Isolates of Phytophthora pathogenic to citrus crops on Eastern Corsica and associated with gummosis were identified by PCR-RFLP of internal transcribed spacers (ITS) sequences and characterized by the random amplified microsatellites (RAMS) technique. A sample of 114 isolates collected from diseased trunks and fruits, and from soil, were overwhelmingly(More)
Yersinia enterocolitica has been isolated from a wide variety of sources throughout the world. The isolation of this organism requires special awareness from bacteriologists. To ease this procedure, we have developed a new isolation medium—BABY 4—meant to be used for environmental studies. Compared with previously recommended media, such as SS agar, SS-D(More)
For the first time systematic measurements of the "ultraweak" photon emission of the human body (biophotons) have been performed by means of a photon detector device set up in darkness. About 200 persons have been investigated. In a particular case one person has been examined daily over several months. It turned out that this biophoton emission reflects,(More)
BACKGROUND/AIMS/METHODS For the first time systematic measurements of the low-level luminescence of the human skin ("bi-ophotons") have been performed by means of a photon detector device set up in darkness. RESULTS Several months of daily investigations have shown that body light emission follows definite and well-known biological rhythms, such as 14(More)
