Family of bacteria

Pasteuriaceae Pasteuria ramosa spores Scientific classification Domain: Bacteria Kingdom: Bacillati Phylum: Bacillota Class: Bacilli Order: Bacillales Family: Pasteuriaceae Laurent 1890 Genus[1][2] Pasteuria Synonyms "Pasteurieae" Trevisan 1889

**Pasteuriaceae** is a [family](/source/Family_(taxonomy)) of nonmotile [Gram-positive](/source/Gram-positive) [bacteria](/source/Bacteria). They are moderately to strongly resistant to heat.[3] [Species](/source/Species) in this family produce a septate [mycelium](/source/Mycelium) with one refractile [endospore](/source/Endospore). The mycelium grows bigger on one end to form sporangia and sometimes endospores.[4] The size of the endospores is different for each species of the genus *Pasteuria*. Species of the family of Pastueriaceae are endoparasitic in plant, soil, and freshwater invertebrates.[3][4]

## Parasitism

Bacteria of the Pasteuriaceae family are endoparasitic within nematodes or [cladoceran](/source/Cladocera) hosts. After the infection, the host gets castrated by the parasite and shows gigantism. The infection pathway is not fully discovered yet. The core of the endospores is covered by glycoproteins that are presumed to be involved in the attachment of the endospores to the invertebrates host.[5][6][7]
