A highly novel Streptomyces phage, Satis, was isolated from a direct environmental sample collected from outside Danforth House on the Washington University campus. Satis infects bacterial species Streptomyces lividans producing pinpoint, cloudy plaques less than 1mm in diameter. Electron microscope data shows rare atypical physical features. Rather than the common octahedral capsid shape, Satis has a prolate head with visible cross-linked hexagonal protein structure and average measurements of 285 nm by 47 nm with a long, flexible tail measuring 268 nm. Upon sequencing, it was found that Satis contains the longest phage genome discovered to date through the SEA-PHAGE program …

Ciliary function is known to play an important role in many human conditions, including chronic sinus and pulmonary diseases and problems with infertility. Cilia are cytoskeletal structures that protrude from the cell body to facilitate movement. Ciliary structure is conserved throughout eukaryotes, from unicellular to multicellular organisms, including humans. A clear understanding the proteins that compose cilia and how they interact with one another will increase our knowledge about important cytoskeletal elements. Because cilia are difficult to study in multicellular organisms, the unicellular eukaryote Tetrahymena thermophila serves as a useful model for the study of cytoskeletal genes, due to their …

Actinomycetes are gram positive, filamentous bacteria that produce useful antibiotics, antitumor agents, and agricultural products. A series of enrichments were undertaken to isolate actinomycetes from local soils, varying enrichment media, antibacterials, and soil treatments (including heat and CaCO3). Isolates were characterized by 16S rDNA sequencing, phenotypic and morphological observations, and antibiotic production. The genetic tractability of select isolates was analyzed using a panel of integrating vectors derived from ɸC31, ɸBT1, and OzzyJ phage using intergeneric conjugation. Further, a semi-degenerate multiplex PCR assay to detect ɸBT1 genomic integrants was designed and tested for the first time. Finally, PCR screens were used …
