Bacterial Cellulose Hybrid Composites with Calcium Phosphate for Bone Tissue Regeneration.

Bacterial cellulose (BC) is a unique microbial biopolymer with a huge number of significant applications in the biomedical field, including bone tissue engineering. The present study proposes to obtain and characterize BC hybrid composites with calcium phosphate as biocompatible and bioactive membranes for bone tissue engineering. BC precursor membranes were obtained in static culture fermentation, and after purification, were oxidized to obtain 2,3-dialdehyde bacterial cellulose (DABC).

Characterization of Staphylococcus aureus strains and evidence for the involvement of non-classical enterotoxin genes in food poisoning outbreaks.

To an increasing extent, molecular and genetic characterization is now used to investigate foodborne outbreaks. The aim of this study was to seek molecular links among coagulase-positive staphylococci (CPS) isolated from three recent food poisoning outbreaks in Romania using polymerase chain reaction and pulsed-field gel electrophoresis techniques. The 19 CPS isolates were identified as Staphylococcus aureus by detection of the 23S rDNA gene.

New insights into the molecular epidemiology of Trichinella infection in domestic pigs, wild boars, and bears in Romania.

Trichinellosis is a food-borne zoonosis caused by the parasitic nematode Trichinella, characterized by an extremely wide host range and geographical distribution. In Romania, it is recognized as one of the most serious zoonotic diseases. A cross-sectional study, covering all regions of Romania, was conducted in 2014 to investigate and update the prevalence of Trichinella infection among domestic pigs, wild boars, and bears.

First study of Salmonella in meat in Romania.

Introduction: The increasing antimicrobial resistance of Salmonella isolates is of major public health concern, but information regarding these aspects is still lacking in Romania. This study focused on a detailed and accurate investigation concerning prevalence, serotypes, and antimicrobial resistance patterns of Salmonella strains, isolated from pork and chicken meat, collected from all regions of Romania in 2011.

Methodology: The research was conducted on 650 samples of chicken and pork meat collected from production units and retail markets located in various regions of Romania.
