Objective: The present study was aimed to ascertain the antimicrobial status of different solvent leaf extracts of Lantana camara leaves and its potential against the microbial strains by antimicrobial screening assay. 
Methods: The four different solvent plant leaf extracts were screened against ten pathogenic microorganisms for possible antimicrobial activities was performed by agar disc diffusion method in Mueller Hinton agar plates. 
Results: The results of this study revealed that, the most of the plant extracts exhibited antimicrobial properties. The highest potential was observed in the chloroform extract of Lantana camara against Escherichia coli, Staphylococcus aureus and Salmonella typhi. Whereas the petroleum ether and hydroalcoholic extracts show activity against S. aureus. Hydroalcoholic extract shows activity against S. typhi. Water extract does not show any activity against any bacterial strains. The hydroalcoholic extract also showed activity against Pseudomonas aeruginosa, Staphylococcus aureus. 
Conclusion: The experiment confirmed the efficacy of some selected plant extracts as natural antimicrobials and suggested for the possibility of employing them in drugs for the treatment of infectious diseases caused by the test organisms.
