Inactivation Of Picornaviruses And Caliciviruses Part 1: Biology And Epidemiology, Suphachai Nuanualsuwan, Dean O. Cliver Jun 2003

Inactivation Of Picornaviruses And Caliciviruses Part 1: Biology And Epidemiology, Suphachai Nuanualsuwan, Dean O. Cliver

The Thai Journal of Veterinary Medicine

Foodborne picornaviruses and human calicivirus have one molecule of linear, positive-sense, single-stranded RNA, covered by a capsid without a lipid envelope. These viruses have a spherical shape, a particle diameter of 27-40 nanometers and the triangulation (T=3) icosahedral symmetry of a capsid. The replication cycle of poliovirus (PV) and hepatitis A virus (HAV) occurs in the cytoplasm of the host cell. The viral proteins are synthesized by the translation of RNA after the virus particles attach and uncoat at the host cell membrane. Major translated proteins are structural protein (capsid protein) and functional proteins e.g. proteases and RNAdependent RNA polymerase. …

The Effects Of Weaning-To-Oestrus Interval On The Expression Of Oestrus And The Timing Of Ovulation In Sows, Nontakorn Urasopon, Wichai Tantasuparuk, Mongkol Techakumphu

The Thai Journal of Veterinary Medicine

The aim of the present study was to investigate the effects of the weaning-to-oestrus interval (WOI) and parity on the expression of oestrus and the timing of ovulation in crossbred (Large White x Landrace) sows. The detection of pro-oestrus and oestrus was performed every 8 hrs in all sows, by observing the reddening and swelling of the vulva and by applying the back pressure test in the presence of a boar. Ovulation was monitored every 8 hrs using transrectal ultrasonography. The duration of oestrus was 59.1, 59.8 and 65.3 hrs for parities 1, 2 and 3-4, respectively. Parity 1 and …

The Susceptibility Of Thai Native, Mixed Thai Native, Layertype And Broiler Chickens To Infectious Bursal Disease Virus, Thawat Lekdumrongsak, Jiroj Sasipreeyajan

The Thai Journal of Veterinary Medicine

Thai native, mixed Thai native and layer-type chickens, 50 birds of each and forty broiler chickens, were reared separately, to determine the susceptibility of each breed to infectious bursal disease virus (IBDV). All birds received IBDV when 36-days-old, given by oral inoculation. Mortality rates were observed for 10 days. Blood samples were collected on days 36, 39, 42 and 46 and sera were tested by an enzyme-linked immunosorbent assay (ELISA) for IBDV antibodies. Bursa to body weight ratios and histopathological lesion scores were determined when the birds were 36 and 46-days-old. The results revealed that mortality rate of Thai native, …

Dna Fingerprinting Of Leptospira Spp. Using A Repetitive Sequence-Based Polymerase Chain Reaction, Alongkorn Amonsin, Chailai Koowatananukul, Thanis Damrongwatanapokin, Somatat Wongsawang Mar 2003

Dna Fingerprinting Of Leptospira Spp. Using A Repetitive Sequence-Based Polymerase Chain Reaction, Alongkorn Amonsin, Chailai Koowatananukul, Thanis Damrongwatanapokin, Somatat Wongsawang

The Thai Journal of Veterinary Medicine

A DNA fingerprinting technique, repetitive sequence based polymerase chain reaction (rep-PCR), was used to characterize 20 isolates of both pathogenic and nonpathogenic Leptospira spp. Rep-PCR differentiated 20 Leptospira isolates into 16 rep-PCR patterns with a high index of discrimination (D=0.963). The results of cluster analysis demonstrated that pathogenic and nonpathogenic Leptospira belonged to separate clusters with at least 60% similarity. Overall, the results of our studies indicated that rep-PCR is useful for fingerprinting Leptospira species. The technique is simple, rapid, inexpensive and may be used for strain tracking in molecular epidemiological investigations of Leptospirosis outbreaks in the future.

