Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry

(< 0.9 μgkg−1). The quantification per-formed by isotopic dilution allowed the complete correction of matrix effect and led to very good validation data with a meanrecovery close to 100% and ...

Experimental bluetongue virus superinfection in calves previously immunized with bluetongue virus serotype 8.

unexpectedly contaminated by BTV serotype 15 (BTV15). BTV1 and BTV15 single infections were performed on two other groups of three BTV naïve calves. A severe clinical picture was obtained after superinfection ...

Neospora caninum is associated with abortion in Algerian cattle2844

Seroprevalences were 16.0%, 34.3%, and 18.6% in groups 1, 2, and 3, respectively. A case control study was performed to investigate the link between global seropositivity to N. caninum and abortion risk in those ...

Shigellosis outbreak linked to canteen-food consumption in a public institution: a matched case-control study36545

was conducted to assess the extent, discover the source and to implement further measures. We performed a matched case-control study to test an association between shigellosis and canteen-food ...

Cross-reactivity of some commercially available deoxynivalenol (DON) and zearalenone (ZEN) immunoaffinity columns to DON- and ZEN-conjugated forms and metabolites.

a semi-quantitative multi-mycotoxin ultra-performance liquid chromatography-tandem mass spectrometry method. The DON IAC s showed cross-reactivity for nearly all DON derivatives tested. The ZEN IAC s showed limited ...

Methodologies for Salmonella enterica subsp. enterica subtyping: gold standards and alternatives.

routinely performed by serotyping, a method in which surface antigens are identified based on agglutination reactions with specific antibodies. The serotyping scheme, which is continuously updated as new ...
