A WEB-SURFER'S GUIDE TO BACTERIA ASSOCIATED WITH INFECTIONS IN HUMANS
It is convenient for microbiologists and clinicians to consider the many streptococci associated with infections in humans as belonging to a number of groups - (follow the blue links)
(For former streptococci not listed below, see - Abiotrophia, Atopobium, Enterococcus, Gemella, Lactococcus, Ruminococcus)
Beta-haemolytic, pyogenic streptococci - S. agalactiae, S. canis, S. dysgalactiae dysgalactiae, S. dysgalactiae equisimilis, S. equi equi, S. equi zooepidemicus, S. iniae, S. porcinus, S. pyogenes
Microaerophilic, pyogenic streptococci (Streptococcus "milleri") - S. anginosus, S. constellatus constellatus, S. constellatus pharyngidis, S. intermedius - (it is convenient to consider these members of the oral flora separately from the following) -
Oral streptococci - including:
- the "mitis" group (alpha-haemolytic - Streptococcus "viridans") - S. mitis, S. oralis, S. sanguinis, S. cristatus, S. gordonii, S. parasanguinis;
- the "salivarius" group (non-haemolytic) - S. salivarius, S. vestibularis;
- the "mutans" group (tooth-surface streptococci) - S. criceti, S. mutans, S. ratti, S. sobrinus
Odd streptococci which do not fit into the main groups - S. acidominimus, S. bovis, S. equinus, S. pneumoniae, S. suis
