Antibiotic Enteric Resistant Bacteria are Abundant on Lettuce from Urban Agriculture in the City of Yaounde

The presence of antibiotic resistant bacteria on lettuce from wastewater irrigated fileds in the town of Yaounde was investigated. Lettuce samples were collected from three agricultural fields located in three districts Ekounou, Ezazou and Nkolbisson , over a period of four months. Resistance to amoxicillin, tetracycline, ciprofloxacin, sulfamethoxazole trimethoprim and kanamycin were determined. Isolated bacteria presented highest resistance to amoxicillin 95.8 and lowest resistance to ciprofloxacin 89.2 . The resistance rate of bacteria was the highest in March 93.1 , and lowest in May 89.9 . Antibiotic resistant bacteria identified were belonged to the genus Salmonella, Bacillus, Staphylococcus, Shigella, klebsiella, Pseudomonas, citrobacter, Micrococcus, Enterococcus, Lactobacillus, Escherichia, and Streptococcus. Bacillus cereus was the most abundant 17.5 . The identified isolates were all multidrug resistant, except Lactobacillus which was only resistant to amoxicillin. The obtained results demonstrate the health risk posed by the cultivation and consumption of lettuce from urban agriculture in the city of Yaounde, which could constitute a strong vector for antibiotic resistance dissemination.
