Many bacterial species are named after people, either the discoverer or a famous person in the field of microbiology.
For example, Salmonella is named after D.E.
Salmon, who discovered it (albeit as "Bacillus typhi"[1]).
[2] For the generic epithet, all names derived from people must be in the female nominative case, either by changing the ending to -a or to the diminutive -ella, depending on the name.
[3] For the specific epithet, the names can be converted into either adjectival form (adding -nus (m.), -na (f.), -num (n.) according to the gender of the genus name) or the genitive of the Latinised name.
