Antibiotic
Bacteria that cause disease.
Pathogenic bacteria
A microscopic particle that gets inside a cell and often destroys the cell.
Virus

Spirilla
A thick-walled protective spore that forms inside a bacterial cell and resists harsh conditions.
Endospore
The process in which nitrogen-fixing bacteria take in nitrogen from the air and change it to a form that plants can use.
