Poor knowledge about personal hygiene, lack of awareness about diet and unavailability of clean drinking water are major reasons of this infection. Varieties of infectious agents are responsible for UTI incidence but in present study E. coli and K. pneumonia were main causative agent of infection in majority of cases. This high prevalence of E. coli and Klebsiella in UTI patients is because of its resistance towards different antibiotics. These strains contains β-lactamases enzyme which provides resistance to β-lactam antibiotics. Prevalence and incidence of these bacteria is different in different region of the world. In present study bacterial resistance and susceptibility has been determined in UTI produced by E. coli and Klebsiella species against different antibioticsenUrinary track infectionβ-lactamasesMS ThesisThesis
