Among the 23 Salmonella strains isolated from 21 diseased chicken and 2 embryonated eggs in 6 poultry farms near Lusaka City in Zambia, serovars identified were S. Gallinarum (11 strains), S. Agona (7 strains), S. Alamo (1 strain), S. Infantis (1 strain), S. Virginia (1 strain), S. Haifa (1 strain), and S. Dublin (1 strain). S Gallinarum was detected at the highest incidence and from all the poultry farms. Fourteen serovars have been reported for the chickens in Zambia so far. Three serovars (S. Alamo, S. Haifa, S. Virginia) were newly identified in this study.

Post-weaning diarrhea (PWD) is a major concern for pig producers, as stress and early weaning increase susceptibility to enteropathogens like enterotoxigenic Escherichia coli (ETEC) and Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium).

The purpose of this study was to investigate the effects of thyme oil (TO), chitosan nanoparticles (CS-NPs), and TO-loaded-CS-NPs on controlling Salmonella Typhimurium (S. Typhimurium) infection in broiler chickens when compared to ciprofloxacin (Cip) antibiotic treatment. The CS-NPs and TO-loaded-CS-NPs were initially characterized using a transmission electron microscope.

Microplastics (MP), plastic particles <5 mm, are of global concern due to their worldwide distribution and potential repercussions on ecosystems and human well-being. In this study, MP were collected from the urbanized Susurluk basin in Türkiye to evaluate their vector function for bacterial biofilms, both in the wet and dry seasons. Bacterial biofilms were predominantly found on polyethylene (PE), polypropylene (PP), and polystyrene (PS), which constitute the most common MP types in the region.

Pullorum disease (PD) is a widespread disease that causes significant economic losses within the poultry industry of developing countries. An effective strategy for its prevention and control involves the implementation of decontamination procedures utilizing highly specific on-site detection techniques. In this study, a single-nucleotide polymorphism (SNP) site within the group_17537 gene of Salmonella enterica serovar Gallinarum biovars Pullorum (S.
