Definicja słowa 콜로니카운트 w słowniku
Jest to rodzaj testu ilościowego dla bakterii zliczających kolonie i służy do oceny bakterii wywołujących. Jest często używany do obliczania liczby bakterii w moczu. W pierwszym etapie najpierw przeprowadza się badanie wymazu moczu, a współczynnik rozcieńczenia moczu określa się, określając liczbę bakterii. Jeśli liczba bakterii jest mała, należy użyć oryginalnego moczu.Jeśli liczba bakterii jest wysoka, rozcieńczyć mocz do 102, 106, wymieszać z agarem, zrobić płaską płytkę i inkubować w temperaturze 37 ° C przez jeden tydzień. Następnie obliczana jest liczba kolonii (kolonii). W ostatnich latach na tym polu postępuje również automatyzacja i możliwe stało się automatyczne oszacowanie. 콜로니카운트 세균검사에서 일종의 정량적 검사법이고 기인균의 추정에 사용된다. 주로 요중의 균수산정에 사용되는 경우가 많은데 객담이나 담즙으로도 실시되는 방법이다. 요에서는 우선 처음에 피검뇨의 도말검색을 하고 균수의 기준을 정해 요의 희석배수를 결정한다. 균수가 적을 때에는원래의 뇨를 사용하고 균수가 많은 경우에는 요를 102, 106에 희석해 한천과 혼합해서 평판으로 한 뒤, 일주일 동안 37°C로 배양한다. 그 뒤 콜로니(집락)수를 산정한다. 최근에는 이 분야에서도 자동화가 진전되어 자동적으로 산정시키는 것도 가능해졌다.

incubated and the colonies observed on these plate count agar plates are then counted as the number of colony forming units (CFUs). The counting of CFUs assumes that every colony is separate and founded by a single viable microbial cell.

Since it is impossible to distinguish colonies arising from individual cells and those from cell clumps, the final population count determined by this method is expressed in colony- forming units per unit volume or weight (i.e., CFU/ml or CFU/g).
