A New High-throughput Screening (HiTS) Method for Phages - Enabling Crude Isolation and Fast Identification of Diverse Phages with Therapeutic Potential

Bacteriophage therapy and application of phages as biocontrol in plant production and food processing, all necessitates acquisition of suitable phages. Depending on purpose, the selection criteria of phage characteristics include lifestyle (lytic/lysogenic), host range, physical stability and absence of unwanted genetic traits such as integrases, antibiotic resistance or bacterial virulence factors. The exclusivity of antibiotic resistant clinical infections and possible development of phage-resistance instigates a need to continually build sizeable phage libraries and also be able to rapidly isolate and characterise novel phages of specified bacterial hosts. Current methods for phage isolation are both laborious and time consuming, suitable only for the isolation of a limited number of phages. Thus, we developed the High-Throughput Screening (HITS) method for phages for fast isolation and identification of potentially hundreds of distinct phages against single hosts. This scalable method enables screening of hundreds of samples, in multiple simultaneous setups with varying parameters increasing the likelihood of isolating multiple distinct phages specific for the given conditions. The efficiency of the method is emphasised by ...Continue Reading

Actin, Myosin & Cell Movement

Contractile forces generated by the actin-myosin cytoskeleton are critical for morphogenesis, but the cellular and molecular mechanisms of contraction have been elusive for many cell shape changes and movements. Here is the latest research on the roles of actin and myosin in cell movement.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
