Virulence, antimicrobial susceptibility and phylogenetic analysis of Cronobacter sakazakii isolates of food origins from Jordan.

Aims: The aim was to characterize a collection of Cronobacter sakazakii isolates collected from various origins in Jordan.

Methods And Results: The isolates were characterized using 16S rRNA sequencing, DNA microarray, multi-locus sequence typing (MLST), O-serotyping, virulence gene identification and antibiotic susceptibility testing. The identities and phylogenetic relatedness revealed that C.

Leached components from dental composites and their effects on fertility of female mice.

This study investigated the effects of leached components from a resin-based dental composite (Z-100) and bisphenol A (BPA) on female mouse fertility. Leached components or BPA (5, 25 and 100 microg kg(-1)) were administered intragastrically daily to the test and distilled water to the control groups for 28 d. Female mice were then mated with sexually mature untreated males and their fertility was assessed.

Effects of bisphenol A on adult male mouse fertility.

The aim of this investigation was to evaluate the effect of bisphenol A (BPA), a contaminant of resin-based dental composites and sealants, on the fertility of male mice. Forty adult male Swiss mice were divided into four groups of 10. BPA (5, 25 and 100 micro g kg(-1) [corrected] was administered intragastrically daily to the mice in the test groups and distilled water to the control group for 28 d.

Effects of resin based dental composites on fertility of male mice.

The purpose of this study was to investigate the effect of leached substances from dental composites on the fertility of male mice. Twenty adult male Swiss mice were divided into two groups of 10. Leached substances from composite specimens were administered, intragastrically, daily to the mice in the test group and distilled water to the control group for 28 d.
