An outbreak of Salmonella worthington infection in a neonatal unit occurred in a pediatric ward of Holy Family Hospital, Rawalpindi, Pakistan. The index case was a prematurely born male child from whose clinical specimens S. worthington was recovered. After this finding 40 infants kept in that nursery were included in an investigation. Major symptoms were diarrhea, septicemia and jaundice. Three developed meningitis. Disease morbidity rate was 45% and mortality occurred in 16.6% of the total positive cases. The source of infection was traced to a contaminated rubber tubing of a suction apparatus which was used for oropharyngeal suction of the babies. S. worthington was recovered from the clinical specimens of all 18 babies who received suction. Multiple drug resistance of these S. worthington strains was found.

Article Synopsis
- - The study presents draft genome sequences for two bacterial serovars, Saintpaul ST50 and Worthington ST592, both isolated from raw milk in Northeastern Brazil.
- - The Saintpaul ST50 genome has 4.7 million base pairs and 4,628 genes, while the Worthington ST592 genome is larger at 4.9 million base pairs and contains 4,951 genes.
- - Worthington ST592 features a specific plasmid linked to antimicrobial resistance and a mutation in the ParC gene that could inform future research on the evolution and spread of these organisms.

The genetic diversity of 169 Salmonella isolates from pistachios collected from California storage silos during the 2010, 2011, and 2012 harvests (silo survey isolates) was determined by analyzing the whole genome sequence data using the CFSAN SNP pipeline developed by the U.S. Food and Drug Administration's Center for Food Safety and Applied Nutrition.

Galectin-4, a member of the galectin family of animal glycan-binding proteins (GBPs), is specifically expressed in gastrointestinal epithelial cells and is known to be able to bind microbes. However, its function in host-gut microbe interactions remains unknown. Here, we show that intracellular galectin-4 in intestinal epithelial cells (IECs) coats cytosolic serovar Worthington and induces the formation of bacterial chains and aggregates.
