Mycoplasmas as Host Pantropic and Specific Pathogens: Clinical Implications, Gene Transfer, Virulence Factors, and Future Perspectives. Front Cell Infect Microbiol 2022; 12:855731. [PMID: 35646746 PMCID: PMC9137434 DOI: 10.3389/fcimb.2022.855731] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Accepted: 04/04/2022] [Indexed: 12/28/2022] Open
Abstract
Mycoplasmas as economically important and pantropic pathogens can cause similar clinical diseases in different hosts by eluding host defense and establishing their niches despite their limited metabolic capacities. Besides, enormous undiscovered virulence has a fundamental role in the pathogenesis of pathogenic mycoplasmas. On the other hand, they are host-specific pathogens with some highly pathogenic members that can colonize a vast number of habitats. Reshuffling mycoplasmas genetic information and evolving rapidly is a way to avoid their host's immune system. However, currently, only a few control measures exist against some mycoplasmosis which are far from satisfaction. This review aimed to provide an updated insight into the state of mycoplasmas as pathogens by summarizing and analyzing the comprehensive progress, current challenge, and future perspectives of mycoplasmas. It covers clinical implications of mycoplasmas in humans and domestic and wild animals, virulence-related factors, the process of gene transfer and its crucial prospects, the current application and future perspectives of nanotechnology for diagnosing and curing mycoplasmosis, Mycoplasma vaccination, and protective immunity. Several questions remain unanswered and are recommended to pay close attention to. The findings would be helpful to develop new strategies for basic and applied research on mycoplasmas and facilitate the control of mycoplasmosis for humans and various species of animals.

Abstract
Hemotropic mycoplasmas cause hemolytic anemia in a variety of wild and domestic mammals. Despite growing evidence about their widespread presence and genetic diversity in wildlife, their presence has never been investigated in Chilean artiodactyls. We aimed to describe the presence and diversity of hemoplasmas in pudus (Pudu puda), a small cervid native to Chile. Hemoplasma infection was assessed in blood samples from 43 wild and 33 captive pudus from central and southern Chile by direct sequencing of the 16S rRNA gene. We detected hemoplasmas in 13%, with no statistical differences between wild (19%) and captive animals (6%). A sequence closely related to Mycoplasma ovis was present both in wild (14%) and captive (6%) pudus. Two previously undescribed sequences, classified in a clade including hemoplasmas from carnivores, were found in one wild pudu each. This study presents the first evidence of the presence of M. ovis-like organisms in Chile and of the susceptibility of pudus to infection with hemoplasmas. Further research is needed to understand the pathologic consequences of this pathogen for pudus, its effects at the population level, and their potential impact on the health small ruminants and other wildlife species in Chile.

Abstract
Deer keds are obligatory hematophagous ectoparasites of birds and mammals. Cervids serve as specific hosts for these insects. However, ked infestations have been observed in non-specific hosts, including humans, companion animals, and livestock. Lipoptena fortisetosa is a weakly studied ectoparasite, but there is evidence to indicate that it continues to spread across Europe. The existing knowledge on deer keds' impact on wildlife is superficial, and their veterinary importance is enigmatic. Lipoptena fortisetosa is a species with vectorial capacity, but potential pathogen transmission has not been assessed. The objective of this study was to evaluate the prevalence of selected pathogens in L. fortisetosa collected from cervids and host-seeking individuals in the environment. Out of 500 acquired samples, 307 (61.4%) had genetic material from at least one tested pathogen. Our research suggests that L. fortisetosa may be a potential vector of several pathogens, including A. phagocytophilum, Babesia spp., Bartonella spp., Borellia spp., Coxiella-like endosymbionts, Francisiella tularensis, Mycoplasma spp., Rickettsia spp., and Theileria spp.; however, further, more extensive investigations are required to confirm this. The results of the study indicate that keds can be used as biological markers for investigating the prevalence of vector-borne diseases in the population of free-ranging cervids.

