ABSTRACT:
Various microorganism causing infections are gaining resistance to antimicrobials for both community and hospital acquired infections. This has been one among the main reason for increased cost of therapy and long stay of hospitalizations now a days. The present study was carried out to identify the main microorganisms causing common communicable diseases and their sensitivity and resistance to antibiotics commonly prescribed. The study was carried out for a period of 1 year in Tiruvallur government hospital in both Inpatients and outpatient department. Cases of patient were collected from Microbiology department of the hospital, was tabulated and analyzed. Out of 500 samples selected for the study, 120 were found to be positive for culture sensitivity test. Common microorganism identified were Staphylococcus aureus (45), Escherichia coli (36). Lower respiratory tract infections (34) and urinary tract infections (35) were common among other infectious conditions. Highest resistance to gram negative organisms were found towards Levofloxcin, Norfloxacin, of loxacin (almost 100%) and gram positive organism was to Amikacin Cipro floxacin (100%). Methicillin resistant staphylococcus aureus infected diseases posed a difficulty in its treating conditions. The antimicrobial resistance to various organisms varies according to the geographical region of habitats and hospitalizations. A proper review on the sensitivity pattern along with the antimicrobial use in the patient helps in eradicating this condition to certain extent.
