Abstract
Background: Chagas disease or American trypanosomiasis, caused by Trypanosoma cruzi and vectored by triatomines, affects millions of people worldwide. In endemic countries including Mexico, infections in domestic animals, such as dogs, may affect the risk of human disease when they serve as a source of infection to vectors that subsequently infect humans. Materials and Methods: We conducted a cross-sectional study of 296 dogs from two cities near the northern and southern borders of Mexico: Reynosa, Tamaulipas, and Tuxtla Gutierrez, Chiapas. Infection was measured based on testing of blood using T. cruzi quantitative PCR (qPCR) and up to three antibody detection assays. The StatPak immunochromatographic assay was used to screen samples and the indirect fluorescent antibody (IFA) and multiplex microsphere immunoassay (MIA) tests were used as secondary tests on all samples that screened positive and a subset of negatives. Serologic positivity was defined based on reactivity on at least two independent tests. Results: Of the 280 samples tested for parasite DNA, two (0.7%) were positive, one of which (0.4%) was confirmed as T. cruzi discrete typing unit TcIV. Overall, 72 (24.3%) samples were reactive for T. cruzi antibodies via StatPak of which 8 were also positive using MIA and 2 were also positive using IFA (including one of the PCR-positive dogs). Overall, nine dogs (3.4%) met study criteria of positivity based on either/both serology or PCR tests. Positive dogs were found in both regions of Mexico; five (2.7%) from Reynosa and four (3.6%) from Tuxtla Gutierrez. We found no association between infection status and state of origin, sex, age group, breed group, neighborhood, and whether other pets lived in the home. Conclusion: Our results re-emphasize dogs' utility as sentinels for T. cruzi in Mexico and underscore the need for improved veterinary diagnostic tests and parasite surveillance at the household level in endemic countries.

Abstract
Rotavirus A (RVA) causes gastroenteritis in humans and animals. The zoonotic potential of RVA has been reported and raises major concerns, especially in animal-human interface settings. The study aimed to characterize and investigate the genetic diversity among RVAs in dogs and cats in Thailand. We collected 572 rectal swab samples from dogs and cats in Bangkok animal hospitals from January 2020 to June 2021. The one-step RT-PCR assay detected RVAs in 1.92% (11/572) of the samples, with 2.75% (8/290) in dogs and 1.06% (3/282) in cats. Two canine RVA and one feline RVA were subjected to whole genome sequencing. Our results showed that all three viruses were identified as RVA genotype G3P[3]. The genetic constellation of RVAs is unique for different species. For canine RVAs is G3-P [3]-I3-R3-C3-M3-A9-N2-T3-E3-H6, while Feline RVA is G3-P [3]-I8-R3-C3-M3-A9-N3-T3-E3-H6. Notably, both canine and feline RVAs contained the AU-1 genetic constellation with multiple reassortments. The results of phylogenetic, genetic, and bootscan analyses showed that canine RVAs may have reassorted from dog, human, and cat RVAs. While feline RVA was closely related to RVAs in humans, bats, and simians. This study provided genetic characteristics and diversity of RVAs in dogs and cats and suggested possible multiple reassortments, suggesting the zoonotic potential of the viruses. Thus, public health awareness should be raised regarding the zoonotic potential of RVAs in dogs and cats. Further studies on RVAs on a larger scale in dogs and cats in Thailand are needed.

Abstract
Canine bufavirus (CBuV) was reported in domestic dogs worldwide. We conducted a survey of canine bufavirus in domestic dogs in Thailand from September 2016 to October 2022. Rectal swab samples (n = 531) were collected from asymptomatic dogs and dogs with gastroenteritis signs. The samples were tested for CBuV using PCR with specific primers to the VP1/VP2 gene, and 9.42% (50/531) was CBuV positive. Our findings showed that CBuVs could be detected in both symptomatic and healthy dogs. The Thai CBuVs were found in dogs from different age groups, with a significant presence in those under 1 year (12.60%) and dogs aged 1-5 years (7.34%) (p < 0.05), suggesting a high prevalence of Thai CBuVs in dogs under 5 years of age. We performed complete genome sequencing (n = 15) and partial VP1/VP2 sequencing (n = 5) of Thai CBuVs. Genetic and phylogenetic analyses showed that whole genomes of Thai CBuVs were closely related to Chinese and Italian CBuVs, suggesting the possible origin of Thai CBuVs. The analysis of VP1 and VP2 genes in Thai CBuVs showed that 18 of them were placed in subgroup A, while only 2 belonged to subgroup B. This study is the first to report the detection and genetic characterization of CBuVs in domestic dogs in Thailand. Additionally, surveillance and genetic characterization of CBuVs in domestic animals should be further investigated on a larger scale to elucidate the dynamic, evolution, and distribution of CBuVs.

