Vector Potential of Blattella germanica (L.) (Dictyoptera: Blattidae) for Medically Important Bacteria at Food Handling Establishments in Jimma Town, Southwest Ethiopia

Cockroaches have been regarded as possible vectors of human enteropathogens. Their presence and crawl particularly in food handling establishments could be risky for human health. Therefore, this study was done to determine the vector potential of cockroach for medically important bacterial pathogen...

description Cockroaches have been regarded as possible vectors of human enteropathogens. Their presence and crawl particularly in food handling establishments could be risky for human health. Therefore, this study was done to determine the vector potential of cockroach for medically important bacterial pathogens in restaurants and cafeterias. A cross-sectional study was conducted on cockroaches from restaurants and cafeterias in Jimma town from May to September 2014. Standard taxonomic keys and microbiological techniques were applied for species identification and isolation. Data was analyzed in SPSS version 16.0. All cockroaches trapped were the German cockroach, Blattella germanica (L.) (Dictyoptera: Blattidae). Escherichia coli was the most frequently isolated followed by Salmonella species (serogroups B, D, E, C(1), and NG), Bacillus cereus, and Shigella flexneri. Wide varieties of bacteria of medical relevance were also identified. Of which, Klebsiella spp. 49(40.8%), Bacillus spp., and Staphylococcus saprophyticus were predominant. Blattella germanica (L.) (Dictyoptera: Blattidae) could serve as a potential vector for the dissemination of foodborne pathogens such as Salmonella spp., Shigella flexneri, E. coli, S. aureus, and B. cereus and these bacteria could be a major threat to public health. Therefore, environmental sanitation and standard hygiene need to be applied in the food handling establishments in that locality.
