Kurthia gibsonii, a novel opportunistic pathogen in poultry
Kurthia gibsonii (H. Kurth, 1883) was isolated on 10 unrelated laying hen farms over a period of 15 months. Farmers reported elevated morbidity and mortality rates, and suspected of colibacillosis based on the necropsy findings. The most frequently found lesions were perihepatitis, fibrinous peritonitis, salpingitis and oophoritis. Necropsy findings and bacteriological results allowed the diagnosis of colibacillosis. In addition, K. gibsonii was isolated from the ovarian follicles (44.44 %), liver (22.22%), peritoneum (16.67%), bone marrow (5.56%), spleen (5.56%), and duodenum (5.56%). On all farms, coinfection with E. coli was detected, while on some farms other common avian pathogens were found as well. In total, 18 K. gibsonii strains were identified and phylogenetically analysed based on the 16S rRNA gene sequences. The results showed some variability of the strains originating from the same farm, although the overall phylogenetic diversity was low, regardless of the geographical location of the farm, age of the flock or date of collection. Embryo lethality assay showed K. gibsonii is not able to cause a primary infection. We conclude that Kurthia gibsonii may play a role as an opportunistic pathogen for poultry. This is the first report of coinfection of Kurthia gibsonii and E. coli in laying hens.
