Legionellosis is mostly caused by Legionella pneumophila and is defined as a severe respiratory illness with a case fatality rate ranging from 5% to 80%. L. pneumophila is ubiquitous in natural and anthropogenic water systems. L. pneumophila is transmitted by inhalation of contaminated aerosols produced by a variety of devices. While L. pneumophila replicates within environmental protozoa, colo...
Microbial exopolysaccharides (EPSs) play key roles in plant-microbe interactions, such as biofilm formation on plant roots and legume nodulation by rhizobia. Here, we focused on the function of an EPS produced by Rhizobium sp. YAS34 in the colonization and biofilm formation on non-legume plant roots (Arabidopsis thaliana and Brassica napus). Using random transposon mutagenesis, we isolated an E...
The bacteria that colonize humans and our built environments have the potential to influence our health. Microbial communities associated with seven families and their homes over 6 weeks were assessed, including three families that moved their home. Microbial communities differed substantially among homes, and the home microbiome was largely sourced from humans. The microbiota in each home were...
The ability of arbuscular mycorrhizal fungi (AMF) to influence the performance of nonnative invasive plants in their introduced range has received increasing attention. The dependence of the invasive nonnative vine pale swallow-wort on AMF was studied in three greenhouse experiments. The aims of the present work were to (1) determine AMF colonization levels of field-collected pale swallow-wort ...
Traditional microbiology concepts are being renewed since the development of new microbiological technologies, such as, sequencing and large-scale genome analysis. Since the entry into the new millennium, a lot of new information has emerged regarding the oral microbiome. This revision presents an overview of this renewed knowledge on oral microbial community acquisition in the newborn and on t...
Chronic inflammation associated with cigarette smoke fosters malignant transformation and tumor cell proliferation and promotes certain nonneoplastic pulmonary diseases. The question arises as to whether chronic inflammation and/or colonization of the airway can be attributed, at least in part, to tobacco-associated microbes (bacteria, fungi, and spores) and/or microbial toxins (endotoxins and ...
Considerable research has been conducted and published regarding the efficacy of ARROWg + ard, chlorhexidine and silver sulfadiazine in suppressing microbial colonization, and their effect on reducing hospital costs. A catheterrelated bloodstream infection can prolong hospitalization and substantially add to the cost of hospitalization. In addition, numerous studies have investigated the incide...
Microbial colonization and alteration of basaltic glass J. Einen, C. Kruber, L. Øvreås, I. H. Thorseth, and T. Torsvik Department of Biology, University of Bergen, Jahnebakken 5, N-5020 Bergen, Norway Department of Earth Science, University of Bergen, Allegt. 41, N-5007 Bergen, Norway Received: 20 December 2005 – Accepted: 5 January 2006 – Published: 7 March 2006 Correspondence to: J. Einen (jo...
Oral infections have a strong ethnic predilection; suggesting that ethnicity is a critical determinant of oral microbial colonization. Dental plaque and saliva samples from 192 subjects belonging to four major ethnicities in the United States were analyzed using terminal restriction fragment length polymorphism (t-RFLP) and 16S pyrosequencing. Ethnicity-specific clustering of microbial communit...
Considerable research has been conducted and published regarding the efficacy of ARROWgard Blue, chlorhexidine and silver sulfadiazine in suppressing microbial colonization, and their effect on reducing hospital costs. A catheter-related bloodstream infection can prolong hospitalization and substantually add to the cost of hospitalization. In addition, numerous studies have investigated the inc...
