Small colony variants (SCVs) of Staphylococcus aureus--a bacterial survival strategy. Small colony variants (SCVs) of Staphylococcus aureus have been implicated in chronic recurrent infections and have therefore gained renewed interest durin...

Bacterial stain and culture. In order to prepare a required active synchronised bacterial suspension for our study, we followed the standard procedure: bacterial colonies of E. coli MG1655 were stored at 4 °C. A single colony was inoculated into a test tube containing 5 mL of liquid...
The number of bacterial cells in soil that form colonies on nutrient agar represent a small fraction of the direct microscopic counts (DMC). The colony-forming cells have larger cell dimensions than the very small ("dwarf") cells which represent the majority of the DMC. This may indicate that...
Flight cages or aviaries give birds more space to fly from perch to perch. They are usually designed to house a group of birds. Anideal aviaryfor a colony should be 4 feet (48 inches) wide, 12 feet (144 inches) long, and 8 feet ( 96 inches) high. ...
we also describe a mechano-response of bacterial cells that tunes the emerging distribution of cell sizes (or lengths)23during the evolution of the growing colony. This mechano-response represents a cell’s ability to sense local surroundings, stimuli as well as the presence of other cells24,25...
instruments include incubators, gram stainers, bacterial colony counters, autoclave sterilizers, and petri dish fillers. This lab equipment is widely used in several industries, such as drug development, microbiology labs, biotechnology, and research institutes, to conduct experiments and analyze samples...

Spatially explicit, genome-scale metabolic modeling recapitulated observed colony size variation. Competitors that determine territory size, according to Voronoi diagrams, were the most important drivers of variation in colony size. However, the relative importance of different competitors changed through ...
Discussion By the use of a microfluidic device we have performed experiments of bacterial colony growth under controlled flow conditions, observing traveling waves and measuring their propagation speed. In addition to a direct meas- ure of the propagation speed at zero flow in liquid medium, we ...
