Coliform bacteria are commonly found in the intestine of humans and warm blooded animals. A specific subgroup of coliform bacteria is feacal coliform bacteria, with the most common member in the subgroup being Escherichia coli (E.coli).

 

The presence of faecal coliform bacteria, though being relatively less health hazardous to human, indicates that samples may be feacal contaminated. As faecal coliform bacteria is abundance in faeces and is relatively easy to detect, it is usually used as an indicator organism of contamination. Positive results of feacal coliform or E.coli in the samples also indicate the existence of other pathogenic organisms, thus reflecting the potential health risks for individuals being exposed to samples being tested.

 

Enviro Labs Ltd. (ELL) has been granted HOKLAS accreditation for coliform, faecal coliform and E.coli tests. Different detection methods are employed to suit your needs. Below is a summary of coliform and E.coli tests offered by Enviro Labs.

大腸桿菌群 (coliform) 常見於人類和溫血動物的腸道。大腸桿菌群的一個特定亞群是糞便大腸桿菌群 (faecal coliform) ，該亞群中最常見的成員是埃希氏大腸桿菌 (E.coli)。

​

糞便大腸菌群的存在雖然對人類健康危害相對較小，但陽性結果表示樣本已可能受到糞便污染。由於糞便中大腸菌群含量豐富且相對容易檢測，因此通常被用作污染的指示菌。樣本中糞便大腸桿菌群或埃希氏大腸桿菌的陽性結果也顯示其他病原生物的存在，從而反映了暴露於被測樣本的個人潛在健康風險。

 

環境化驗有限公司已獲得 大腸桿菌群 (total coliform)、糞便大腸桿菌群 (faecal coliform) 和 埃希氏大腸桿菌 (E.coli) 測試的 HOKLAS 認可。我們實驗室提供不同檢測方法以滿足您的需求。以下是 環境化驗有限公司提供的大腸桿菌群和大腸桿菌測試摘要。
