Verbindungen und deren Verwendung zur Behandlung von Protozoeninfektionen

摘要

The present invention relates to the methods and compounds and compositions for the control of protozoal infection, especially coccidial ones, in warm-blooded animals, such as meat-producing animals, i.e., poultry, by administering to the animals a protozoacidally-effective amount of new antibiotics designated LL-D42067 alpha and LL-D42067 beta , NRRL 15734. These novel antibiotics are produced via a controlled conditioned microbiological fermentation using a new strain of Actinomadura madurae subspecies simaoensis or mutants thereof.
