Pasteuria ramosa

Pasteuria ramosa is a gram-positive, endospore-forming bacterium in the Bacillus/Clostridia clade within Firmicutes. It is an obligate pathogen of cladoceran crustaceans from the genus Daphnia. Daphnia is an umbrella term for a number of small freshwater creatures including D. magna, P. ramosa's most popular host target. Other hosts include D. pulex, D. longispina, , and . An established and widely used coevolutionary model of host-pathogen interactions exists with P. ramosa and D. magna.
