ABSTRACT
This study is designed to investigate the presence of diverse micro-organisms in the herbal
preparations made from green, unripe mature pawpaw fruits for the treatment of stomach
ulcer. Samples of pawpaw fruits were collected from a pawpaw plantation in Ibadan, Nigeria,
and used within one hour of being harvested. Pour plate method was employed for the
microbiological and biomedical charaterisation of isolates. The results confirmed the presence
of yeast and pathogenic organisms including bacteria and fungi. Among them are Alcalogenes
faecalis, M. kristianae, B. polymyxa, M. varians, Corynebacterium spp. as well as A.
iwoffi; which is the most pathogenic bacteria among the isolates, as the organism is known
to cause food spoilage and lower respiratory tract infection (LRTI) in humans. This herbal
preparation poses a potential hazard to human health if not consumed fresh. A suitable
means of preservation such as cold storage is therefore required if the preparation is to be
stored. In the alternative, the use of fresh preparations on a daily basis is highly recommended.
