Serotype distribution of Campylobacter jejuni and Campylobacter coli isolated from hospitalized patients with diarrhea in central Australia.

Campylobacter jejuni and/or Campylobacter coli was cultured from 218 of 1,078 patients of all age groups admitted to Alice Springs Hospital, Alice Springs, central Australia, between July 1988 and June 1989 for treatment of diarrhea. One hundred sixty-six Campylobacter colonies from 127 patients were subjected to O serotyping by using the Penner typing scheme. All except 29 colonies could be serotyped. A total of 46 serotypes were identified, and the predominant serotypes were O:8, 17, O:22, O:1,44, and O:19. A large proportion of colonies reacted with more than one antiserum, and nine serotypes had antigenic compositions not observed previously. Several patients had multiple infections with more than one serotype, and some patients were shown for the first time to be infected with up to three different serotypes. Repeated reinfections with different serotypes were seen in some patients. In some patients, provided it was not due to reinfection with the same serotype, long-term excretion of the same serotype was seen, and for the first time, one patient showed evidence of excretion of the same serotype for up to 73 days.

Biotypes of Proteus rettgeri.

Examination of 729 isolates of Proteus rettgeri showed that 674 reacted positively in tests for phenylalanine deamination, indole production, growth on citrate, and acid production from meso-inositol, and negatively for L-ornithine decarboxylation and acid production from lactose, maltose, D-xylose, and L-arabinose. Only 51 isolates differed in one, and four differed in two of these ten reactions, which were taken as the core characteristics of the species. On the basis of additional tests (acid production from salicin, L-rhamnose, D-mannitol, adonitol, and D-arabitol), the 729 isolates could be separated into five groups. Goups 1, 2, 3, and 4 could be further separated on the basis of the reaction with meso-erythritol, and group 5 could be subdivided on the basis of reaction with D-mannitol. Two metabolically distinct kinds of P. rettgeri were recognized. Isolates of the first kind (groups 1, 2, 3, and 4) each utilized both adonitol and D-arabitol and most utilized meso-erythritol. Isolates of the other kind (group 5) were negative with the three polyhydric alcohols but resembled, in their reactions, some strains of Providencia stuartii. These may be intermediates between P. rettgeri that catabolize these substrates and the Providencia.
