Genetically Modified Mosquitoes: A New Strategy To Control Mosquito Borne Diseases, Padet Siriyasatien, Usavadee Thavara
The Thai Journal of Veterinary Medicine
Mosquito borne diseases remain a major human and animal health concern in many areas of the world. Chemical control strategy faces a number of problems including the development of insecticide resistance in mosquitoes, the impact of insecticides on human and animal health and the environment and the constant inability to control mosquitoes effectively. Advances in the knowledge about mosquito-pathogen relationships and the molecular biology of mosquitoes make it now possible to produce mosquito strains that are unable to transmit various parasites or viruses. Strategies of using the genetically modified mosquitoes to control mosquito borne diseases are discussed here.

The Thai Journal of Veterinary Medicine
At least, 4 mosquito species, Culex tritaeniorhynchus, Culex gelidus, Anopheles vagus and Mansonia uniformis were identified on a pig farm in Nakorn Pathom, Thailand between March 2004 to February 2005. C. tritaeniorhynchus was found to be the predominant species (88.387.63%). To determine whether C. tritaeniorhynchus could serve as a mechanical vector for PRRSV transmission, 2 experiments were conducted on: the duration of PRRSV within the mosquitoes and PRRSV transmission from the PRRSV-infected pigs to naive pigs by the infected mosquitoes. PRRSV nucleic acid could be detected in the whole pooled mosquito samples for up to 48 hours post feeding in …

Rapid Isolation Of Dna From The Mucus Of Asian Arowana (Scleropages Formosus, Osteoglossidae), Nantarika Chansue
Rapid Isolation Of Dna From The Mucus Of Asian Arowana (Scleropages Formosus, Osteoglossidae), Nantarika Chansue
The Thai Journal of Veterinary Medicine
Owing to arowana being listed in CITES, DNA diagnostics should not rely on conventional methods of obtaining tissue samples. A non-invasive method of obtaining material containing DNA has been developed. Mucus samples for DNA isolation can be obtained by cotton swabbing the arowana body surface with subsequent purification of DNA fragments by using phenol/chloroform. DNA sample quality is assessed by UV absorbancy at wave lengths of 260 nm and 280 nm, as well as by calculating the absorbancy ratio involving 260 nm/280 nm results in order to determine DNA sample quality and quantity. Electrophoresis is employed to assess DNA quantity …

Nuclear transfer from adult somatic cells is an advanced reproductive biotechnology. This technique can be applied in animal production for producing a high genetically identical copy for endangered species conservation and for therapeutic cloning for human medicine. Our three-year preliminary study indicates the possibility of somatic cell cloning by using the rabbit as model of technical development. Later, interspecies cloning in wild cats and domestic cats was performed successfully in terms of cloned embryo production. Meanwhile, goat cloning served as the model for farm animals.

Florfenicol (FF) and Chloramphenicol (CAP) were tested for their in vitro antimicrobial activity against 102 Vibrio isolates from clinical cases. The Minimum Inhibitory Concentration (MIC) for both antimicrobials was ≤ 8 μg/ml suggesting that all of the tested isolates were susceptible to both antimicrobials. The observed MIC range of FF (0.5-4.0 μg/ml) was more potent than that of CAP (0.5-8.0 μg/ml). The activity of both antimicrobials was not substantially influenced by the addition of sea water (5 ppt salinity) to the test system. When considering the best type of antimicrobial for food producing animals and in vitro antivibrio activity, FF …

The Zoonotic Potential Of Enterocytozoon Bieneusi In Thailand, Mathirut Mungthin, Ittisak Subrungruang, Saovanee Leelayoova
The Thai Journal of Veterinary Medicine
Enterocytozoon bieneusi is the most common microsporidia that causes disease in immunocompromised hosts, especially in AIDS patients. E. bieneusi has been reported in a wide range of animals, including domestic, wild and farm animals. Using molecular typing and phylogenetic analysis, the zoonotic potential of E. bieneusi to cause disease is indeed a threat. Transmission from animals to humans should be investigated and whether it occurs naturally, before we can address the whole subject of zoonotic transmission of E. bieneusi infection.

Relationships Between The Immune System And Stress Reactivity In Pig: Visualizing The Immuno-Neuroendocrine Framework In Action, Sanipa Suradhat
The Thai Journal of Veterinary Medicine
Activation of the immune system is regulated through several mechanisms, within the system itself and by other body systems, in order to maintain disease resistance, and prevent immune-mediated disorders within the host. It is well accepted that the immunological, physiological, behavioral, and psychological state of an animal are closely linked and the factors affecting one feature of the network can influence the rest of the system.In recent years, our understanding of the interactions between the neuroendocrine network (i.e. the hypothalamicp tuitary- adrenal axis, HPA) and immune-mediated inflammatory reactions has expanded enormously. This article outlines the nature of the immuno-neuroendocrine network …
