Among these diseases, enteric infection are more prevalent and, virulent E. coli) are quite harmless and colonize the healthy human bowel, but recently developed strains are pathogenic causing frequently, cholecystitis, bacteremia, cholangitis, urinary tract infections (UTI), traveler's diarrhoea, neonatal meningitis, pneumonia, liver abscess and a few more. Antibiogram of 23 antibiotics revealed progressive increases of drug-resistance against each antibiotic with the maximum resistance values were recorded against gentamicin: 92% and 79%, oxacillin: 94% and 69%, ceftriaxone: 85% and 58%, and norfloxacin 97% and 69% resistance, in nosocomial and community isolates, respectively. Statistically, it was confirmed that ESBL strains were equally distributed in community or hospital units. A total of 395 (24.05%) ESBL strains were isolated from the total 810 isolates of community of the total of 464 (28.25%) isolates of wards and cabins, 199 (12.11%) were ESBL strains and among the total of 368 (22.41%) isolates of ICU and NICU, ESBLs were 170 (10.35%) the total nosocomial ESBL isolates, 369 (22.47%) were from the nosocomial total of 832 (50.66%) isolates. coli strains increased in a mathematical progression in community sources, but in nosocomial infections, such values remained almost constant in each quarter. Of the total 1642 (100%) isolates, 810 (49.33%) strains were from OPD and 832 (50.66%) were from hospital settings.
