Comparative Analysis of Routine Laboratory Diagnostic Tests for Rabies

Abstract

Present study was undertaken to compare various routine laboratory diagnostic tests for rabies detection. Seller's staining, mouse inoculation test (MIT), Dot-ELISA, Agar gel precipitation test (AGPT) and counter immunoelectrophoresis test (CIET) were the main basic tests performed in the laboratory for the rabies diagnosis. Out of 200 brain specimens, Negri bodies were observed in 52 brain samples by Seller's staining. Rabies virus was isolated in 56 samples by intra-cerebral inoculation in newborn Swiss-albino mice. Dot-ELISA and AGPT could detect rabies antigen in 55 and 57 samples respectively. Comparative analysis revealed that the CIET is the most sensitive and rapid test among performed diagnostic tests.
