Development of latex agglutination test for rapid detection of antibodies against Bovine herpesvirus 1 and Bovine herpesvirus 5 in cattle.

A latex agglutination test (LAT) based on sensitized polystyrene beads with inactivated Bovine herpesvirus 1 (BHV-1) particles was developed to detect serum antibodies against BHV-1 and Bovine herpesvirus 5 (BHV-5). Compared with a virus neutralization test using 252 serum samples, the sensitivity and specificity were 94.7% and 97.

[Immunological screening of Toxoplasma tachyzoite cDNA expression libraries with serum from infected rats].

Objective: To screen and identify the potential candidates for the development of toxoplasmosis vaccine.

Methods: Rats were infected with Toxoplasma gondii (T. gondii) RH strain and their sera were used as a probe to screen T.
