Antimicrobial resistance of Escherichia coli found in intestinal tract of Oreochromis niloticus

Abstract: Antimicrobial resistance (AMR) is an emerging public health problem worldwide. Agricultural practices have been suggested as one of the main contributors to the emergence and transmission of AMR worldwide. Aquatic animals like fish have an important role to play in the emergence and transmission of AMR strains. Escherichia coli is commensal in gastrointestinal tracts of many animals including fish, and is an indicator organism and opportunistic pathogen. It has been listed as one of the important bacteria invo… Show more

“…However, slightly lower levels of resistance of E. coli to tetracycline (18.2%), chloramphenicol (10%) and ampicillin (15%) were reported in that study. The highest resistance observed for erythromycin among antibiotics tested was consistent with that recorded in E. coli isolated from farm-raised tilapia in Bangladesh (81.25%) and Africa (72.7%) [25,26]. Sensitivity to ciprofloxacin and gentamycin was reported in an African study [25], as in this study.…”

Sensitivity to ciprofloxacin and gentamycin was reported in an African study [25], as in this study. In contrast, studies from India (ciprofloxacin; 60.5%) [22] and Vietnam (ciprofloxacin; 78.6% and gentamycin; 88.3%) [27] documented higher levels of resistance to the aforementioned antibiotics.…”

“…and MDR are increasing and developing countries are the worse affected; since they provide conditions and practices that support the development and spread of resistant microbes.Two theories have been advanced to explain the emergence of resistance in t bacteria contaminating water from human or livestock sources; or antibiotic residues escaping into the water exposing the resident bacteria to low levels of antimicrobial agents overtime [36]. Transfer of antimicrobial resistant bacteria to wild water due to sewage contamination has been reported in Australia [36,37]. The resisted antibiotics are those commonly used for treatment of various ailments in humans, thus strongly supporting the theories of introduction into the aquatic ecosystems from human associated sources.…”
