A magnetar giant flare in the nearby starburst galaxy M82.

Magnetar giant flares are rare explosive events releasing up to 10 erg in gamma rays in less than 1 second from young neutron stars with magnetic fields up to 10 G (refs. ). Only three such flares have been seen from magnetars in our Galaxy and in the Large Magellanic Cloud in roughly 50 years.

Uncommon Salmonella Infantis Variants with Incomplete Antigenic Formula in the Poultry Food Chain, Italy.

Uncommon Salmonella Infantis variants displaying only flagellar antigens phenotypically showed identical incomplete antigenic formula but differed by molecular serotyping. Although most formed rough colonies, all shared antimicrobial resistances and the presence of usg gene with wild-type Salmonella Infantis. Moreover, they were undistinguishable wild-type Salmonella Infantis by whole-genome sequencing.

Monophasic Variant of Typhimurium 4,[5],12:i:- (ACSSuGmTmpSxt Type) Outbreak in Central Italy Linked to the Consumption of a Roasted Pork Product (Porchetta).

The monophasic variant of . Typhimurium 4,[5],12:i:- (MVST) is the third most commonly reported serovar involved in human infections (8.8%) in the EU and ranks after .

A multi-center validation study on the discrimination of sg.1, sg. 2-15 and non- isolates from water by FT-IR spectroscopy.

This study developed and validated a method, based on the coupling of Fourier-transform infrared spectroscopy (FT-IR) and machine learning, for the automated serotyping of serogroup 1, serogroups 2-15 as well as their successful discrimination from non-. As presents significant intra- and inter-species heterogeneities, careful data validation strategies were applied to minimize late-stage performance variations of the method across a large microbial population. A total of 244 isolates were analyzed.

Whole-Genome Sequence of Salmonella enterica Serovar Bispebjerg from Turkey Reveals Its Pathogenic Potential.

We report the genome sequence of a Salmonella enterica subsp. serovar Bispebjerg strain that was isolated from a turkey flock in 2011. The genome analysis of the strain, a rare and multihost serovar, revealed its pathogenic potential due to antimicrobial resistance and a plethora of Salmonella pathogenicity islands and virulence factors.