[PMID: 32712811 PMCID: PMC7382646 DOI: 10.1007/s11250-020-02357-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2019] [Accepted: 07/21/2020] [Indexed: 11/30/2022]
Abstract
Mycoplasma ovis (formerly Eperythrozoon ovis) is an epierythrocytic parasitic bacterium of small ruminants known as haemotropic mycoplasma, which is transmitted mechanically by biting flies and contaminated instruments. Acute mycoplasmosis causes severe haemolytic anaemia and mortality in young animals. At the same time, chronic disease may produce mild anaemia and varying degrees of morbidity depending on several factors, including age, reproductive status, the plane of nutrition, immunological status and the presence of concurrent infection. Haemotropic Mycoplasma ovis is currently recognised as an emerging zoonotic pathogen which is widely distributed in the sheep and goat producing areas of tropics and subtropics, where the disease is nearly endemic. Human infection has been reported in pregnant women, immunocompromised patients and people exposed to animals and arthropods. The current diagnosis of haemoplasma relies on microscopic evaluation of Giemsa-stained blood smear and PCR. Although there are few published reports on the incidence of haemotropic Mycoplasma ovis infection of small ruminants in Malaysia, information on its prevalence, risk factors, severity and economic impacts is grossly inadequate. Therefore, a large-scale survey of small ruminant flocks is necessary to elucidate the current seroprevalence status and molecular characteristics of haemotropic M. ovis infection in Malaysia using ELISA and PCR sequencing technologies. In the future, surveillance programs, including vector forecast, quarantine, monitoring by periodic surveys and public enlightenment, will limit the internal and transboundary spread of M. ovis, enhance control efforts and mitigate production losses in Malaysia.

Abstract
We here present annotated lists of names of Candidatus taxa of prokaryotes with ranks between subspecies and class, proposed between the mid-1990s, when the provisional status of Candidatus taxa was first established, and the end of 2018. Where necessary, corrected names are proposed that comply with the current provisions of the International Code of Nomenclature of Prokaryotes and its Orthography appendix. These lists, as well as updated lists of newly published names of Candidatus taxa with additions and corrections to the current lists to be published periodically in the International Journal of Systematic and Evolutionary Microbiology, may serve as the basis for the valid publication of the Candidatus names if and when the current proposals to expand the type material for naming of prokaryotes to also include gene sequences of yet-uncultivated taxa is accepted by the International Committee on Systematics of Prokaryotes.

Abstract
PURPOSE Haemoparasitic diseases are among the important factors that threaten cattle health and productivity especially in the sub-Saharan region. In Nigeria, their detection using sensitive molecular techniques is scanty. This study was designed to investigate and to reevaluate the repertoire of haemoparasites of cattle in Ibadan, Nigeria with a comparative evaluation of light microscopy (LM) and polymerase chain reaction (PCR) methods. METHODS Blood samples from 100 cattle slaughtered at Ibadan abattoirs were examined using LM and PCR techniques for haemoparasite detection. The PCR reactions using three primer sets targeting the 16S rRNA genes for Hemoplasma spp. and Anaplasma/Ehrlichia spp. and 18S rRNA genes of Babesia/Theleiria spp. were done. A few randomly selected amplicons from each set were sequenced and analysed. RESULTS A total infection rate of 34% by LM including Hemoplasma spp. (17%), Anaplasma spp. (16%), microfilaria (5%) and Trypanosoma spp. (12%) was recorded. While, 86% positivity was recorded with PCR amplification as follows: Hemoplasma spp. (64%), Babesia/Theleiria spp. (46%) and Anaplasma/Ehrlichia spp. (5%). Comparison of LM and PCR findings showed that no LM Anaplasma spp.-positive samples and 7 out of the 17 LM hemoplasma-positive cattle were confirmed by PCR. In addition, LM led to misdiagnosis of 46 Babesia/Theleiria spp.-positive samples. Amplicon sequencing and phylogenetic analysis of Babesia/Theileria spp.-positive samples revealed Theileria velifera and Theileria annulata. In the Anaplasma/Ehrlichia spp.-positive samples, only Anaplasma marginale was characterized. Mycoplasma wenyonii, "Candidatus Mycoplasma haemobos" and Pseudomonas fluorescens like were characterized among the hemoplasma-infected cattle. CONCLUSIONS The first report of "Candidatus Mycoplasma haemobos" and Pseudomonas fluorescens like in Nigerian cattle is herewith documented. The alarming LM misdiagnosis of haemoparasites during this study confirms its limitations as it fails to identify many parasites and emphasizes the need for inclusion of molecular techniques to improve their detection. The study also shows for the first time the high prevalence of haemotropic mycoplasma in Nigerian cattle via molecular diagnostic methods, thus indicating a strong need for the investigation of their zoonotic implications.

