An Attenuated Salmonella enterica Serovar Typhimurium Strain and Galacto-Oligosaccharides Accelerate Clearance of Salmonella Infections in Poultry through Modifications to the Gut Microbiome.

is estimated to cause one million foodborne illnesses in the United States every year. -contaminated poultry products are one of the major sources of salmonellosis. Given the critical role of the gut microbiota in transmission, a manipulation of the chicken intestinal microenvironment could prevent animal colonization by the pathogen.

A comparison of sequencing platforms and bioinformatics pipelines for compositional analysis of the gut microbiome.

Background: Advancements in Next Generation Sequencing (NGS) technologies regarding throughput, read length and accuracy had a major impact on microbiome research by significantly improving 16S rRNA amplicon sequencing. As rapid improvements in sequencing platforms and new data analysis pipelines are introduced, it is essential to evaluate their capabilities in specific applications. The aim of this study was to assess whether the same project-specific biological conclusions regarding microbiome composition could be reached using different sequencing platforms and bioinformatics pipelines.

The oral bacterial microbiome of occlusal surfaces in children and its association with diet and caries.

Dental caries is the most prevalent disease in humans globally. Efforts to control it have been invigorated by an increasing knowledge of the oral microbiome composition. This study aimed to evaluate the bacterial diversity in occlusal biofilms and its relationship with clinical surface diagnosis and dietary habits.

Genome Sequences of Potential Probiotic Isolates from Human Infants.

Probiotics provide health benefits to their hosts, including modulation of host immune response, inhibition of colonization by pathogens, modulation of the gut microbiota, and epithelial barrier enhancement. Here, we present the draft genome sequences of two newly isolated strains of probiotic potential from healthy human infants.

Canine bartonellosis: serological and molecular prevalence in Brazil and evidence of co-infection with Bartonella henselae and Bartonella vinsonii subsp. berkhoffii.

The purpose of this study was to determine the serological and molecular prevalence of Bartonella spp. infection in a sick dog population from Brazil. At the São Paulo State University Veterinary Teaching Hospital in Botucatu, 198 consecutive dogs with clinicopathological abnormalities consistent with tick-borne infections were sampled.
