May 19, 2017  · The ST313 sequence type of Salmonella enterica serovar Typhimurium causes invasive non-typhoidal salmonellosis amongst immunocompromised people in sub-Saharan Africa (sSA). Previously, two distinct phylogenetic lineages of ST313 have been described which have rarely been found outside sSA. Following the introduction of routine whole genome sequencing of Salmonella.

The present study evaluated anti-diarrheal effects of a mixture of Coptidis rhizoma, Lonicerae flos, and Paeonia japonica (1:1:1, v/v/v) methanol extracts and dioctahedral smectite (CLPD) on piglet diarrhea caused by Escherichia coli (E. coli) and Salmonella typhimurium (S. typhimurium).

The gut microbiota confers resistance to pathogens of the intestinal ecosystem, yet the dynamics of pathogen-microbiome interactions and the metabolites involved in this process remain largely unknown. Here, we use gnotobiotic mice infected with the virulent pathogen Salmonella enterica serovar Typhimurium or the opportunistic pathogen Candida albicans in combination with metagenomics and.

Nontyphoidal Salmonella (NTS), particularly Salmonella enterica serovar Typhimurium, is among the leading etiologic agents of bacterial enterocolitis globally and a well-characterized cause of invasive disease (iNTS) in sub-Saharan Africa. In contrast, S. Typhimurium is poorly defined in Southeast Asia, a known hot spot for zoonotic disease with a recently described burden of iNTS disease.

To further elucidate the molecular and cellular mechanisms in the pathogenesis of PNAC, in the present study we combine genetic, molecular, and pharmacological approaches to demonstrate an essential.

Taken together, this finding constitutes a functional proof that MCR-4 proceeds in a distinct evolutionary path to fulfill a consistent molecular mechanism, resulting in phenotypic colistin resistance.

Salmonella is the genus name for a group of bacteria that consists of two species; Salmonella bongori and Salmonella enteric. Salmonella enterica is responsible for the majority of Salmonella infections in warm-blooded animals, according to the article "Characterization of Salmonella enterica Subspecies I Genovars by Use of Microarrays" published in the Journal of Bacteriology.

Jan 24, 2019  · Abstract. Macrophages are critical mediators of the inflammatory process, playing a relevant role in the pathogenesis of Salmonella Typhimurium. The protocols for isolation, culture, and differentiation of monocytes into macrophages and their interaction with Salmonella are well established in humans and murine models, but little information is available in swine.