Abstract
Cervids represent a mammal group which plays an important role in the maintenance of ecological balance. Recent studies have highlighted the role of these species as reservoirs for several arthropods-borne pathogens. Globally, hemotropic mycoplasmas (haemoplasmas) are emerging or remerging bacteria that attach to red blood cells of several mammals species causing hemolytic anaemia. Therefore, the aim of this study was to investigate the occurrence and assess the phylogenetic positioning of Mycoplasma ovis in free-ranging deer from Brazil. Using a polymerase chain reaction targeting the 16S rRNA region, 18 (40%) out of 45 sampled deer were positive to M. ovis. Among the nine sequences analysed, four distinct genotypes were identified. The sequences detected in the present study were closely related to sequences previously identified in deer from Brazil and the USA. On the other hand, the Neighbour-Net network analysis showed that the human-associated M. ovis genotypes were related to genotypes detected in sheep and goats. The present study shows, for the first time, the occurrence of M. ovis in Mazama gouazoubira and Mazama bororo deer species, expanding the knowledge on the hosts harbouring this haemoplasma species. Once several deer species have your population in decline, additional studies are needed to evaluate the pathogenicity of M. ovis among deer populations around the world and assess its potential as reservoir hosts to human infections.

Abstract
AbstractThe African buffalo (Syncerus caffer), a mammal species whose population is declining, can play a role as a reservoir or carrier of a wide number of arthropod-borne pathogens. Translocation procedures have been used as an alternative approach for species conservation. However, the veterinary aspects of this sort of procedures are extremely important to minimize the impact on animal health. In order to detectBartonellaand haemoplasmas, two important group of bacterial that have an impact in both human and animal health, EDTA whole-blood samples were screened for the presence of these bacterial pathogens by molecular techniques. As a result, a molecular occurrence of 4.1 and 15.4% forBartonellaspp. and haemoplasmas, respectively, was reported among 97 wild buffaloes sampled during a translocation procedure from Marromeu to Gorongosa Reserve, Mozambique. Additionally, phylogenetic analyses of the obtained sequences were conducted. At least, three bovine-associated pathogens, namelyB. bovis,M. wenyoniiand ‘CandidatusM. haemobos’, as well as a probably newBartonellagenotype/species were detected inS. caffer.Further studies are needed in order to determine whether these bacterial species may cause impact in buffaloes and other sympatric ruminant species living in the release site.

Abstract
AIM This study is part of an active surveillance program for monitoring animal health status in endangered species, and was conducted to screen captive Barbary sheep (Ammotragus lervia) for hemoplasma infection. MATERIALS AND METHODS A total of 12 blood samples were collected, DNA extracted and further tested by a pan-hemoplasma polymerase chain reaction protocol. RESULTS Animals were clinically healthy and not infested by ectoparasites. Although housekeeping gene DNA was successfully amplified, all the Barbary sheep samples tested negative for Mycoplasma sp. CONCLUSION Notwithstanding the negative results, molecular pathogen surveys on Barbary sheep and other exotic wild mammals may provide insights regarding infection of endangered species caused by captivity stress in association with exposure to new pathogens worldwide.