Abstract
To understand the epizootiologic characteristics of pathogens and opportunistic infections in one Beagle dog production colony and three research facilities, viruses and mycoplasma were detected in 1777 samples collected from Beagle dogs in China by polymerase chain reaction/reverse transcription polymerase chain reaction, and bacteria were isolated and identified by 16S rRNA sequence analysis. In addition, genotyping of the major circulating viruses was carried out by amplification of gene fragments and homology analysis. Canine coronavirus (CCoV), Escherichia coli, canine parvovirus (CPV), Bordetella bronchiseptica, Clostridium perfringens, Mycoplasma cynos, Klebsiella pneumoniae, Streptococcus canis, canine astrovirus (CaAstV), canine kobuvirus (CaKV), Pseudomonas aeruginosa, Proteus mirabilis, Macrococcus canis, Pasteurella canis, canine bocavirus (CBoV) and canine adenovirus (CAdV) were detected in the samples. Single, double, triple and quadruple infections accounted for 6.6%, 1.4%, 1.2% and 0.96% of samples, respectively. CCoV strains in 81 samples included three genotypes, CCoV-I, CCoV-IIa and CCoV-IIb, by analysis of S gene. The rate of single infection of CCoV-I, CCoV-IIa or CCoV-IIb was 19%, 38% or 7.4% respectively. The double and triple infection rates of CCoV were 32.8% and 2.5% respectively. All CPV strains in 36 samples belonged to CPV-2c. There were three amino acid differences in the Fiber protein of CAdV-positive sample QD2022, compared with the reference strain Toronto A26/61 and the vaccine strain YCA-18. These results suggest that CCoV and CPV are primary infectious agents, and that these two viruses were often identified in mixed infections, or coinfections alongside mycoplasma or other bacteria. These results will provide the basis for improvements in prevention and control of naturally occurring infectious diseases in Beagle dog production colonies and research facilities.

Abstract
There is a dearth of information on the molecular epidemiology of rotaviruses in pets in Brazil. The aim of this study was to monitor rotavirus infections in household dogs and cats, determine full-genotype constellations, and obtain data on evolutionary relationships. Between 2012 and 2021, 600 fecal samples from dogs and cats (516 and 84, respectively) were collected at small animal clinics in São Paulo state, Brazil. Rotavirus screening was conducted using ELISA, PAGE, RT-PCR, sequencing, and phylogenetic analysis. Rotavirus type A (RVA) was detected in 0.5% (3/600) of the animals. No non-RVA types were detected. The three canine RVA strains were found to have a novel genetic constellation, G3-P[3] -I2-R3-C2-M3-A9-N2-T3-E3-H6, which has never been reported in dogs. As expected, all of the viral genes, except those encoding NSP2 and VP7, were closely related to the corresponding genes from canine, feline, and canine-like-human RVA strains. A novel N2 (NSP2) lineage was identified, grouping together Brazilian canine, human, rat and bovine strains, suggesting that genetic reassortment had occurred. Uruguayan G3 strains obtained from sewage contained VP7 genes that were phylogenetically close to those of the Brazilian canine strains, which suggests that these strains are widely distributed in pet populations in South American countries. For the NSP2 (I2), NSP3 (T3), NSP4 (E3), NSP5 (H6), VP1 (R3), VP3 (M3), and VP6 (I2) segments, phylogenetic analysis revealed possibly new lineages. The epidemiological and genetic data presented here point out the necessity for collaborative efforts to implement the One Health strategy in the field of RVA research and to provide an updated understanding of RVA strains circulating canines in Brazil.

Abstract
Viral gastroenteritis is a common clinical problem in dogs and group A rotavirus (RVA) is one of the agents involved in this etiology. It mainly affects dogs in the first 6 months of life, and these animals are considered an important reservoir and potential transmitters of the virus to other susceptible hosts, such as humans. Among the different types of RVA, G3 is the most detected in dogs, and this genotype is also involved in infections in other animals, including humans. Thus, the present study aims to investigate the presence of RVA in samples of dogs from a public kennel. A total of 64 fecal samples from dogs with diarrhea were analyzed, collected from April 2019 to March 2020, from the kennel of the Zoonosis Control Center, located in Belém, a city in the North of Brazil. The extracted genetic material was subjected to reverse transcription followed by real-time PCR (RT-qPCR); the positives were tested by RT-PCR with a specific primer for the RVA VP7 gene, after nucleotide sequencing and phylogenetic analysis. One sample was subjected to high-performance sequencing. A positivity of 7.8% (5/64) was observed for RVA, all characterized as G3, grouping in the G3-III lineage, with greater similarity to human samples. Different regions of the RVA genome fragments were found. These results emphasize the need for animal health surveillance to better understand the global strain dispersion of RVA and elucidate possible interspecies transmission events, monitoring the genetic diversity of this pathogen.

