A competitive enzyme-linked immunosorbent assay (C-ELISA) for the detection of antibodies against vesicular stomatitis virus New Jersey (VSV-NJ) and vesicular stomatitis virus Indiana (VSV-IN) was compared with the serum neutralization test (SNT) using 1,106 serum samples obtained from dairy cattle on sentinel study farms in the Poás region of Costa Rica. Kappa coefficients between the C-ELISA ...
In this study, a commercial DNA-DNA hybridization kit for the detection of Escherichia coli heat-stable enterotoxin is compared with a competitive enzyme-linked immunosorbent assay (ELISA) and the suckling mouse bioassay. Taking the suckling mouse assay as the "gold standard," the gene probe was the more specific and the ELISA was the more sensitive of the assays. The ELISA and the suckling mou...
We molecularly cloned the gag and env genes of the human immunodeficiency virus (HIV) and expressed fragments of these genes in Escherichia coli. Using the recombinant core and envelope proteins, we developed two competitive immunoassays (CIAs). Samples that recognized either the envelope or core proteins were considered positive for antibodies to HIV. This test system was comparable with weste...
background: this study is performed to reveal most common species and subspecies of leptospires that are main causes of human leptospirosis in guilan, northern province of iran. methods: we performed igm-elisa and mat on 282 blood samples from patients who attended to 3 hospitals in the flat area of guilan province with clinical symptoms consisted with leptospirosis. all specimens with titers...
Regarding harmful agents in livestock, parasites play an important role moreover it also effect 1/4th of the human populace by various zoonotic diseases (e.g. Toxplasma, Cryptosporidium, Trypanosomiasis, etc.). In livestock the parasites successful invade host immune responses, so early diagnosis of parasitic agents by various immunodiagnostic techniques is very important. Numerous immunologica...
