An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of antibodies to influenza A/Hong Kong/1/68, influenza A/Victoria/3/75, influenza B/Hong Kong/5/72, and parainfluenza type 1 viruses. Development and standardization of the method indicated that an acetone-ethyl alcohol mixture was a suitable fixative for the preparation of the solid-phase coupled antigen. The addition...
After aerosolization of a bovine strain of parainfluenza type 3 virus, the pathogenesis of the virus was followed from the trachea to the bronchioalveolar compartments of the lung of colostrum-free calves and of conventionally reared calves during a 5- to 12-day postexposure interval. By tissue titration, plaque assay, and electron microscopy, it was found that virus infection could be establi...
Three acyl derivatives of amino acids, dicarbobenzoxy-l-lysine sodium, carbobenzoxy-l-aspartic acid-beta-benzyl ester potassium, and N-3-phenylpropionyl-S-benzyl-l-cysteine potassium inhibit the growth of parainfluenza 1 (hemadsorption 2) virus. The growth of simian virus 40, vaccinia, poliomyelitis type 1, Semliki Forest, Eastern equine encephalitis, and Western equine encephalitis viruses was...
respiratory disorders are major concern for dairy cattle industry. viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. the most important viral agents arebovine viral diarrhoea virus (bvdv), bovine herpes virus type 1 (bhv-1), bovine respiratory syncytial virus(brsv), parainfluenza virus type 3 (piv-3) and bovine adenovirus (bav). this cros...
This study was performed to investigate the etiologic agents, age distribution, clinical manifestations and seasonal occurrence of acute viral lower respiratory tract infections in children. We confirmed viral etiologies using nasopharyngeal aspirates in 237 patients of the ages of 15 years or younger who were hospitalized for acute lower respiratory tract infection (ALRI) from March 1996 to Fe...
