Test ID LEGI Legionella Culture

Useful For

Diagnosis of Legionnaires disease

 

Because examination by rapid PCR increases sensitivity and provides faster results, Mayo Medical Laboratories strongly recommends also ordering LEGRP / Legionella species, Molecular Detection, PCR.

Forms: If not ordering electronically, complete, print, and send a Microbiology Test Request Form (T244) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/microbiology_test_request_form.pdf).

Specimen Stability Information

Specimen Type Temperature Time
Varies Refrigerated 48 hours

Clinical Information

The Legionellaceae are ubiquitous in natural fresh water habitats, allowing them to colonize man-made water supplies, which may then serve as the source for human infections.

 

Legionella pneumophila and the related species, Legionella bozemanii, Legionella dumoffii, Legionella gormanii, Legionella micdadei, Legionella longbeachae, and Legionella jordanis have been isolated from patients with pneumonia (Legionnaires disease). The organism has been isolated from lung tissue, bronchoalveolar lavage, pleural fluid, transtracheal aspirates, and sputum. The signs, symptoms, and radiographic findings of Legionnaires disease are generally nonspecific.

Reference Values

No growth

 

Identification of Legionella species.

Cautions

Although a semi-selective media is utilized, recovery of Legionella in specimens heavily contaminated with indigenous flora (ie, sputum) may be difficult.
