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, ...

African swine fever (ASF) is an acute viral hemorrhagic disease of domestic swine with mortality rates approaching 100%. Devastating ASF outbreaks and continuing epidemics starting in the Caucasus region, and now in the ...

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 ...

Orf or contagious ecthyma is a ubiquitous disease of sheep and goats caused by the parapoxvirus (PPV) orf virus (ORFV). The disease is characterized by focal lesions in the mucocutaneous transitions of the mouth that ...

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 ...

Competence induction in Streptococcus pneumoniae (pneumococcus) is initiated by the binding of the 17-amino acid competence stimulating peptide (CSP) to its membrane-associated histidine sensor kinase ComD. ComD ...

Porcine reproductive and respiratory syndrome virus (PRRSV) suppresses innate immunity, namely, type I interferons (IFNs-α/β) during infection and predisposes infected hosts to secondary bacterial infections. PRRSV also ...

Toxoplasma gondii (T. gondii) is an obligate intracellular apicomplexan protozoan parasite that infects about one-third of the world population, with estimated medical costs and loss of productivity in the USA alone amounting ...

Macrophages derived in vitro from bone marrow progenitor cells (BMDM) under the influence of CSF-1 or GM-CSF were compared for immune function. CSF-1- and GM-CSF-derived BMDM did not differ in their ability to kill L929 ...

The ALS gene family encodes large cell-surface glycoproteins associated with C. albicans pathogenesis. Als proteins are thought to act as adhesin molecules binding to host tissues. Wide variation in expression levels among ...