Abstract
Viral pathogens are the primary cause of canine gastroenteritis. However, few structured comprehensive studies on the viral etiology of canine gastroenteritis have been conducted. In this study, 475 rectal swabs collected over three years (2018-2021) from clinical canine gastroenteritis cases were screened for the presence of six major enteric viruses - canine parvovirus 2 (CPV-2), canine distemper virus (CDV), canine adenovirus 2 (CAdV-2), canine coronavirus (CCoV), canine astrovirus (CaAstV), and canine rotavirus (CRV) - by real-time PCR. The most frequently detected virus was CPV-2, which was present in 64.8% of the samples (subtype 2a, 21.1%; 2b, 77.4%; 2c, 1.5%), followed by CDV (8%), CaAstV (7.2%), CCoV (5.9%), and CAdV-2 (4.6%). Two to four of these viruses in different combinations were found in 16.8% of the samples, and CRV was not detected. The complete genome sequences of Indian isolates of CDV, CCoV, and CaAstV were determined for the first time, and phylogenetic analysis was performed. This study highlights the need for routine prophylactic vaccination with the appropriate vaccines. Notably, 70.3% of animals vaccinated with DHPPiL were found to be positive for at least one virus. Hence, regular molecular analysis of the prevalent viruses is crucial for addressing vaccination failures.

Abstract
Rotaviruses (RVs) are endemic in swine populations, and all swine herds certainly have a history of RV infection and circulation. Rotavirus A (RVA) and C (RVC) are the most common among all RV species reported in swine. RVA was considered most prevalent and pathogenic in swine; however, RVC has been emerging as a significant cause of enteritis in newborn piglets. RV eradication from swine herds is not practically achievable, hence producers’ mainly focus on minimizing the production impact of RV infections by reducing mortality and diarrhea. Since no intra-uterine passage of immunoglobulins occur in swine during gestation, newborn piglets are highly susceptible to RV infection at birth. Boosting lactogenic immunity in gilts by using vaccines and natural planned exposure (NPE) is currently the only way to prevent RV infections in piglets. RVs are highly diverse and multiple RV species have been reported from swine, which also contributes to the difficulties in preventing RV diarrhea in swine herds. Human RV-gut microbiome studies support a link between microbiome composition and oral RV immunogenicity. Such information is completely lacking for RVs in swine. It is not known how RV infection affects the functionality or structure of gut microbiome in swine. In this review, we provide a detailed overview of genotypic diversity of swine RVs, host-ranges, innate and adaptive immune responses to RVs, homotypic and heterotypic immunity to RVs, current methods used for RV management in swine herds, role of maternal immunity in piglet protection, and prospects of investigating swine gut microbiota in providing immunity against rotaviruses.

Abstract
Rotaviruses can infect multiple animal species and have the potential for cross-recombination based on the segmented genome characteristics. To study the intra-host recombination and zoonotic potential of group A canine rotavirus (CRV), 438 samples were collected from domestic dogs in six animal hospitals and from stray dogs from October 2019 to May 2021 in Wuhan, China. Seven of the samples were positive (7/438) for group A CRV from which a CRV strain was successfully isolated in MA-104 cells. The genotype of the isolated strain was characterized by whole-genome sequencing showing that the genotype was group A CRV G3P[3]. According to the Rotavirus Classification Working Group (RCWG), the genomic constellation of the isolated CRV was G3-P[3]-I3-R3-C3-M3-A9-N2-T3-E3-H6, which belongs to the AU-1-like group with gene segments of AU-1-like and Cat 97-like strains. Based on the phylogenetic analysis of the 11 gene segments, we found that the different segments of the isolated group A CRV were closely related to several reassortment rotaviruses from different animal sources and bat strains. Based on the analysis of the molecular evolution and genetic characteristics, we concluded that the isolated strain might be a reassortment strain. These data further enrich our understanding of rotavirus molecular evolution and genetic characteristics in China.

