Polymerase Chain Reaction (PCR) merupakan uji diagnostik yang sangat sensitif. Enzim Taq salah satu komponen paling penting dalam pengujian (PCR). taq polymerase harganya mahal. Penggunaan pada PCR kurang efisien. Untuk mengetahui efisiensi penggunaan enzim dan volume terkecil berapa masih dapat digunakan metode PCR, maka dilakukanlah penelitian dengan membuat lebih kecil (5µl, 10 µl, 25 µl) da...
A dairy goat operation in Minnesota experienced a sudden, markedly increased mortality among its neonatal goats. Approximately 60 of 130 kids (46%) died. The animals had diarrhea and dyspnea of 1-2 days duration before death. Necropsy of 4 goat kids revealed marked, acute, catarrhal enteritis and fibrinous pleuropneumonia.

OBJECTIVE Bombyx mori parvo-like virus is a type of virus containing two single-stranded linear DNA molecules (VD1, VD2). In the present work, the structural proteins of B. mori parvo-like virus (China Zhenjiang isolate) (BmDNV-Z) were identified. METHODS The virions were purified by cesium chloride density gradient centrifugation from the feces of B. mori larvae infected with BmDNV-Z and ana...
It is estimated that approximately 60% of disease losses in shrimp aquaculture have been caused by viral pathogens and 20% by bacterial pathogens. By comparison, losses to fungi and parasites have been relatively small. For bacterial pathogens, Vibrio species are the most important while for viral pathogens importance has changed since 2003 when domesticated and genetically selected stocks of t...
