Popis: | Mycoplasma pneumoniae frequently causes community-acquired pneumonia in children; β-lactam antibiotics are ineffective against this bacterium because of its lack of a cell wall. Hence, a rapid and simple detection method is required to ensure appropriate treatment. In this study, we developed a rapid and simple immunochromatography-based detection method using monoclonal antibodies that react with the co-chaperone GroES of M. pneumoniae . Mice were immunized with recombinant GroES, and hybridoma cells producing anti-GroES monoclonal antibodies were established. For the development of the immunochromatographic test, antibody pairs with superior reactivity and specificity were selected. The developed immunochromatographic test could detect 0.1 ng/mL of recombinant GroES within 20 min. Moreover, no cross-reaction was observed with other microorganisms, including six Mycoplasma species, 20 other bacterial species, and one yeast species. Macrolide-resistant and -susceptible M. pneumoniae clinical isolates were detected at approximately 104 to 105 colony-forming units/mL. The study indicates that immunochromatographic tests targeting GroES are useful for rapid and simple detection of M. pneumoniae. |
