------- Ralstonia solanacearum (phylotype IIB-3) has been recovered from Heliconia species from virgin forest in the Coto valley, southwest Costa Rica, suggesting that Moko was originally endemic in the rainforests of the Caribbean area. Moko disease has been present in Costa Rica since the start of the 20th century, with reports of small fluidal round (SFR) colony-forming strains being insect transmitted since 1960.

------- Interceptions in the USA of R. solanacearum phylotype IIB-4 on Anthurium and Epipremnum aureum originating from Costa Rica. These strains differed from phylotype II strains already present in the USA and were pathogenic on a wider range of hosts including tomato, tobacco, and potato but also anthurium and pothos and caused mild symptoms on banana. Wicker et al. (2007) suggested these strains to be pathogenic variant R. solanacearum [phylotype IIB-4NPB (non-pathogenic to banana)]
