Antibiotic susceptibility of four Enterobacteriaceae strains (Enterobacter cloacae, Citrobacter freundii, Salmonella typhi and Shigella sonnei) isolated from wastewater, surface water and groundwater in the equatorial zone of Cameroon (Central Africa)

The health problems caused waterborne pathogens bacteria belonging to the Enterobacteriaceae family are aggravated by rise of antimicrobial resistant phenomenon. This has been identified as one biggest global challenges. present study aims make a comparative approach sensitivity/resistance antibiotics 4 Enterobacter cloacae, Citrobacter freundii, Salmonella typhi and Shigella sonnei isolated from wastewater, streams groundwater in Yaounde town (Cameroon, Central Africa). Bacteria were using standard methods their identification API 20E systems. antibiogram tests carried out Müller-Hinton antibiotic disc diffusion method. Results showed that inhibition diameters varied (P<0.05) with respect bacterial species on hand, type water harbored cells other hand. proportion strains each species, which sensitive or another within same family. For β-lactams tested, no E. cloacae strain sensitive. between 5.88% 23.53%. 2 aminoglycosides gentamycin. Of 3 quinolones all C. freundii fully Norfloxacin Ofloxacin. Sulfonamides+trimethoprim, S. Nurofurantoin Fosfomycin. Most wastewater surface tested. Many tested multi-resistant. multidrug resistance was more marked water. represents risk for humans aquatic environment.
