Abstract
Pooled faeces samples from 106 poultry flocks in Norway were examined. Campylobacter fetus subsp. jejuni was isolated from 10 of 100 chicken flocks and from 4 of 6 turkey flocks. Eight of the 14 isolates were classified as biotype C. jejuni, which is frequently associated with human campylobacteriosis. Five strains belonged to the biotype C. coli. One strain was resistant to nalidixic acid but differed from the biotype NARTC in its ability to hydrolyse hippurate. The results indicate that C. fetus subsp. jejuni is widespread among Norwegian poultry.
Keywords: Campylobacter fetus subsp. jejuni, poultry, Norway
Sammendrag
Samleprøver av faeces fra 106 fjørfebesetninger ble undersøkt. Campylobacter fetus subsp. jejuni ble isolert fra 10 av 100 besetninger med høns og broilere, og fra 4 av 6 kalkunbesetnimger. Åtte av de 14 stammene som ble funnet tilhørte biotype C. jejuni som hyppig iso-leres i forbindelse med Campylobacter-enteritt hos mennesker. Fem stammer tilhørte biotypen C. coli. En stamme var Nalidixan-resistent, men adskilte seg fra biotypen NARTC ved evnen til å hydrolysere hip-p-urat. Resultatene indikerer at G. fetus subsp. jejuni er vanlig blant norske fjørfe.
