BACKGROUND Alaska Native children have high invasive pneumococcal disease (IPD) rates, and lack of in-home running water has been shown to have a significant association with infection. Pneumococcal conjugate vaccines reduced IPD; however, this population saw substantial replacement disease and colonization with nonvaccine serotypes. We evaluated risk factors for nasopharyngeal pneumococcal col...
Background: Over the last two decades invasive candidiasis has become an increasing problem in neonatal intensive care units (NICUs). Colonization of skin and mucous membranes with Candida spp. is important factor in the pathogenesis of neonatal infection and several colonized sites are major risk factors evoking higher frequencies of progression to invasive candidiasis. The aim of this study w...
Eighty-six percent (72 of 84) of heat-labile and heat-stable, none of 141 heat-labile, and 24% (27 of 111) heat-stable enterotoxigenic Escherichia coli isolates from Thailand aggregated in less than 1 M (NH4)2SO4, hemagglutinated human group A and bovine erythrocytes in 1% D-mannose, and possessed either colonization factor I or colonization factor II. No other colonization factors were identif...
Background and purpose: Respiratory failures are common diseases among different populations. Pneumocystis jirovecii colonization causes respiratory failure in children and adults with AIDS and patients with predisposing factors of immunosuppression including malignancies, organ transplant, inherited immune deficiencies and immunosuppressive agents. The aim of this study was to evaluate the eff...
Background & Objectives: One of the important infectious factors in pregnant mothers and newborns is Group B Streptococcus (GBS). There is no perfect report about prevalence of GBS in Iran and in the case of preterm rupture of amniotic membrane or preterm labor all patients are treated by antibiotics without culture so this has led to adverse taking antibiotics and drug resistance. The...
BACKGROUND Staphylococcus aureus infections are increasing among pregnant and postpartum women and neonates, but risk factors for S. aureus colonization in pregnancy and the association between maternal colonization and infant infections are not well defined. We sought to identify risk factors for maternal S. aureus rectovaginal colonization and assess colonization as a risk factor for infectio...
Mycorrhizal fungi are capable of symbiosis with plants. They improve plant growth by increasing absorption of nutrient elements and decreasing salinity and toxicity of some elements. In the present research, the effect of different salinity levels and Mg/Ca ratios on mycorrhiza colonization of Glomus sp. and vegetative traits of Sorghum bicolor was studied in a factorial greenhouse experiment, ...
BACKGROUND An increasing rate of respiratory colonization and infection in cystic fibrosis (CF) is caused by fungi of the Scedosporium apiospermum species complex or Lomentospora prolificans (Sac-Lp). These fungi rank second among the filamentous fungi colonizing the CF airways, after Aspergillus fumigatus. However, the epidemiology, clinical relevance and risk of pulmonary colonization with Sa...
