Zika virus (ZIKV), chikungunya virus (CHIKV) and dengue virus (DENV) are emerging and re-emerging arboviral diseases. These viruses are transmitted to humans through the bites of Aedes mosquitoes. Recently, ZIKV infection has been described as an emerging disease in Thailand and many countries, especially in tropical and subtropical areas. Specific drugs and vaccines against these infections are unavailable; therefore, effective disease control relies on vector control measures only. To understand the transmission cycle of these viruses and mosquito vectors, this study is designed to investigate the natural infection of ZIKV, CHIKV and DENV in field-caught mosquitoes by molecular techniques. Adults …

Emergence Of A Classical Variant Of Porcine Epidemic Diarrhea Virus Novel To Thailand Responsible For The Milder Clinical Disease In A Herd Previously Infected With A Pandemic Variant, Gun Temeeyasen, Anchalee Srijangwad, Thitima Tripipat, Angkana Tantituvanont, Dachrit Nilubol

The Thai Journal of Veterinary Medicine

In 2014, porcine epidemic diarrhea (PED) outbreaks characterized by mild clinical disease and low preweaning mortality increased in frequency in Thailand. An outbreak investigation, based on the detection of the classical variant and the allowance of the herd owners, was conducted in 5 swine herds and 25 intestinal samples were submitted from herds with outbreaks of diarrhea for sequencing analysis. PEDV isolation and complete nucleotide sequences of the spike (S) glycoprotein were determined. The PEDV isolate EAS1 was identified. Phylogenetic analysis based on the full-length spike gene demonstrated that EAS1 belonged to the classical variant group with high nucleotide and …


A Preliminary Study On Diversity Of Midgut Microbiota In Aedes Aegypti (Linnaeus) And Culex Quinquefasciatus (Say) Collected From Bangkok, Thailand, Sonthaya Tiawsirisup, Jirinnut Sirijutalak, Mananya Sondang, Manunya Supol, Nut Ansusinha, Ranida Tuanudom, Channarong Rodkhum Dec 2018

The Thai Journal of Veterinary Medicine

Aedes aegypti and Culex quinquefasciatus are important mosquito vectors for many infectious diseases. A number of factors affect the vector competence of these mosquitoes for a specific pathogen. The bacteria harbored in the midgut are known to influence mosquito physiology and can alter the response to various pathogens. Bacteria from the midgut of Ae. aegypti and Cx. quinquefasciatus were cultured and identified using bacteriological and molecular techniques in this study in which two groups of mosquitoes were examined. The first group was laboratory- reared, and the second group were field- collected mosquitoes from Bangkok. Twelve bacterial genera ( i. e. …


Molecular Epidemiology And Antimicrobial Resistance Of Salmonella Spp. Isolated From Broilers And Pigs At Slaughterhouses In Thailand And China, Wenjing Yang, Dusadee Phongaran, Teerarat Prasertsee, Rendong Fang, Patchara Phuektes, Sunpetch Angkititrakul Sep 2018

Molecular Epidemiology And Antimicrobial Resistance Of Salmonella Spp. Isolated From Broilers And Pigs At Slaughterhouses In Thailand And China, Wenjing Yang, Dusadee Phongaran, Teerarat Prasertsee, Rendong Fang, Patchara Phuektes, Sunpetch Angkititrakul

The Thai Journal of Veterinary Medicine

This study aimed to compare the antimicrobial resistance patterns and DNA restriction patterns by PulsedField Gel Electrophoresis (PFGE) between Salmonella spp. isolated from broilers and pigs in Thailand and China. One hundred and sixty six isolates were collected from broilers and pigs at slaughterhouses in Khon Kaen, Thailand (n=106) between February to August 2017 and in Chongqing, China (n=60) between March to October 2015. Antimicrobial susceptibility of the isolates was determined using the disk diffusion method with nine antimicrobial agents. Genotypic diversity of the isolates used PFGE of Xbal-digested chromosomal DNA to determine. Of 166 Salmonella isolates, 37 serotypes were …


Prevalence And Risk Factors For Canine Cognitive Dysfunction Syndrome In Thailand, Chutamas Benjanirut, Chanakarn Wongsangchan, Piyathip Setthawong, Wittanee Pradidtan, Suphanuch Daechawattanakul, Kris Angkanaporn Sep 2018

Prevalence And Risk Factors For Canine Cognitive Dysfunction Syndrome In Thailand, Chutamas Benjanirut, Chanakarn Wongsangchan, Piyathip Setthawong, Wittanee Pradidtan, Suphanuch Daechawattanakul, Kris Angkanaporn

The Thai Journal of Veterinary Medicine

Canine cognitive dysfunction syndrome (CDS) is a disease similar to Alzheimer’s in humans. This progressive neurodegenerative disease affects senior dogs, causes many behavioral changes and decreases welfare in both the dog and owner. Even with its high impact, many studies have shown CDS is underdiagnosed. The aims of this study were to investigate the prevalence of CDS in Thailand and to identify its risk factors. In this study, 622 senior dogs (seven years old and older) were randomly recruited. After an initial interview, 389 dogs were excluded from the study due to clinical and/or sensory impairment. Owners of the remaining …


Current Situation Of Neospora Caninum And Toxoplasma Gondii Infection Among Beef Cattle In Kanchanaburi, Ratchaburi And Nakhon Patom Provinces, Thailand, Ruenruetai Udonsom, Yaowalark Sukthana, Yoshifumi Nishikawa, Ragab M. Fereig, Charoonluk Jirapattharasate Sep 2018

The Thai Journal of Veterinary Medicine

Toxoplasmosis and neosporosis are parasitic diseases of livestock globally. In this study, we investigate the presence of Neospora caninum and Toxoplasma gondii in 250 beef cattle from Kanchanaburi, Ratchaburi and Nakhon Patom provinces, Thailand comparing with the results from 5 years earlier. The serological diagnosis for toxoplasmosis and neosporosis were performed by indirect ELISA technique using recombinant antigens TgGRA7 and NcSAG1, respectively. Furthermore, risk factors at the animal- and herd-levels were also evaluated. Seroprevalence of T. gondii, N. caninum and co-infections were 15.2%, 20.8% and 27.2%, respectively. In comparison to the results from 5 years earlier, seropositivity of N. caninum …

Comparison Of Gts And Rapd Assays To Characterize Thai Mycoplasma Gallisepticum Strains, Arithat Limsatanun, Jiroj Sasipreeyajan, Somsak Pakpinyo

The Thai Journal of Veterinary Medicine

Mycoplasma gallisepticum (MG) is one of the important pathogens which have economic impact on the poultry industry worldwide. Molecular characterization is the effective method to study the relation among international strains and the epidemiology of MG transmission. In this study, 17 Thai MG strains were characterized by using 2 molecular assays including random amplified polymorphic DNA (RAPD) and gene-targeted sequencing (GTS) assays. Results showed that the RAPD assay could classify the Thai MG strains into 3 patterns.Most MG strains obtained from the same area were in the same pattern. Partial mgc2 gene was used to distinguish between the Thai MG …
