Wolbachia detection in insects through LAMP: loop mediated isothermal amplification

Abstract Background The bacterium Wolbachia is a promising agent for the biological control of vector-borne diseases as some strains have the ability to block the transmission of key human disease-causing pathogens. Fast, accurate and inexpensive methods of differentiating between infected and uninfected insects will be of critical importance as field-based trials of Wolbachia-based bio-control become increasingly common. Findings We have developed a specific and sensitive method of detecting Wolbachia based on the isothermal DNA amplification. This technique can be performed in an ordinary heat block without the need for gel-based visualisation, and is effective for a wide variety of insect hosts. Conclusion Here we present the development of a rapid, highly sensitive and inexpensive method to detect Wolbachia in a variety of insect hosts, including key mosquito disease vectors.
