Another species of the genus Streptococcus of the family Streptococcaceae represents an important human pathogen in the perinatal field: Streptococcus agalactiae or group B streptococcus. Some important clinical differences as well as parallels between group A and group B streptococcus have been established in the past.
Introduction. During the 1980s, the genus Streptococcus that was formerly grouped as fecal streptococci or Lancefield D group streptococci was subdivided into three separate genera, namely Streptococcus, Lactococcus, and Enterococcus on the basis of 16S rRNA gene sequence-based assays.
Oct 19, 2014 · Abstract. This chapter discusses briefly the family Streptococcaceae and its three genera Streptococcus, Lactococcus, and Lactovum. The order Lactobacillales includes the family Streptococcaceae with three genera Streptococcus, Lactococcus, and Lactovum, in addition to closely related species currently referred to as the “ Lactococcus piscium ...
Streptococcus is a genus of gram-positive coccus (pl.: cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota.
28 The Family Streptococcaceae. Stephen Lory. Department of Microbiology and Immunobiology, Harvard Medical School, Boston, MA, USA. Abstract. This chapter discusses briefly the family Streptococcaceae and its three genera Streptococcus, Lactococcus, and Lactovum.
Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Older cultures may lose their Gram-positive character. Most streptococci are facultative anaerobes, and some are obligate (strict) anaerobes. Most require enriched media (blood agar).
