To the problem of Campylobacter jejuni detectability in water.
In a series of model experiments two isolation procedures for the detection of water-borne Campylobacter jejuni were compared: a standard culture in thioglycolate broth enriched with 7% defibrinated sheep blood and supplement C and a modified membrane filtration method in which the filter (porosity 0.45 microns) plated on campylobacter agar surface was removed after the first 24 hours of incubation and the plate further incubated for 48 hours. The recovery rates by the thioglycolate broth method were markedly less pronounced than those obtained by the modification of membrane filtration technique, especially in the case of water rich in organics. The best isolation parameters were achieved with water samples of at least 10 ml in volume.
