Article Abstract
Tracking sources of contamination is an issue related to food safety. In a preliminary study conducted to evaluate the distribution of thermophilic Campylobacter in the environment surrounding dairy cattle and swine production, a number of Campylobacter lanienae were directly detected by PCR. The amplicons came from dairy cows and pig fecal samples, as well as from stored manure. DNA sequencing of a 360-bp fragment of C. lanienae 16S rRNA gene was performed. Alignment of sequences confirmed the bacterial identification as sequences shared 99-100% homology with C. lanienae 16S rRNA gene sequences available in GenBank. Interestingly, bioinformatics analyses also revealed two different genetic clusters depending on the animal reservoir. More samples and other molecular techniques need to be tested in order to characterize and evaluate the distribution of this microorganism in the agri-food chain.

In a previous study characterizing strains deficient in selenium metabolism, 50 strains were found to be similar to, but distinct from, the selenonegative species . Initial characterization based on multilocus sequence typing and the phylogeny of a set of 20 core genes determined that these strains form three putative taxa within the selenonegative cluster. A polyphasic study was undertaken here to further clarify their taxonomic position within the genus.

During the 2021 European Food Safety Authority coordinated harmonized monitoring of antimicrobial resistance in species in Slovenia, five -like strains were cultured from caeca of a total of 104 domestic pigs that could not be identified using the standard-prescribed biochemical tests or MALDI-TOF MS. The isolates were obtained using the standard ISO 10272 procedure for the isolation of thermotolerant with prolonged cultivation time. Small -like colonies were observed on mCCDA and CASA agar plates after 2-4 days of incubation; dark-field microscopy revealed relatively big spirilli-shaped bacteria exhibiting characteristic -like motility.

Article Synopsis
- Campylobacteriosis is a public health issue mainly caused by Campylobacter jejuni and Campylobacter coli, but there is growing awareness of other species like Arcobacter; however, little is known about Arcobacter in wild boars.
- A study examined fecal samples from 76 wild boars in Italy using various isolation techniques, finding that over half of the animals carried Campylobacter or Arcobacter, with Campylobacter lanienae being the most common.
- Almost 40% of the boars had high levels of Campylobacter in their feces, raising concerns about potential meat contamination, especially since these animals were hunted for consumption.

Campylobacter is a foodborne pathogen that could be isolated from various types of livestock, including small ruminant. The objectives of the current study were to investigate the prevalence of Campylobacter spp. in goats reared in the south of Thailand and identify the risk factors associated with Campylobacter infection of goat in Thailand.
