Detection Of Legionella Spp In Clinical And Environmental Samples

Culture is still regarded as the gold standard for diagnosis of Legionella infection, but it is hampered by the slow replication rate and the fastidious growth requirements of legionellae. Legionella urinary antigen detection assays have greatly improved the diagnosis of acute Legionella infection. However, they only detect L. pneumophila serogroup 1 with high sensitivity and specificity.[10]

More recently, nucleic acid amplification techniques, such as the polymerase chain reaction (PCR), have shown promise for the rapid diagnosis of Legionella infection.[11] Nucleic acid amplification techniques enable specific amplification of minute amounts of Legionella DNA, provide results within a short time frame, and have the potential to detect infections caused by any Legionella species and serogroup. New real-time PCR methods, such as the LightCycler® PCR technique, can even speed up the process of detection to a few hours.

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
