Gram-positive anaerobic cocci.
Gram-positive anaerobic cocci (GPAC) are a heterogeneous group of organisms defined by their morphological appearance and their inability to grow in the presence of oxygen; most clinical isolates are identified to species in the genus Peptostreptococcus. GPAC are part of the normal flora of all mucocutaneous surfaces and are often isolated from infections such as deep organ abscesses, obstetric...
متن کاملDevelopment of a flow chart for identification of gram-positive anaerobic cocci in the clinical laboratory.
Gram-positive anaerobic cocci (GPAC) are a heterogeneous group of organisms that are isolated from clinical specimens more often than any group of anaerobic bacteria except Bacteroides species, yet many strains are still difficult or impossible to identify in the diagnostic laboratory. In this study, a total of 124 strains, including 13 reference strains of GPAC species and 111 isolates that ha...
متن کاملPathogenicity of anaerobic gram-positive cocci.
The pathogenicity of 20 strains of facultative or anaerobic gram-positive cocci (AGPC) was investigated by injecting them alone or mixed with other flora into mice, utilizing the subcutaneous abscess model. Abscesses induced by a mixture of two organisms were uniformly larger than those induced by single organisms. The relationships among seven AGPC strains, eight aerobes, and two Bacteroides s...
متن کاملAchromopeptidase for lysis of anaerobic gram-positive cocci.
Achromopeptidase, which has potent bacteriolytic activity for most of the gram-positive aerobic bacteria, was for the first time used for the lysis of anaerobic cocci. Most of the lysozyme-resistant gram-positive anaerobic cocci were lysed with this new enzyme. Peptococcus magnus was the only organism tested resistant to achromopeptidase. P. saccharolyticus was quite unusual because it was very...
متن کاملIdentification of pili on the surface of Finegoldia magna--a gram-positive anaerobic cocci.
Pili have only been discovered in the major Gram-positive pathogens in the past decade and they have been found to play an important role in colonisation and virulence. Pili have been shown to have many important functions including attachment to host tissues, mediating bacterial aggregation, biofilm formation and binding to proteins in the extracellular matrix. In this study, sortase-dependent...
