In solid media, catalase activity could not be detected in the agar surrounding colonies of H. capsulatum, suggesting that this enzyme is not constitutively secreted (data not shown).
When a parasitoid female increases its patch residence time in one colony, the probability that surrounding colonies will be found and parasitised by this female decreases.
The militia army continued to grow as surrounding colonies sent men and supplies.
GBS produces a pore-forming exotoxin known as the β-hemolysin/cytolysin (βh/c) that is responsible for the characterstic zone of clearing ("β-hemolysis") surrounding colonies grown on blood agar media.
These surrounding colonies denounced Rhode Island as "Rogues' Island" and tried to extinguish it by purchase, invasion, royal commission, fiat, fraud, and intimidation.
One swells with pride when he thinks of his makeshift newspaper, which he delivers to surrounding colonies; another is a thrice divorced Hollywood-star-turned stage actor who plays Lear in an odd rendition; another, Kirsten, was eight when the pandemic hit, and finds a home in a traveling symphony that performs mostly Shakespeare.
Expression of mRNA coding for IL8 in microdissected tissue surrounding colonies of A. pleuropneumoniae was highly consistent with these findings.
In contrast, field gardens reside in close quarters to the surrounding soil and colonies forage on a wide variety of plant species [9].
Using remotely sensed data and a GIS, we quantified percent urbanization, road density, and the percentage of other prairie dog colonies in the surrounding landscape at 200, 1000, and 2000 m from the perimeter of 22 prairie dog colonies, and compared burrow density with each landscape variable at each scale.
A change in the color of the medium surrounding the colony, from red to yellow, indicated arabinose fermentation.