It is considered that real time B-mode ultrasound is a useful tool for monitoring the ovulation …


Safety Evaluation Of Trichlorfon Used At A Therapeutic Dose Level For Ectoparasitic Treatment By Studying Serum Cholinesterase Activity Measurements In Carp (Cyprinus Carpio), Rangsiwan Pet-In, Rujira Thumma, Ubonrat Nimittritip, Janenuj Wongtavatchai, Piyarat Chansiripornchai Mar 2003

Safety Evaluation Of Trichlorfon Used At A Therapeutic Dose Level For Ectoparasitic Treatment By Studying Serum Cholinesterase Activity Measurements In Carp (Cyprinus Carpio), Rangsiwan Pet-In, Rujira Thumma, Ubonrat Nimittritip, Janenuj Wongtavatchai, Piyarat Chansiripornchai

The Thai Journal of Veterinary Medicine

The safety of trichlorfon at a therapeutic dose for ectoparasitic treatment in healthy carp (Cyprinus carpio) was evaluated by the measurement of serum cholinesterase (ChE) activity. Three groups of juvenile carp (70-80 g b.w., n =30 each) were bathed with 0.5 ppm trichlorfon 1, 2 or 3 times, respectively, at 5-day intervals. Serum ChE activity in each fish were compared pre and post-treatment. A significant post-treatment reduction of serum ChE activity (p < 0.05) was found in all groups, although they, resumed their pre-treatment levels 14 days after trichlorfon was withdrawn. All fish were clinically healthy throughout the experiment, suggesting, that the doses of trichlorfon applied in this study were safe.

The Thai Journal of Veterinary Medicine

The first commercial farm in Thailand to culture Abalone was studied to approve sanitation and food safety. Water quality and bacterial contamination criteria in both water from culturerelated sources and Abalone prior to marketing was examined. The water quality and bacteria found in the water samples (total aerobic plate, Vibrio count and MPN total coliforms) indicated the culturing practices adhere to the standards for shellfish sanitation. Total coliforms and other bacteria found in the Abalone samples also complied with microbiological guidelines for seafood products. The study details good farm manufacturing practices which can assure the food safety of Abalone. Further …

The Thai Journal of Veterinary Medicine

Serum copper (Cu) and zinc (Zn) concentrations in 5-35 thoroughbred foals and their dams during first 24 weeks after parturition were determined. Mean serum Cu in foals increased significantly (p < 0.01) with age, from 10.4±1.1 μmol/l at week 1 to 25.9±0.8 μmol/l at week 24, whereas those in mares decreased significantly p < 0.05, from 26.2±1.3 μmol/l at week 1 to 22.0±0.5 μmol/l at week 24 after parturition. There was a large negative correlation between the mean serum Cu concentrations in foals and their dams (r = -0.86, p < 0.01). Serum Zn concentrations in both foals and mares on the other hand, gradually decreased after parturition, ranging from and 17.7±0.3 μmol/l at week-1 to 13.8±0.5 μmol/l at week 24, in foals and from 16.2±1.2 μmol/l at week 1 to 14.4±0.5 μmol/l at week 24 in mares. The correlation coefficient between the mean serum Zn concentrations in foals and their mares was high (r = 0.895, p < 0.01).

The Thai Journal of Veterinary Medicine

Abalone are high cost seafoods regarded as delicacy. The decline of world abalone fishery has initiated the development of cultured abalone production in some countries. Thailand possesses geographical areas which are suitable for abalone habitats and the commercial abalone farming is currently promoted by the government. Commercial fishery for abalone in Thailand are presently unfamiliarity of their biology. This report describes the basis biology of abalone, development of abalone culture in tropical regions; selection and management of broodstock, in tank spawning, rearing of larvae through grow-out culture of advanced juveniles, to meet the requirement of consumers' seafood standard.


Seminal Plasma: Its Function And Importance For Pig Artificial Insemination, Kampon Kaeoket, Padet Tummaruk Dec 2002

Seminal Plasma: Its Function And Importance For Pig Artificial Insemination, Kampon Kaeoket, Padet Tummaruk

The Thai Journal of Veterinary Medicine

The objective of this review is to update information concerning the function of seminal plasma on the pig reproductive system, as well as its importance in artificial insemination (AI). It has been shown that seminal plasma advances ovulation in gilts by an average time of 10-14 hours, improves sperm motility, sustaines sperm viability during uterine transport, suppresses immune activities (chemotaxis of neutrophils), improved sperm transport, improves fertilisation rate, improves litter size in gilts and indirectly enhances fertility. The hormone estrogen, within the seminal plasma, causes a release of prostaglandins from the pigs endometrium to the utero-ovarian veins and lymphatic vessels. …
