“…Although BuVs have been identified in various hosts, 17,25,26,42,44,50 whether there is a pathogenic role of this virus or they only serve as a commensal agent in the susceptible hosts has not been fully established. Gathering relevant information obtained from observational studies through epidemiological investigations of BuVs may facilitate the understanding of whether BuVs may act as a pathogen.…”

“…The CBuV PCR-positive/ISH-negative result in other organ samples is, therefore, more likely due to hematogenous spreading. Although recent studies have focused on the association of CBuV with enteric disease because this virus belongs to the Parvoviridae family, 7,30 together with speculation of other BuV infections in association with diarrhea in other susceptible hosts, 42,44,48,50 lower amounts of CBuV DNA were identified in the intestine by the qPCR in some affected puppies. Unfortunately, histological findings of CBuV infection associated with intestinal lesions could not be determined in this study due to tissue autolysis.…”

“…25 Similarly, the role of BuV infection in humans and other animals with enteric diseases remains uncertain. 7,19,27,42,50 Notably, BuV DNA detection in the serum and spleen of infected wild shrews and monkeys, 14,44 as well as in respiratory samples obtained from human patients with lower respiratory tract diseases, has also been reported, 51 suggesting either extraintestinal infections or hematogenous spreading of the virus. Recent studies exploring the genetic characterization of CBuV revealed genomic heterogenicity.…”

Canine bufavirus (CBuV) or Carnivore protoparvovirus-3, a nonenveloped DNA virus belonging to the genus Protoparvovirus, family Parvoviridae, has been identified in dogs with respiratory and enteric diseases. Although CBuV detection has been reported in multiple countries, descriptions of pathologic findings associated with infection have not yet been provided. In this study, the authors necropsied 14 dogs (12 puppies and 2 adult dogs) from a breeding colony that died during multiple outbreaks of respiratory diseases. Postmortem investigations revealed extensive bronchointerstitial pneumonia with segmental type II pneumocyte hyperplasia in all necropsied puppies but less severe lesions in adults. With negative results of common pathogen detection by ancillary testing, CBuV DNA was identified in all investigated dogs using a polymerase chain reaction (PCR). Quantitative PCR demonstrated CBuV DNA in several tissues, and in situ hybridization (ISH) indicated CBuV tissue localization in the lung, tracheobronchial lymph node, and spinal cord, suggesting hematogenous spread. Dual CBuV ISH and cellular-specific immunohistochemistry were used to determine the cellular tropism of the virus in the lung and tracheobronchial lymph node, demonstrating viral localization in various cell types, including B-cells, macrophages, and type II pneumocytes, but not T-cells. Three complete CBuV sequences were successfully characterized and revealed that they clustered with the CBuV sequences obtained from dogs with respiratory disease in Hungary. No additional cases were identified in small numbers of healthy dogs. Although association of the bufavirus with enteric disease remains to be determined, a contributory role of CBuV in canine respiratory disease is possible.

“…Subsequently, BuV infections have been reported in diarrhea patients in several countries such as Bhutan, China, France, Finland, Netherlands, South Africa, Thailand and Turkey 4 – 11 . The occurrence of bufavirus infection in humans in those counties ranges from 0.3 to 4% 5 , 12 , 13 . These studies speculated that BuV might cause gastroenteritis in human 6 , 7 , 14 BuV is not strictly found in humans but it has also been reported in several animal species such as rats, shrews, pigs, dogs, bats, and primates 15 – 19 .…”

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.

Human astroviruses (HAstVs) have frequently been detected in individuals with acute gastroenteritis (AGE). However, a precise estimate of the overall prevalence of the virus in children with AGE as well as the possible association of the virus with gastrointestinal complications is not available up to now. The present study estimated the overall prevalence of HAstVs in children with gastrointestinal complications as well as the association between the virus and symptoms. We systematically searched four international databases (PubMed, Scopus, Web of Science, and Google scholar) to find studies on the prevalence of HAstVs in people with AGE published between Jan 2000 and Sep 2021. Analysis of the 223 included studies presented a 4.2% (95% CI 3.8%–4.8%) prevalence of the virus in AGE individuals. Based on case‐control studies, a significant association between these viruses and AGE was detected (OR: 2.059, 95% CI; 1.438–2.949). HAstV‐1 and HAstV‐VA‐2 is the most and least common genotypes in the AGE patients, respectively (59.0%, 95% CI: 52.1%–65.6% vs. 4.9%, 95% CI: 2.6%–9.1%). Due to the statistically significant association between HAstV and gastrointestinal complications, more attention should be paid to these viruses in people with AGE and more studies should employ case‐control design.
