				Abstract 
 
				
				
				Aim: 
				
				Presently, diagnosis of rabies is primarily based on, 
				conventional fluorescent antibody technique (FAT), 
				immunopathological and molecular techniques. Recently, rapid 
				immunodiagnostic assay (RIDA) - A monoclonal antibodybased 
				technique has been introduced for rapid diagnosis of rabies. The 
				present investigation is envisaged to study the efficacy of RIDA 
				kit for the diagnosis of rabies in cattle. 
				
				
				Materials and Methods: 
				
				About 11 brain samples from cattle, clinically suspected for 
				rabies, were screened by the FAT, Heminested reverse 
				transcriptase polymerase chain reaction (HnRT-PCR), 
				Immunohistochemistry (IHC), and RIDA. 
				
				
				Results: 
				
				The sensitivity for detection of rabies from brain tissue by 
				RIDA was 85.7% as compared to 100% by IHC as well as HnRT-PCR. 
				The accuracy of detection of rabies by RIDA was 91.6% as 
				compared to 100% that of IHC and HnRT-PCR, whereas specificity 
				of RIDA was 100% like that of the IHC and HnRT-PCR. 
				
				
				Conclusion: 
				
				Despite a comparatively low-sensitivity and accuracy of RIDA, 
				latter can still be useful in screening a large number of field 
				samples promptly. However, it is recommended that negative 
				results with RIDA in cattle need to be authenticated by suitable 
				alternative diagnostic approaches. 
				
				Keywords: 
				
				cattle, diagnosis, fluorescent antibody technique, heminested 
				reverse transcriptase, immunohistochemistry, rabies.
