Most urinary tract infections are caused by Gram-negative bacteria (particularly E. coli) but a wide range of pathogens have been implicated.

Infective causes, such as Neisseria gonorrhoeae or Chlamydia trachomatis, are usually acquired during sexual contact and do not ascend to the bladder, so ...

The pathogenesis of uncomplicated urinary tract infection (UTI) is complex and influenced by many host biological and behavioural factors and by properties ...

UTIs. PATHOPHYSIOLOGY. The normal urinary tract is bacteriologically sterile, with the exception of the distal aspect of.

When UTI is severe and complicated, bacteria may enter the bloodstream (bacteremia) and potentially reach other organs or tissues, including the lymph nodes.

The urinary tract can potentially be infected by a very wide range of organisms, including viruses, bacteria, fungi and parasites.

Successful invasion of the urinary tract is determined in part by the virulence characteristics of the bacteria, the inoculum size, and the inadequacy of host ...

The bacteria associated with urinary tract infections can cause: - Chronic kidney infections (pyelonephritis). - Permanent renal damage.

UTIs can present clinically in a variety of ways, most often reflecting cystitis (infection of the bladder) or pyelonephritis (infection of the kidney).
