2.3.3. Isolation of Campylobacter spp.
The Park Sanders broths were enriched for 4 h at
32C, and 2 ml reconstituted Supplement B added (Mast
Diagnostics). The broths were incubated at 37C for 2 h,
and then moved to 42C for 40–42 h. After incubation,
colonies were streaked onto mCCDA (Oxoid) plates
containing selective supplement SR155E (Oxoid) and
nutritive blood gelatine plates (4.75 g beef extract (Oxoid),
4.75 g bacteriological peptone (Oxoid), 2.38 g sodium
chloride (Sigma), 6.40 g agar technical (Oxoid),
475 ml distilled water – sterilised by autoclaving at
121C for 15 min, 1 vial SR084 supplement (Oxoid) and
25 ml lysed horse blood (Oxoid) added prior to pouring).
Plates were incubated for 48 h at 37C and 2–5 d
at 42C, respectively, under the Campygen gas system
(Oxoid). Suspect colonies were confirmed by catalase,
oxidase, Gram staining and negative growth at 25C.
