Presentation
The problem is that B. cereus spores are often present in uncooked rice. But because the spores are heat-resistant, they are not always killed when the rice is cooked, particularly if it is steamed or cooked too quickly. [giantmicrobes.com]
Air Sample (culturable) A culturable air sample identifies the types of organisms present in the air that are alive, capable of growing on the agar used, and capable of competing with the other types of fungi present. [emlab.com]
However, they are only present in small numbers and thus difficult to find. 6. Campylobacter jejuni Campylobacter is commonly implicated in outbreaks involving predominantly children. [virology-online.com]
