Colonisation of type D Pasteurella multocida was studied in five groups of seven SPF piglets each. Piglets of Group 1 were kept together with seven 5-week-old piglets obtained from a large herd infected with toxigenic P. multocida for 16 weeks (contact infection). These piglets were made free from toxigenic Bordetella bronchiseptica by local immunisation. Piglets of Group 2 were inoculated with 5 x 10(7) colony-forming units (cfu) of P. multocida washed from the nasal mucosa of piglets free from toxigenic B. bronchiseptica with fetal calf serum. Piglets of Group 3 were inoculated intranasally with 5 x 10(7) cfu of P. multocida washed from yeast-extract proteose-peptone cystine (YPC)-blood agar with fetal calf serum. Piglets of Group 4 were inoculated with 5 x 10(7) cfu of P. multocida grown in a YPC-based broth without blood. Piglets of Group 5 served as controls. The piglets of Group 1 did not contract P. multocida infection from infected contact piglets. After a single inoculation one of four, while after three inoculations two of three piglets of Group 2 became infected by P. multocida. After a single inoculation none of four, while after three inoculations one of three piglets of Group 3 were colonised by P. multocida. Both single and repeated inoculation failed in piglets of Group 4. 相似文献
