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.

A One Health approach based on genomics for enhancing the surveillance in Colombia.

Objectives: This study aimed to provide evidence of the domestic benefits of introducing an integrative genomic analysis from the One Health approach in the national surveillance of between 1997-2017 in Colombia.

Methods: Data on from clinical laboratory-based surveillance between 1997-2017 and from a national cross-sectional study at chicken retail stores in Colombia were compared using a phenotypic, molecular, and genomic approaches. Additional analysis by serovar using single nucleotide polymorphism was developed to increase the resolution of the relatedness between the interfaces.

Multidrug-resistant spp. in fecal samples of pigs with suspected salmonellosis in Antioquia, Colombia, 2019-2021.

Objectives: To determine the proportion of in fecal samples of live pigs with suspected salmonellosis analyzed at the diagnostic unit of the University of Antioquia, Colombia between 2019 and 2021, and examine the serotypes and antimicrobial resistance patterns.

Methods: This was a laboratory-based cross-sectional study of routine data on fecal samples received from pig farms in all nine subregions of Antioquia state, Colombia. spp.

Prevalence and antimicrobial resistance of and spp. in animal feed in Colombia.

Objective: To determine the prevalence and antimicrobial resistance of and spp. in animal feed samples collected between 2018 and 2021 in Colombia.

Methods: This was a laboratory-based cross-sectional study using routine data from the program for inspection, surveillance, and control of animal feed at the Colombian Agriculture Institute.

Development of a Phage Cocktail to Target Strains Associated with Swine.

Infections caused by multidrug resistant strains are problematic in swine and are entering human food chains. Bacteriophages (phages) could be used to complement or replace antibiotics to reduce infection within swine. Here, we extensively characterised six broad host range lytic phages, with the aim of developing a phage cocktail to prevent or treat infection.
