diphtheria

Examples of diphtheria in the following topics:

• Diphtheria

  • Diphtheria is an upper respiratory tract illness caused by Corynebacterium diphtheriae, a facultative, anaerobic, Gram-positive bacterium.
  • A milder form of diphtheria can be restricted to the skin .
  • In the United States, for example, there were 52 reported cases of diphtheria between 1980 and 2000; between 2000 and 2007, there were only three cases as the diphtheria–pertussis–tetanus (DPT) vaccine is recommended for all school-age children.
  • Diphtheria toxin is produced by C. diphtheriae only when it is infected with a bacteriophage that integrates the toxin-encoding genetic elements into the bacteria.
  • Corynebacterium diphtheriae produces toxins that can affect the skin by causing skin lesions, as shown here.

• Pharyngitis

  • The most common is Group A streptococcus, but others include Corynebacterium diphtheriae, Neisseria gonorrhoeae, Chlamydophila pneumoniae, and Mycoplasma pneumoniae.
  • Diphtheria is a potentially life threatening upper respiratory infection caused by Corynebacterium diphtheriae.
  • As a result of childhood vaccination programs, diphtheria has has been largely eradicated in developed nations, but it is still reported in the Third World, and, increasingly, in some areas in Eastern Europe.

• Direct Damage

  • Examples of bacteria that will damage tissue by producing toxins, include, Corynebacterium diphtheriae and Streptococcus pyogenes.
  • Specifically, Corynebacterium diphtheriae causes diphtheria, which isa disease of the upper respiratory tract.
  • It produces a toxin, diphtheria toxin, which alters host protein function.

• Vaccination

  • Some vaccinations are composed of live suspensions of weak or attenuated cells or viruses, deadened cells or viruses, or extracted bacterial products such as the toxoids used to immunize against diphtheria and tetanus.

• Immune Complex Autoimmune Reactions

  • Arthus reactions have been infrequently reported after vaccination against diphtheria and tetanus.

• Koch and Pure Culture

  • By using his methods, Koch's pupils found the organisms responsible for diphtheria, typhoid, pneumonia, gonorrhoea, cerebrospinal meningitis, leprosy, bubonic plague, tetanus, and syphilis.

• Ecological Associations Among Microorganisms

  • Pathogenic bacteria are a major cause of human death and disease and cause infections such as tetanus, typhoid fever, diphtheria, syphilis, cholera, foodborne illness, leprosy, and tuberculosis.

• Bacterial Eye Diseases

  • Corynebacterium diphtheriae causes membrane formation in conjunctiva of non immunized children.
