Bacterial pathogens

Infections in specific tissue[edit]

Bacterial pathogens often cause infection in specific areas of the body. Others are generalists.

• 
  Bacterial vaginosis is a condition of the vaginal microbiota in which an excessive growth of Gardnerella vaginalis and other mostly anaerobic bacteria displace the beneficial Lactobacilli species that maintain healthy vaginal microbial populations.^[13]
  
• 
  Bacterial meningitis is a bacterial inflammation of the meninges, which are the protective membranes covering the brain and spinal cord.
  
• 
  Bacterial pneumonia is a bacterial infection of the lungs.
  
• 
  Urinary tract infection is predominantly caused by bacteria. Symptoms include the strong and frequent sensation or urge to urinate, pain during urination, and urine that is cloudy.^[14] The most frequent cause is Escherichia coli. Urine is typically sterile but contains a variety of salts, and waste products.^[15] Bacteria can ascend into the bladder or kidney and causing cystitis and nephritis.
  
• 
  Bacterial gastroenteritis is caused by enteric, pathogenic bacteria. These pathogenic species are usually distinct from the usually harmless bacteria of the normal gut flora. But a different strain of the same species may be pathogenic. The distinction is sometimes difficult as in the case of Escherichia.
