Zusammenfassung: | This invention provides a method for treating chronic respiratory disease, fowl cholera and necrotic enteritis in infected birds, by orally administering thereto a pharmaceutically effective amount of antibiotic LL-E19020 alpha , antibiotic LL-E19020 beta or a physiologically acceptable salt thereof. The physico-chemical characteristics of LL-E19020 alpha are as follows: Approximate elemental analysis : C 62.73; H 7.60; N1.00; 0 28.67 (by difference); Molecular weight: 1225 (FABMS); Apparent molecular formula: C65H95NO21; Specific rotation: [ alpha ]26_D = O (C 0.385, methanol); LL-E19020 beta Approximate elemental analysis: C 63.33; H 7.72; N 1.16; 0 27.79 (by difference); Molecular weight: 1225 (FABMS); Apparent molecular formula: C65H95NO21; Specific rotation: [ alpha ]26_D = -17+/-2(C 0.455, methanol); |
