Abstract Latent infections of tissue-cultured Anthurium andraeanum Lind. caused by the blight pathogen, Xanthomonas campestris pv. dieffenbachiae (McCulloch & Pirone) Dye, were examined. The pathogen survived in or on callus for over 4 months without producing symptoms in callus or turbidity in the medium. The pathogen survived for more than 1 year on or within stage II shoots without producing symptoms and was successively transferred three times as latently infected shoots were multiplied. The pathogen did not grow or survive for more than 2 weeks in Murashige and Skoog medium lacking plant material. The addition of coconut water enhanced bacterial growth and produced turbidity in culture media. Latently infected in vitro anthuriums may be inoculum sources for subsequent outbreaks of the disease.
