Planctopirus ephydatiae, a novel Planctomycete isolated from a freshwater sponge.

The microbiome of freshwater sponges is rarely studied, and not a single novel bacterial species has been isolated and subsequently characterized from a freshwater sponge to date. A previous study showed that 14.4% of the microbiome from Ephydatia fluviatilis belong to the phylum Planctomycetes. Therefore, we sampled an Ephydatia sponge from a freshwater lake and employed enrichment techniques targeting bacteria from the phylum Planctomycetes. The obtained strain spb1 was subject to genomic and phenomic cha...

Cadmium-Bacteria Complexation and Subsequent Bacteria-Facilitated Cadmium Transport in Saturated Porous Media.

Cadmium (Cd) contamination is becoming a significant environmental concern due to its persistency in soil. In the subsurface, the fate and transport of Cd are significantly affected by the presence of organic carriers, including bacteria, which are ubiquitous. In this research, facilitated Cd transport by four different bacterial strains in zeolite was investigated by column experiments under three different Cd introduction scenarios (i.e., a Cd and bacteria mixture, Cd and bacteria introduced separately bu...

Molecular Anatomy of the Receptor Binding Module of a Bacteriophage Long Tail Fiber.

Tailed bacteriophages (phages) are one of the most abundant life forms on Earth. They encode highly efficient molecular machines to infect bacteria, but the initial interactions between a phage and a bacterium that then lead to irreversible virus attachment and infection are poorly understood. This information is critically needed to engineer machines with novel host specificities in order to combat antibiotic resistance, a major threat to global health today. The tailed phage T4 encodes a specialized devic...

Preliminary to estimating race rate ratios, contemporary US-specific, health care utilization-based AID prevalence rates and female-to-male...

Impact of race on the association of mineral metabolism with heart failure: the Multi-Ethnic Study of Atherosclerosis.

Alterations in mineral metabolism, such as high phosphorus, high parathyroid hormone (PTH) and high fibroblast growth factor-23 (FGF-23) have been identified as potential risk factors for heart failure (HF). Important differences in the prevalence of mineral metabolism abnormalities and in the risk of HF have been reported across race/ethnic groups. In this study, we evaluated whether the associations of mineral metabolism markers with HF differed by race/ethnicity.

A bacteriophage mimic of the bacterial nucleoid-associated protein Fis.

We report the identification and characterization of a bacteriophage λ-encoded protein, NinH. Sequence homology suggests similarity between NinH and Fis, a bacterial nucleoid-associated protein involved in numerous DNA topology manipulations, including chromosome condensation, transcriptional regulation and phage site-specific recombination. We find that NinH functions as a homodimer and is able to bind and bend double-stranded DNA in vitro. Furthermore, NinH shows a preference for a 15 bp signature sequen...

The geographic mosaic in parallel: matching patterns of newt tetrodotoxin levels and snake resistance in multiple predator-prey pairs.

The Geographic Mosaic Theory of Coevolution (GMTC) predicts that coevolutionary arms races will vary over time and space because of the diverse ecological settings and population histories of interacting species across the landscape. Thus, understanding coevolution may require investigating broad sets of populations sampled across the range of the interaction. In addition, comparing coevolutionary dynamics between similar systems may reveal the importance of specific factors that structure coevolution. Here...

Phage Therapy for treatment of virulent Klebsiella pneumoniae infection in mouse model.

Klebsiella pneumoniae is an important emerging pathogen of humans and animals which may lead to major clinical implications including mortality. Moreover the increased use of antibiotics has promoted emergence of carbapenem resistant strains and extended spectrum β-lactamase producers (ESBLs) of K. pneumoniae. Recently, phage therapy has gained momentum as a conceivable alternative against emerging antibiotic resistance.
