The foot infection is the most consequence of diabetes mellitus, which greatly increases the risk of lower limb amputation. Effective antibiotic therapy is crucial in the treatment of these illnesses. The gram-negative bacterial samples from individuals with diabetic foot infections are evaluated in this study for their pattern of antibiotic susceptibility. Eighty-foot ulcer patients in total were collected, and 115-gram negative bacteria were taken, identified, and confirmed for antibiotic sensitivity using several drugs from various families. Finally, the phenotypic detection of extended spectrum beta lactamase, AMPC, and metallo-beta-lactamase MBL was performed. The results found different types of gram-negative bacteria isolated which are E. coli, Pseudomonas spp., Klebsiella spp., and Proteus spp. Also, the results show the different percentages of resistance of these bacterial isolates to different types of antibiotics and also their different percentage in their sensitivity to different antibiotics. This research revealed that 50% of diabetic foot infections were caused by several microbes. The most often found gram-negative-bacteria were E coli, Pseudomonas spp., Klebsiella spp., and Proteus spp. These bacteria were recovered from the taken cases. on the other hand, our study found a noted percentage of different isolated gram-negative bacteria for producing three types of beta-lactamase enzymes.
