The pathogen Campylobacter fetus comprises two subspecies, C. fetus subsp. fetus and C. fetus subsp. venerealis. Although these taxa are highly related on the genome level, they are adapted to distinct hosts and tissues. C. fetus subsp. fetus infects a diversity of hosts, including humans, and colonizes the gastrointestinal tract. In contrast, C. fetus subsp. venerealis is largely restricted to...
A monoclonal antibody (MAb)-based antigen capture enzyme-linked immunosorbent assay (ELISA) was compared with the routine culture methodology for the detection of Campylobacter fetus subspecies from bovine and ovine field samples inoculated into Clark's transport enrichment medium (TEM). The work was a collaboration between two different diagnostic laboratories, one in Canada and the other in E...
This study reports on the use of PCR to directly detect and distinguish Campylobacter species in bovine feces without enrichment. Inhibitors present in feces are a major obstacle to using PCR to detect microorganisms. The QIAamp DNA stool minikit was found to be an efficacious extraction method, as determined by the positive amplification of internal control DNA added to bovine feces before ext...
Infectious bovine rhinotracheitis is an important disease of cattle with serious economic implications. The etiology is bovine herpes virus type-1 which leads to clinical to latent infections and abortions. In this study, an aborted bovine fetus was suspected of IBR infection. The virus was grown in cell line (MDBK) and cytopathic effect observed. CPE began at 12 hr post infection of cells and ...
In Argentina Bovine Genital Campylobacteriosis is routinely diagnosed by direct immunofluorescence test. Generally, the hyperimmune sera used for this test are obtained from rabbits and less often from goats. In this work, a chicken egg yolk immunoglobulin (IgY) extract was conjugated and its ability to detect campylobacters with the regular conjugate prepared with rabbit sera was comparatively...
