The family aerococcaceae

Abstract

The family Aerococcaceae is a member of the order Lactobacillales, phylum Firmicutes. It comprises the genera Aerococcus, Abiotrophia, Dolosicoccus, Eremococcus, Facklamia, Globicatella, and Ignavigranum and has been created on the basis of the phylogenetic position of its members as analyzed by comparative 16S rRNA gene sequence analysis. Members are Gram-positive, nonmotile and non-spore-forming, facultative anaerobic, catalase-negative ovoid cocci or coccibacilli. Lysine has been reported to occur as the diagnostic diamino acid in the peptidoglycan. The habitat includes a wide range of environments, e.g., human specimens, household, schoolrooms, yard, street and hospital environments, and marine sites, and they have also been reported in human infections. This chapter is a short update of species described since 2005, which are not covered in the chapter Aerococcaceae in Bergey's Manual of Systematic Bacteriology, 2nd edition.
