Salmonella Infection Level in Danish Indoor and Outdoor Pig Production Systems measured by Antbodies in Meat Juice and Faecal Shedding on-farm and at Slaughter [PDF]

, 2007
The prevalence of Salmonella shedding was compared in 34 organic, conventional outdoor, and indoor pig herds. Individual faecal and meat juice samples from 30-50 pigs per herd were analysed for presence of Salmonella, and Salmonella antibodies ...

Bayesian estimation of diagnostic accuracy of fecal culture and PCR-based tests for the detection of Salmonella enterica in California cull dairy cattle. [PDF]

, 2020
Epidemiological studies of low prevalence disease problems are often hindered by the high cost of diagnostic testing. The objective of this study was to evaluate PCR screening of both individual and pooled fecal samples from culled dairy cows for the ...

Infection-generated electric field in gut epithelium drives bidirectional migration of macrophages. [PDF]

, 2019
Many bacterial pathogens hijack macrophages to egress from the port of entry to the lymphatic drainage and/or bloodstream, causing dissemination of life-threatening infections. However, the underlying mechanisms are not well understood.

Porin‐Independent Uptake of Small Molecule Antibiotics Facilitated by Escherichia coli Outer Membrane Vesicles

Biotechnology and Bioengineering, EarlyView.
We demonstrate that bacterial outer membrane vesicles (OMVs) can enhance antibiotic delivery into Gram‐negative bacteria by bypassing porin‐dependent uptake. Encapsulation of imipenem in OMVs significantly increased its effectiveness against multidrug‐resistant clinical isolates, highlighting OMVs as a promising platform for overcoming permeability ...

Antimicrobial prescribing practices for enteric bacterial infections in an integrated health care system, Wisconsin, 2004–2017

Journal of Infection and Public Health
Background: Few studies have evaluated antibiotic prescribing practices for bacterial enteric infections. Unnecessary antibiotics can result in adverse events and contribute to the emergence of antimicrobial resistance.

Pathogenesis of Salmonella-induced enteritis

Brazilian Journal of Medical and Biological Research, 2003
Infections with Salmonella serotypes are a major cause of food-borne diseases worldwide. Animal models other than the mouse have been employed for the study of nontyphoidal Salmonella infections because the murine model is not suitable for the study of ...

The putative AraC-type transcriptional regulator STM1082 facilitates Salmonella pathogenicity through modulation of intestinal invasion and intracellular replication

Virulence
Salmonella is a food-borne zoonotic pathogen that causes human gastroenteritis and potentially fatal systemic infections. The invasion of intestinal epithelial cells and the survival and replication within host macrophages are essential for the ...
