ABSTRACT
The human pathogenic bacteria Pseudomonas aeruginosa is a gram negative pathogen, responsible for pneumonia, skin disease, Urinary Tract Infection. They are found in intestinal tract and blood of human beings and animals, which are known to be responsible for major health problems world wide. The test pathogen Pseudomonas aeruginosa was collected from the sputum of patient, cultured on Mac Conkey’s Agar Medium and identified by different colony characters and biochemical test. 50 % ethanolic extracts (v/v) of defferent available plant parts of 25 plants were screened for their antibacterial activity against test pathogens by ‘Inhibition Zone technique ‘ . The leaf extract of Heliotropium indicum Linn. was found to be the most active, forming the largest inhibition zone ( 30 m.m. ) in our experimentation., leaf extract of Tectona grandis Linn.,
