A novel species of the genus Cryptococcus was isolated from sediment collected on the deep-sea floor of Suruga Bay, Japan. Nucleotide sequences of 18S rDNA, internal transcribed spacers, 5.8S rDNA and the D1/D2 region of 26S rDNA of strain SY-260(T) suggested affinities to a phylogenetic lineage that includes Cryptococcus luteolus. Comparisons of the rDNA sequences of each region clarified that strain SY-260(T) is related distantly to Bullera coprosmaensis and Bullera oryzae, but is distinct at the species level. As ballistoconidia and sexual reproduction were not observed in strain SY-260(T), this strain is described as Cryptococcus surugaensis sp. nov. (type strain, SY-260(T)=JCM 11903(T)=CBS 9426(T)).

Background: Antimicrobial lock therapy is recommended for preventing and treating catheter-related bloodstream infections, but different solutions have uncertain efficacy.
Methods: Two locks, 1.35% taurolidine and 4% ethylenediaminetetraacetic acid (EDTA), were tested on Staphylococcus epidermidis, Staphylococcus aureus, methicillin-resistant S.

Purifying membrane proteins has been the limiting step for studying their structure and function. The challenges of the process include the low expression levels in heterologous systems and the requirement for their biochemical stabilization in solution. The human voltage-gated proton channel (hH1) is a good example of that: the published protocols to express and purify hH1 produce low protein quantities at high costs, which is an issue for systematically characterizing its structure and function.

Catabolic plasmids are critical factors in the degradation of recalcitrant xenobiotics, such as dioxins. Understanding the persistence and evolution of native catabolic plasmids is pivotal for controlling their function in microbial remediation. Here, we track the fitness and evolution of Rhodococcus sp.

Background: Direct acting antivirals (DAAs) have demonstrated remarkable efficacy, in achieving hepatitis C viral (HCV) elimination rates higher than 90%. One particular concern associated with treatment failure is the emergence of resistance associated substitutions (RASs) in the genome. The occurrence of RASs highlights the adaptability and resilience of the HCV.
