All the isolates were resistant against different antibiotics including the third generation cephalosporins. Resistance against ciprofloxacin, the frequently prescribed drug was 82%. Only meropenem and nitrofurantoin showed greater sensitivity towards the isolates showing 13 % and 33 % resistance respectively. The resistances were 90, 86, 82 , 79 , 78, 76, 75, 75, 74, 73, 72, 68, 33 and for amoxicillin, nalidixic acid, ciprofloxacin, cephalexin, ceftriaxone, cefixime, amoxiclav, ceftazidime, netilmicin, aztreonam, gentamicin, amikacin, nitrofurantoin and meropenem respectively. Thirtyone isolates were randomly selected for detection of ESBL Production by double disc diffusion synergy test. Twenty one isolates (67.74%) were positive in ESBL production. PCR experiments were carried out using the 21 ESBL positive <em>E. coli </em>isolates to examine the presence of two ESBL genes namely <em>bla</em><sub>SHV</sub> and <em>bla</em><sub>OXA</sub>. All (100%) of the 21 isolates showed the presence of <em>bla</em><sub>OXA</sub> gene, whereas 8 (38%) isolates among the 21 showed the presence of <em>bla</em><sub>SHV</sub> gene.</p><p>Bangladesh J Microbiol, Volume 30, Number 1-2,June-Dec 2013, pp 65-70</p> ER -
