What diseases are caused by Streptococcus?
In addition to streptococcal pharyngitis (strep throat), certain Streptococcus species are responsible for many cases of pink eye, meningitis, bacterial pneumonia, endocarditis, erysipelas, and necrotizing fasciitis (the 'flesh-eating' bacterial infections).
How many types of Streptococcus are there?
How many types of Streptococcus are there?
Most streptococci are oxidase-negative and catalase-negative, and many are facultative anaerobes (capable of growth both aerobically and anaerobically). In 1984, many bacteria formerly grouped in the genus Streptococcus were separated out into the genera Enterococcus and Lactococcus. Currently, over 50 species are recognised in this genus.
What is Streptococcus pyogenes infection?
Streptococcus pyogenes is a major human-specific bacterial pathogen that causes a wide array of manifestations ranging from mild localized infections to life-threatening invasive infections.[1] . Ineffective treatment of S. pyogenes infections can result in the postinfectious sequela acute rheumatic fever and post-streptococcal glomerulonephritis.
How is Streptococcus pneumoniae (strep throat) treated?
How is Streptococcus pneumoniae (strep throat) treated?
Control Prompt penicillin treatment of streptococcal pharyngitis reduces the antigenic stimulus and therefore prevents glomerulonephritis and acute rheumatic fever. Vancomycin resistance among the enterococci is an emerging microbial threat. Vaccines are under development. Streptococcus pneumoniae Clinical Manifestations
