We developed and studied a molecular typing approach for Campylobacter spp. with restriction fragment length polymorphism (RFLP) analysis of the flagellin gene flaA in C. jejuni. Using polymerase chain reaction, we amplified the flaA gene from strains comprising different HL:O serotypes by using a primer set directed at the conserved 5' and 3' flaA gene(More)
Campylobacter jejuni is the most common enteric pathogen isolated from university and college students in the United States. During the fall and winter quarters of the 1983-1984 academic year, the authors conducted a case-control study at the University of Georgia, Athens, Georgia, to identify risk factors for C. jejuni enteritis. Students with diarrhea(More)
Seventy-eight aerotolerant Campylobacter isolates were characterized phenotypically and by DNA hybridization (hydroxyapatite method at 50 and 65 degrees C). Two DNA relatedness groups were found. (i) Sixty-four strains belonged to aerotolerant Campylobacter DNA hybridization group 2. These organisms were isolated from humans, primarily with diarrheal(More)
By DNA-DNA hybridization, we classified 26 human strains, 4 dog and cat strains, and 4 hamster strains putatively identified as Helicobacter cinaedi as well as 2 human strains and 2 animal strains of Helicobacter fennelliae. All but one human strain belonged to the same hybridization group as the type strain of H. cinaedi. The animal strains also appeared(More)
To determine whether extraintestinal isolates of Campylobacter jejuni and Campylobacter coli are the consequence of unusual host or bacterial characteristics, we studied clinical and bacteriologic features of 24 extraintestinal infections. Common serotypes and auxotypes were present among the extraintestinal isolates. Gastrointestinal isolates were more(More)
Pontiac fever, a unique epidemiologic form of legionellosis, is characterized by a short (one- to two-day) incubation period and a self-limited grippe-like illness without pneumonia. In 1968, the first documented outbreak of this syndrome affected persons who had entered a health department building in Pontiac, Michigan. Epidemiologic analyses clearly(More)
In May 1983, an estimated 865 cases of epidemic gastrointestinal disease occurred in Greenville, Florida. Surveillance of pharmacy sales of antidiarrheal medicines suggested that the outbreak was confined to Greenville and its immediate vicinity. Surveys demonstrated that the gastrointestinal illness attack rates inside and outside the city limits were 56(More)
A total of 593 strains of thermophilic Campylobacter species were isolated either from humans with diarrhea or from poultry in King County, Washington. Of these strains, 98 (52 hippurate-positive strains and all 46 of the hippurate-negative strains) were selected for further phenotypic characterization and genetic classification. Hippurate hydrolysis, the(More)
Campylobacter laridis, a recently described thermophilic Campylobacter species found principally in seagulls, has not previously been linked to illness in humans. Six clinical isolates of this species were referred to the national campylobacter reference laboratory in 1982 and 1983. Each isolate was confirmed by biochemical characterization and by DNA(More)
