Isolation and Antibiotic Susceptibility of Aeromonas Spp. from Drinking Water in Al-Khums Libya

Abstract

Background: Aeromonads are frequently found in drinking water and various types of foods. A relationship between the prevalence of different human diseases and the presence of antimicrobial-resistant Aeromonas has been reported (1). Aims: This study aimed to determine the prevalence and investigate the antibacterial susceptibility profiles of Aeromonas species in wells, reservoirs, and bottled drinking water in Al-Khoums City, Libya. Methods: Samples of drinking water obtained from deferent water sources in AL-khoums were examined for the presence of Aeromonas and its antibacterial susceptibility using standard microbiological procedures and the BD Phoenix Automated Microbiology System (PAMS, MSBD Biosciences, Sparks, MD, USA), according to the manufacturer instructions. Results: Of 147 water samples examined, 9 (6.12%) were positive for Aeromonas spp. these species were isolated from 6.38% (6/94) and 6.97% (3/43) of well water and water reservoir samples, respectively. Of the isolated Aeromonas spp., 100% were resistant to ampicillin and amoxicillin-clavulanate,77.8% were resistant to Cefoxitin, while all (100%) were susceptible to other antibiotics such as Amikacin, Meropenem. Conclusion: Potentially pathogenic antibiotic-resistant Aeromonas spp. are found in some drinking water sources in Al-khums.
