the upper vaginal and cervical anaerobic flora in menopausal women.	the upper vaginal and cervical bacterial flora, especially the anaerobic one which has a particular role in postoperative morbidity, was studied in 78 menopausal women between 48 and 78 yr of age. the aim of the present study was to compare the results obtained with those reported for bacterial flora in women of other age groups. the patients were divided into the following 3 groups. (i) twenty-eight healthy women with a natural menopause; (ii) 30 women, 2-6 mth after surgical menopause due to p ...	1981	7197644
faecal bacterial flora in patients with colon cancer and control subjects.	faeces from 10 colon cancer patients and from 10 control subjects were studied by quantitative and qualitative aerobic and anaerobic techniques using a variety of non selective, selective and differential media. in several cases, there were significantly different numbers of organisms of specific types recovered from the two groups studied. most prominent and meaningful findings were the higher frequency of isolation and counts of bacteroides species (especially b. fragilis group) and of c. para ...	1981	7199237
anaerobic bacteria in suppurative infections of the male genitourinary system.	cultures were done to determine the prevalence of anaerobic bacteria in 18 male patients with suppurative infections of the genitourinary tract. the types of infections studied were scrotal abscess, prostatic abscess, scrotal gangrene and perinephric abscess. anaerobic bacteria were recovered in 16 of the 18 specimens examined. these 16 specimens yielded a total of 48 anaerobic strains and 19 aerobic or facultative strains. the dominant organism isolated was bacteroides fragilis, which was found ...	1981	7206087
model of intraabdominal abscess in mice.	intraperitoneal inoculation of sterile mouse feces into mice produced intraabdominal abscesses. the addition of bacteroides fragilis increased the incidence and the number of abscesses.	1981	7216456
animal model for anaerobic lung abscess.	there are no satisfactory animal models for the study of anaerobic lung abscess. aspiration of food, gastric mucin, or hydrochloric acid, or any combination of these, along with oropharyngeal bacteria, is commonly believed to cause aspiration pneumonia and lung abscess. in the animal model described, none of the adjuvants was effective in producing anaerobic lung abscesses. anaerobic bacteria derived from dental scrapings of a healthy adult (peptococcus morbillorum, fusobacterium nucleatum, euba ...	1981	7216463

neuraminidases of bacteroidaceae die neuraminidasen von bacteroidaceen.	neuraminidases can be detected in members of the anaerobic gram-negative non-sporing rods (bacteroidaceae), especially in the genus bacteroides. b. fragilis, the most virulent species, has the highest neuraminidase activity, while the other intestinal species exhibit markedly lower activities or the enzyme is completely absent. members of the bacteroides oralis group, so far investigated, degrade only substrates of lower molecular weight.	1981	7223133
