“…and could infect 85 per cent of piglets with during initial four weeks of life. Alter et al, (2005) also found similar results where they found incidence of 56.6 per cent at fourth week and genotypic similarities was found between sow and piglets. Other probable sources can be from the boar which was positive and piglets were shifted into its pen after weaning as well as from piglets which was positive initially.…”

“…seems to be a natural inhabitant in pigs as they typically are colonized with Campylobacter spp. at a young age and their prevalence in herds is high (Weijtens et al, 1993;Alter et al, 2005;Boes et al, 2005), which also implies that the complete avoidance of Campylobacter spp. in pigs is difficult.…”

“…were shed in rectal samples by all the 48 slaughter pigs in this study, and more than 90% of the intestinal samples were positive throughout the 1-to 2-week study period, which is similar to previous findings of high occurrences of Campylobacter spp. in slaughter pigs (Alter et al, 2005;Boes et al, 2005;Anonymous, 2009). However, the number of Campylobacter spp.…”

This study aimed to assess whether inclusion of chicory or lupine (prebiotics) in the diet of pre-slaughter pigs for just 1 or 2 weeks could change the composition of their intestinal microbiota, stimulate the growth of bifidobacteria and help to lower the amount of thermoplilicCampylobacterspp. (mainlyCampylobacter jejuniandCampylobacter coli), which are a major cause of food-borne infections in humans. A total of 48 pigs that had an initial live weight of 90 kg were fed with either a lupine (organic concentrate with 25% blue lupine seeds), chicory (organic concentrate with 10% dried chicory roots) or control (100% organic concentrate) diet for 1 week (24 pigs) or 2 weeks (24 pigs) before slaughter. TheCampylobacterspp. level in rectal faecal samples after 0, 1 and 2 weeks of feeding and in the luminal content from ileum, caecum and colon at slaughter was determined by direct plating on modified charcoal-cefoperazone-deoxycholate agar plates. DNA extracted from the luminal content of distal ileum and caecum was used for terminal restriction fragment length polymorphism (T-RFLP) analysis of the composition of intestinal microbiota and for measuring the amount of bifidobacterial and total bacterial DNA by quantitative real-time PCR (qPCR).Campylobacterspp. were excreted by all pigs and present in the luminal content from distal ileum to midway colon with particularly high numbers in the caecum, but the excretion was reduced by 10-fold in pigs fed lupines for 1 week as compared with control- and chicory-fed pigs (mean log102.9v. 4.1 CFU/g;P< 0.05). The qPCR analysis showed that feeding with lupines resulted in higher levels of bifidobacteria in caecum as compared with the other diets (P< 0.05). T-RFLP analysis showed that four of the most abundant bacteria with terminal restriction fragment values >5% relative to the intensity of total abundance differed between the feed treatments (P< 0.05). Therefore, this study showed that even a short-term alternative feeding strategy with prebiotics in the diet of pre-slaughter pigs elicited changes in the composition of the intestinal microbiota, where lupine increased the level of bifidobacteria in caecum and reduced theCampylobacterspp. excretion level after 1 week.

“…C. coli was able to persist in pigs and in the environment in both production systems with different swine-rearing practices. The C. coli prevalence of sows and piglets at farrowing (ABF, 41.3%; conventional, 48.1%) suggests an early colonization of piglets (3,38) and potential transmission from sows. It is also important to highlight that the prevalence in piglets could potentially indicate the role of the environment in pathogen transmission.…”

The objectives of this study were to compare and characterize the prevalence of antimicrobial-resistant (AR) Campylobacter in conventional and antimicrobial-free (ABF) production systems on farms, at slaughter, and in the environment. Fecal and environmental samples were collected from ABF farms (pigs, 1,239; environment, 797) and conventional farms (pigs, 1,650; environment, 1,325). At slaughter, we collected samples from carcasses, including postevisceration swabs, postchill swabs, and mesenteric lymph nodes from ABF systems (postevisceration swabs, 182; postchill swabs, 199; mesenteric lymph nodes, 184) and conventional systems (postevisceration swabs, 272; postchill swabs, 271; mesenteric lymph nodes, 255) at separate processing facilities. We also sampled the processing plant environment, including truck and lairage floor swab samples (ABF, 115; conventional, 90). Overall, a total of 2,908 Campylobacter isolates, including Campylobacter coli (farm, 2,557, 99.8%; slaughter, 341, 98.3%) and Campylobacter jejuni (farm, 4, 0.2%; slaughter, 6, 1.7%), were isolated in the study. There was no significant difference in the prevalence of Campylobacter between ABF and conventionally raised pigs (farrowing, P ‫؍‬ 0.20; nursery, P ‫؍‬ 0.06; finishing, P ‫؍‬ 0.24) and the environment (P ‫؍‬ 0.37). At slaughter, Campylobacter was isolated from all of the stages, including postchill. The highest frequencies of resistance were exhibited against tetracycline (ABF, 48.2%; conventional, 88.3%). Ciprofloxacin-resistant C. coli isolates were observed in conventionally raised (17.1%) and ABF (1.2%) pigs (P ‫؍‬ 0.11). Antimicrobial use data from conventional farms indicated significant associations between oxytetracycline use and tetracycline resistance in the nursery pigs (P ‫؍‬ 0.01), between tiamulin exposure and azithromycin and erythromycin resistance in nursery (P < 0.01) and finishing (P < 0.01) pigs, and between enrofloxacin exposure and ciprofloxacin and nalidixic acid resistance in farrowing (P < 0.01) and nursery (P < 0.01) pigs. Identical antimicrobial resistance profiles were observed in the pigs and their environments on farms and at slaughter. In summary, our results highlight the persistence and dissemination of AR Campylobacter from farm to slaughter in ABF and conventionally raised pigs and their environments.
