Evaluation of environmental microorganism’s anti-bioresistance from sewage collectors from Abobo to Vridi, in the District of Abidjan, Côte d’Ivoire

Abstract

Objectives: The spread of bacterial resistance to antibiotics in the environment remains a major public health problem. Health centers, effluent treatment plants, livestock farms, households and collection centers are considered platforms for the transit and exchange of multi-resistant bacteria. Methods: This study was conducted to evaluate the level of antibiotic resistance of microorganisms in the environment. It consisted in collecting samples of wastewater from evacuation and sanitation channels in the city of Abidjan. A total of 99 samples of 2970 mL of wastewater were collected and standard microbiology methods were implemented. Results: At the end of the analysis, 215 coliforms of faecal or non-faecal, aquatic and telluric origin were identified. These microorganisms showed 55.81% resistance to β-lactams, mainly to amoxicillin, 7.67% to aminoglycosides, 6.05% to tetracycline and 3.49% to quinolones. Conclusion: Environmental bacterial strains are more and more resistant to the usual antibiotics.