Abstract
Rotaviruses species A (RVA) are etiological agents of diarrhoea and are considered zoonotic viruses; yet the epidemiology of RVA among pet animals is largely unknown. RVA was detected in 38 of 308 faecal samples (12.3%) from pet, sheltered, or stray dogs and cats in two municipalities of Rio de Janeiro state, Brazil. The results indicated that these viruses are common in canine and feline populations and underscore the importance of improved monitoring of common pathogens in companion animals, with increased awareness of the potential for interspecies transmission events.

Abstract
Background Astrovirus, Norovirus and Sapovirus are widely distributed viruses in humans and animals worldwide. They have frequently been associated with disease, mainly of gastroenteric nature. In dogs, these viruses have been detected both in symptomatic and asymptomatic animals, mainly of young age. Methods In the present epidemiologic study, we investigated the presence of canine Astrovirus (CAstV), canine Norovirus (canine NoV) and canine Sapovirus (Canine SaV) in saliva and stools of 201 domestic dogs originating from throughout Greece, based on two different molecular methods, i.e. conventional and SYBR-Green Real-time RT-PCR. The samples derived from young and adult asymptomatic and symptomatic animals. CAstV was detected in 15/201 (7.5%) and 29/201 (15%) of the examined dogs using conventional RT-PCR and SYBR-Green Real time RT-PCR, respectively. Results The prevalence of the virus was higher at healthy dogs, with a slight discrepancy of the two methods on the aspect of age (67% young dogs with the method of conventional RT-PCR, versus 52% adult positive dogs with the method of SYBR-Green Real-time RT-PCR). Canine SaV was detected in 52/201 (23%) of the dogs (mainly young and asymptomatic), with the method of SYBR-Green Real-time RT-PCR only, while canine NoV was not detected in any sample with either of the two methods applied. Sequencing of the CAstV positive samples resulted in the acquisition of one CAstV sequence. Phylogenetic analysis confirmed the results, clustering the CAstV sequence with homologous canine hosting sequences from other countries. Conclusions CAstV and Canine SaV were proved to circulate in Greek dogs. SYBR-Green Real time RT-PCR showed greater sensitivity in the detection of these viruses. Additionally, we were able to specify the CAstV strain that circulates in Greece, through phylogenetic analysis. To our knowledge, this is the first epidemiological study of CAstV and canine SaV in dogs in Greece, as well as the first time detected in dogs from Greece.

Abstract
Background Canine Parvovirus type 2 (CPV-2) is a member of the Parvoviridae family with a global distribution and causes pathogenicity in puppies aged from 6 weeks to 6 months. It should be noted that Maternally Derived Antibodies (MDA) have protection against CPV-2 in the first weeks of puppies’ life. However, MDA declines with age. The most important influential factor is timely vaccination against CPV-2. Methods In this study, 24 healthy 8-week-old terrier puppies were selected and divided into three identical groups based on a randomized, double-blind comparative trial. One of which was called the control group that was injected with the physiological serum. The second group was the group A that was vaccinated by the vaccine provided by Biocan DHPPi+L (Bioveta, Czech). The third group was group B that was vaccinated by the vaccine of Duramune Max 5 + LCI / GP (Fort Dodge Animal Health, USA) from 8 to 16 weeks of their life at every 4 weeks. Then serum samples were analyzed with HI and ELISA tests. Results The MDA titer was protective in some puppies until 18 weeks of age. Also, after the first vaccination, all puppies had a protective titer against CPV-2, and Duramune vaccine had seroconverted after the first injection and Biocan had seroconverted after the second injection. Conclusions It is recommended that to reduce the risk of vaccine failure: such as the MDA titer should be measured in puppies before designing a vaccination schedule.

Abstract
Bloody diarrhea is a common condition in dogs, but studies evaluating the enteropathogens involved specifically in adult dogs are scarce. In the present study, stool samples from 45 adult dogs with bloody diarrhea were evaluated for the four enteric organisms mainly reported in these cases: canine parvovirus type 2 (CPV-2), Clostridioides difficile, Clostridium perfringens, and Salmonella spp. In addition, the samples were also tested for coronavirus, rotavirus, Giardia spp., and Escherichia coli pathotypes to provide a better understanding of possible co-occurrence. Vaccination status, diet, and clinical outcome were also obtained when available. CPV-2b was identified in 17 dogs (37.8%), being the most frequent cause of bloody diarrhea, including completely vaccinated adult dogs. Toxigenic C. difficile and C. perfringens netF+ were detected in 6 (13.3%) and 5 (11.1%) dogs, in some cases in a co-occurrence with other enteric organisms. Three fatal cases of salmonellosis were identified in dogs fed a raw meat-based diet, raising the risks associated with this increasing practice.

