The intra- and intergeneric relationships of the genus Staphylococcus, and the phylogenetic position of Peptococcus saccharolyticus and Micrococcus (Staphylococcus salivarius), were investigated by comparative oligonucleotide cataloguing of 16S rRNA. All the staphylococci investigated form a phylogenetically coherent group at the genus level that, in addition, contains the anaerobic species Peptococcus saccharolyticus. The genus Staphylococcus belongs to the broad Bacillus-Lactobacillus-Streptococcus cluster that is defined by Gram-positive bacteria with a low DNA G+C content. Micrococcus mucilaginosus is not a genuine member of the genus Micrococcus. The binary matching coefficients between the 16S rRNA of Micrococcus mucilaginosus and those representatives of the Arthrobacter/Micrococcus group and related genera indicate that Micrococcus mucilaginosus should be regarded as a member of a new genus.

Review
Clindamycin, the 7(S)-chloro-7-deoxy derivative of lincomycin, has stood the test of time in the treatment of anaerobic infections. Clindamycin inhibits protein synthesis by acting on the 50S ribosomal subunits of bacteria. The colitis resulting from the use of clindamycin has been extensively studied and is now easily manageable. Although newer antibiotics active against anaerobes are available, clindamycin remains a reliable and well-tested antibiotic for use in anaerobic infections.

A strictly anaerobic gram-positive coccus, identified as Peptococcus niger, that developed sulfatase activity towards steroid-3-sulfate esters was isolated from human fecal material. This strain desulfated the arylsulfate esters estrone-3-sulfate (100%) and beta-estradiol-3-sulfate (50%); only trace amounts of desulfated estriol-3-sulfate were found. In addition, alkylsulfatase activity was found towards the 3 alpha-sulfates of 5 alpha-androstane-17-one and 5 beta-androstane-17-one and towards the 3 beta-sulfates of 5 alpha-androstane-17-one, delta 5-androstene-17-one, 5 alpha-pregnane-20-one, and delta 5-pregnene-20-one, all of which were 100% desulfated. No sulfatase activity was found towards the 17-sulfate esters of beta-estradiol or delta 4-androstene-3-one-17 alpha-ol. The nonsteroid arylsulfate esters paranitrophenyl sulfate, paranitrocatechol sulfate, and phenolphthalein disulfate were desulfated 70, 40, and 40%, respectively. In addition to its sulfatase activity, this strain also developed C-17 oxidoreductase activity towards the estrogens and androsta(e)nes and C-3 oxidoreductase activity towards androsta(e)nes and pregna(e)nes.

Review
Intra-abdominal sepsis that involves multiple aerobic and anaerobic bacteria derived from the colonic flora was studied in Wistar rats to determine the relative roles of various microbial species. The rats challenged with pooled colonic contents showed a biphasic disease. Initially, there was acute peritonitis, Escherichia coli bacteremia, and high mortality. In rats that survived this acute peritonitis stage, intra-abdominal abscesses developed, and anaerobic bacteria were the preponderant organisms. Subsequent experiments showed that antibiotics directed against coliforms prevented mortality, whereas agents active against anaerobes reduced the incidence of abscesses. Challenges with Escherichia coli alone produced bacteremia and death, whereas pure cultures of Bacteroides fragilis caused intra-abdominal abscesses. These observations suggest that both coliforms and anaerobes are important pathogens in intra-abdominal sepsis, although the different types of microbes appear to play distinctive roles in the sequence of pathological events.

A 1330 base-pair fragment of a 16S rRNA gene has been amplified, cloned and sequenced. Comparison to other 16S rRNA sequences of eubacteria showed that P. niger represents a deep branch within the subdivision "Gram-positive with Gram-negative cell walls". It is not related to peptostreptococci, representatives of this genus studied so far are more closely related to clostridia.

Peptococcus indolicus (formerly Micrococcus indolicus) is an asaccharolytic anaerobic coccus that is frequently isolated from udder secretions from cases of heifer and dry-cow mastitis (summer mastitis). To facilitate better identification and its differentiation from Peptococcus asaccharolyticus, a variety of biochemical, enzymatic, and serological properties were studied. Seventy-nine strains of P. indolicus of bovine origin and 10 strains of P. asaccharolyticus of human origin were examined using the API 20A and API-ZYM test kit systems. In addition, production of extracellular enzymes by using sensitive substrate-containing agar plate tests, production of peptocoagulase (a plasma-clotting factor), hemolytic properties, metabolic end products by gas chromatography, and serological characteristics with a set of P. indolicus typing antisera were investigated. P. indolicus and P. asaccharolyticus were not satisfactorily differentiated solely by the API 20A system. P. indolicus differed from P. asaccharolyticus in producing H(2)S, reducing nitrate to nitrite, producing peptocoagulase, possessing alkaline phosphatase, and producing large amounts of propionate from lactate. Moreover, none of the strains of P. asaccharolyticus was typable with the P. indolicus typing antisera. The majority (88%) of P. indolicus strains also gave weak hydrolysis of ribonucleic acid, and 6 out of 79 produced deoxyribonuclease. All strains in this study were sensitive to metronidazole (5 mug) by disk diffusion tests.
