متن کاملRisk of Salmonella transmission via cryopreserved semen in turkey flocks.
To investigate the possibility to carry pathogen bacteria in turkey flocks via cryopreserved semen, research was carried out 1) to investigate the microbial contamination of fresh and frozen thawed turkey semen and 2) to evaluate the effect of the freezing-thawing process on the survival of 3 serovars of Salmonella spp. experimentally inoculated in turkey semen. Five pools of semen diluted 4-fo...

Recent studies suggest that the organism is highly prevalent in poultry semen and may contribute to vertical transmission between the breeder hen and offspring. Because Campylobacter requires iron for its growth and survival, the objective of this study was to determine if the addition of natural and ...
