Abstract

PURPOSE:To produce a novel antibiotic substance useful as an anticoccidial agent, by cultivating a microorganism, belonging to the genus Actinomadura and capable of producing an antibiotic substance SF-2361 and collecting the antibiotic substance SF-2361 from the resultant culture. CONSTITUTION:Actinomadura sp. SF-2361 strain is sultivated in a culture medium, containing well-known nutrient sources utilized for cultivation of the conventional actinomycetes. The cultivation temperature at that time is preferably 26-32 deg.C, and the production of the substance SF-2361 reaches the maximum of accumulation normally for 2-10 days. An organic solvent immiscible freely with water, e.g. ethyl acetate, is added to the culture containing active components to extract the components, and the solvent of the extract containing the active components is distilled away to give an oily material. A solvent, e.g. petroleum ether, is added thereto to precipitate the active components. The resultant precipitates are dissolved in a small amount of a solvent to isolate the substance SF-2361 by chromatography of combined silica gel, etc.

Test Example A group of 5 male white Leghorn chicks, 8 days old, were used.
Five groups were established. Groups 1 to 3 were fed feed to which the sodium salt of SF-2361 was uniformly added at a rate of 5 ppm, 10 ppm, and 15 ppm, respectively. The first group was born on the day after the start of feeding, and the fourth group received Eimeria.
Mature oocysts of Eia+eria tenella were orally infected at s, oxio' per bird. In addition, feeding and water were allowed ad libitum during the test period. Eight days after infection, chicks from all groups 1 to 5 were weighed and dissected to determine the strength of the cecal lesions.

Furthermore, the oocyst value in 1 g of cecal stool was measured, and the oocyst value was determined according to Table 6. In addition, the rate of increase in body weight was determined for each group, and the relative rate of increase in body weight for each group was calculated by setting the rate of increase in body weight of the non-infected control group as 100.
