Ten otoscopes having a place with various specialists were tested by rubbing sterile soaked swab on the cones of otoscope, for bacteriological examination utilizing standard procedures. Out of ten otoscopes were analyzed, 9 (90%) were colonized with microscopic organisms. isolates incorporate Staphylococcus aureus 7 (70%), Staphylococcus epidermidis 1 (10%), Bacillus spp. 6 (60%), Pseudomonas aeruginosa 2 (20%) and Micrococcus spp. 1 (10%). Antimicrobial action of these bacterial segregates were additionally performed which uncover that all the Staphylococcus aureus detaches are methicillin resistant (MRSA). All the isolated bacteria show resistivity to surveyed anti-microbial with the exception of Ofloxacin. It is resulted from the study that otoscopes polluted with pathogenic microorganisms can go about as potential vector for the transmission of ear diseases. Along these lines, it is important to appropriately cleaned otoscope before inspect patient, to bring down the danger of transmission of disease.
