A strain from human diarrhea originally identified as Campylobacter mucosalis (NCTC 12408) was examined by using 64 phenotypic characters. The similarity of this strain to 297 isolates of Campylobacter, Helicobacter, Arcobacter, and related taxa was then determined with a computer-supported data analysis program, MVSP. NCTC 12408 showed closest similarity to 20 type, reference, and field isolates of Campylobacter concisus. These strains were clearly separated from those of C. mucosalis in the numerical analysis of phenotypic tests; a table was constructed from the data used to aid in differentiating these two species in the clinical laboratory. The identity of NCTC 12408 was confirmed as C. concisus by visual comparison of its sodium dodecyl sulfatepolyacrylamide gel whole-cell protein electrophoregram with those of type strains of C. concisus and C. mucosalis. These data suggest that genuine human infection with C. mucosalis has not yet been reported.

“…often was the only value reported. However, grouping all species of Campylobacter does not provide us with information for understanding human risk, as many species of Campylobacter (i.e., Campylobacter fetus, Campylobacter lanienae, and Campylobacter mucosalis) rarely infect humans (Figura et al, 1993;Levesque et al, 2016;Igwaran and Okoh, 2019). Within the studies included in the meta-analysis, a number of studies did not provide the information needed to adequately address the quality assessment questions, limiting our confidence in the results.…”

Campylobacter cause gastroenteritis in humans and may be shed in the feces of livestock and poultry species, including cattle, chicken, turkey, and swine. However, a synthesis of the prevalence on farms in the United States and Canada is currently lacking. Thus, our objective was to conduct a systematic review and metaanalysis to estimate the prevalence of Campylobacter coli, Campylobacter jejuni, and Campylobacter spp. on livestock and poultry farms operated under commercial conditions in the United States and Canada. The relevant literature was identified and examined for eligibility based on a priori inclusion and exclusion criteria. Relevant data were extracted, and a meta-analysis was performed. The data were transformed using the Freeman-Tukey arcsine transformation to stabilize the variance. A separate meta-analysis was performed for each animal species, level of sampling (individual versus pooled), and species of Campylobacter, for a total of 29 meta-analyses. C. jejuni and Campylobacter spp. were present in all livestock and poultry species of interest, whereas C. coli was found in all species of interest with the exception of chickens. Furthermore, substantial heterogeneity was observed in most meta-analyses. In an attempt to account for this, subgroup analyses were performed on potential moderators. However, with the exception of beef cattle, where studies in feedlot cattle reported a consistently higher prevalence compared with adult cattle on pasture, significant heterogeneity remained in the majority of meta-analyses after accounting for potential moderators. The results of this review can be used to inform future risk assessment, consumer and producer awareness, and resource allocation, and identify gaps for future research.

Aims: Campylobacter sp. are important causes of reproductive disease in ruminants worldwide. Although healthy bulls are well-known carriers for infection of cows, the role of rams as a potential source for infecting ewes is unclear. This study aimed to determine prevalence, species distribution, genetic diversity and antimicrobial susceptibility profiles of Campylobacter sp. isolated from the preputial cavity of healthy rams. Methods and Results: The material of this prospective study comprised 191 swab samples taken from the preputial cavity of healthy rams. Enrichment and membrane filtration were employed for the isolation of Campylobacter. Presumptive isolates were confirmed as Campylobacter by phenotypic and molecular tests. 16S rRNA gene sequence analysis was used for the definitive identification of the isolates at species level, and genotyping was performed using pulsed-field gel electrophoresis (PFGE). The susceptibility of the Campylobacter sp. isolates to various antibiotics was determined by the disk diffusion test. In all, 27 of the 191 (14Á13%) swab samples were found to be positive for Campylobacter sp. (28 isolates were recovered in total). Per phenotypic and genotypic analyses, one isolate was identified as Campylobacter mucosalis and the remaining 27 isolates were identified as Campylobacter sputorum bv. faecalis. The PFGE analysis of the C. sputorum biovar faecalis isolates produced 17 clusters and 24 different pulsotypes, indicating high genetic heterogeneity. All 28 isolates were found to be susceptible to all of the antibiotics tested. Conclusions: Healthy rams may be an important reservoir of different Campylobacter species in the preputium. Significance and Impact of the Study: This study demonstrated for the first time that healthy rams can carry different Campylobacter sp. including genetically diverse C. sputorum bv. faecalis and C. mucosalis in the preputial cavity. Further investigation on the potential implication of this finding on sheep reproductive health (e.g. infectious infertility, and abortion) and overall epidemiology of Campylobacter may be warranted.