Abstract
Canine parvovirus type 2 (CPV-2) is one of the most relevant pathogens associated with enteritis in dogs and is frequently reported in association with the detection of other pathogens in faeces. In this study the concomitant presence of Canine circovirus (CanineCV) and Canine adenovirus (CAdV) DNA in faecal or intestine samples of 95 dogs with parvovirus enteritis sampled in Italy (1995–2017) was investigated and the viruses identified were genetically characterised. Potential correlations with the antigenic variant of CPV-2 and with signalment data and outcome were evaluated. Twenty-eight of 95 (29.5%) CPV-2 infected dogs tested positive to other viruses: 7/28 were also positive to CanineCV, 1/28 to CAdV-1, 18/28 to CAdV-2, 1/28 to CanineCV and CAdV-2, and 1/28 to CAdV-1 and CAdV-2. The frequency of CAdV DNA detection and coinfections was significantly higher in purebred dogs compared to mixed breed ones (P = 0.002 and 0.009, respectively). The presence of coinfection was not associated with any other relevant data available, including CPV-2 variant and final outcome. The detection of CanineCV in a dog sampled in 2009 allowed to backdating its circulation in dogs. The eight CanineCV completely sequenced were phylogenetically related to the CanineCV identified in dogs, wolves and a badger from Europe, USA, Argentina and China. Nine CAdV were partially sequenced and phylogenetic analysis showed a separate branch for the oldest CAdV-2 identified (1995). From the results obtained in this study population, CanineCV and CAdV coinfections in dogs with parvoviral enteritis did not result in more severe disease.

Abstract
A duplex SYBR Green I-based real-time PCR assay was established for the simultaneous detection of canine kobuvirus (CaKoV) and canine astrovirus (CaAstV). This assay can easily distinguish the two viruses according to their different melting temperatures (Tm) of 80 °C for CaKoV and 86.5 °C for CaAstV; other canine enteroviruses used as controls showed no specific melting peaks. The detection limit of this assay was determined to be 101 copies/μL for both viruses. This method exhibited high repeatability and reproducibility, with a coefficient of variation less than 1.5 %. A total of 48 fecal samples were collected for clinical testing by real-time PCR and confirmed by sequencing. Real-time PCR assay showed a 10.4 % CaKoV-positive rate and a 4.2 % CaAstV-positive rate, and the positive rate of co-infection of the two viruses was 2.1 %, which was consistent with the sequencing results. This assay has many advantages over conventional PCR: it is rapid, sensitive, specific, and reliable for detecting these two viruses in one sample, and it can be used as a tool to detect CaKoV and CaAstV infection or co-infection in clinical settings.

Abstract
Objective: A clinico-epidemiological study was conducted at two veterinary hospitals in Dhaka to evaluate the prevalence of parvoviral enteritis (PVE) in dogs and feline panleukopenia (FPL) in cats, to detect factors associated with them, and to identify their common clinical signs. Materials and Methods: Clinico-epidemiological data were collected for a total of 88 dogs and 129 cats which were presented to the hospitals, entered into MS excel 2010, and then transferred to STATA-14 software for conducting descriptive and univariable statistical analyses (Fisher’s exact test). The maps showing the spatial distribution of PVE and FPL were produced by using QGIS software version 2.18.13. Results: PVE in dogs and FPL in cats had the highest prevalence compared to other diseases (34.1%; 95% confidence interval: 24.3–44.9; N = 88 and 20.2%; 95% confidence interval: 13.6–28.1; N = 129, respectively). Young age (43.8%), poor body condition (58.4%), and exotic breeds (44.2%) were significantly associated with the occurrence of PVE (p ≤ 0.05). Poor body condition (27.8%) and non-vaccination status (26.7%) were associated with FPL (p ≤ 0.05). Both PVE and FPL showed clinical signs of being off-feed, frequent vomiting, weakness, and moderate dehydration. Conclusion: The high prevalence of PVE and FPL indicates that they are common in dogs and cats in Dhaka, Bangladesh. The factors related to PVE are young age, exotic breed, and poor body condition score (BCS), and FPL are poor BCS and non-vaccination. Specific measures such as care during younger age, good nutrition, and routine vaccination are needed to prevent and control PVE and FPL in Dhaka’s dog and cat population.

