Some of the fruits and vegetables that are used in our daily life have proved to be effective in treating the microbial and fungal infections. The current work was done to identify the anti microbial capacity of selected fruit extracts so as to design a more simple and economic means to treat these infections. The selected fruit samples were collected and various extracts such as Water, Ethanol, Chloroform and Methanol samples were made whose efficacy was tested against the selected bacteria Staphylococcus, Edwerdilla, Bacillus and Pseudomonas which are responsible for causing diseases like skin infections, typhoid, throat infections and allergies. The study proved that the samples of Pomegranate peel, Apple peel, Pomegranate seed crude and Tomato peel extracts had inhibitory effect against the test bacteria. This study can be further extended to test the range of organisms against which the samples have the inhibitory property. This effect can be implemented in developing food based therapies in treating infections.
