During infection, pneumococci exist mainly in sessile biofilms rather than in planktonic form, except during sepsis.However, relatively little is known about how biofilms contribute to pneumococcal pathogenesis.Here, we carried out a biofilm assay on opaque and transparent variants of a clinical serotype 19F strain WCH159.After 4 days incubation, s
Most of the previous analyses of climate of Nigeria, particularly OndoState have been for agricultural use.They have little or no application for biometeorological purposes.This paper examines and analyse the climate of Ondo State, Nigeria with respect to biometeorological parameters based on air temperature, relative humidity, wind speed, final au
To evaluate transmission dynamics, we exposed 25 bird species to West Nile virus (WNV) by infectious mosquito bite.We monitored viremia titers, clinical outcome, WNV shedding (cloacal and oral), seroconversion, virus persistence in organs, and susceptibility to oral and contact transmission.Passeriform and charadriiform birds were more reservoir co
