Current Technologies for Pseudomonas spp. And Ralstonia solanacearum Detection and Molecular Typing

Standard protocols for detection of phytopathogenic Pseudomonas spp. and Ralstonia solanacearum in plant material, soil, water or other sources, often still rely on the isolation of bacterial colonies on appropriate media, and/or on the use of serological techniques. However, over the last several years, molecular techniques, mainly based on PCR methods after extraction of nucleic acids from samples, have improved enough to allow a more rapid, reliable detection of these bacteria. When maximum accuracy is required the use of multiple techniques in an integrated approach is advised. Other promising technologies like flow cytometry, electronic nose or microarrays are emerging due to the need …
