Many small holder farmers in the south western agro-ecological zone (SWAEZ) of Uganda have for a very long time been using medicinal plants especially *Erythrina abyssinica* and *Capsicum annum* for the management of worms, Newcastle disease and other microbial infections respectively in local poultry (Nsubuga-Mutaka *et al*., 2005 and Lagu and Kayanja (2010). Commonly the root barks of *Erythrina abyssinica* are picked crushed and mixed with water and administered to the birds. The ripped fruits of *Capsicum annum* are picked crushed and mixed with solutions of ash and water (ITDG and IIRR) (1996); Lagu and Kayanja (2010). These medicinal combinations are mainly given to birds to treat them against worms and other microbial infections and worms (ITDG and IIRR, 1996). The farmers have been using these medicinal plant extracts for a very long time Katunguka-Rwakishaya *et al.,* 2004; Olila *et al.,* 2007; Ejobi *et al.,* (2007). It is however, not clear if the *Erythrina abyssinica and Capsicum annum* have activity against the common microbes that affect the poultry. This study aims to investigate the anti-microbial activities and minimum inhibitory concentrations (MICs) of *Erythrina abyssinica* and *Capsicum annum* used by the farmers in the control and treatment of common poultry infections in the south western
