Study Notes
Viral Infections & Prions
- Viral infections are transmitted through various routes, such as aerosols, body fluids, insect vectors, fecal-oral, and mother to fetus.
- Treatment of viral infections often relies on antiviral drugs, which inhibit viral replication.
- Prevention involves strategies like immunization, hygiene practices, and avoiding contact with infected individuals.
- Prions are infectious proteins that lack genetic material.
- They differ from viruses in their structure, as viruses contain genetic material enclosed in a protein capsid.
Fungal Infections
- Fungal infections are classified based on their location and severity.
- Cutaneous fungal infections involve the skin, while mucocutaneous infections affect both skin and mucous membranes.
- Systemic mycoses refer to infections that spread throughout the body.
- Systemic fungal infections are often challenging to treat due to the similarities between fungal and human cells, making it difficult to target specific fungal proteins.
- Immunocompromised individuals, such as those with weakened immune systems, are particularly susceptible to systemic mycoses.
- Dermatophytes are a group of fungi that cause skin infections like ringworm.
- Candida species are fungi that can cause mucocutaneous infections, such as thrush.
Protozoan Infections
- Protozoa are eukaryotic organisms that can cause infections.
- Trophozoites are the active, feeding, and reproducing stage of protozoan parasites.
- Protozoa are spread through various mechanisms, including contaminated water, food, and vectors like insects.
