The present study is conducted to establish the relationship between important plants of family Myrtaceae for their antimicrobial activity against human pathogenic bacteria. Leaves ofPsidium guajava (Guava), dried buds of Syzygium aromaticum (Clove), seeds ofSyzygium cumini (Jamun), leaves of Eucalyptus globulus and seeds of Callistemon viminalis (bottle brush) were extracted with methanol and the antimicrobial activity was tested against Escherichia coli, Staphylococcus aureus, Salmonella typhi, Klebsiellapneumoniae, Pseudomonas aeruginosa, Bacillus subtilis and Methicillin Resistant Staphylococcus aureus (MRSA). As compared to gentamycin (10 µg), all the plant extracts were found largely effective against all the tested pathogenic bacteria
