head out, test the water(s), force sb's hand, colony-forming unit, reconstituted

35 Iraq Officials Held in Raids on Key Ministry
By CAMPBELL ROBERTSON and TARIQ MAHER
The arrested officials, who included four generals, have been accused of quietly working to reconstitute Saddam Hussein’s Baath Party.




Rick Wagoner, G.M.'s chief executive for the last eight years, will join the heads of the Ford Motor Company, Chrysler and the United Automobile Workers in testifying before Congress on Tuesday and Wednesday.

The hearing comes as the newly reconstituted Congress is still divided on the issue of a separate bailout package for automakers.

(中央社記者何宏儒台北2008年 4月15日電)財團法人中華民國消費者文教基金會抽檢北市公共場所兒童球池遊樂場,發現部分球池內的「球」,其細菌數竟與普通鈔票相當!其中,「路易士室 內兒童樂園」和「信誼基金會-親子館」,球表面「活細菌總數」更達1萬至10萬CFU(colony forming unit;菌落形成單位)/球 而「信誼基金會-親子館」另亦被檢出金黃色葡萄球菌。

Wikipedia article "Colony-forming unit".
In microbiology, colony-forming unit (CFU) is a measure of viable bacterial numbers. Unlike in direct microscopic counts where all cells, dead and living, are counted, CFU measures viable cells. By convenience the results are given as \frac{CFU}{mL}, colony-forming units per milliliter.

Theory

A dilution made with bacteria and peptoned water is placed in an Agar plate (Agar plate count for food samples) or Trypticase soy agar for clinic samples) and expanded in the plate following this pattern.

The theory behind the technique of CFU establish that a single bacteria can grow and become a colony, via binary fission. These colony are clearly different between each other, both microscopical and macroscopical. However, some bacteria do not separate completely during the sample preparation process (Staphylococcus, Streptococcus) and the results of the count will be below the number of individual cells using direct methods.

Uses

This technique allows the user to know how many CFU are per mL in the sample. Therefore, it allows knowing which is the microbiological load and the magnitude of the infection in humans and animals, or the degree of contamination in samples of water, vegetables, soil or fruits and in industrial products and the equipment.

Other applications

Irradiated mice can have their immune systems reconstituted by the injection of bone marrow cells from a non irradiated animal. The injected cells form colonies in the spleen (hence s), each colony representing the progeny of a pluripotent stem cell. Operationally, therefore, the number of colony-forming units is a measure of the number of stem cells.

While Mr. Wagoner said that G.M. had not considered bankruptcy protection as an option, the company’s increasingly dire cash position and plunging sales could force its hand. G.M. had the worst October of any automaker, posting a 45.1 percent drop.

“Clearly you can’t rule out bankruptcy,” said Erich Merkle, an analyst with the accounting and consulting firm Crowe Horwath. “In fact, it’s highly likely if there isn’t some sort of government action.”
