ABSTRACT
The Profile of antibiotic resistant bacteria isolated from slaughterhouse effluents of Etoudi-Yaounde, and its receiving waterbody (River Ako’o) were investigated. Wastewater samples were collected from abattoir outlet and along the river (pond, mid river and out-river). Resistance to amoxicillin, tetracycline, ciprofloxacin, sulfamethoxazole / trimethoprim, cefixime and kanamycin were determined. Resistance to amoxicillin was the highest (96.3 %), followed by sulfamethoxazole / trimethoprim (85.1%), kanamycin (81.5 %), cefixime (81.3 %), tetracycline (80.9 %) and ciprofloxacin (73.6 %). Bacterial resistance was higher in October, compared to March and December. Higher resistance ratios were observed downstream at out-river (77.9 %). Enterobacteria constituted 80% of the isolates. Escherichia coli, Salmonella spp., Klebsiella spp., Shigella spp., Staphylococcus spp. and Streptococcus spp. were the identified drug resistant bacteria, Escherichia coli was more prevalent (30.7%). All isolates were multi-resistant antibiotic resistant bacteria and some presented resistance to third generation cephalosporin. Wastewater from Etoudi-abattoir is a serious vector of the spread of bacterial drug resistance, thus, strategies towards hygiene and sanitation of the slaughterhouse and its effluents should be implemented.
Key words: Antibiotic resistance, slaughterhouse wastewater, public health.
