SUMMARYDog faeces collected from a public park were cultured on selective media forCampylobacterspp.Campylobacter jejuniwas isolated from 12 (4·6%) of 260 specimens. In contrastSalmonellaspp. were found in only three (1·2%). Six of the 12 isolates were nalidixic acid-resistant thermophilic campylobacters (NARTC), whereas during the same period of study none were found among human isolates. Most of the campylobacter positive faeces were found during June and July. Dog faeces deposited in public places constitute only a small potential source of infection by this organism.

SUMMARYDuring November and December 1981 more than 50 residents in a village in Derbyshire had an acute gastrointestinal illness. One month later a second outbreak occurred affecting another 22 people. Campylobacter jejuni was isolated from 12 patients; no other gastrointestinal pathogens were identified. A casecontrol study showed an association with the consumption of unpasteurized milk from one particular farm. No new cases were identified for 6 months following the application of a Pasteurization Order from 26 January to 23 February 1982.

SUMMARYLiving flies collected from three locations were cultured on selective medium forCampylobacterspp.Campylobacter jejuniwas isolated from five (2·4%) of 210 flies examined.These results suggest that the potential hazard to health from the transmission of campylobacters from animals to human food by flies is small.
