“…In contrast to other series in which the polymicrobial origin of the thoracic infection was associated with gastrointestinal origin and the presence of gastropleural fistulae [17,24], this study revealed that polymicrobial infection was also associated with respiratory origin and bronchopleural fistulae. This is probably related to the fact that all polymicrobial infections in this series, except for one (mediastinitis in Ludwig's angina), were linked to respiratory or gastrointestinal tract procedures, indicating that the procedure is a decisive factor for the concomitant presence of other pathogens.…”

“…According to other reports, the incidence of thoracic infection due to SM has ranged between 10-32% of all SM infections [12,[17][18][19][20][21][22] and between 24-57% of suppurative thoracic infections [23,24]. Most patients in the present series were adult males (3:1), as has been the experience of others [11,21].…”

The group Streptococcus milleri (SM) includes several species of pathogenic streptococci associated with pyogenic infections. In 1956 O. Guthof was the first to use the name SM when referring to nonhaemolytic species of streptococci found in the oral cavity [1]. WHILEY and coworkers [2,3], through phenotypic and deoxyribonucleic acid (DNA)-DNA hybridization studies, affirmed the existence of at least three well-differentiated species: S. constellatus, S. intermedius and S. anginosus. Many authors prefer to continue using the term SM for the three species for two reasons: firstly, because the term is useful to the clinician, since it warns of the presence of a suppurative process [4,5] and secondly, because the three species appear to be equally represented as a cause of thoracic infection [6,7].The SM group is part of the usual flora of the mouth, but its true prevalence is unknown. It is also found among normal faecal flora in 16-67% of healthy adults and has been isolated from normal appendix and from vaginal secretions [3,[8][9][10]. The most important clinical feature of these micro-organisms is their tendency to cause suppurative infections at various sites, ranging from dental abscesses to deep visceral abscesses [1,4,8,[11][12][13][14][15].The purpose of this study was to contribute to a better understanding of the importance of members of the SM group as respiratory pathogens, by studying the epidemiological and clinical features of thoracic infections caused by SM and contrasting the features of empyema caused by SM with those in cases of pneumococcal aetiology. Patients and methodsA review was undertaken of the clinical histories and microbiological reports of episodes of infection by SM isolated from clinically significant samples in our institution, an acute care general hospital serving around 250,000 inhabitants, between January 1988 and December 1995. Only those cases in which some type of thoracic infection was diagnosed were analysed. The cases of pneumococcal empyema that occurred during the same period were also analysed. For the purposes of this study, thoracic infection was defined as all processes of an infectious nature localized to any of the organs, systems or anatomical structures in the thoracic cavity, except intravascular lesions with endothelial infection. Infections were considered to be acquired The clinical histories and microbiology reports were reviewed in 27 cases of thoracic infection caused by SM over a period of 8 yrs. Cases of pneumococcal empyema that occurred during the same period were also analysed.Diagnoses were made of cases of empyema, including six with pneumonia and one with pulmonary abscess, three cases of pneumonia and two of mediastinitis. In 17 cases, SM was the only pathogen isolated. There was a history of instrument or surgical procedures on the digestive or respiratory tract in 59%. Secondary bacteraemia was documented in three cases. The treatment administered, a combination of antibiotics and surgery, was successful in 22 of 27 (81%) of cases. All strai...

Streptococci that produced acetoin and alkaline phosphatase, hydrolyzed arginine, and fermented trehalose but did not produce pyrrolidonylarylamidase or P-glucuronidase, split hippurate, or ferment ribose or glycogen were collected and compared, These streptococci were considered members of the unapproved species 'LStreptococcus millen'," but most of them would fit the description of one of three approved species: Streptococcus anginosus, Streptococcus constellatus, or Streptococcus intermedius. Most were recent clinical isolates. Some hydrolyzed esculin and fermented lactose, while others did pot. Some fermented mannitol and rafknose. Many were beta-hemolytic, and several reacted to antiserum of Lancefield group A, C, F, or G. From a total of 111 strains, 40 were selected for comparison of their deoxyribbnucleic acid (DNA) base sequence similarities by DNA-DNA hybridization on membrane Filters. All biotypes, hemolytic types, and serotypes were included, as well as the type strains of S. anginosus, S. constellatus, and S . intermedius, and Lancefield group F Streptococcus sp., plus two strains derived from GuthoPs '(S. millen'" isolates. The results showed considerable genetic similarity within the group. DNA from most strains hybridized at a level of 70% or more of the homologous control, even under very stringent conditions. There was somewhat less homology between DNAs of some of the least reactive strains (lactose, mannitol, and esculin negative) and the most reactive strains (lactose, mannitol, and esculin positive). The Lancefield F strain and the type strains of S. anginosus and S.constellatus were genetically similar. Traits such as hemolysis and lactose fermentation could not be ascribed to plasmids. The results support the unification of these streptococci into a single species.

Summary. Serological variation in 71 oral isolates and three reference strains of Streptococcus milleri was examined. Antisera were raised by immunising rabbits with cells of 10 selected strains, followed by absorption of non-specific antibodies. Double diffusion of the typing sera and the Rantz and Randall extracts of the strains in agar gel demonstrated that 70 strains were divided into 10 serotypes (a-j) on the basis of cell-surface carbohydrate antigens. Only four strains were untypable. The typing scheme proposed depends on type antigens other than the Lancefield group antigens
