCR and sequencing. FIV antigens and anti-FeLV antibodies, were studied by using a commercial kit on blood and serum samples, respectively, among 46 cats that were sampled during a spaying/neutering campaign conducted in Jaboticabal, SP. Three (6.5%) cats were positive for hemoplasmas: two (4.3%) for 'Candidatus M. haemominutum' and one (2.2%) for both M. haemofelis and 'Candidatus M. turicensis'. One of the two 'Candidatus M. haemominutum'-infected cats was also positive for FeLV antigens and showed antibodies for FIV. Two cats (4.3%) were positive for B. henselae. One of them was also positive for FeLV antigens. Eight cats (17.4%) were positive for FeLV, and just one (2.2%) showed anti-FIV antibodies. Bartonella species and hemoplasmas associated with infection due to retroviruses can circulate among apparently healthy cats.

Abstract
Hemoplasmas are bacteria that infect erythrocytes, attaching to the red blood cell. There is a need for more reports of hemoplasma infection prevalence and molecular characterization among cats in Brazil since there are only few published reports. The present work aimed to detect and molecularly characterize the presence of hemotrophic mycoplasmas in domestic cats with outdoor access from São Luís, Maranhão, Brazil. Twenty cats (10%) were positive for Candidatus M. haemominutum, five (2.5%) for M. haemofelis, and four (2.%) for M. turicensis based on 16S rRNA gene PCRs. Five cats (2.5%) were co-positive for Candidatus M. haemominutum and M. haemofelis. PCR diagnosis was confirmed by sequencing; and phylogenetic analysis was based on 16S rRNA and rnpb genes.

Abstract
The prevalence and risk factors of 2 bovine hemoplasma species-Mycoplasma wenyonii (Mw) and "Candidatus Mycoplasma haemobos" (CMh)-were examined by direct PCR using whole blood samples collected from 343 cattle in Eastern Hokkaido, Japan. The sensitivity of the direct PCR assay was 10-fold higher than the standard PCR assay, detecting 5 copies of bovine hemoplasma DNA per reaction. An epidemiological survey of sampling location, living conditions, age and bovine leukemia virus antibody was performed to assess infection risk factors. The prevalence rates were 38.5% for Mw and 39.1% for CMh, respectively, with an overall prevalence rate of 64.7% for all bovine hemoplasma infections. Significant differences were found in sampling location, living conditions and age. Compared with pastured cattle, farmed cattle were significantly more susceptible to infection with total hemoplasma species (P<0.001), and were particularly susceptible to CMh (P<0.001). Cattle that were 1-3 years of age were more susceptible to infection with hemoplasma compared with other age groups. Bovine leukemia virus infection status was not significantly associated with hemoplasma infections. Blood examination revealed significantly lower RBC, Hb, and PCV levels, and a higher MCV in infected cattle than in noninfected cattle.

Abstract
'Candidatus Mycoplasma haemominutum' (CMhm) is a hemotropic mycoplasma (aka hemoplasma) of domestic cats and wild felids. In a transmission study, we exposed eight specified pathogen-free cats to blood from Iberian lynxes (Lynx pardinus) infected with CMhm. The cats were coinfected with feline leukemia virus (FeLV) from an Iberian lynx or with a prototype FeLV. The goal of the present study was to quantify the humoral immune response to CMhm and to identify potential target tissues and sequestration sites. Antibodies were measured by a recombinant antigen-based enzyme-linked immunosorbent assay, and blood and tissue loads were quantified using real-time PCR. Seven out of eight cats became CMhm-infected; all of these cats seroconverted between 3 and 13 weeks after inoculation. Antibody levels correlated with the CMhm blood loads. The peak CMhm blood loads were inversely correlated with the incubation period. PCR-positive results were found in all 24 tissues tested but not for all samples. Although all tissues were PCR-positive in one cat euthanized ten weeks after infection, many tissues tested negative in six cats euthanized at week 20 after infection. In several cats, the spleen, lung, liver, heart and aorta contained more copies than expected given the tissue's blood supply, but most tissues contained fewer copies than expected. In conclusion, this is the first study to quantify the humoral immune response and tissue loads in CMhm-FeLV-coinfected cats. The tissue loads appeared to correlate with the duration of infection and with the blood loads, but no evidence of significant CMhm tissue sequestration was found.

