Isolation, Identification and Antibiotic Typing of Enterococcus Species Isolated from Coastal Waters in Eastern Regions in Guilan Province

Article excerpt

Background: Enterococci are important human pathogens which involved either in community or hospital infections and exhibit intrinsic resistance to various antibiotics. In re- cent years, enterococcal infections have become major thera- peutic challenge because of their increased incidence and spread of strains that have acquired resistance to several an- timicrobial agents. Presence of bacteria in swimming waters is one of the contamination resources.

Methods: This study performed during suitable swimming seasons in summer and autumn. One hundred samples which collected in 14 prefectures in eastern regions of Guilan prov- ince were analyzed for the presence of resistant Enterococci to the common antibiotics. Also, we measured the parameters including temperature, turbidity, dissolved oxygen, pH, salini- ty, and phosphate and nitrate contents of waters. Enumera- tion of bacteria was achieved by MPN method. After confir- mation of Enterococci species by biochemical and physiological tests, antibiotic susceptibility testing wasaccomplished by agar disk diffusion. …
