Quantifying the sources of Salmonella on dressed carcasses of pigs based on serovar distribution.
Summary of "Quantifying the sources of Salmonella on dressed carcasses of pigs based on serovar distribution."
Salmonella serotyping data, qualitatively described by van Hoek et al. (2012), were used to quantify potential sources of Salmonella in a Dutch pig slaughterhouse. Statistical tests to compare per-day Salmonella prevalence and serotyping data from multiple points in the chain were used to find transmission pathways. A statistical model based on serotyping data was developed to attribute Salmonella on dressed carcasses to the most likely source. Approximately two-third of dressed carcasses carrying Salmonella on the medial surface had been contaminated by house flora. For carcasses carrying Salmonella on the distal surface, transient Salmonella from incoming pigs was a more important source. The relevance of the different sources of Salmonella varied within and between sampling days. Results were compared to those of another modeling approach, in which Salmonella concentration data from the same samples were used (Smid et al., 2012). They mostly agreed. The approach chosen by an individual slaughterhouse depends on the data that are collected.

Salmonella enterica subsp. enterica plays a role as a foodborne pathogen worldwide. The consumption of contaminated pork has been associated with human salmonellosis and the increase in antimicrobial ...
Salmonella enterica serovar Typhimurium is the most important serovar associated with human salmonellosis worldwide. Here we aimed to explore the molecular epidemiology and genetic characteristics of ...
Salmonella spp are among the main causative agents of foodborne diseases. Some phenotypes associated with increased drug resistance and virulence are regulated by quorum sensing (QS). In the present s...
BackgroundThe globalization of the food supply and the increased movements of people, animals and goods have increased the threat of Salmonella infections in several countries. The objective of this s...
Salmonella enterica serovar Typhi, the causative agent of typhoid, is endemic in most parts of the world especially in Africa. Reliable and rapid diagnosis of the bacterium is therefore critical for c...
The purpose of this study is to determine whether CVD 1902 (a live, attenuated, oral vaccine) is safe and effective in the prevention of Salmonella enterica serovar paratyphi A infection.
To determine the clinical significance of gene mutations encoding antibiotic resistance, but not expressed as clinical resistance, in Salmonella bacteria
In this Phase I clinical study, three recombinant, avirulent Salmonella Typhi (RASV) strains each expressing the Streptococcus pneumoniae surface protein, PspA, will be compared as live bi...
Background: - The flu is a very infectious and contagious virus that affects both people and pigs. Studies show that pigs can be sources of the flu virus in humans. Researchers want to kn...
