Phylum Proteobacteria, Class Gammaproteobacteria, Order Enterobacteriales, Family Enterobacteriaceae, Genus Cosenzaea,
Cosenzaea myxofaciens (Cosenza and Podgwaite 1966) Giammanco et al. 2011 - type species of the genus.
Basonym: Proteus myxofaciens Cosenza and Podgwaite 1966.
Gram-negative rods. Motile by peritrichous flagella.
Facultatively anaerobic, growth temperature 37 ºC. Highly motile, resulting a thin film
of bacteria on the agar surface (swarming). S-type, non-pigmented colonies on
swarming inhibitory media.
Isolated only from living and dead gypsy moth larvae (Porthetria dispar L.).
The role in the production of disease in gypsy moth larvae has not been established.
