THE TOXICITY OF HEXANOLIC EXTRACT OF XYLOPIA AETHIOP]CA TO LABORATORY REARED LARVAE OF CX. P. QUIUEFASCIATUS.

Abstract

Crude extracts of Aloe Vera in ethanol and chloroform as well as its local products were tested for antimicrobial activity against eleven microbial clinical isolates. The isolates consisted of six bacteria and five fungi. The crude extracts were obtained by decoction. Agar cup diffusion method was the main susceptibility test while agar- dilution technique was employed in respect of the local liquid product. Staph. aureus, Staph. a/bus and
Sa/. paratyphi showed varying levels of growth inhibition by the ethanolic extract while the chloroform extract showed activity on Sa/. typhi and Sa/. paratyphi .Ofthe two local products of Aloe Vera, the Band B soap was
active on Staph. a/bus and Staph. aureus while the liquid product showed varying levels of activity on all the bacterial isolates as evident in the countable colonies relative to carpeted growth where there was no activity.
