一種新型快速側流分析檢測法，能夠同時檢測所有種類的軍團菌。最常見的優勢菌肺炎軍團菌，可以單獨使用相同的檢測方法進行鑒別。

這種新型檢測方法叫做Duopath Legionella，是由Merck KGaA公司(Darmstadt, Germany)提供的。對從水中或者環境采樣在煤炭酵母菌提取物（BCYE）瓊脂糖培養基或者添加軍團菌選擇性成分的BYCE培養基中擴增的疑似菌落，可是使用這種方法進行驗證。這種檢測方法敏感性極高，降低了假陰性的危險。在一項與廣泛應用的乳膠聚集檢測法進行對比的研究中，Duopath Legionella檢測法對肺炎軍團菌的敏感性為100%，而對Legionella菌株為92%，而乳膠檢測法只有98%和37%。
 
Rapid Lateral-Flow Assay Identifies Legionella
 
A new rapid lateral-flow assay enables the simultaneous identification of all Legionella species. The most prominent species, Legionella pneumophila, can be identified separately using the same assay.

The new test, called Duopath Legionella, is available from Merck KGaA (Darmstadt, Germany). It can be used for confirmation of suspect colonies obtained after enrichment of water or environmental samples on buffered charcoal yeast extract (BCYE) agar medium or BCYE with Legionella-selective supplements. The test is highly sensitive and lowers the risk of false-negative results. In a comparative study with the widely used latex-agglutination assay, the sensitivity of Duopath Legionella was shown to be 100% for Legionella pneumophila and 92% for Legionella species, while the latex assay provided only 98% and 37%, respectively.
