dc.description.abstractRabies is a viral zoonosis that causes encephalomyelitis. The rabies virus is a negative sense non-segmented RNA virus that codes for 5 proteins: N protein, P protein, M protein, G protein, and L protein. This research was aimed at carrying out molecular studies on a segment of N gene of rabies virus isolated from dogs in Benue State. The study revealed the presence of Nucleo protein antigen using the Direct Fluorescent Antibody Test (DFAT) in 2% of the 50 dog brain samples collected for the study. Sixty eight percent (68%) of the samples were from male dogs while 32% were from females. The 1 DFAT positive sample was from a male dog. The positive Sample (J50) with DFAT fluorescence score of (++++) was positive for Polymerase Chain Reaction (PCR) amplification of N-gene segment using N-gene specific forward primer; RabN-533F; 5‘-CATTGCAGATAGGATAGAGC-3‘ and reverse primer; RabN-888R; 5‘-GAGGAACGGCGGTCTCCTG-3‘ primer set. The amplified N gene segment of the isolate was sequenced and compared with 31 other rabies virus N gene sequences from the Gene bank. There was a maximum homology of 99% (KR080522 Dog from Bida 2012) and a minimum of 93% () . The group variation occurred at 32 different Non-serial positions of the nucleic acid of the gene, with a group variation rate of 8.3%. The phylogenic analysis gave an evolutionary pattern, showing the rabies virus is of West African origin belonging to the African 2 lineage and a possible history of Cameroonian origin considering that in an earlier year a similar rabies virus was isolated in that country and also might be associated with the fact that Benue state share border with the country.en_US
