This study is concerned with the biological testing of the resin extracts from Capsicum annuum var. longum(commonly known as siling haba in the Philippines), using the agar well method for conducting the microbial assay of the resin extractive against three different microorganisms, namely Escherichia coli for gram negative bacteria, Staphyloccus aureaus for gram positive bacteria, and Candida albicans for fungi with streptomycin used as positive control for bacteria and Nystatin as positive control for fungi
