Porcine pulmonary intravascular macrophages were isolated from six to eight week old pigs by perfusing the pulmonary vasculature with collagenase solution. The isolated cells were nonspecific esterase positive, phagocytic, ...

Bovine leukemia virus (BLV) was studied in naturally-infected cattle to clarify the cellular tropism of the virus at different stages of disease and obtain further evidence of a genetic basis for the development of ...

The food chain transfer of Polychlorinated Biphenyl (PCB) congeners was assessed in rat and human tissue after the consumption of contaminated Great Lakes fish. Fish from Lake Superior (LS), Lake Michigan (LM), and Lake ...

Inflammatory cytokines, interleukin 1 (IL-1$\alpha,$ IL-1$\beta$) and tumor necrosis factor (TNF-$\alpha),$ are coordinators of the immune and inflammatory responses but also play a critical regulatory role in brain ...

Pseudorabies (PrV) is an alphaherpesvirus disease of swine. The lungs are a main site of viral replication and alveolar macrophages (PAM) are productively infected. Programs for the eradication of PrV are currently underway ...

Current antimicrobial susceptibility testing methods do not assess the influence of host defenses, the dynamics of drug disposition, or the interaction between changing drug concentrations and a bacterium in a host ...

Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) is a 15Kb enveloped positive-sense, single stranded RNA virus. More than two decades after the emergence of PRRSV, much is known about the viral genome, spread, ...

Molecular diagnostic tests to detect ovine lentivirus (OLV) infected sheep were developed and validated and then applied to study the epidemiology and production impacts of natural OLV infection in flocks at the U.S. Meat ...

Rotaviruses are the most common agents of viral diarrhea in the young of many species, including piglets. A virus-host cell binding assay was developed and used to investigate specific binding between Group A porcine ...

Soluble Babesia bigemina antigens were prepared from short-term in vitro cultures utilizing a microaerophilous stationary phase culture system. In two pilot immunization experiments involving 6 cattle, 3 doses of 25 ...
