Prevalence and Antibiotics Susceptibility of Uropathogens in Patients from a Rural Environment, Tamilnadu (Report‪)‬

INTRODUCTION Urinary Tract Infections (UTIs) are one of the most common infectious diseases and nearly 10% of people will experience a UTI during their life time. (Delanghe et al., 2000; Hoberman and Wald, 1997) it is serious ailment in human due to the frequency, recurrence and difficulty in eradication UTI poses stiff challenge to the medical professionals. UTI is much more common in women than in men, due to anatomic and physiological reasons (Fihn, 2003). By virtue of its position urinogenital tract is more vulnerable to bacterial infections caused by both internal and external flora. It is not always possible to trace the mode of entry of bacteria into the urinary tract. Many authors have suggested four possibilities which are ascending infection, haematogenous spread and lymphogenous spread and direct extension from another organ. UTI with increased risk include infants, pregnant women and the elderly, as well as those with indwelling catheters, diabetes and underlying urologic abnormalities (Foxman and Brown, 2003). Incidence of uro-genital tract infection in hospital environment is on the rise due to cross infection and lowered immune status of the patients. Furthermore indiscriminate use of antibiotics has resulted in the emergence of drug resistant pathogens. Even though several different microorganisms can cause UTIs, including protozoan parasites, fungi and viruses, bacteria are the major causative organisms and are accountable for more than 95% of UTI cases (Bonadio et al., 2001).
