Bovine parainfluenza virus type 3 (BPIV3) is associated with upper respiratory disease in cattle in many countries. Here, we report the complete genome sequences of the BPIV3 BN-1 strain, isolated from cattle in Japan, and the BN-CE vaccine strain, derived from the BN-1 strain by passages in chicken embryo fibroblasts.

Diagnosis of respiratory virus infections currently involves detection by isolation or antigen detection, which usually identifies only a single suspected agent. To permit identification of more than one respiratory virus in clinical specimens, a rapid detection method involving a single-step, multiplex reverse transcription-PCR (RT-PCR) assay was developed. The assay included five primer sets ...

1. The effect of viral infection on the function of neuronal M2 muscarinic autoreceptors in the lungs was studied in anaesthetized guinea-pigs. 2. Guinea-pigs were inoculated intranasally with either parainfluenza type 3 or with a vehicle control. Four days later the animals were anaesthetized, paralysed and artificially ventilated. Pulmonary inflation pressure, tidal volume, blood pressure, an...

A quantitative, reproducible method was developed for the evaluation of the virucidal activity of test gases. Using this method, we determined the virucidal effectiveness of a Steri-Vac ethylene oxide gas sterilizer. Wool gabardine material was exposed to high concentrations of herpes simplex, vaccinia, parainfluenza, or polio viruses and was processed through the sterilizer. Two time-temperatu...

Heparin inhibited hemagglutination (HA) by equine arteritis virus (EAV) as well as did HA by Aujeszky's disease virus (ADV), but failed to inhibit HA by parainfluenza virus type 3 (PIV-3). The minimal concentration of heparin required to inhibit 8 HA U of EAV was 0.1 U/ml. In addition, most EAV hemagglutinin was retained by heparin acrylic beads, as was ADV hemagglutinin, but was not PIV-3 hema...

Simultaneous infection of canine distemper virus and canine parvovirus associated with distemper myocardial degeneration and necrosis is described in a pup. The dog demonstrated myoclonus, nystagmus, enamel hypoplasia, abdominal pustules, and bilateral corneal ulceration clinically. Demyelinating encephalitis, myocardial degeneration and necrosis with mineralization, and necrosis, hemorrhage an...

BACKGROUND Acute respiratory infection (ARI) is a major killer of children in developing countries. Although the frequency of ARI is similar in both developed and developing countries, mortality due to ARI is 10-50 times higher in developing countries. Viruses are common causes of ARI among such children, yet the disease burden of these infections in rural communities is unknown. METHODOLOGY/...

Nosocomial viral infections have not been well studied. In this context, the aim of this work is to review epidemiological and therapeutic data published on the main viral agents that can produce nosocomial respiratory infection. The study thus aims to expand knowledge of behaviour of these agents in nosocomial infections and provide information to improve the implementation of preventive measu...
