Abstract

This study was conducted to determine the serological profile of Riceyellow mottle virus isolates collected from different locations in Niger State between 2010 and 2015. The Indirect Triple Antibody Sandwich Enzyme-Linked Immunosorbent Assay (TAS-ELISA) was used for profiling, and results indicated that the virus isolates belonged tosero groups 1 and 2 (S1 and S2). The isolates from Edozhigi and Gulu about 200 Km apart were characterized as S2; whereas isolates from Wuya and Edozhigi (barely 3 Km apart) were found to belong to S1and S2 respectively. The RYMV isolate from Wuya was recovered from a weed host, Echinochloa colona (L.) Link., which confirmed the weed as reservoir host of RYMV in the area. The present study has established the presence of two serotypes of RYMV in the same State of Niger in the North Central Nigeria.
