“…The isolation of C. jejuni (75%) and C. coli (16%) in this study has important implications for public health as C. jejuni is the species of Campylobacter most commonly involved in human Campylobacteriosis (Tauxe et al. 1987; Baffone et al. 1995; Nielsen et al.…”

Campylobacter species have been identified as the major cause of acute bacterial enteritis in the U.K. It has been suggested that the role of sheep in the epidemiology of Campylobacter has been underestimated. The aim of the present study was to determine the prevalence of Campylobacter in sheep sent for slaughter into an abattoir in Scotland and the prevalence of Campylobacter on the carcasses as a potential risk for human campylobacteriosis. Fecal samples and swabs (from fleeces and carcasses) were collected and processed using standard laboratory methods. The prevalence of Campylobacter obtained was unexpectedly high (49% positives from fecal samples by direct plating; 64% from fecal samples after enrichment; 95% from the fleeces after enrichment and 90% from the carcasses after enrichment) in comparison with the prevalence reported in the literature. It is the first time that such higher prevalence have been reported for Campylobacter isolated from sheep. The results showed that Campylobacter jejuni accounted for 75% of all the positive samples, followed by C. coli (16%), C. upsaliensis (2.52%), C. fetus (1.26%) and Arcobacter cryaerophilus (0.84%). These findings have important implications for public health as C. jejuni is the species of Campylobacter most commonly involved in human campylobacteriosis. PRACTICAL APPLICATIONS Campylobacter spp. isolates obtained during the study were preserved and are available to be used for further analysis. In fact, there has been some interest to use these isolates for multilocus sequence typing analysis. Epidemiological data regarding selected risk factors and the presence of Campylobacter in sheep and sheep carcasses was also obtained and analyzed during this study. The results from the epidemiological analysis are presented in a separate scientific paper including recommendations for the control of Campylobacter on sheep carcasses. The unexpected higher prevalence of Campylobacter in sheep found in this project might serve as motivation for future research studies. Furthermore, the methods used for isolation and identification of Campylobacter from sheep might be applicable to other animal species and/or other sources of Campylobacter.

Aims: To determine the prevalence of Campylobacter in surface waters of a highly populated Mediterranean area. Methods and Results: Surface water and wastewater samples were collected from an area in the north‐east of Spain during a 2‐year study. All the samples were analysed using the MPN method and Multiplex PCR to quantify and identify Campylobacter. It was detected in 82% of the samples from the Llobregat River with a mean of 1·3 MPN 100 ml−1. The lowest counts were obtained in summer. Campylobacter coli was the predominant species in this river. The bacteria were isolated from marsh water but not from seawater samples. The highest counts of campylobacters were found in poultry wastewater where Camp. jejuni was the predominant species, as in urban sewage. In pig slurry, Camp. coli was the only species detected. Conclusions: Campylobacter jejuni and Camp. coli are present and widely distributed in the surface water of the studied area. The two species co‐exist, with Camp. coli being predominant. In river water, campylobacter counts presented a seasonal distribution. No relationship with faecal indicators was found. Significance and Impact of the Study: This study provides the first data on the occurrence and concentrations of thermotolerant campylobacter species in surface water in a Mediterranean area.

“…These studies have demonstrated campylobacter carriage rates peaking in late spring and summer in broiler chicken flocks ( 10 , 11 ) and dairy cattle ( 12 ) but more constant infection in lambs and beef cattle ( 12 , 13 ). Campylobacter has been successfully isolated and cultured from surface water in Finland ( 14 , 15 ), Italy ( 16 ), and NW England ( 17 ), and sporadic campylobacteriosis (illness not associated with an outbreak) has been linked with exposure to untreated water in Scandinavia ( 18 , 19 ). C. jejuni has also been isolated from a wide range of animal and environmental samples in a rural area in NW England, which suggests a potential environmental risk for exposure ( 20 ).…”
