Immunohistochemical Detection Of Feline Viral Rhinotracheitis In A Cat, Nopadon Pirarat, Yumi Une, Yasuo Nomura
The Thai Journal of Veterinary Medicine
A female, 10-month old, mixed breed cat showed clinical signs of severe dehydration, purulent nasal discharge, dyspnea, severe crepitating lung sounds and no response to antibiotic treatment. Upon necropsy, histopathology revealed severe, diffuse, fibrinopurulent pleuropneumonia and numerous, homogeneous, amphophilic, intranuclear inclusion bodies in the pulmonary alveolar macrophages, bronchial and alveolar epithelium and bronchial glandular epitheliums. Immunohistochemical studies using 3 different monoclonal, anti-Feline Herpesvirus type 1 antibodies, revealed immunoreactivity of viral antigen in the lung that was associated with the histopathological changes. Monoclonal, anti-glycoprotein B, antibody showed the strongest immunoreactivity.

The Role Of Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) In The Porcine Respiratory Disease Complex (Prdc), Roongroje Thanawongnuwech
The Role Of Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) In The Porcine Respiratory Disease Complex (Prdc), Roongroje Thanawongnuwech
The Thai Journal of Veterinary Medicine
Concurrent bacterial infections of the respiratory tract in porcine reproductive and respiratory syndrome virus (PRRSV)-infected pigs is a major problem for the swine industry and may involve various factors. This review manuscript discusses the role of pulmonary macrophages, which are affected by PRRSV. The macrophage's phagocytic and bactericidal ability is altered by the PRRSV infection as is pulmonary clearance. PRRSV also induces apoptosis and macrophages cell lysis leading to an increased susceptibility to secondary bacterial infection, and the syndrome called porcine respiratory disease complex (PRDC). Prevention and control strategies for these concurrent infections are briefly discussed.

The Thai Journal of Veterinary Medicine
A six-year old bull (Bos indicus) was found to have hypospadia (congenital rupture of the ventral aspect of the penile urethra). The testes were a normal size and the penis slightly hypoplastic. Karyotype obtained from the conventional staining of chromosomes and GTG- and RBA- bandings revealed a normal make-up, of 60 XY male chromosomes. The levels of serum testoterone, estradiol and progesterone were all within the normal range. Based on the phenotypic abnormality and the karyotypic findings, this bull can be classified as a male, pseudohermaphrodite.

A Comparison Of Resazurin Test Scores On Milk, After 1 And 3 Hours And Comparing It With Total Bacteria, Coliform And Somatic Cell Counts, Sophat Chawalkul, Witaya Suriyasathaporn
The Thai Journal of Veterinary Medicine
The present study was conducted to compare results of a resazurin test on milk, scoring it after 1 hour and 3 hours and relating it to total bacterial count, coliform count and somatic cell counts. Milk samples from the bulk tanks of 337 dairy farms in Amphur Muang and Kumpangsan, Nakhon Pathom Province, were collected during October to December, 1998. Results from multiple regression analyses showed that the resazurin test scored 1 hour later was associated only with the total bacterial count (p < 0.05), but after 3 hours associations with total bacteria, coliform and somatic cell counts were seen (p < 0.05). We conclude that a resazurin test scored after 3 hours gave a better result than the test scored after 1 hour when judging total bacteria, coliform and somatic cell counts

The Thai Journal of Veterinary Medicine
Formalin fixed tissues from an aborted foal which had been diagnosed as having Equine Herpesvirus (EHV) infection, on histopathological criteria, were examined for EHV antigen using immunohistochemistry. EHV antigen was found in the focal necrotic area of the liver, especially in hepatocytes and Kupffer cells. Intranuclear and intracytoplasmic, immuno-positive labelings were also prominent in bronchiolar epithelial cells. The method allowed the visualization of the antigenic site distribution and their subsequent correlation with histopathological changes.

The Use Of Fresh, Salt-Stored And Frozen, Immature And Mature Oocytes, To Assess The Penetration Ability Of Porcine Spermatozoa, Adisorn Adirekthaworn, Mongkol Techakumphu, Sudson Sirivaidyapong, Saroch Gnamkum
The Thai Journal of Veterinary Medicine
The objective of this study was to compare the penetration rate of sperm, collected from two Landrace Boars A and B, into fresh, salt-stored and frozen, immature and matured oocytes. The first experiment, performed on immature oocytes, revealed that the penetration rates for the three groups of oocytes was from Boar A 59.6%(59/99), 78.1%(75/96) and 77.8%(77/99) (p<0.05) and the number of sperm penetration each oocyte was 2.79±0.42, 2.97±0.29 and 2.29±0.26 respectively (p>0.05). While for Boar B, the percentages were 65.3%(62/95), 76.8%(73/95) and 77.8%(77/99) with the number of sperm per oocyte being 2.25±0.28, 3.63±0.42 and 2.57±0.36. The highest values were found in the salt-stored group (p<0.05). The second experiment involved sperm penetration into in vitro mature oocytes. No differences were found for the sperm penetration rate and the number of sperm per oocyte using semen from Boar A which were 85.1%(74/87), 86.1%(56/65) and 89.1%(79/88) and 13.87±1.45, 17.69±2.61 and 14.45±1.75. While for Boar B, the lowest penetration rate was found when using fresh oocyte, lower than the two other groups; 52.6%(50/95), 67.3%(64/95) and 69.1%(67/ 97)(p<0.05). The number of sperm entering each oocyte was also inferior in the fresh oocytes than in salt-stored and frozen ones; 1.55±0.31, 2.80±0.35 and 2.87±0.40 (p<0.05) respectively. The conclusion that can be drawn from the experiment is that a) there are significant differences in the sperm penetration ability of different the boars used and b) the type of oocytes; immature vs. mature and fresh vs. salt-stored vs. frozen influenced the results that were obtained. It maybe possible to apply such an in vitro penetration assay to determine boar semen fertility under field conditions.

The Effect Of Methylparathion On Cholinesterase Activity In Cockle (Anadara Granosa L.) Muscle Tissues, Yanin Limpanon, Sukanya Phalitakul, Griangyut Tapcharoen, Janenuj Wongtavatchai, Piyarat Subhachalat
The Thai Journal of Veterinary Medicine
The effect of methylparathion on cholinesterase activity in foot muscle tissues of cockle were evaluated. Ninety - five healthy cockle were randomly divided into control and experimental groups. The experimental group was exposed to 10 ppb of methylparathion for 90 hours. Measurements of cholinesterase activity revealed increasing enzyme activity in foot muscle (p < 0.05) in the exposed animals while clinical observations showed no differences between the groups. The results indicate that methylparathion affects the observed activity of cholinesterase in cockle. However, it should be noted that the data do not correlate with those of previous studies reported in other aquatic animal species.
