ABSTRACT
Urinary tract infections (UTI) are among the most common infections in humans. Although usually uncomplicated, they are often recurrent and cause considerable morbidity. About 40% of nosocomial infections are urinary in origin and these infections are a major cause of gram-negative bacteraemia and mortality. Both UTI and asymptomatic bacteriuria are common in elderly people (Table 1) and especially those in long-term care.