Abstract
From September 2016 to January 2019, we collected 710 rectal swabs from both healthy and sick dogs from small animal hospitals in 5 provinces of Thailand. The samples were tested for canine rotavirus group A (CRV) by using one-step RT-PCR specific to the VP6 gene. Our results showed that 0.70% (5/710) were positive for CRV. The five CRVs were then characterized by whole-genome sequencing. Our results showed that the genotype of Thai CRVs is G3P[3], which is the predominant genotype reported in dogs. The Thai CRVs posed a novel genetic constellation 'G3-P[3]-I3-R3-C3-M3-A9-N2-T3-E3-H6', which has never been reported in CRVs from dogs but has been reported in rotaviruses from humans. Based on phylogenetic analysis, the Thai CRVs are the result of multiple reassortments in which gene segments might have originated from human and bat rotaviruses and suggests the zoonotic potential of the virus.

Abstract
Canine kobuvirus (CaKoV), a newly described virus, is the causative agent of gastroenteritis in dogs. In this study, 57 fecal samples from dogs with diarrhea in Anhui Province, eastern China, were collected. Among these, five samples were identified to be infected with CaKoV, by polymerase chain reaction targeting the CaKoV 3D gene. The five CaKoV strains were subjected to phylogenetic analysis. The sequences of VP1 from the five CaKoV strains were 93.6%–96.1% identical to each other and 91.75%–97.95% identical to other reported CaKoV VP1 sequences. In addition, the complete genome of one strain was successfully amplified and sequenced. The genome consisted of 8223 nucleotides and shared 94.6%–97.0% nucleotide and 93.1%–94.0% amino acid sequence identity with other CaKoV isolates. Phylogenetic analysis revealed that the CaKoV strain from Anhui Province was similar to other Chinese strains, and it was more closely related to feline and mouse kobuviruses than to sheep and bovine kobuviruses. Interestingly, all of the CaKoV-positive samples were coinfected with canine parvovirus. The finding of CaKoV infection in dogs with diarrhea and coinfection with canine parvovirus are a cause for concern and highlight the need for management and preventive measures.

Abstract
Canine kobuviruses (CaKoV) have been found in healthy and diarrheic dogs as well as asymptomatic wild carnivores in various countries. In order to investigate the prevalence and evolution of CaKoV in Tangshan, China, 82 dog fecal samples from pet hospitals in Tangshan were subjected to RT-PCR targeting a segment of the 3D gene of CaKoV. Using this method, we identified CaKoV in 14 samples (17.07%, 14/82). Of the CaKoV-positive samples, 78.57% (11/14) and 50% (7/14) were positive for canine parvovirus and canine coronavirus, respectively. The nucleotide sequences of the 14 strains 96.6%–100% identical to each other and 77.6%–99.2% identical to representative sequences from the NCBI GenBank database. We also amplified the 14 VP1 gene sequences and found that they were 93.3%–99.6% identical to each other and 73.3%–97.8% identical to representative sequences from the NCBI GenBank database. Phylogenetic analysis revealed that the 14 CaKoV strains from Tangshan are closely related to those identified in China and Thailand and display less similarity to those found in Africa, the United States, and Europe. Our data suggest that CaKoV circulated in young pet dogs in Tangshan and displays a high co-infection rate with CCoV and CPV. However, the relationship between the three viruses and their roles in the host requires further investigation.

Abstract
The World Small Animal Veterinary Association Vaccination Guidelines Group has produced global guidelines for small companion animal practitioners on best practice in canine and feline vaccination. Recognising that there are unique aspects of veterinary practice in certain geographical regions of the world, the Vaccination Guidelines Group undertook a regional project in Latin America between 2016 and 2019, culminating in the present document. The Vaccination Guidelines Group gathered scientific and demographic data during visits to Argentina, Brazil and Mexico, by discussion with national key opinion leaders, visiting veterinary practices and review of the scientific literature. A questionnaire survey was completed by 1390 veterinarians in five Latin American countries and the Vaccination Guidelines Group delivered continuing education at seven events attended by over 3500 veterinarians. The Vaccination Guidelines Group recognised numerous challenges in Latin America, for example: (1) lack of national oversight of the veterinary profession, (2) extraordinary growth in private veterinary schools of undetermined quality, (3) socioeconomic constraints on client engagement with preventive health care, (4) high regional prevalence of some key infectious diseases (e.g. feline leukaemia virus infection, canine visceral leishmaniosis), (5) almost complete lack of minimal antigen vaccine products as available in other markets, (6) relative lack of vaccine products with extended duration of immunity as available in other markets, (7) availability of vaccine products withdrawn from other markets (e.g. Giardia vaccine) or unique to Latin America (e.g. some Leishmania vaccines), (8) accessibility of vaccines directly by pet owners or breeders such that vaccination is not delivered under veterinary supervision, (9) limited availability of continuing education in veterinary vaccinology and lack of compulsion for continuing professional development and (10) limited peer‐reviewed published scientific data on small companion animal infectious diseases (with the exception of leishmaniosis) and lack of support for such academic research. In this document, the Vaccination Guidelines Group summarises the findings of this project and assesses in evidence‐based fashion the scientific literature pertaining to companion animal vaccine‐preventable diseases in Latin America. The Vaccination Guidelines Group makes some recommendations on undergraduate and postgraduate education and academic research. Recognising that current product availability in Latin America does not permit veterinarians in these countries to vaccinate according to the global World Small Animal Veterinary Association guidelines, the Vaccination Guidelines Group makes a series of “pragmatic” recommendations as to what might be currently achievable, and a series of “aspirational” recommendations as to what might be desirable for the future. The concept of “vaccine husbandry” is addressed via some simple guidelines for the management of vaccine products in the practice. Finally, the Vaccination Guidelines Group emphasises the global trend towards delivery of vaccination as one part of an “annual health check” or “health care plan” that reviews holistically the preventive health care needs of the individual pet animal. Latin American practitioners should transition towards these important new practices that are now well embedded in more developed veterinary markets. The document also includes 70 frequently asked questions and their answers; these were posed to the Vaccination Guidelines Group during our continuing education events and small group discussions and should address many of the issues surrounding delivery of vaccination in the Latin American countries. Spanish and Portuguese translations of this document will be made freely available from the on‐line resource pages of the Vaccination Guidelines Group.

