    Area of Science:

    • Microbiology
    • Organic Chemistry
    • Pharmacology

    Background:

    • Streptomyces albus is a known source of diverse bioactive compounds.
    • The emergence of antibiotic resistance necessitates the discovery of new antimicrobial agents.
    • Coccidiosis remains a significant concern in poultry farming, impacting animal health and economic viability.

    Purpose of the Study:

    • To isolate and characterize a novel antibiotic from Streptomyces albus strain No. 6016.
    • To evaluate the antimicrobial spectrum of the isolated compound.
    • To assess the therapeutic efficacy of the antibiotic against coccidiosis in fowl.

    Main Methods:

    • Isolation of the antibiotic using standard microbiological culture techniques.
    • Characterization of the antibiotic's physical and chemical properties, including melting point, molecular formula (C46H77O16Na), and spectroscopic analysis (UV, IR, NMR).
    • In vitro susceptibility testing against Gram-positive bacteria and mycobacteria, and in vivo efficacy studies in avian coccidiosis models.

    Main Results:

    • A new polyether antibiotic, No. 6016, was successfully isolated as colorless prisms.
    • Spectroscopic data indicated the presence of carbonyl and methoxyl functional groups.
    • Antibiotic No. 6016 demonstrated potent activity against Gram-positive bacteria, including mycobacteria.
    • The compound proved effective in treating coccidiosis in fowl.

    Conclusions:

    • Antibiotic No. 6016 represents a promising new polyether compound with broad-spectrum activity against Gram-positive bacteria.
    • Its efficacy in treating avian coccidiosis suggests potential applications in veterinary medicine.
    • Further research into the mechanism of action and safety profile of Antibiotic No. 6016 is warranted.
