Legionella infections are common globally. The bacterium is known to cause frequent airborne and lung infections. The bacterium Legionella pneumophila is found in both non-potable and potable water systems. In the United States, annually, an estimated 12,000 to 18,000 people are infected with the Legionella bacteria. The main source of infection is water distribution systems of huge buildings which includes, ponds, which includes hospitals and hotels. Cooling towers have long been thought to be a leading source of Legionella, but current data suggests that this might be an exaggerated mode of transmission. Other probable sources include humidifiers, whirlpool spas, hot springs, mist machines etc. Research findings suggests that air conditioners are not source of Legionnaires disease. Increasing health safety issues and maintaining water resources are key factors that are anticipated to drive the expansion of the market.
The report on global Legionella Testing Market has been classified on the basis of four categories: test type, applications, end-user, and geography. Global legionella testing market by test type has been segmented as Culture Methods, Urinary Antigen Test (UAT), seaherology, Direct fluorescent antibody test (DFA), Nucleic acid-based detection. In terms of test type the UAT is anticipated to hold large share of the market. Detection of soluble Legionella antigen in urine specimen is a quick method that offers an early diagnosis of Legionella infection. UAT has been a valuable tool for the investigation of outbreaks of Legionnaires’ disease for the last few years.
Commercial kits that employ both radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (EIA) methodologies have been available for several years and have similar performance characteristics. This test is easy to perform and can provide a result within 15 min. Additionally the key factors responsible for the expansion of this segment are the test has specificity (100%) and sensitivity (70-90%), which can be enhanced after a prolonged incubation time until 60 minutes. After UAT, Nucleic acid detection & serology are anticipated to hold major share of the market. Well-planned studies are required in order to accomplish the best standard test which facilitates optimization of Legionella infection diagnostic market in the near future.
By application the market has been segmented as clinical testing methods, environmental testing methods. Clinical testing methods are expected to hold major share of the market due to rise in incidences of legionella infections. Legionella spp. are omnipresent and can be isolated from 30% to 55% of freshwater bodies, including man-made water systems. In man-made water systems such as cooling tower and storage tanks, legionella can rapidly grow and spread to susceptible hosts. By end users the market has been segmented as hospitals, diagnostic laboratories, clinics, others. Diagnostic laboratories segment is anticipated to hold major share of the market.
Diagnostic laboratories offer a range of diagnosis solutions. Multiplexed diagnostic methods have revolutionized the process of medical diagnosis by enabling early and precise identification of pathogens and accurate therapeutic treatments. Several molecular diagnostic assays have been developed recently using various multiplexed diagnostics technologies. Expansion of outpatient settings in diagnostic centers offering rapid diagnosis is also favoring the Legionella testing market, due to faster results and lesser cost.
Key players operating in the global legionella testing market are IDEXX Laboratories, Inc., Becton, Dickinson and Company, Thermo Fisher Scientific, Inc., Bio-Rad Laboratories, Inc., BioMérieux Inc., and Qiagen N.V. among others.