Abstract
Canine parvovirus type 2 (CPV-2) infection is the most lethal disease of dogs with higher mortality in puppies worldwide. In today's world, dogs are an integral part of our communities as well as dogs breeding and rearing has become a lucrative business. Therefore, a fast, accurate, portable, and cost-effective CPV-2 detection method with the ability for on-site detection is highly desired. In this study, we for the first time proposed a nanosystem for CPV-2 DNA detection with RNA-guided RNA endonuclease Cas13a, which upon activation results in collateral RNA degradation. We expressed LwCas13a in prokaryotic expression system and purified it through nickel column. Activity of Cas13a was verified by RNA-bound fluorescent group while using a quenched fluorescent probe as signals. Further Cas13a was combined with Recombinase polymerase amplification (RPA) and T7 transcription to establish molecular detection system termed specific high-sensitivity enzymatic reporter un-locking (SHERLOCK) for sensitive detection of CPV-2 DNA. This nanosystem can detect 100 amol/L CPV-2 DNA within 30 min. The proposed nanosystem exhibited high specificity when tested for CPV-2 and other dog viruses. This CRISPR-Cas13a mediated sensitive detection approach can be of formidable advantage during CPV-2 outbreaks because it is time-efficient, less laborious and does not involve the use of sophisticated instruments.

Abstract
Eighty-three wild and domestic carnivores of nine species from Janos Biosphere Reserve (JBR), Mexico, were tested by serologic and molecular assays to determine exposure and infection rates of carnivore protoparvovirus 1. Overall, 50.8% (33/65) of the wild carnivores and 100% (18/18) of the domestic dogs tested were seropositive for Canine protoparvovirus 1 (CPV), while 23% (15/65) of the wild carnivores and 22.2% (4/18) of the domestic dogs were PCR positive for CPV. Phylogenetic analysis confirmed circulation of CVP-2 with residues 426 Asn (CPV2a = 1/19) and 426 Glu (CPV-2c = 18/19) among carnivores in JBR. The prevalence of both PCR positivity and antibodies to CPV varied significantly among wild host species. Of the six identified haplotypes, three were unique to kit foxes (Vulpes macrotis) (the species with higher haplotype richness) and two to striped skunks (Mephitis mephitis). The remaining haplotype was shared among all carnivore species including dogs suggesting non-host specificity and bidirectional and continuous viral transmission cycle in the JBR. The phylogenetic similarity of CPV strains from dogs and wild carnivores and the higher prevalence of CPV in wild carnivores captured near towns relative to those captured far from towns suggest that dogs might be an important source of CPV infection for wild carnivores in the JBR. We provide evidence that cross-species transmission occurs at the domestic-wildlife interface in JBR.

