Types of Microorganisms and Infections

Bacteria

Bacteria: Very small, single-celled organisms, abundant in various environments, including the human body. While some bacteria can cause diseases, others play essential roles in digestion and food production.

Viruses

Viruses: Much smaller than bacteria, viruses can only replicate inside living cells. They cause a wide range of human infections, from the common cold to serious conditions like AIDS. Unlike bacteria, viruses are not susceptible to antibiotics.

Pathogenic Fungi

Pathogenic Fungi: Including moulds and yeasts, these organisms can cause infections such as ringworm and thrush.

Protozoa

Protozoa: Microscopic organisms larger than bacteria, responsible for infections like malaria. Transmission can occur through ingestion, sexual contact, or insect vectors.

Worms

Worms: While not always microscopic, pathogenic worms can spread infections between individuals. Examples include threadworm and tapeworm.

Prions

Prions: Infectious protein particles, associated with diseases like (New) Variant Creutzfeldt-Jakob Disease (vCJD).
