Leeuwenhoek observed motile microorganisms under a microscope from a decayed tooth.

Different specializations include bacteriology, mycology, protozoology, phycology, and immunology.

Scientists who study bacteria focusing on medical, agricultural, and biotechnological applications.

He created the first useful microscopes and used them to discover microscopic cells.

Known for making one of the first microscopes and studying plant cells and microbes.

The number of microbes is ten times that of human cells in the body.

The human mouth contains approximately 500 different species of bacteria.

Thiomargarit namibiensis is the largest bacterium visible to the naked eye.

The study of microorganisms, their functioning, and their impact on life.

Microbes produce half of the oxygen in Earth's atmosphere.

Diseases can spread through invisible, transmissible agents, discovered by Leeuwenhoek.

Mycoplasmas are the smallest known bacteria.

The 1918 influenza virus caused more deaths than World War 1.

A bacterial filter designed by C. Chamberland to identify viruses.

An infectious disease identified in 1898 as caused by a filterable agent.

Beneficial microorganisms that aid digestion and vitamin K production.

Microorganisms are essential in the production of curd, wine, and baked goods.

Medicines produced from microorganisms to combat bacterial infections.

First to discover the immune system in animals, showing its defense against infection.

Pioneer in searching for a 'magic bullet' drug against syphilis, created salvarsan.
