| Abstract | ||
| Isolation and identification of Ornithobacterium rhinotracheale (ORT) from infertile eggs, dead embryos, dead in shell chicks and turkeys as well as day-old chicks and turkey poults obtained from native hatcheries suffering from increased embryonic mortality, dead in shell birds and high mortality in newly hatched chicks and turkey poults was undertaken for the first time. Salmonella give (S. give could also be concomitantly isolated in certain occasions. Pathogenicity testing of the isolated ORT and/or give was investigated in 3 day-old chicks. The clinicopathological picture in experimentally infected chicks was described. | ||
