The reproductive effort, i.e., percentage of gravid polyps per colony, was higher in large (>50 mm in height) and medium size colonies (30 50 mm) than in small ones (<30 mm).
c Sheep blood chocolate agar inoculated with purulent material along with silicone tube (left eye brow after 11 days of treatment) shows confluent growth of cream colored, opaque, medium size colonies of Staphylococcus aureus and tiny, semi-opaque colonies of Mycobacterium fortuitum (incubation: 4 days, 5%% CO2, 37 °C).
Cell density was intermediate in medium size colonies.
Many differently sized colonies could be observed.
We compared frequencies of fights between pairs of fighters and between fighters and scramblers for large colonies, and for medium-size colonies pooled for all densities (as the frequencies did not differ significantly between densities, Yates χ = 0.079, df = 2, P = 0.961).
On blood agar it formed medium sized whitish non haemolytic colonies and on Macconkey agar it was typical non lactose fermenting colonies (NLF).
Three to five colonies with morphology typical of M. haemolytica (round, medium sized, moist, white-grey colored colonies with some degree of hemolysis evident) were selected for further analysis, streaked onto BAC plates and incubated for 8-12 hrs at 37°C.
These patterns may reflect that species with medium sized foraging ranges are most affected by fragmentation of foraging habitat, because colony size reflects the spatial scale at which bumble bees utilize resources.
Plastic, medium sized bowl.
