Antibiotic Resistance in Isolated Negative Gram Bacteria From Intestinal Organ of Anzali Wetland Wild Common Carp

A research has been performed on antibiotic's resistance in negative gram bacteria separated of wild common carps intestinal organ. 126 negative Gram bacteria have been separated in total and resistance rate of bacteria in relation to 6 Antibiotics are measured: Ampicillin (10 microgram Am), Streptomycin (30 microgram S), Tetracycline (30 microgram T), Chloramphenicol (30 microgram C), Gentamycine (10 microgram GM), Amikacin (30 microgram AK). The results showed that negative Gram bacteria in comparison to antibiotic such as Ampicillin (93.5%), Streptomycin (51.15%), Tetracycline (46.5%) had higher resistance. So it showed that such bacteria’s resistance in comparison to Chloramphenicol (12.15%). is relatively low and it showed loss of existence of resistance in negative Gram bacteria in comparison to Gentamycine and Amikacin (0%). Surveying of the resistance rate of bacteria to some antibiotics show that 80% of separated bacteria from fish intestinal organ in comparison to consumption antibiotics are multi-resistance. Research shows that antibiotics consumption in animal is growing and more consumption of antibiotics in environment could cause bioenvironmental problems such as resistance against antibiotics. This research which was done for the first time in Anzali Wetland on Antibiotic resistance rate in negative Gram bacteria separated of wild common carp digestive system shows that negative gram system resistance against antibiotics in Anzali Wetland is high.
