Table 1. Effect of E. cloacae on P. falciparum ookinete development in the mosquito.

An. stephensi females were fed P. falciparum gametocyte cultures mixed with medium alone (control) or with E. cloacae at the indicated concentrations. Individual midguts were dissected 20 h later and the number of ookinetes per gut was determined. Each value is the mean number of P. falciparum ookinetes (±SD) obtained from five midguts (n = 5) under each experimental condition. Each experiment was individually analyzed using a One-way ANOVA with a Dunnett’s post-test to determine the effects of E. cloacae on P. falciparum ookinete development. Asterisks denote significant differences with a P value of <0.05.
