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 ...19921457031
listeria spp. and enteric pathogens in raw meat: a survey in the ferrara area.the authors report the results of a study performed on 113 samples of raw meat of 6 different animal species in order to evaluate the extent of contamination by some organisms responsible for food-borne infections. a total of 2 strains of salmonella (1.7%), 36 of yersinia (31.8%), 35 of campylobacter (30.9%) and 13 of listeria (11.5%) were isolated. the possible role of contaminated meat in cases of human listeriosis is pointed out.19892491284
ecological survey of listeria in the ferrara area (northern italy).a bacteriological survey was done on human and environmental specimens from the province of ferrara in northern italy to determine the prevalence of listeria spp. because no cases of listeriosis so far had been reported. ten strains of listeria spp. (1.9%) (7 l. monocytogenes, 3 l. innocua) were detected in 513 faecal specimens from asymptomatic humans, whereas none was recovered from 505 vaginal swabs of fertile women with discharges. thirteen strains (9 l. monocytogenes, 4 l. innocua) were det ...19883143192
[isolation in the ferrara province of campylobacter thermophile from man, animals, food and the environment during the 2-year period 1984-1985].during a two-years period (1984-1985), thermophilic campylobacters were sought in materials of various origin: isolation rates were as follows: from 1680 stool specimens of enteropathic patients, 6.0%; from 1920 stool specimens of asymptomatic subjects, 0.5%; from 325 stool specimens of healthy animals, belonging to 5 different species, 51.7%; from 106 meat samples of 6 different species, 32.1%; from 194 samples of raw milk, 0.5%; from 43 samples of surface waters, 37.2%; from 150 samples of was ...19883223996
campylobacter jejuni infection and guillain-barré syndrome: a case-control study. emilia-romagna study group on clinical and epidemiological problems in neurology.we performed a case-control study to investigate the association between campylobacter jejuni (cj) infection and guillain-barr| syndrome (gbs) or miller-fisher syndrome. we compared 60 cases with 109 hospital controls matched for age, gender, hospital and geographical location. to diagnose the cj infection, we considered the association between serologic positivity for cj and a previous diarrheal illness within 3 months of inclusion in the study. fifteen percent of cases versus 5% of hospital co ...19989890808
