aminopeptidase activities in peptostreptococcus spp. are statistically correlated to gelatin hundred peptostreptococcus isolates from five species were assessed for their ability to hydrolyze gelatin. most peptostreptococcus magnus (95.8%) and peptostreptococcus micros isolates (79.0%) hydrolyzed gelatin in contrast to peptostreptococcus asaccharolyticus (8.0%), peptostreptococcus anaerobius (10.0%), and peptostreptococcus prevotii isolates (16.7%). gelatin hydrolysis in peptostreptococcus magnus and peptostreptococcus micros isolates correlated (r = 0.80; p = 0.0019) with more amin ...19989606913
bacterial interference in the nasopharynx following antimicrobial therapy of acute otitis media.the effect on the nasopharyngeal bacterial flora of therapy for 10 days with co-amoxiclav or cefprozil was studied in 50 children with acute otitis media. before therapy, potential pathogens (streptococcus pneumoniae, haemophilus influenzae and moraxella catarrhalis) were isolated in 14 (56%) of those treated with co-amoxiclav and 15 (60%) of those treated with cefprozil. following therapy, the reduction in the number of these pathogens was the same in the two groups. however, differences betwee ...19989598781

effect of red blood cells on the growth of porphyromonas endodontalis and microbial community development.establishment of a microbial community in the root canal system depends on numerous factors, of which nutrient availability may be one of the most important. we hypothesized that the presence of red blood cells or hemoglobin in this environment could cause shifts in microbial composition of communities, resulting in organisms such as porphyromonas endodontalis becoming more dominant. an in vitro model system using mixed, batch cultures was performed with the bacteria p. endodontalis, fusobacteri ...19989573801
ammonia-hyperproducing bacteria from new zealand ruminants.pasture-grazed dairy cows, deer, and sheep were tested for the presence of ammonia-hyperproducing (hap) bacteria in roll tubes containing a medium in which tryptone and casamino acids were the sole nitrogen and energy sources. colonies able to grow on this medium represented 5.2, 1.3, and 11.6% of the total bacterial counts of dairy cows, deer, and sheep, respectively. a total of 14 morphologically distinct colonies were purified and studied further. restriction fragment length polymorphisms of ...19989572953

the sequences of small proteins are not extensively optimized for rapid folding by natural selection.the thermodynamic stabilities of small protein domains are clearly subject to natural selection, but it is less clear whether the rapid folding rates typically observed for such proteins are consequences of direct evolutionary optimization or reflect intrinsic physical properties of the polypeptide chain. this issue can be investigated by comparing the folding rates of laboratory-generated protein sequences to those of naturally occurring sequences provided that the method by which the sequences ...19989560214

chronic sinusitis in children, sinusitis is a common, generally uncomplicated, and self limiting disease which drops with age. the diagnosis is difficult because of relatively non specific signs and symptoms that overlap with viral upper respiratory infection and allergy. plain paranasal sinus radiographs are not adequate, in determining the extent of involvement in recurrent or chronic sinusitis and so ct scan has become the standard. viral illness appears to be the most common predisposing factor. immune defect ...19979444376
periodontitis patient and the spouse: periodontal bacteria before and after treatment.suspected periodontal pathogens can be transmitted between spouses. the treatment response may be unsuccessful in periodontitis patients, if the spouse harbors these bacteria. the aim of the present 6-month follow-up study was to clarify whether the microbiological treatment outcome of periodontitis patients is related to the detection of suspected periodontal pathogens in the saliva of the spouse. 10 patients with advanced periodontitis and their spouses were included in the study. the patients ...19979442426
