285-291

Infections with Campylobacter spp. occur as a result of consumption of live cells with food. In developing countries those infections are immensely common, particularly during early childhood and 5 to 10 cases can appear during the initial two years of life. The symptoms appear usually after 1-7 days from infection depending on the number of ingested cells and individual sensitivity. Characteristic symptoms of infections caused by Campylobacter spp. infrequently occurring jointly in the clinical form of the disease include: diarrhea, abdominal pain and increased temperature. In the majority of cases the disease is mild and lasts from 2 to 7 days. Usually Campylobacter are excreted with feces during a period of 7-21 days, sometimes even longer. Occasionally in the increased risk group dangerous complications may occur. They include: bacteremia, meningo-myelitis, neurological disturbances and reactive arthritis.

nr 1

Forty-three C.f.s.f. strains and 19 C. jejuni strains from miscarried sheep foetuses and rectal mucosa smears were isolated. The C.f.s.f. strains were used to prepare 4 vaccines. The dynamics of the occurrence of antibodies against anti-Campylobacter in the sheep immunized with these vaccines was similar. The highest mean titres were found from experimental weeks 8 to 10. The vaccine applied in disease focus revealed satisfactory protective properties. The results obtained made it possible to select the strains which can be used for immunization of sheep.
