root colonization by antagonist bacteria has been considered as a prerequisite for a successful biocontrol. for an effective suppression of plant disease, an efficient and fast colonization is necessary to prevent the establishment of pathogen on the root system. colonization of canola root by strain utpf86 were investigated with and without rhizoctonia solani ag-4, under greenhouse conditions....

OBJECTIVE To study the correlation between fungal colonization and bacterial pneumonia and to test the effect of antifungal treatments on the development of bacterial pneumonia in colonized rats. DESIGN Experimental animal investigation. SETTING University research laboratory. SUBJECTS Pathogen-free male Wistar rats weighing 250-275 g. INTERVENTIONS Rats were colonized by intratracheal ...

background: the advantages of coated orthodontic wires such as esthetic and their effectson reduced friction, corrosion and allergic reaction and the signifi cant consequences of plaque accumulation on oral health encouraged us to assess bacterial colonization on these wires. materials and methods: a total of 18 (9 upper and 9 lower) epoxy resin coated 16 × 22 nickeltitanium wires (spectra, gac...

BACKGROUND Bacterial colonization and recurrent infections of the respiratory tract contribute to the progression of chronic obstructive pulmonary disease (COPD). There is evidence that exacerbations of COPD are provoked by new bacterial strains acquired from the environment. Using a murine model of colonization, we examined whether chronic exposure to cigarette smoke (CS) promotes nasopharynge...

Background: Atopic dermatitis (AD) is the most common skin disease in infants and children, influenced by hereditary environmental factors characterized an inflammatory reaction skin. The increase AD has been explained two hypotheses: "hygiene hypothesis" "diet–microbiome hypothesis." driven a familial or personal predisposition to induce immunoglobulin E (IgE) antibodies sensitize response sti...

Background Bronchoscopic valve implantation is an established treatment in selected patients with severe lung emphysema. There is evidence in literature of increased bacterial colonization of various implants. So far, it is unclear if an increased bacterial colonization can also be observed after endoscopic valve therapy. Methods Retrospective analysis of patients with examination of the bron...

Introduction: The purpose of this study was to compare the topical effect of breast milk, chlorhexidine, and dry cord care on the umbilical cord bacterial colonization in premature infants hospitalized in a neonatal intensive care unit. Methodology: This randomized controlled double-blinded trial was performed on premature infants admitted to the NICU of Valiasr Hospital, Birjand in 2016.  The...

BACKGROUND Epistaxis is a common problem in childhood. It has been shown that children with recurrent epistaxis are more likely to have nasal colonization with Staphylococcus aureus. It has been suggested that low-grade inflammation, crusting and increased vascularity due to bacterial colonization contributes to the development of epistaxis in children. AIMS This study aimed to investigate th...
