isolation of obligate anaerobic bacteria from bovine abscesses in sites other than the liver.a survey in japan showed that of 2036 slaughtered cattle 58(3%) had abscesses in sites other than the liver. in 21 of the affected animals the lesions were pulmonary and in 32 abdominal (excluding hepatic); in five animals the lesions were found elsewhere (muscle 2, skin 2, bone 1). nineteen (33%) of the 58 cattle also had abscesses in the liver. obligate anaerobes alone were isolated from 17(29%) of the affected animals (fusobacterium necrophorum 14, bacteroides spp. 2, peptostreptococcus anaer ...19846389873

susceptibility of brain to aerobic, anaerobic, and fungal organisms.the utility of an experimental animal model is dependent on its ability to simulate the actual clinical situation. with a stereotaxic injection procedure, the susceptibility of rat brain to the spectrum of organisms commonly associated with human brain abscess was determined. two strains of escherichia coli were more infective than pseudomonas aeruginosa, staphylococcus aureus, and streptococcus pyogenes. even between the e. coli strains it was possible to document significant differences in deg ...19836409808
cefamandole therapy in hand infections.hand lacerations, especially when inadequately treated, may result in infections caused by aerobic or anaerobic bacteria. anaerobic infections most commonly result from human bite injuries in which there is contact between hand and mouth. the search continues for an ideal antibiotic to employ when anaerobic organisms are suspected. in this study cefamandole, a new cephalosporin antibiotic, was employed whenever anaerobic hand infections were suspected following trauma. in each patient quantitati ...19836415153
peptostreptococcus productus strain that grows rapidly with co as the energy source.anaerobic bacteria were enriched with a sewage digestor sludge inoculum and a mineral medium supplemented with b-vitamins and 0.05% yeast extract and with a 50% co-30% n2-20% co2 (2 atm [202 kpa]) gas phase. microscopic observation revealed an abundance of gram-positive cocci, 1.0 by 1.4 micron, which occurred in pairs or chains. the coccus, strain u-1, was isolated by using roll tubes with co as the energy source. based on morphology, sugars fermented, fermentation products from glucose (h2, ac ...19846430231

diffuse sclerosing osteomyelitis of the mandible.the medical care of patients with diffuse sclerosing osteomyelitis (dso) of the mandible has been unsatisfactory. the main reasons for this have been insufficient knowledge of the disease and its natural history, difficulties in establishing the correct diagnosis, and the unknown etiology. the clinical features and natural history of the disease were studied by means of repeated radiographic and scintigraphic recordings. the biopsy technique was improved by using a slowly rotating coarse trepan ...19846437998
surgical management of piriform sinus fistula.four cases of acute cervical abscess resulting from infection through the left piriform sinus fistula are described. the fistula seems to be related to the cause of infection in many of previously reported cases of acute suppurative thyroiditis or "recurrent lateral cervical fistula." complete removal of the fistula is essential to a permanent cure, and the guide of a fogarty catheter through the fistula is useful at operation for patients with repeated infection.19846465693
anaerobic bacteria isolated from foot infections in diabetic patients: in vitro susceptibility to nine antibiotics.twenty-nine isolates of anaerobic bacteria from foot infections in diabetic patients were tested, using the agar dilution method, for in vitro susceptibility to nine antimicrobial agents. imipenem and metronidazole showed excellent activity; clindamycin and chloramphenicol were next in terms of efficacy. cefoxitin and moxalactam demonstrated good activity, although three isolates of the bacteroides fragilis group were resistant to moxalactam. penicillin g, cefotaxime, and cefoperazone showed poo ...19846467279
production of menaquinones by intestinal anaerobes.ninety intestinal organisms (71 isolates from fecal samples of neutropenic patients with cancer or from various sites in patients with intraabdominal infections and 19 control strains) were examined by reverse-phase thin-layer chromatography for their ability to produce menaquinones in vitro. menaquinones were found in all of 24 organisms of the bacteroides fragilis group. two other bacteroides species, bacteroides disiens and bacteroides bivius, also produced menaquinones. a single isolate of b ...19846470528
anaerobic ureolytic bacteria from caecal content and soft faeces of rabbit.forty strains of ureolytic bacteria were isolated from the caecal content and soft faeces of seven rabbits by the anaerobic roll tube method and were characterized. the isolates were identified with clostridium coccoides, cl. innocuum, peptostreptococcus productus, p. micros, peptococcus magnus, fusobacterium russii and fusobacterium sp. urease activity of representative strains of the various species was also determined. the study indicated that strongly-ureolytic anaerobic bacteria are present ...19846490567
peptostreptococcal empyema in akinetic mutism.peptostreptococcal empyema occurred in a 54-year-old man who had suffered from diabetes mellitus and had been in akinetic mutism. ultrasonic tomogram was useful to detect the space of empyema and to identify the decrease in volume of the empyema space with treatment.19846492491
microorganisms isolated from infected aural fistulas.aural fistula is a congenital deformity of the external ear relatively common in orientals and rare in caucasians. suppuration tends to occur, and chemotherapy rather than surgical drainage should be attempted. however, the lack of information concerning infected aural fistulas has made appropriate chemotherapy difficult. microorganisms isolated from 13 cases of infected aural fistulas were studied from january 1981 to december 1982. six species and 22 strains were isolated; nonsporeforming facu ...19846492970
induction in rats of serum agglutinins to eubacterium, peptostreptococcus and coprococcus species by the faecal flora from patients with crohn's disease and healthy subjects.sera from patients with crohn's disease more often than those from other subjects contain agglutinins against anaerobic coccoid rods, identified as peptostreptococcus productus, eubacterium contortum (two strains) and coprococcus comes. the presence of antigens of the four coccoid rods in faeces of patients with crohn's disease and healthy subjects was investigated by inoculation of rats with faecal suspensions. antigens of the coccoid rods were detected in faeces from both patients with crohn's ...19846501880
characterization of peptostreptococcus asaccharolyticus glutamate dehydrogenase purified by dye-ligand chromatography.glutamate dehydrogenase (l-glutamate:nad+ oxidoreductase (deaminating); ec has been purified from peptostreptococcus asaccharolyticus in a single step using dye-ligand chromatography. the enzyme (gdh) was present in high yields and was stabilized in crude extracts. a subunit molecular weight of 49000 +/- 500 was determined by sds polyacrylamide gel electrophoresis and six bands were obtained after cross-linking the subunits with dimethyl suberimidate. this bacterial gdh was predominantl ...19846502134
intestinal water-soluble mucins in germfree, exgermfree and conventional animals.water-soluble intestinal mucins were investigated in germfree (gf), exgermfree (exg) and conventional (conv) rats and in gf and conv mice. after agar gel electrophoresis, all gf animals had similar specific band patterns demonstrated by pas and toluidine blue. these patterns, never seen in conv animals, disappeared in gf animals infected either with intestinal contents from conv rats or mono-infected with a mucin converting microorganism, labelled peptostreptococcus n. the intestinal microflora ...19846516849
in vitro susceptibility of anaerobic bacteria to ciprofloxacin (bay o 9867).about 80% of 70 clinical isolates of bacteroides fragilis were inhibited by 4 micrograms of ciprofloxacin (bay o 9867) per ml. the 90% mic of ciprofloxacin was 8 micrograms/ml for other bacteroides species, 2 micrograms/ml for peptococcus species, 8 micrograms/ml for peptostreptococcus species, and 16 micrograms/ml for clostridium and eubacterium species.19846517561
