UTI and Bacteria in Urine

UTIs (urinary tract infections) are the aliments or infections of our excretory system. In these infections, kidneys, ureters, bladder that stores urine and urethra (opening through which urine is sent out of the body) are affected, usually because of bacterial invasion. Sometimes this may also result as a disease that already has taken over the body.

All the organs of excretory system are highly sensitive entities. Any minor or major kind of disturbance can affect them adversely. For example white blood cells in urine(details) or high Urobilinogen in urine(details). Kidneys, in particular, are the most sensitive ones, affected most often by body’s changing internal environment like any fluctuations in blood pressure or blood sugar levels.

UTIs are found both in adults and children. In children, they might take serious turns because the children’s excretory system is more delicate than the ones in adults. These infections are also found quite often in girls and women. Men having ages below 50 and boys usually have lesser cases because of some differences in the structure of excretory system.

Types of UTIs

Urinary tract infections can either affect the upper or the lower part of the excretory system. Regular diagnosis should be carried out so that these infections don’t go unchecked. If the infection starts in the upper parts of excretory system, it is particularly dangerous as the diagnosis is also difficult in this case. The general symptoms of UTIs are shivering, nausea, sensation of vomit, high fever, fatigue and other related symptoms.

Commonly UTIs may be called as simple or complicated:

  • Simple UTIs are the benign ones as they do not invade other body parts and remain restricted to the excretory system. These infections usually start in a completely normal excretory system and can easily be cured with medications.
  • Complicated UTIs are the malignant ones as they do spread to other areas of the body as well. Antibiotics and other medications usually do not affect them at all. They are the result of certain abnormalities present in the body’s anatomy and other ulterior factors

Bacteria involved in UTIs

Many different kinds of bacteria are found to be responsible for causing such infections:

  • A bacterium named E. coli is found to be the cause of the most easily cured type of UTI.
  • Staphylococcus saprophyticus is another such strain causing the disease, particularly in young women.
  • Klebsiella enterococcus is another related bacterium.
  • Proteus mirabilis causes the infection in elder women.
  • Ureaplasma urealyticum and Mycoplasma hominis are some other bacteria found associated with certain UTI cases.
  • Pseudomonas aeruginosa is the type of bacteria that is associated with severe cases of UTI.
