The Streptococcus milleri Group

Abstract

The Streptococcus milleri group is newly recognized as a cause of pyogenic infection. It is important that microbiologists and physicians become aware of these organisms. The heterogeneous nature of this group of streptococci does mean that laboratories will have to use a combination of antigenic, physiologic, and hemolytic characteristics to identify these pathogenic streptococci. Physicians need to recognize that these microorganisms as a group are able to cause serious infections that may require prolonged treatment and/or surgical drainage of abscesses.

Streptococcus milleri in intraabdominal abscesses in children after appendectomy: incidence and course

“…In 1976, Parker and Ball associated this microorganism with other pyogenic infections [11]. The S milleri group is now recognized as both virulent and invasive, and some believe it is responsible for more suppurative infections than any other group of streptococci [12]. S milleri is a common inhabitant of the oral cavity and the gastrointestinal tract.…”

Development of an Ex Vivo Coculture System to Model Pulpal Infection by Streptococcus anginosus Group Bacteria

“…Bacteria from these sites have the capacity to spread from the pulpal chamber resulting in bacteraemia or abscesses at other sites in the body such as the liver and brain which can prove fatal (Verrall 1986;Whiley et al 1992). SAG bacteria have also been identified as primary colonisers of the pulpal chamber which enable further infection by other bacterial species.…”

Thermodynamic and transport properties of thoria–urania fuel of Advanced Heavy Water Reactor

“…Verrall et al [49][50][51][52] in fact showed that the volatiles segregate as microbubble/precipitate when their ions are implanted at high dose ($1.5-2 Â 10 20 ions m À2 ).…”