Abstract
The rapid emergence of AIDS in humans during the period between 1980 and 2000 has led to extensive efforts to understand more fully similar etiologic agents of chronic and progressive acquired immunodeficiency disease in several mammalian species. Lentiviruses that have gene sequence homology with human immunodeficiency virus (HIV) have been found in different species (including sheep, goats, horses, cattle, cats, and several Old World monkey species). Lentiviruses, comprising a genus of the Retroviridae family, cause persistent infection that can lead to varying degrees of morbidity and mortality depending on the virus and the host species involved. Feline immunodeficiency virus (FIV) causes an immune system disease in domestic cats (Felis catus) involving depletion of the CD4+ population of T lymphocytes, increased susceptibility to opportunistic infections, and sometimes death. Viruses related to domestic cat FIV occur also in a variety of nondomestic felids. This is a brief overview of the current state of knowledge of this large and ancient group of viruses (FIVs) in South America.

Abstract
The prevalence of A, B and AB blood types and of feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) infection was determined in cats in Ireland, in order to determine risk factors for blood taken for transfusion purposes. EDTA blood samples were available from 137 non-pedigree cats and 39 pedigree cats (91 females and 85 males, aged four months to 15.0 years) in the Dublin area of Ireland. Of the 176 EDTA blood samples obtained, 112 (from 92 healthy cats and 20 sick cats) were tested for the presence of both FIV antibodies and FeLV antigens. Blood typing was performed using an immunochromatographic cartridge (CHROM; Alvedia). Testing for FIV and FeLV was performed by ELISA (SNAP FIV/FeLV Combo Test; Idexx Laboratories). Of the 39 pedigree cats, the majority (38 [97.4 per cent]) was type A, and only one (2.6 per cent) was type B. Of the 137 non-pedigree cats, the majority (116 [84.7 per cent]) was type A, 20 (14.6 per cent) were type B, and one (0.7 per cent) was type AB. Of the 92 healthy cats tested, the prevalence of FIV and FeLV positivity was 4.35 and 1.09 per cent, respectively. None of the 20 sick cats tested was FIV-positive; two (10 per cent) of the 20 sick cats were FeLV-positive.

Abstract
PRACTICAL RELEVANCE blood transfusions are a potentially life-saving procedure that are within the reach of most small animal practitioners. Only minimal equipment is required. PATIENT GROUP any cat with clinical signs attributable to a reduced red blood cell mass that is affecting oxygen transport (as a result of reduced packed cell volume or acute blood loss) is a potential candidate for a transfusion. CLINICAL CHALLENGES although the principles of transfusion medicine are not complicated, there can be fatal consequences if certain steps are omitted. DIAGNOSTICS blood typing kits and blood filters are readily available from veterinary wholesalers, laboratories and blood banking services. EVIDENCE BASE over the past three decades, a substantial body of clinical research and reports has built up covering feline blood types and transfusion medicine. This article draws on that research to provide clinical guidance aimed at all veterinarians in feline or small animal practice who either currently practise transfusion medicine or plan to do so.

Abstract
Vector-borne bacterial and rickettsial agents and Toxoplasma gondii, are common organisms in cats. Some are potentially zoonotic or may be transmitted via blood transfusion. The current study investigated the prevalence of these agents in cats from Dublin, Ireland, for which no published data exists. Whole blood (n=116) and sera (n=83) samples were obtained from 121 cats. DNA was extracted from blood and assayed using polymerase chain reaction techniques for Anaplasma species, Bartonella species, Ehrlichia species, Mycoplasma haemofelis, 'Candidatus Mycoplasma haemominutum', 'Candidatus Mycoplasma turicensis' and Rickettsia species. IgG and T gondii IgG and IgM serum antibodies were detected by enzyme-linked immunosorbent assay. DNA consistent with B henselae (3.4%), B clarridgeiae (0.8%), both Bartonella species (0.8%), C M haemominutum (12.9%), or M haemofelis (2.5%) was amplified from 24/116 blood samples (20.6%). Antibodies to T gondii and Bartonella species were detected in 28 (33.7%) and 22 (26.5%) of 83 sera, respectively.
