Streptococcus milleri in the appendix.
The appendix was investigated as a possible habitat of Streptococcus milleri. Both normal and inflamed appendices were examined and the isolation rates compared. S. milleri was present in a quarter of the normal appendices and more than half of those associated with apendicitis--a difference that was statistically highly significant. The isolation rates throughout were indepencent of age. There...
متن کاملStreptococcus anginosus ("Streptococcus milleri"): the unrecognized pathogen.
"Streptococcus milleri" is an unofficial name that has been applied to a group of streptococci which, although basically similar, show various hemolytic, serological, and physiological characteristics. The species name Streptococcus anginosus has recently been recognized as the approved name for these organisms. Streptococci known as "S. milleri" have been implicated as etiologic agents in a va...
متن کاملCariogenicity of a lactate dehydrogenase-deficient mutant of Streptococcus mutans serotype c in gnotobiotic rats.
A lactate dehydrogenase-deficient (Ldh-) mutant of a human isolate of Streptococcus mutans serotype c was tested in a gnotobiotic rat caries model. Compared with the wild-type Ldh-positive (Ldh+) strains, it was significantly (alpha less than or equal to 0.005) less cariogenic in experiments with two different sublines of Sprague-Dawley rats. The Ldh- mutant strain 044 colonized the oral cavity...
متن کاملThoracic infection caused by Streptococcus milleri.
The objective of this study was to increase our understanding of the importance of members of the Streptococcus milleri (SM) group as respiratory pathogens, by studying the epidemiological and clinical features of thoracic infections caused by this group and comparing the epidemiology and prognosis of empyema caused by SM with cases of pneumococcal aetiology. The clinical histories and microbio...
متن کاملThe collagen binding protein Cnm contributes to oral colonization and cariogenicity of Streptococcus mutans OMZ175.
Streptococcus mutans is the etiological agent of dental caries and one of the many bacterial species implicated in infective endocarditis. The expression of the collagen-binding protein Cnm by S. mutans has been associated with extraoral infections, but its relevance for dental caries has only been theorized to date. Due to the collagenous composition of dentinal and root tissues, we hypothesiz...
