Streptococcus (Non-Group D)

Streptococcus (Non-Group D)

Streptococcus are gram-positive, facultatively anaerobic, catalase-negative microorganisms. They are primarily pathogenic but some do reside as microbial flora in various regions of humans and animals. They live in chains and are nonmotile. Group D Streptococcus has been reclassified as an Enterococcus.
