Characterization of Methicillin-resistant Staphylococcus aureus Isolated from Nearby Hospitals from two Different Countries

Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) is non-motile, facultatively anaerobic, gram-positive coccus non-sporulating bacterium. The MRSA was isolated as coagulase and catalase-positive, forming yellow-golden colonies on nutritive media as well as rosy to mauve colonies on CHROM-agar. MSRA is found in the mucus of the human, human skin, nasal cavity as an opportunistic pathogen and cause death in a person with a weak immune system and show resistant to the antibiotic methicillin. The MRSA is distributed greatly in clinics and hospitals, where it grows on surfaces of walls and benches. Staphylococcus bacteria are not restricted to animals and/or human beings but also found in the environment such as plant surfaces, and wastewater. S. aureus which shows resistance against methicillin is known to survive in the hospital environment for long periods and are found on the floor and walls of the building. However, before the present study, no reports have been found about the availability of MSRA in the soil. Finding of the present study would be critical as it would give a definite source that how MRSA was carried from the human to the environment of hospitals.
