The Thai Journal of Veterinary Medicine
The mosquito-borne filarial nematode parasites Brugia pahangi and B. malayi have been proposed as potential zoonotic pathogens, with dogs and cats being the main reservoir hosts. The monasteries where both stray and semi-domesticated animals live often serve as areas where humans are exposed to these reservoirs. In Thailand, the prevalence of B. pahangi, particularly in infected monastery cats, is underreported. In this study, we investigated B. pahangi prevalence in cats at 24 temples in the Samphran district, Nakhon Pathom province, central Thailand. In total, 196 blood samples were collected from the cats and examined using the hematocrit capillary tube technique. …

Acute diarrhea is a common clinical sign in dogs which the pathogenesis has associated with altered gut microbiome compositions and influenced by diet, environment, and medication. However, the impact of gut microbiome on dog health has still not been well elucidated in Thailand. This study aims to investigate the alterations of the fecal microbiome in dogs with diarrhea (<3 days) compared to healthy dogs. Fresh feces were collected once from each dog, and DNA extraction was performed following the QIAamp DNA stool mini kit protocol. The 16s rRNA gene, then, amplified and analyzed by the next-generation DNA sequencing technology. The results showed a significant reduction of the evenness and Shannon index in dogs with the diarrhea group. The most dominant phylum in healthy dogs, Firmicutes, was markedly declined. Additionally, significant decreases in bacterial abundances were observed in twelve genera. To the best of our knowledge, seven of them were first described in their alterations including Clostridium sensu stricto 1, Lachnospiraceae NKA4136 group, Erysipelatoclostridium, Tyzzerella 3, Alloprevotella and Slackia. Therefore, these findings disclose the new possible biomarkers for intestinal diseases and the effect of ordinary diets on the fecal microbiome in dog health, Thailand.

This study was conducted to investigate the dynamics and evolution of porcine reproductive and respiratory syndrome virus (PRRSV) genotype 1 following its introduction into a herd concurrently infected with both PRRSV genotypes. The results demonstrated that 2 novel genotype 1 groups emerged, termed clusters II and III. The emergence of cluster II suggested that this cluster of genotype 1 virus potentially correlated with the outbreak. Then, cluster III was detected with the disappearance of cluster II. The evolution of the genotype 1 virus from cluster II to cluster III is likely to be associated with immune evasion induced by amino …

Feline coronavirus (FCoV) infection manifests a wide magnitude of clinical symptoms from nonpathogenic mild enteric infection to pathogenic fatal feline infectious peritonitis (FIP). Based on the in vitro properties and antigenic relationship to canine coronavirus (CCoV), FCoVs are classified into type I and II with different continent preference. To investigate the incidence of FCoV infection among cat populations in Thailand during 2010-2011, clinical specimens (103 bodily fluids from 95 FIP clinically suspected cats and 17 feces from 7 healthy cats living in groups and 10 healthy cats living singly) were analyzed by amplification of the 3’UTR gene. Among them, 46% …

We demonstrated the using of the internal transcribed spacer (ITS2) of ribosomal DNA as a tool for identification of medically and veterinary important Muscidae flies in Thailand. A total of 27 fly samples were collected from various regions of Thailand. Six fly species in three subfamilies including Azeliinae (Hydrotaea spinigera), Muscinae (Musca domestica, M. sorbens) and Stomoxyinae (Stomoxys calcitrans, S. indicus and S. sitiens) were identified base on morphological taxonomy. PCR amplicons of the ITS2 gene of these flies varied between 312-377 bp with A+T content of 76.6%. ITS2 sequences of the flies in this study were 93-100% identity to …
