摘要

<span style="font-family:;" "=""><span style="font-family:Verdana;">Antimicrobial resistance refers to the ability of microorganisms to grow in the presence of an antimicrobial agent at a concentration that will normally kill or inhibit their growth. Antimicrobial resistance has become a major global threat making treatment of infections tougher especially with high cost of treatment in humans and animals. This study was done to determine the Multiple Antibiotic Resistant Index (MARI) of Gram-negative bacteria from bird droppings in two commercial poultries in Enugu. Forty (40) samples were collected from each of the poultries. Isolates were identified by standard microbiological methods. The isolates identified were </span><i><span style="font-family:Verdana;">Escherichia</span></i> <i><span style="font-family:Verdana;">coli</span></i><span style="font-family:Verdana;">, </span><i><span style="font-family:Verdana;">Klebsiella</span></i> <i><span style="font-family:Verdana;">pneumoniae</span></i><span style="font-family:Verdana;">, </span><i><span style="font-family:Verdana;">Pseudomonas</span></i> <i><span style="font-family:Verdana;">aeruginosa</span></i><span style="font-family:Verdana;">, </span><i><span style="font-family:Verdana;">Citrobacter</span></i><span style="font-family:Verdana;"> spp, </span><i><span style="font-family:Verdana;">Proteus</span></i><span style="font-family:Verdana;"> spp. and, </span><i><span style="font-family:Verdana;">Enterobacter</span></i><span style="font-family:Verdana;"> spp. Antibiotic susceptibility testing was carried out using disc diffusion technique. The organisms were tested against pefloxacin, augmentin (amoxicillin and clavulanic acid), ceftazidime, streptomycin, ciprofloxacin, gentamycin, cephalothin, neomycin and ofloxacin. The result of the susceptibility test showed that </span><i><span style="font-family:Verdana;">Proteus</span></i><span style="font-family:Verdana;"> spp had the highest resistance and MARI value of 0.5 and</span></span><span style="font-family:;"
