Study Notes
Spore-Forming Anaerobe
- An anaerobic bacterium that forms spores is capable of producing a potent toxin.
- The bacterium's anaerobic growth rate is reduced, ranging from 8% in Lactobacillus 173 to 67% in Bacillus cereus.
- This reduction in growth rate occurs when 100% COâ‚‚ is used as opposed to an atmosphere with 5% COâ‚‚ and 95% Nâ‚‚.
Trematode Cysts
- Killing cyst stages for the following Trematodes:
- Fasciola hepatica: 0.03
- Clonorchis senensis: 0.15-0.20
- Opisthorchis viverrini: 0.10
- Paragonium westermani: 0.10
Protein Deficiency
- Severe nutritional deficiencies can lead to advanced protein deficiency in children, known as kwashiorkor or protein-energy malnutrition.
