with the aim to examine lead tolerance of populus nigra (clone 62/154) in symbiosis with arbuscular mycorrhizal fungi, a greenhouse experiment was carried out in a factorial randomized complete scheme with two factors 1) fungal inoculation in 4 levels (control, inoculation with glomus mosseae, inoculation with g. intraradices and inoculation with g. mosseae + g. intraradices) and 2) lead in 4 l...

About 20% of adults are persistently colonized with S. aureus in the anterior nares. Host genetic factors could contribute susceptibility to this phenotype. The objective of this study was to determine whether the phenotype of persistent S. aureus colonization aggregates in family members who live in different households. Healthy adults and their eligible same sex siblings who lived in differen...

Abstract Background and Objective: Bacterial colonization in upper respiratory airways is one of the major risk factors for the development of the ventilator–associated pneumonia (VAP), which is the most common and serious hospital-acquired infection in intensive care unit (ICU). The aim of this study was to determine the frequency of oropharyngeal microorganisms of patients with tracheal t...

Only a minority of cancer cells have the potential to initiate metastatic growth, but the factors that limit metastatic colonization remain mostly unknown. Malanchi et al. (2012) recently demonstrated that stromal periostin is crucial for metastatic colonization by regulating the interactions between breast cancer stem cells and their metastatic niche.

OBJECTIVES To learn about the profile of fungal colonization and related risk factors in premature newborns. METHODS Prospective cohort, from 04/01/2010 to 04/31/2011, with 44 patients admitted to the neonatal intensive care unit, born at the hospital maternity, weighing less than 1,500 g. On admission, data were collected on pre-natal care and childbirth. Clinical and laboratory information,...

Colonization with Candida species is an independent risk factor for invasive candidiasis (IC), but the minimum and most practicable parameters for prediction of IC have not been optimized. We evaluated Candida colonization in a prospective cohort of 6,015 nonneutropenic, critically ill patients. Throat, perineum, and urine were sampled 72 h post-intensive care unit (ICU) admission and twice wee...

Leptospirosis continues to be a disease with a poorly understood pathogenesis. The experimental rat model is amenable for the investigation of leptospiral dissemination, tropism, persistence of renal colonization and factors related to disease resistance. In this study, Wistar rats were infected intraperitoneally with virulent Leptospira interrogans serovar Copenhageni strain Fiocruz L1-130. Th...

REVIEWER COMMENTS. This study was the first to demonstrate that gut bacterial colonization may affect B-cell activation and maturation in humans. The study showed that early colonization of the gut with S aureus, which is increasingly common with improved sanitary conditions in the Western world, is associated with lower counts of circulating memory B cells in infants, whereas early colonizatio...
