  1. aOthers (one isolate each): Comamonas testosteroni, Pantoea agglomerans, and Rahnella aquatilis (ESBL expression); Aeromonas hydrophila, Cedecea davisae, Hafnia alvei, Leclercia adecarboxylata, Lelliottia amnigena, Serratia liquefaciens, and Yokenella regensburgei (no ESBL expression); Even though we found four isolates of Acinetobacter spp. from flies, the proportion of ESBL was not analyzed in this study. As described in (Fig. 1) above, the proportion of ESBL was near to similar in GNB isolated from clinical samples and flies caught in hospital compound. However, it was extremely low 1 (2%) in flies caught in butchery
