Bremia lactucae is a plant pathogen. This microorganism causes a disease of lettuce (Lactuca sativa) denominated as downy mildew. Some other strains can be found on 36 genera of Asteraceae including Senecio and Sonchus. Experiments using sporangia from hosts do not infect lettuce and it is concluded that the fungus exists as a quantity of host-specific strains (formae speciales). Wild species, such as Lactuca serriola, or varieties of Lactuca can hold strains that infect lettuce, but these pathogens are not sufficiently common to seriously infect the plant.
Feline probiotic Lactobacilli
According to the invention there is provided a strain of lactic acid bacteria of the genus Lactobacilli obtainable by isolation from resected and washed feline gastrointestinal tract having a probiotic activity in animals. Methods of use and compositions comprising the Lactobacilli of the present invention are also provided.
