Essential oil extraction, chemical analysis and anti-candida activity of calamintha nepeta (L.) Savi subsp. glandulosa (Req.) ball-new approaches

A comprehensive study on essential oils (EOs) extracted from different Calamintha nepeta
(L.) Savi subsp. glandulosa (Req.) Ball (CG) samples from Tarquinia (Italy) is reported. In this study,
the 24-hour steam distillation procedure for EO preparation, in terms of different harvesting and
extraction times, was applied. The GC/MS analysis showed that CG essential oils from Tarquinia
(TEOCG) belong to pulegone-rich chemotype. The analysis of 44 samples revealed that along

Detection of mcr-4 positive Salmonella enterica serovar Typhimurium in clinical isolates of human origin, Italy, october to november 2016

In this study we report the detection of the recently described mcr-4 gene in two human isolates of Salmonella enterica serovar Typhimurium. The strains were isolated from faecal samples of two Italian patients with gastroenteritis, collected in 2016. The identified mcr-4 genes (variant mcr-4.2) differed from the mcr-4 gene originally described in a Salmonella strain of swine origin from Italy. Salmonella species could represent a hidden reservoir for mcr genes. © 2018, European Centre for Disease Prevention and Control (ECDC). All rights reserved.
