ACTIVIDAD ANTIBACTERIANA DE EXTRACTOS DE ANNONA DIVERSIFOLIA SAFFORD Y ANNONA PURPUREA MOCIÑO & SESSÉ EX DUNAL

Abstract

In the state of Chiapas Annona is represented by twelve species, the most common of
which are A. diversifolia (papausa) and A.
purpurea (chincuya). These are employed
by ethnic populations and farmers owing to
their antidiarrheal, anticold and anticough
properties and their ability to combat lice
and bedbugs. In this study the antibacterial
activity of crude extracts of both species
was evaluated on Escherichia coli (ATTC
25922), Salmonella Typhi (ATTC 6539) and
Klebsiella pneumoniae (ATTC 13883). The
extracts from A. purpurea were the most
active, and S. Typhi was the most susceptible bacterium followed by K. pneumoniae.
Extracts from stems of A. diversifolia and
A. purpurea did not exhibit an antimicrobial
effect on the tested bacteria.
