The aims of this study were to investigate the prevalence of
campylobacteria including Campylobacter jejuni subsp.
jejuni (C. jejuni) and Campylobacter
coli in human clinical samples and in samples from healthy
individuals and to reevaluate the efficacies of conventional selective
methods for isolation of Campylobacter spp. Two
charcoal-based selective media, modified charcoal cefoperazone deoxycholate agar (mCCDA) and cefoperazone-amphotericin-teicoplanin (CAT) agar, were compared with Skirrow's blood-based medium and with a
filter method (filter) applied to a yeast-enriched blood agar. A total
of 1,376 specimens were tested on all four media, and the percentages
of thermophilic Campylobacter-positive specimens isolated
on Skirrow's medium, filters, CAT agar, and mCCDA were 82, 83, 85, and
95%, respectively. When additional samples were processed with the
three selective media, mCCDA recovered significantly more thermophilic
Campylobacter spp. than Skirrow's medium
(P = 0.0034). No significant difference between
Skirrow's medium and CAT agar was observed in this study. Another six
taxa were identified, namely, Campylobacter concisus,
Campylobacter curvus-like bacteria, Arcobacter
butzleri, Arcobacter cryaerophilus,
Helicobacter cinaedi, and Sutterella
wadsworthensis. Most of these strains were isolated after 5 to 6 days of incubation by use of the filter technique. This paper provides
evidence for the existence of S. wadsworthensis in human
feces from clinical cases of gastrointestinal disorders and in feces
from a healthy individual. Furthermore, C. concisus was
isolated from a large number of diarrheal cases, particularly those at
the extremes of age, but was additionally isolated from the feces of
healthy people. Further investigations to establish the role of
C. concisus and S. wadsworthensis in enteric
disease is needed. We conclude that a range of campylobacteria may
cause infections in Denmark.