Abstract
Hemotropic mycoplasmas (hemoplasmas) are cell-wall deficient, epierythrocytic
bacteria that cause infectious anemia in several mammalian species. The prevalence of
hemoplasma species was examined by screening and species-specific PCR using blood samples
collected from 51 sika deer in Hokkaido, Japan. Molecular analyses were performed for the
16S rRNA, 23S rRNA and RNase P RNA (rnpB) gene sequences. A total of
23/51 (45%) deer DNA samples were positive for hemoplasmas in the screening PCR. Using
species-specific PCR, 12 and 17 samples were positive for ‘Candidatus
Mycoplasma haemocervae’ and ‘Candidatus M. erythrocervae’, respectively.
Sequencing and phylogenetic trees of those three genes indicate that the
‘Candidatus M. haemocervae’ and ‘Candidatus M.
erythrocervae’ detected in Japanese deer are potentially different species from the
cervine hemoplasma found in deer from America and Brazil.

Abstract
Globally, hemotropic Mycoplasma spp. are emerging or re-emerging zoonotic pathogens that affect livestock, wildlife, companion animals, and humans, potentially causing serious and economically important disease problems. Little is known about hemotropic Mycoplasma spp. prevalence, host-specificity, or route of transmission in most species, including wildlife. DNA amplification by PCR targeting the 16SrRNA and the RNaseP genes was used to establish the presence and prevalence of hemotropic Mycoplasma spp. in a white-tailed deer (O. virginianus) population in eastern North Carolina. Sixty-five deer (89%) tested positive for hemotropic Mycoplasma spp. where sequence analysis of the 16SsRNA and the RNaseP genes indicated the presence of at least three distinct species. This study represents the first detection of three distinct hemotropic Mycoplasma species in white-tailed deer and the first report of two novel hemotropic Mycoplasma species.

Abstract
The prevalence of hemotropic mycoplasmas in wild rodents is largely unknown. Here, we report the presence of hemoplasmas in blood samples collected from brown sewer rats (Rattus norvegicus) trapped during rodent control around an animal hospital in Morioka, Japan. We examined nine rats using real-time PCR and end-point PCR, and found one rat (11.1%) that was positive for a hemoplasma infection. The 16S rRNA gene and 16S to 23S rRNA intergenic spacer region of the hemoplasma detected in a wild-caught rat were amplified using PCR. The nucleotide sequences of the PCR products were further determined and compared to those of other hemoplasmas. Our examinations revealed the presence of a hemoplasma that has not previously been described in rodents. The pathogenic traits of this hemoplasma remain unexplored.

Abstract
This is the first report on Mycoplasma infection in wild bears. We report a novel hemotropic Mycoplasma (also called hemoplasma) detected in a free-ranging black bear (Ursus thibetanus japonicus) in Japan. We then used real-time PCR to look for hemoplasma DNA in blood samples collected from 15 bears and found that eight (53%) were positive. Among these eight PCR samples, seven showed a melting temperature of around 85.5°C, while the remaining one showed a single peak at 82.26°C. Almost the entire region of the 16S rRNA gene as well as the 16S-23S rRNA intergenic transcribed spacer (ITS) region from the sample that showed a melting temperature of 82.26°C was successfully amplified by means of end-point PCR. The nucleotide sequences of the 16S rRNA gene and the ITS region were then determined and compared with those of authentic Mycoplasma species. Our examinations revealed the presence of a novel hemoplasma in Japanese black bears.

Abstract
Hemoplasma is a tribal name for epierythrocytic mycoplasmas including Mycoplasma suis and M. parvum which are currently recognized in pigs as causative of porcine hemoplasmosis. Here, we report a real-time PCR assay for differential detection of these swine hemoplasma species by using allelic primers in the16S rRNA gene, and its application to survey for hemoplasma infections in pigs. Universal primers and species-specific primers were designed and evaluated by using swine blood samples positive in hemoplasmas. Mycoplasma suis and M. parvum infections were both confirmed by universal primers, and mixed infections were clearly distinguished by species-specific primers. Further, we applied this real-time PCR assay to 120 swine blood specimens from clinically healthy pigs in eleven farms in Japan, and found six (5.0%) were positive for M. suis and 18 (15.0%) were positive for M. parvum, and three (2.5%) were mixed infection by both hemoplasma species.
