Abstract
This study aimed to determine the pathogenicity of the bacteria isolated and characterized from the kpètè kpètè used to produce two fermented beers in Benin. Species were identified by specific biochemical tests such as catalase, coagulase, and API 20 E. Antibiotic sensitivity was tested according to the French Society of Microbiology Antibiogram Committee. The crystal violet microplate technique and conventional PCR evaluated biofilm production to identify genes encoding virulence and macrolide resistance. Our data shows that Kpètè Kpètè used to produce beers are contaminated by Enterobacteriaceae species (Klebsiella terrigena, Enterobacter aerogens, Providencia rettgeri, Chryseomonas luteola, Serratia rubidae, and Enterobacter cloacae) and Staphylococcus spp. These multidrug-resistant strains can produce biofilms with a strong predominance of Enterobacter aerogens, Klebsiella terrigena (100%), and Staphylococcus spp (60%). Enterobacter cloacae (4%) and Coagulase negative Staphylococcus (5.55%) harbor the macrolide resistance gene. For other strains, these genes were not detected. Foods contaminated with bacteria resistant to antibiotics and carrying a virulence gene could constitute a potential public health problem. There is a need to increase awareness campaigns on hygiene rules in preparing and selling these traditional beers.
