It closely resembles the typhoid bacillus, but is distinguished from it by its behaviour in artificial culture media. It has been found possible by varying in many ways the character of the culture medium and temperature to grow under artificial conditions outside of the body most, if not all, of the bacteria which cause disease. This large and very irregular surface is bathed in fluid which is a good culture medium and but a single layer of cells covers it. Examples of culture mediumculture medium An improved culturemedium supports development of random-bred 1-cell mouse embryos in vitro. Culturemedium was changed every day and the growth and development of embryos and colonies were examined daily. Immediately after the detection of a single trypanosome in the drop, 0-1 ml of fresh culturemedium was rapidly added to the well. The wells were overlaid with a mixture of agarose and tissue culturemedium and incubated for 7-13 days. Cleaved embryos were transferred to fresh culturemedium supplemented with glucose (5 mg/ml) and incubated for another 2 days to the morula/blastocyst stage. Fertilized eggs are transferred into a special culturemedium for further growth. Immediately after a daily motility score was recorded, each worm was transferred daily to a new well containing fresh culturemedium containing extracts. The rate of uptake of glucose and pyruvate can be related to their respective concentrations in the culturemedium. A few specimens were lost during transfer between different culture media or between culturemedium and microscopic slides. These differences in phosphorylation might be due to different maturation conditions, especially the different culturemedium additives. Pellets were prepared with the fungus mycelia in liquid culturemedium and contained approximately 20% fungus. Tachyzoites (4i10%) were incubated for 30 min in cell culturemedium with decreasing concentrations of serum. Nuclear-cytoplasmic 'tug of war' during cloning: effects of somatic cell nuclei on culturemedium preferences of preimplantation cloned mouse embryos. Before culture, the oocytes were washed three times in a maturation culturemedium. Prior to inoculation, larvae were suspended in physiological saline after repeated washings with culturemedium.
