Harvesting and Disaggregation: An Overlooked Step in Biofilm Methods Research.

Biofilm methods consist of four distinct steps: growing the biofilm in a relevant model, treating the mature biofilm, harvesting the biofilm from the surface and disaggregating the clumps, and analyzing the sample. Of the four steps, harvesting and disaggregation are the least studied but nonetheless critical when considering the potential for test bias. This article demonstrates commonly used harvesting and disaggregation techniques for biofilm grown on three different surfaces.

Complete Genome Sequence of Brucella abortus Phage EF4, Determined Using Long-Read Sequencing.

Brucellaphage EF4 was isolated from elk feces. The 38,321-bp double-stranded DNA genome is predicted to contain 72 coding regions, 38 of which have been assigned predicted functions. This phage displays nucleotide similarity to other brucellaphages of the genus .
