Development and validation of detection and control protocols for pathogenic fungi.

Morphological and serological diagnostic protocols for pathogenic fungi are slightly sensitive and they do not allow the detection of the species concerned nor the quantification of the target pathogen. Recently some PCR-based detection techniques have been developed to detect and identify a number of plant pathogenic fungi. These techniques are highly sensitive and reliable, but they are not very effective for quantitative analyses. Most of the disadvantages related  to traditional PCR have been overcome by some adjustments which make it possible to detect the microorganisms through a specific fluorescent signal (real-time PCR).

As a result, the research conducted at MAIB has been directed towards i) delivering real-time PCR-based molecular diagnostic protocols to be used for the quantitative analysis of soil-born and post-harvest pathogens; ii) developing more rapid, simple and reliable detection techniques compared with the traditional ones (1 day for molecular detectin versus 2 weeks or a few months for traditional methods); iii) planning the guidelines for integrated management including also preventive measures.
