The Thai Journal of Veterinary Medicine

We studied the prevalence of swine salmonellosis and PFGE genotype of isolates in Gunma Prefecture,Japan. Between 2005 and 2008, swine salmonellosis was confirmed in 430 of 2,707,402 (0.02%) swine atslaughterhouses. All isolates were identified as deriving from Salmonella Choleraesuis, biotype Choleraesuis (negativefor H2S production). We used 30 bacterial strains from 15 farms that had experienced outbreaks in 2006 and 2007. Allstrains were susceptible to various antibiotics such as cephems (cefotaxime), fluoroquinolones (norfloxacin andciprofloxacin), and fosfomycin. On the other hand, all strains were resistant to tetracycline (TC), and 29 of 30 (97%)strains were resistant to streptomycin (SM). The most predominant profiles …


Hyaluronan And Syndecan-1 Localization In The Swamp Buffalo Oviduct, Paisan Tienthai Sep 2011

Hyaluronan And Syndecan-1 Localization In The Swamp Buffalo Oviduct, Paisan Tienthai

The Thai Journal of Veterinary Medicine

The glycosaminoglycans (GAGs) found in the mammalian oviductal tissue and luminal secretory fluidinfluence the fertilization processes in various patterns such as sperm storage, viability and capacitation. The aim ofthis study was to confirm the appearance of hyaluronan and syndecan-1 in the swamp buffalo oviduct consisting ofuterotubal junction (UTJ), isthmus, ampulla and infundibulum during oestrous cycle using histochemical andimmunohistochemical techniques. The non-sulphated GAGs, i.e. hyaluronan (HA), were noticeably localized in thesubepithelial connective tissue layer or lamina propria of all segments while the epithelial HA-positive staining wasdemonstrated only in the UTJ and isthmus (sperm reservoir) at the follicular phase. In contrast, the …

The Thai Journal of Veterinary Medicine

Virus infection requires the interaction of a virus protein with the host-cell receptor. The Influenza A virusreceptor consists of sialic acid linked to the galactose unit in a α 2,3 or α 2,6 conformation. Various types of thesereceptors are expressed differently on the epithelial lining of various animal species. Here we characterized the typesof receptors that are expressed in the upper and lower respiratory tracts of cow, buffalo, pig and quail. Our findingsdemonstrate that SA α 2,6-gal linked receptors for human influenza viruses are present in the lower respiratory tractof cow and buffalo, while the SA α 2,3-gal linked receptors …

Genes Associated With Genetic Diseases In Collies, Shetland Sheepdogs And Border Collies, Gunnaporn Suriyaphol Jul 2011

Genes Associated With Genetic Diseases In Collies, Shetland Sheepdogs And Border Collies, Gunnaporn Suriyaphol

The Thai Journal of Veterinary Medicine

Canine genetic disorders inherited through genes or chromosomes. Mutations can also occur spontaneouslyor influenced by environmental factors. Such disorders can be transmitted to offspring. However, the disease may notbe developed owing to other influenced factors. Dominant and recessive genetic mechanisms also affect the traitoutcome. This article discussed the abnormalities of genes affected by the disease and/ or genetic disorders in Collies,Shetland sheepdogs and Border collies, sharing the Collie lineage. Most of these disorders are caused by autosomalrecessive genes. Hence, paired recessive alleles are required in order to express its phenotype. Although dogs areasymptomatic carriers, they can pass down defective genes …

The Thai Journal of Veterinary Medicine

Porcine circovirus type 2 (PCV2) was first recognized as a causative agent of post weaning multisystemicsyndrome or PMWS in Canada in 1991. Subsequently, it has been reported in almost all intensive pig productioncountries, and currently all associated diseases linked to PCV2 are included under the term porcine circovirusassociated diseases or PCVAD. PCV2 can be divided into 2 major genotypes referred to genotype 1 (PCV2b) andgenotype 2 (PCV2a). In Thailand, PMWS was first reported in 1998. However, only one isolate of Thai PCV2 from ourgroup has been submitted to GenBank (AY864814). Therefore, the objective of this study was to determine thegenetic …

Prevalence Of Mycoplasma Wenyonii Infection On Seven Dairy Farms In Shanghai, China, Yuan Congli, Ying Hong, Zhang Zhonghai, Yang Zhibiao, Cui Li, Zhu Jianguo, Hua Xiuguo

The Thai Journal of Veterinary Medicine

Mycoplasma wenyonii (M. Wenyonii) was studied by PCR and blood smear staining in 197 cows. Clinical signsand hematological parameters of all tested cows were collected. Results confirmed that 31% populations werepositive of M. wenyonii infection. Statistical analysis revealed that the cows of 2-4 years old were most susceptible. Noclinical sings were found to be significantly associated with the infection. The infection also did not result in anemiabased on hematological investigation that only showed elevation of WBC counts in infected cows. Sequence analysisof the partial 16S rRNA gene showed that three different representative strains were confirmed in the present study.

The Thai Journal of Veterinary Medicine

The study is of the antinociceptive effects of tramadol on the thermal threshold response in eight cats using athermal threshold-testing device which contained a heater element and a temperature sensor placed on the shavedlateral thoracic area. Each cat randomly received an intramuscular administration of tramadol 2 mg/kg, morphine 0.2mg/kg and saline 0.04 ml/kg (placebo) at a weekly interval from an observer unaware of the treatment. The thermalthresholds were measured and recorded by activation of the heater until the cat showed a positive response (e.g. skinflicks, turning and looking at the probe and jumping forwards). Three baseline measurements were made at …
