Communicable Diseases : Diseases caused by Bacteria

Millions of bacteria reside in our body and act as the first line of defense against infection. However, some bacteria enter the human body and release toxin, degenerate a tissue and cause diseases. The various bacterial diseases are: Tuberculosis- Tuberculosis is caused by Mycobacterium tuberculosis. The incubation period. It is approximately three to six weeks. Rest, Proper diet, such as protein rich diet and drugs such as Streptomycin, Isoniazid and Rifampicin are treatment. Leprosy- The leprosy bacillus Mycobacterium leprae is another species of the Mycobacterium genus. Leprosy has a long incubation period, i.e., 3-5 years. Dapsone (Diamino diphenyl sulphone), Rifampicin and Clofazimine are the drugs. Cholera- Vibrio cholerae is the causative agent of this disease. The incubation period, i.e. from 6 hours to 2-3 days. Diphtheria- the causative agent of diphtheria is Corynebacterium diphtheria. Antibiotics and Surgical removal are treatments. Tetanus- is a fatal but preventable disease. It is caused by Clostridium tetani. Its incubation period is usually 6 to10 days. Human Tetanus Immunoglobulin (HTIG) is an effective antitoxin. Plague- the causative agent of plague Yersinia pestis. The incubation period is 1 to 3 days. Typhoid- Salmonella typhi is the causative agent of typhoid Incubation period is 10-14 days. Pneumonia- Bacterial pneumonia is most common and is caused by Streptococcus pneumoniae or Pneumococcus. Pertussis- Bordetella pertussis is the causative agent of whooping cough. The incubation period of whooping cough is usually 7-14 days. Gonorrhea- is a sexually transmitted disease, common in both males and females. Neisseria gonorrhoeae causes gonorrhea. Syphilis is a highly infective sexually transmitted disease caused by Treponema pallidum. Cholera is caused by the pathogen Vibrio cholerae and it is caused by the intake of contaminated food and water. The incubation period of this disease is 1 to 2 days.
