Biofilm forming capacity and antibiotic susceptibility of with the icaA/icaD/bap genotype isolated from ocular surface of patients with diabetes.

Introduction: Bacterial biofilm is an exopolysaccharide matrix that is produced by bacteria while they adhere on abiotic or biotic surfaces. The bacteria living in this matrix are more resistant to antibiotics than planctonic bacteria. The biofilm formation property of the bacteria is determined by genes; and this is related to virulence of the microorganism.

Anticandidal activities of lactic acid bacteria isolated from the vagina.

Background/aim: Lactic acid bacteria prevent the overgrowth of pathogenic agents and opportunistic pathogens in the vagina. Moreover, lactic acid bacteria contribute to the preservation of vaginal microbiota by producing antimicrobial agents. Previous studies showed that some lactic acid bacteria exhibited antimicrobial activity against Candida species causing yeast vaginosis as well as many bacterial pathogens.

The newborn conjunctival flora at the post delivery 24 hours.

Purpose: The aim of this study was to investigate the aerobic conjunctival flora of neonates and the effects of delivery type on conjunctival flora development in neonates who were born with normal spontaneous vaginal delivery (SVD) or elective caesarean section (C/S) and who were not given prophylactic antibiotic eye drops after birth.

Methods: This cross-sectional study included 95 healthy newborns. One day after the delivery, conjunctival samples were taken from newborns who were born with normal SVD or elective C/S, and not given prophylactic antibiotic eye drops after birth.

13-93B3 Bioactive Glass: a New Scaffold for Transplantation of Stem Cell-Derived Chondrocytes.

Research using animal models gives human trials hope for recovery in many fields of regenerative medicine, although they are sometimes poor predictors for human experiences. Our goal was to investigate whether rat chondrocytes, differentiated from adipose-derived stem cells, could be transplanted using a new, easily shaped, bioactive glass scaffold, and to show the immunohistochemical results. Intraperitoneal and retroperitoneal adipose tissue was extracted from 6 male Wistar albino type rats.
