Study Notes
Food Poisoning and Bacteria
- Bacillus cereus is the organism most likely responsible for food poisoning due to ingestion of fried rice.
- It is frequently misdiagnosed.
Bacillus Anthracis
- Bacillus anthracis is associated with 'Medusa head' colonies on nutrient agar.
- The correct statement concerning Bacillus anthracis is that it is a zoonotic disease with no arthropod vector.
- The major reservoir for B. anthracis infection is animals, particularly herbivores.
- Important virulence determinants of B. anthracis include capsule and toxins.
- A cell-free vaccine is available against anthrax.
- Cutaneous anthrax has a good prognosis, while inhalation anthrax has a poor prognosis.
Gas Gangrene and Relapsing Fever
- Gas gangrene is most likely caused by Clostridium perfringens.
- Borrelia recurrentis is the cause of relapses in relapsing fever.
- The correct pairing of organism and mode of transmission is Borrelia recurrentis and lice.
- Epidemic and endemic relapsing fever can be distinguished by the lab test of PCR (polymerase chain reaction).
Zoonotic Diseases and Weil's Disease
- Weil's disease is a zoonotic disease, and each of the following statements about it is correct, except one: leptospirosis is not transmitted by human-to-human contact.
- Brucellosis is a zoonotic disease, but it is not the correct answer to any of the above questions.
- Streptobacillus moniliformis is associated with the 'string of pearl' colonies on penicillin-containing medium.
