Antimicrobial resistance pattern of citrobacter species isolated from food outbreaks

Foodborne diseases and resistance to antimicrobial agents are two of the world's most widespread global issues. Also, the excessive use of antibiotics has led to the resistance of bacteria belonging to the Enterobacteriaceae family to antibiotics, especially in carbapenems. Citrobacter is an opportunistic bacterium that is resistant to antibiotics in the emerging bacteria and has been challenging the treatment.
From 704 rectal swabs sent to the microbiological laboratory, 84 isolates of Citrobacter were isolated and identified using microbiological methods, differential tests and the API-20E kit. Antibiotic susceptibility was performed by disc diffusion method.
Of the 84 isolates of Citrobacter isolated from patients with diarrhea, the dominant species was Citrobacter Ferrandi. (42.9%), 36 isolates from men and (57.1%) were isolated from 48 isolates. The highest and lowest antibiotic susceptibility belonged to meropenem (100%) and ampicilin (57%) respectively.
Recently, antibiotic-resistant citrobacters have emerged in hospital infections. The results of this study indicate that monitoring of antimicrobial resistance in Citrobacter is necessary. The policy of using antibiotics should be developed in hospitals, so that effective antibiotics can be prescribed and administered uncontrolledly.
