“…This is in agreement with the findings of Skirrow & Benjamin (1982) who found the frequency of C. coli in Britain to be between 3 and 5%. The predominance of Penner serotypes 2, 4 and 1 in the human isolates examined in this study has also been reported elsewhere both in Britain (Jones et al 1984) and North America (Karmali et al 1983;Penner et al 1983). All of the Penner strains isolated from the gulls were present in the human population.…”

During much of the present century, the population of herring gulls in Britain has increased rapidly (Cramp, Bourne & Saunders, 1973; Chabrzyk & Coulson, 1976; Monaghan & Coulson, 1977). Accompanying this changes was an increased utilization by these birds of human waste as a food supply, particularly sewage and refuse emanating from our towns and cities (Monaghan, 1983; Hortonet al.1983). This, coupled with their habits of roosting on agricultural land and water storage reservoirs and of breeding on inhabited buildings, has given rise to concern over the role of these birds in the spread of disease to man and domestic animals (e.g. Fenlon, 1981; Reillyet al.1981; Butterfieldet al.1983; Monaghanet al.1985; Girdwoodet al.1986).

“…Approximately 7 and 3°% respectively of organisms tested proved to be ungroupable by these two systems and in the Penner system up to 20% of the typable isolates reacted with more than one antiserum (Penner, Hennessy & Congi, 1983). Serological grouping of thermophilic Campylobacter species does not necessarily indicate a definite identity among isolates of the same serogroup (Karmali et al 1983). The identification of a large number of BRENDA types among the intestinal thermophilic Campylobacter species is not therefore surprising.…”

SUMMARYIntestinal thermophilic Campylobacter species produce stable patterns when subjected to bacterial restriction endonuclease DNA analysis (BRENDA); this technique is therefore of considerable value in epidemiological studies. BRENDA was used to examine thermophilic Campylobacter species from humans, wild and domestic animals. One hundred and ninety-four (61 %) of 316 isolates of Campylobacter jejuni from humans had BRENDA patterns which could be matched to those of animal isolates. Poultry appear to be a major source of infection for C. jejuni in humans with nearly half (49 7 %) of the human isolates giving patterns which were indistinguishable from those isolated from poultry. A total of 60 BRENDA types were identified from 316 human isolates and 11 of these had the same pattern as those isolated from poultry. One of the three Campylobacter coli BRENDA types recovered from poultry was indistinguishable from a human isolate type. Pigs appear to be only a minor source of C. coli infection for humans in New Zealand. Rats were found to be infected with strains of C. jejuni with BRENDA patterns indistinguishable from those infecting humans, poultry and a horse. None of the 102 isolates of Campylobacter species from wild birds gave BRENDA patterns similar to those of isolates from humans.

“…In contrast, the predominant LG genotype of strains belonging to the HS-4 complex serogroup was only found in 38% of the strains tested. Penner serogroups 1, 2, 3, and especially 4, which together comprise a large proportion of clinical isolates in certain parts of the world, are not clonal but represent a genetically diverse population (2,13,14,19,27,32). In this respect, the strong correlation between LG genotype and HS-1, HS-2, and HS-3 serotype is remarkable.…”

Development and Application of a New Scheme for Typing Campylobacter jejuni and Campylobacter coli by PCR-Based Restriction Fragment Length Polymorphism Analysis

A molecular typing approach for Campylobacter jejuni and Campylobacter coli was developed with restriction fragment length polymorphism analysis of a 9.6-kb PCR-amplified portion of the lipopolysaccharide gene cluster. Sixty-one Penner serotype reference strains were analyzed with this new genotyping scheme, and 32 genogroups were found. Eleven additional genogroups were obtained from 87 clinical C. jejuni strains tested. This molecular typing method shows a correlation with the Penner heat-stable serotyping method, a phenotypic typing method based on lipopolysaccharide structures that is often used as a "gold standard" for subtyping Campylobacter spp. This strong correlation suggests that the data obtained can be directly compared with epidemiological data collected in the past by classical serotyping of C. jejuni and C. coli. In contrast to the high percentage of nontypeability by phenotyping, this molecular typing method results in 100% typeability and provides a superior alternative to serotyping.