Abstract
Background Canine Kobuvirus (CaKoV) has been detected both in healthy and diarrheic dogs and in asymptomatic wild carnivores. In this study, we conducted a survey of CaKoV at small animal hospitals in Bangkok and vicinity of Thailand during September 2016 to September 2018. Results Three hundred and seven rectal swab samples were collected from healthy dogs (n = 55) and dogs with gastroenteritis symptoms (n = 252). Of 307 swab samples tested by using one-step RT-PCR specific to 3D gene, we found CaKoV positivity at 17.59% (54/307). CaKoVs could be detected in both sick (19.44%) and healthy (9.09%) animals. In relation to age group, CaKoV could be frequently detected in younger dogs (25.45%). Our result showed no seasonal pattern of CaKoV infection in domestic dogs. In this study, we characterized CaKoVs by whole genome sequencing (n = 4) or 3D and VP1 gene sequencing (n = 8). Genetic and phylogenetic analyses showed that whole genomes of Thai CaKoVs were closely related to Chinese CaKoVs with highest 99.5% amino acid identity suggesting possible origin of CaKoVs in Thailand. Conclusions In conclusion, this study was the first to report the detection and genetic characteristics of CaKoVs in domestic dogs in Thailand. CaKoVs could be detected in both sick and healthy dogs. The virus is frequently detected in younger dogs. Thai CaKoVs were genetically closely related and grouped with Chinese CaKoVs. Our result raises the concerns to vet practitioners that diarrhea in dogs due to canine Kobuvirus infection should not be ignored.

Abstract
Canine kobuvirus (CaKV) is a member of the Picornaviridae family and the Kobuvirus genus. CaKV was first described in fecal samples from diarrheic dogs in the USA in 2011, with subsequent reports in the UK, Italy, South Korea, China, Tanzania, and Japan. CaKV is frequently identified in feces of animals with or without clinical signs of gastroenteritis. The present study investigated the presence of CaKV in fecal samples from 53 diarrheic dogs from Londrina, southern Brazil. Using a RT-PCR assay, CaKV RNA was identified in three dogs, resulting in an overall occurrence rate of 5.7%. In addition, coinfection with canine parvovirus subtype 2b was detected in all CaKV-positive diarrheic fecal samples. Using a phylogenetic analysis based on the VP1 gene sequence, the Brazilian CaKV field strains were found to be very similar to a previously identified CaKV strain from Brazil that was found in the tissue of a puppy and were also found to be clustered with other CaKV strains detected worldwide and other kobuvirus strains identified in mouse, feline, and human hosts.

Abstract
Gastroenteritis in young animals is a clinical presentation with many infectious and non- infectious aetiologies. We used next generation sequencing (NGS) to investigate the possible infectious causes of gastroenteritis in puppies from a dog kennel in Victoria, Australia. The near complete genome of a canine astrovirus was obtained from pooled faecal samples, and was found to be 94.7% identical with a canine astrovirus detected in the United Kingdom in 2012. The phylogenetic analysis of the capsid gene found similarities to those of canine astroviruses identified in Italy in 2005 and in UK and Hungary in 2012, but distant from that of a canine astrovirus previously identified in Australia in 2012. Thus, different serotypes of canine astrovirus are likely circulating in Australia. The close relationship to European astroviruses also suggested that there had been recent movements of ancestor canine astroviruses between Australia and Europe. NGS also detected other infections in the puppies including several canine papillomaviruses and a canine parvovirus (vaccine strain) as well as a very low level of campylobacter. Canine astrovirus was the probable cause of diarrhoea in these puppies, with the possible involvement of campylobacter bacteria. NGS was effective as a non-targeted method to determine the likely infectious cause of gastroenteritis.

Abstract
Genotype G9 is an emerging genotype among species A rotavirus (RVA) circulating in humans and pigs worldwide. In this study, an RVA strain designated RVA/Dog-tc/CHN/SCCD-A/2017/G9P[23] was isolated in cell culture from a pet dog stool sample with acute diarrhea, and its whole genome was sequenced. The genotype constellation of SCCD-A was G9-P[23]-I5-R1-C1-M1-A8-N1-T1-E1-H1. All genome segments except the VP1 gene were closely related to the genes from porcine RVA strains or porcine-like human RVA strains. On the other hand, the VP1 gene clustered in a distinct lineage only with that of a G5P[6] porcine-like human RVA, preventing the identification of the exact host species origin, but very unlikely to be originated from human RVA. In addition, phylogenetic analysis showed that the G9 VP7 gene of SCCD-A clustered into a novel sublineage within the lineage III of G9. This first isolation of a G9P[23] RVA from a pet dog may justify the exploration of the role dogs play in the interaction of RVA circulating in pigs and humans. First identified G9P[23] group A rotavirus from dog and the genome of RVA/Dog-tc/CHN/SCCD-A/2017/G9P[23]was determined. The strain’s genotype constellation as G9-P[23]-I5-R1-C1-M1-A8-N1-T1-E1-H1. G9P[23] from dog may justify the exploration of the role dogs play in the interaction of RVA circulating in pigs and humans.
