Study Notes
Meningococcal Meningitis
- Most cases in Africa and the Middle East are caused by serogroups A and C, while in Europe, it is caused by serogroup B.
- Vaccination is the best prevention method, which includes antigens against serogroups A, C, Y, and W135.
Bacterial Characteristics
- Cocci are catalase-positive and oxidase-negative.
- Gram-positive bacilli are aerobic and non-sporing.
Listeria
- Listeria is a Gram-positive bacterium that is commonly found in animals, plants, and soil.
- It can cause opportunistic infections, especially in immunocompromised patients.
- It is distributed worldwide.
Diseases and Treatment
- Meningitis can be caused by Listeria, and specific therapy must be guided by antibiotic susceptibility tests.
- Diphtheria can be caused by the tox gene and can be treated with antitoxin.
- Tetanus can be caused by spores, especially in wounded persons without a previous vaccination history or in circumcision wounds.
This quiz covers the prevention methods of meningococcal meningitis, including vaccination and antigen types.
