Sixty-five draft genome sequences of Campylobacter coli and Campylobacter jejuni from table egg layer chickens. Microbiology Resource Announcements. 0:e00670-24. https://doi.org/10.1128/mra.00670-24. DOI: https://doi.org/10.1128/mra.00670-24 Interpretive Summary: Campylobacter coli and C. jejuni are very similar species to each other and are a leading cause of diarrheal disease in humans. A common source of infection of humans is from poultry meat products. Although vertical transmission through the egg from hen to broiler may occur, chicken eggs are not considered to be a common source of human infection. Egg layers are kept on the farm for much longer periods and are raised in very different environments from meat-type birds. Searches of National Center for Biotechnology Information databases and pubMLST databases produced no DNA sequences identified as being from Campylobacter from table-egg layers. Campylobacter isolates were collected from layer hens and their genomes were sequenced and the sequences were placed in public databases. Researchers will be able to use the sequences to determine if the strains found in layer chickens are distinct from isolates from broiler chickens. Technical Abstract: We present the draft genomic sequences of sixty-five isolates of Campylobacter spp. (38 C. coli and 27 C. jejuni) isolated from table egg-layer chickens, which are not generally associated with human transmission. Up to this time there are no publicly available genomic sequences of Campylobacter isolated from laying hens. |
