摘要

Viral attachment to nonhost surfaces can influence host-viral infection rates; however, the prevalence and significance of viral attachment to nonhost surfaces remain largely unknown. Yamada et al. (e01687-19) used coastal seawater viral assemblages and isolates and revealed the extent to which viruses attached to various nonhost surfaces, such as bacteria, polymers, filters, cover glasses, and tube surfaces. This study cautions against commonly used protocols that require viral incubation and seawater fractionation and suggests that viral attachment to nonhost surfaces could influence biogeochemical cycles and microbial community structure in the ocean.Magnetosomes, which are intracellular bacterial organelles for magnetic navigation, are aligned along the motility axis of the cell by a unique complex cytoskeletal network. However, the significance of the individual cytoskeletal constituents for effective magnetotaxis in the geomagnetic field had not been quantified. Pfeiffer and Schler (e01976-19) investigated the magnetic alignment of Magnetospirillum gryphiswaldense strains deficient in various cytoskeletal proteins by live-cell motility tracking and a soft-agar swimming assay. The findings suggest that the magnetic properties and intracellular positioning of magnetosomes by the dedicated magnetoskeleton are required and optimized for the most efficient locomotion within the weak geomagnetic field.
