SalmoFree Phage Additive Proves Its Safety for Laying Hens.

Background: The avian pathogen Gallinarum causes avian typhosis in laying hens, leading to high mortality rates among adult birds, which poses a significant problem in the poultry industry. Various products, such as vaccines, antibiotics, probiotics, and disinfectants, are commonly used to prevent and control the disease on farms. An alternative to these products is the use of bacteriophages, which may effectively prevent the colonization of Gallinarum.

Mucin-induced surface dispersal of and via quorum-sensing dependent and independent mechanisms.

Unlabelled: Nasopharyngeal carriage of staphylococci spreads potentially pathogenic strains into (peri)oral regions and increases the chance of cross-infections. Some laboratory strains can also move rapidly on hydrated agar surfaces, but the biological relevance of these observations is not clear. Using soft-agar [0.

Anaerobiosis, a neglected factor in phage-bacteria interactions.

Many parameters affect phage-bacteria interaction. Some of these parameters depend on the environment in which the bacteria are present. Anaerobiosis effect on phage infection in facultative anaerobic bacteria has not yet been studied.
