This study was conducted to delineate potential sites of exit and duration of shedding of porcine reproductive and respiratory syndrome virus (PRRSV). Two experiments of 6 pigs each were conducted. Pigs were farrowed in isolation, weaned at 7 days of

Persistent infection with porcine reproductive and respiratory syndrome virus (PRRSV) was shown in experimentally infected pigs by isolation of virus from oropharyngeal samples for up to 157 days after challenge. Four 4 week old, conventional, PRRSV

Infection of porcine alveolar macrophages by the porcine reproductive and respiratory syndrome virus (PRRSV) was significantly enhanced in vitro by antibody raised against the PRRSV isolate ISU-P (p < 0.01). Increased yields and infection rates were

The susceptibility of swine to infection with encephalomyocarditis virus (EMCV) was assessed. Transmission of EMCV in a single exposure by gavage or intranasal routes was highly dose dependent. In a direct comparison, animals were exposed to EMCV by

The potential of a pseudorabies virus (PRV) nucleocapsid protein (NC)-based enzyme-linked immunosorbent assay (ELISA) as a screening assay for PRV infection in subunit-vaccinated and nonvaccinated pigs was studied. The NC-ELISA compared favorably to

A respiratory variant of transmissible gastroenteritis virus (TGEV), designated PRCV-Ind/89, was isolated from a swine breeding stock herd in Indiana. The virus was readily isolated from nasal swabs of pigs of different ages and induced cytopathology

Porcine reproductive and respiratory syndrome (PRRS) is a recently identified viral disease of swine that is a significant problem in swine producing regions throughout the world. Because of the potential economic impact of PRRS on swine production,

The differential pseudorabies virus (PRV) vaccines currently in use in the USA have deletions of the genes coding for the glycoprotein I (gl) and/or glycoprotein X (gpX). The absence of gI and/or gpX allow for the serologic differentiation of vaccina
