Abstract
This study aimed to identify antibiotic-resistant Enterobacteriaceae in wastewater discharged into the landfill. 12 samples were collected from the stream point of tanker truck in The MINDOUBÉ municipal landfill to the river were carried out on 29 September 2022. Bacteriological assays performed at the IRET Microbiology Laboratory yielded one bacterial colony per sample once cultured and isolated. Their identification was as follows: Escherichia coli (58.3%), Serratia Ficaria/Pantoea spp (47.1%), Klebsiella oxytoca (33.3%) and Klebsiella pneumoniae (25%). Antibiotic susceptibility tests showed the presence of the following resistances: Ceftazidime and Cefepime (100%), Cefotaxime (54%), Amoxicillin and Clavulanic Acid (75%). Resistance to sulphonamides, quinolones and aminoglycosides was slight. Therefore, these wastewaters are the source of contamination of the neighbouring stream of the MINDOUBE landfill site. The promiscuity of this rubbish dump and the polluted river is thus having a deleterious effect on the health of the people living nearby, to the extent that they use the water from this river to meet their daily household needs. This suggests that the people living in this neighborhood and using the river water are regularly contaminated by multi-resistant bacteria. This could lead to therapeutic failures in managing infectious diseases triggered by these bacteria.
