Streptococcus pyogenes is the bacterium responsible for causing strep throat, a common bacterial infection of the throat.
Influenza virus primarily spreads through airborne droplets that are released when an infected person coughs or sneezes.
Malaria is caused by protozoa of the genus Plasmodium, which are transmitted to humans by Anopheles mosquitoes.
Prokaryotic cells are characterized by the lack of a nucleus, containing their genetic material in the nucleoid region.
Penicillin is derived from fungi in the Penicillium genus, which naturally produce this antibiotic compound.
AIDS is caused by the Human Immunodeficiency Virus (HIV), which affects the immune system.
Antigens are molecules capable of inducing an immune response, primarily by triggering the production of antibodies.
Streptococcus mutans are bacteria that play a major role in the development of dental cavities by metabolizing sugars and producing acid.
Viruses are characterized by their requirement for a host cell to replicate, as they cannot reproduce independently.
The flagellum is a tail-like structure that enables the motility of a bacterial cell, allowing it to move towards favorable environments.
Saccharomyces cerevisiae, also known as baker's yeast, is used in bread fermentation, converting sugars into carbon dioxide for dough leavening.
