Occurrence of virulence factors in Cronobacter sakazakii and Cronobacter malonaticus originated from clinical samples.

Background: Cronobacter spp. are Gram-negative, facultative-anaerobic, non-spore forming, enteric coliform bacteria, which belongs to the Enterobacteriaceae family. Cronobacter spp.

Antibiotic Susceptibility of spp. Isolated from Clinical Samples.

spp. have been recognized as causative agents of various severe infections in pre-term or full-term infants as well as elderly adults suffering from serious underlying disease or malignancy. A surveillance study was designed to identify antibiotic resistance among clinical spp.

Multilocus Sequence Typing of Cronobacter Strains Isolated from Retail Foods and Environmental Samples.

Cronobacter spp. are bacterial pathogens that affect children and immunocompromised adults. In this study, we used multilocus sequence typing (MLST) to determine sequence types (STs) in 11 Cronobacter spp.

Differentiation of Cronobacter spp. by tryptic digestion of the cell suspension followed by MALDI-TOF MS analysis.

Intact cell MALDI-TOF mass spectrometry is a rapid tool for the identification and classification of microorganisms, now widely used even in clinical laboratories. However, its distinctive power is not sufficient for some closely-related species. The genus Cronobacter, formerly known as Enterobacter sakazakii, contains such species.

Deoxynivalenol and its conjugates in beer: a critical assessment of data obtained by enzyme-linked immunosorbent assay and liquid chromatography coupled to tandem mass spectrometry.

Enzyme-linked immunosorbent assays (ELISAs) are often employed for the control of deoxynivalenol (DON) in barley and other intermediates involved in beer production chain. Because of the occurrence of high levels of DON-3-glucoside (DON-3-Glc) in malt and beer that have been reported for the first time in our earlier study, research focused on the accuracy of DON determination by immunoassays in cereal-based matrices has been initiated. DON-3-Glc was strongly cross-reacting in all examined commercial ELISA test kits (Ridascreen) DON (R-Biopharm), Veratox 5/5 DON) (Neogen Corporation), Deoxynivalenol EIA (Euro-Diagnostica), and AgraQuant) DON Assay 0.
