| accuracy of the e test for determining antimicrobial susceptibilities of staphylococci, enterococci, campylobacter jejuni, and gram-negative bacteria resistant to antimicrobial agents. | we compared the results of the e test mic method with the results of agar dilution susceptibility testing for 18 antimicrobial agents against 324 strains of gram-positive and gram-negative bacteria, including 99 strains of staphylococci, 101 strains of antimicrobial-resistant gram-negative bacteria, 40 strains of enterococci, and 84 isolates of campylobacter jejuni. overall agreement of mics (+/- 1 log2 dilution) was 97.3% for staphylococci, 94.6% for gram-negative bacilli, and 100.0% for entero ... | 1992 | 1452709 |
| prevalence of bacterial agents of diarrhoeal disease at the national university hospital, singapore and their resistance to antimicrobial agents. | over a 50-month period, 4,508 stool specimens from patients with diarrhoea were bacteriologically examined at the national university hospital, singapore. salmonella serotypes other than the typhoid and paratyphoid bacilli were the most common finding, being isolated in 10.8% of cases. campylobacter jejuni was unexpectedly infrequent (1.9%); aeromonas hydrophila was found in 1.8%. no other aerobic pathogen occurred in more than 1% of cases. clostridium difficile was sought only when requested, a ... | 1992 | 1455527 |
| [sensitivity of the pathogen of campylobacter infection to various antibiotics]. | antibiotic sensitivity of 21 campylobacter strains isolated from humans, monkeys and birds with diarrhea was assayed and the findings are presented. it was shown that all the isolates were highly sensitive to ofloxacin, pefloxacin, ciprofloxacin, josamycin, pipemidinic acid and amoxyclav (a combination of amoxycillin and clavulanic acid). the predominating majority of the strains were resistant to rifampicin, amoxycillin and phosphomycin. the majority of the cultures were sensitive to erythromyc ... | 1992 | 1456823 |
| occurrence, removal and seasonal variation of "thermophilic" campylobacters in a sewage treatment plant in italy. | monitoring of "thermophilic" campylobacters in a sewage treatment plant in bologna (italy) has shown that incoming sewage contained a most probable number of 1630 campylobacters/100 ml. the secondary treatment in activated sludge tanks reduced 98.61% of campylobacters, 95.32% of fecal coliforms, 96.46% of fecal streptococci, 93.36% of salmonellas and 93.01% and 88.29% of bod5 and cod respectively. subsequent tertiary treatment with 3 ppm of chlorine dioxide for 15 min reduced 100% of campylobact ... | 1992 | 1457031 |

| structural studies of peptidoglycans in campylobacter species. | peptidoglycans (pg) from campylobacter coli, campylobacter jejuni, and campylobacter fetus were composed of muramic acid, glucosamine, alanine, glutamic acid, and diaminopimelic acid in a molar ratio of 1.1:1:1.7:1.1:09. thirty percent of the amino groups of diaminopimelic acid were involved in cross-linkages between peptides. during cultivation, c. coli and c. jejuni changed from a spiral to a coccoid form. in c. coli, we could isolate pg only from the spiral forms in yields of 0.8-1.2% by dry ... | 1992 | 1461153 |
| [diarrhea in cats]. | diarrhoea is regarded as the characteristic symptom of intestinal disturbances. however, cats with intestinal disturbances can also show other symptoms such as vomiting, increased or decreased appetite and loss of weight. cats with diarrhoea are usually only referred to the clinic if they have a chronic problem. acute diarrhoea reacts well to symptomatic treatment, but chronic diarrhoea requires a specific diagnosis for a directed therapy and prognosis. it is essential to examine faeces and bloo ... | 1992 | 1462341 |
| rapid emergence of quinolone resistance in campylobacter jejuni in patients treated with norfloxacin. | 15/60 subjects from one center, who all took part in a multicenter double-blind, placebo-controlled study to evaluate the effect of norfloxacin on acute enteritis, had norfloxacin sensitive strains of campylobacter jejuni in pre-study stool specimens. eight of the 15 subjects received active drug. in 3 of these 8, high-level quinolone resistant campylobacter strains of the same serotype as in pre-treatment samples were isolated 4-90 days after the initiation of treatment. | 1992 | 1465591 |

| campylobacter infections in calves, piglets, lambs and kids in trinidad. | faeces or rectal swabs from 689 diarrhoeic and non-diarrhoeic animals were cultured for thermophilic campylobacters and their antibiograms were determined. three hundred and fifteen (45.7%) samples were positive for campylobacter. piglets had the highest prevalence, 79.3% (233/294) and lambs, the lowest with 17.9% (15/84) being positive. the difference was statistically significant (p < or = 0.01; chi 2). in calves, 20.5% (60/293) and in kids 38.9% (7/18) were positive for campylobacters. the pr ... | 1992 | 1467924 |
| helicobacter (campylobacter) pylori in gastric brushing cytology. | helicobacter (formerly campylobacter) pylori is frequently associated with chronic gastritis and peptic ulcer and has been implicated as an etiologic agent. identification of h. pylori is important for specific treatment with antibiotics and bismuth compounds. we studied 27 patients who presented with symptoms of gastritis or peptic ulcer on whom paired gastric biopsies and gastric brushings for cytology had been performed. biopsies were stained with h & e and warthin-starry or giemsa for h. pyl ... | 1992 | 1468331 |
| erysipelas-like skin lesions associated with campylobacter jejuni septicemia in patients with hypogammaglobulinemia. | three cases are reported of hypogammaglobulinemic males with recurrent campylobacter jejuni septicemia and erysipelas-like cellulitis without diarrhoea. in one patient campylobacter jejuni grew from skin biopsy specimens. the findings in another patient were strongly suggestive of osteomyelitis caused by campylobacter jejuni. since the susceptibility of hypogammaglobulinemic patients to infection with campylobacter jejuni is probably related to a lack of serum bactericidal activity against campy ... | 1992 | 1468426 |

| helicobacter (aka campylobacter) pylori as the major causal factor in chronic hypochlorhydria. | helicobacter (formerly known as campylobacter) pylori, a recently discovered gastrointestinal bacterial pathogen, has been shown to be etiologic for type b or antral gastritis, and usually has chronic active pathological changes associated with its presence. acute helicobacter infection in most cases induces reduced stomach acid secretion which usually returns to normal levels of secretion after a few months. yet helicobacter gastritis has never been known to spontaneously remit after it has bee ... | 1992 | 1494326 |
