Diagnostic Notes  The bacteria: Moko disease is a bacterial wilt caused by Ralstonia solanacearum invading the vascular tissues of hosts.Ralstonia solanacearum is a species complex with exceptional diversity amongst strains from different hostsand geographical origins. Many strains have less than 70% DNA-DNA homology, which has been considereda threshold level within a species. A general description of this species was provided by Saddler (1994). Adetailed summation of identification techniques for R. solanacearum can be found in the European andMediterranian Plant Protection Organisation Bulletin (2005).Strains of R. solanacearum have been dividedinto five host-specific races and five biovars based on biochemical properties. Both classifications do notconsistently correspond with each other (Hayward 1991, 1994). The term race is misused for R.solanacearum and means pathovar. Race 2 is pathogenic to banana and Heliconia. The race 2 strains clusterinto three multi-locus genotypes: MLGs 24, 25 and 28 (Cook & Sequeira 1994); and are also classified in nineecotypes groups: A, AFV, B, D, H, R, SFR, SFR-C and T (Thwaites et al. 2000, French & Sequeira (1970).Fegan & Prior (2005) proposed a hierarchical classification for R. solanacearum, based on phylogeneticanalysis of 16S-23S ITS and endoglucanase gene sequences, where race 2 strains belong to Phylotype II,sequevars 3, 4 and 6. Prior & Fegan (2005) has developed a multiplex PCR technique for identification of therace 2 strains. Race 2 occurs mainly in tropical areas from South and Central America causing moko and inthe Philippines, causing bugtok disease. According to Fegan (2005), bugtok, which is only know in thePhilippines, and moko are one and the same disease. </ 2.6. ReferencesAlvarez AM (2005) Diversity and doagnosis of Ralstonia solanacearum.
