Abstract
- Abstract: The present work concerns the innocuity ofHirsutella thompsonii Fisher isolated in Cuba from a citrus rust mite,Phyllocoptruta oleivora Ashm. This phytopathogenic arachnide is an important pest of different citrus fruit plantations. The infectivity tests were performed in 220 animals (mice and guinea pigs) inoculated by intraperitoneal and subcutaneous injections. Animals showed macroscopic alterations such as nodules in the liver capsule, spleen, subcutaneous tissue; superficial fibrinous adhesions on these organs and hepatosplenomegaly. No fungi were recovered from organs at any time and only disintegrated hyphal elements were observed. The histopathological study disclosed a non-specific tissue reaction to a foreign body. The results obtained suggest the non-infectivity and innocuity ofHirsutella thompsonii Fisher in mice and guinea pigs.
