Bacteriophages as an alternative for biological control of biofilm-forming .

Salmonellosis is one of the most common foodborne diseases worldwide. Surface adherence and biofilm formation are among the main strategies evolved by to survive under harsh conditions and are risk factors for its spread through the food chain. Owing to the increase in antimicrobial resistance, there is a growing need to develop other methods to control foodborne pathogens, and bacteriophages have been suggested as a potential alternative for this purpose.

Characterization of novel of temperate phages of Staphylococcus aureus isolated from bovine milk.

Bovine mastitis is an important disease in dairy cows, and Staphylococcus aureus is the most prevalent microorganism. Bacteriophages are considered an alternative to treat bacterial infections due to antimicrobial resistance crisis. In this study, we isolated and characterized novel S.

Genomic characterization of multidrug-resistant Salmonella Heidelberg E2 strain isolated from chicken carcass in southern Brazil.

Salmonella Heidelberg is a clinically-important serovar linked to food-borne illness, and commonly isolated from poultry products. Since 1962, Salmonella Heidelberg has been widely reported from poultry production systems in several countries, including Brazil. The emergence of multidrug-resistant (MDR) Salmonella Heidelberg strains in food animals underscores a significant food safety hazard.

Surface conditioning with bacteriophages reduces biofilm formation of Heidelberg.

remains one of the most common foodborne pathogens worldwide, and its resistance to antimicrobials has increased considerably over the years. In this context, was evaluated the action of three bacteriophages isolated or combined in inhibiting the adhesion and removal of Heidelberg biofilm on a polystyrene surface. The bacteriophages UPF_BP1, UPF_BP2, UPF_BP3 and a pool of them were used for biocontrol of Heidelberg biofilms on polystyrene surface in the action times of 3, 6 and 9 h.

Effect of two lytic bacteriophages against multidrug-resistant and biofilm-forming Gallinarum from poultry.

1.  Gallinarum (SG) infections cause fowl typhoid, which leads to important economic losses. Multidrug resistance (MDR) and the capacity for bacteria to form biofilms could play an important role in the persistence of SG in poultry flocks resulting in intermittent disease outbreaks.
