Molecular Detection And Genotype Differentiation Of Feline Coronavirus Isolates From Clinical Specimens In Thailand, Somporn Techangamsuwan, Araya Radtanakatikanon, Suphasawatt Purnaveja

The Thai Journal of Veterinary Medicine

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% …

The Thai Journal of Veterinary Medicine

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 …


Seroprevalence Of Neospora Caninum In Swamp Buffaloes And Beef Cattle In The North-East Of Thailand, Hoai Nam Nguyen, Aran Chanlun, Kwankate Kanistanon, Suneerat Aiumlamai Jul 2012

Seroprevalence Of Neospora Caninum In Swamp Buffaloes And Beef Cattle In The North-East Of Thailand, Hoai Nam Nguyen, Aran Chanlun, Kwankate Kanistanon, Suneerat Aiumlamai

The Thai Journal of Veterinary Medicine

A seroepidemiological survey was carried out to investigate seroprevalence of Neospora caninum in swamp buffaloes from five provinces in north-eastern Thailand, and to compare infection status in swamp buffaloes and beef cattle at one area of Thailand. A single serum sample was collected from each of 532 swamp buffaloes and 78 beef cattle during January and July 2009. Antibodies against N. caninum were analyzed by a commercial ELISA test. Chisquare tests were used to compare the seroprevalence between species, gender and age groups in Khon Kaen. Result showed that infection prevalence in swamp buffaloes in northeastern Thailand was 4.5%. At …


Molecular Characterization And Detection Of Babesia Canis Vogeli In Asymptomatic Roaming Dogs In Chiang Mai, Thailand, Kittisak Buddhachat, Orachon Meesong, Korakot Nganvongpanit, Maslin Osathanunkul, Siriwadee Chomdej Jul 2012

Molecular Characterization And Detection Of Babesia Canis Vogeli In Asymptomatic Roaming Dogs In Chiang Mai, Thailand, Kittisak Buddhachat, Orachon Meesong, Korakot Nganvongpanit, Maslin Osathanunkul, Siriwadee Chomdej

The Thai Journal of Veterinary Medicine

The purpose of this study is to detect Babesia canis by using 18S rDNA amplification in order to confirm thepresence of the agents and to characterize molecularly the Thai B. canis. Three sets of primers, a Babesia canis-specificprimer (BcSP), Piroplasm-specific primer (PSP) and Babesia species-specific primer (BsSP), were tested for sensitivity.The results showed that BcSP and PSP were 50 times more sensitive than BsSP. Both BcSP and PSP were specificenough to detect this parasite in asymptomatic dogs. Peripheral blood samples were collected from 102 asymptomaticdogs residing in Chiang Mai and assayed with a light microscope and PCR by using BcSP …

Neospora Caninum And Toxoplasma Gondii Antibodies In Captive Elephants (Elephaus Maximus Indicus) In Kanchanaburi Province, Jitbanjong Wiengcharoen, Weerapan Nokkaew, Samart Prasithpon, Pornsak Prasomtong, Yaowalark Sukthana

The Thai Journal of Veterinary Medicine

Although neosporosis has long been detected in several wildlife species from different parts of the world,until now there has been no report of Neospora caninum infection in elephants in any country of the world. Serumsamples of 115 captive elephant (Elephas maximus indicus) from the westernmost province of Kanchanaburi, Thailandwere investigated for antibodies to N. caninum and Toxoplasma gondii. Antibodies of N. caninum were detected by thecompetitive ELISA (cELISA) test and T.gondii by the Latex agglutination (LAT) test. The prevalence of T. gondiiantibodies was 13.04% (15/115), while anti-N. caninum was 33.04% (38/115). Only 7/115 (6.09%) were positive forboth parasites. Our study …

Mosquito Distribution And Japanese Encephalitis Virus Infection In A Bat Cave And Its Surrounding Area In Lopburi Province, Central Thailand, Sonthaya Tiawsirisup, Alisa Junpee, Surang Nuchprayoon

The Thai Journal of Veterinary Medicine

Mosquito distribution and Japanese encephalitis virus (JEV) infection were studied in a bat cave and its surrounding area in Lopburi province, central Thailand. Mosquitoes were collected from May 2009 to April 2010 by using CO2-baited CDC-light traps, and dry ice as a source of CO2 to attract mosquitoes. Mosquitoes were identified and tested for JEV infection by using reverse transcription polymerase chain reaction (RT-PCR). Five genera of mosquitoes collected from the bat cave include Aedes, Anopheles, Armigeres, Culex and Uranotaenia, and eight genera of mosquitoes collected from the area close to the bat cave include Aedes, Aedeomyia, Anopheles, Armigeres, Coquillettidia, …

The Thai Journal of Veterinary Medicine

Bats are the reservoir hosts for several Paramyxoviruses including two serious zoonotic viruses, Hendra virus and Nipah virus which are responsible for fatal infections in animals and humans. These two viruses are sufficiently different from previously described Paramyxoviruses and are included in a new genus, Henipavirus. We report here a survey of cave-dwelling, insectivorous bats in Thailand for the presence of henipaviruses. Pooled urine samples were collected in nine caves inhabited by six different bat species in the northern (Chiangmai and Nakornsawan) and southern (Songkla and Satoon) provinces of Thailand. A reverse transcription PCR (RT-PCR) assay using henipavirus-specific primers derived …
