Pharmacological properties

Spelimix® 44 is a complex drug, which is represents a combination of such antibiotics as lincomycin and spectinomycin with a broad spectrum of synergistic antimicrobial effect.

Lincomycin is an antibiotic of the lincosamides group. It inhibits synthesis of protein in microorganisms, binding ribosomal 50S subunits of bacterial cells. It demonstrates bacteriostatic or bactericidal action depending on concentration. It acts mostly upon gram-positive (Staphylococcus spp., Streptococcus spp., Bacillus anthracis, Corynebacterium spp.) and gram-negative microorganisms (Actinobacillus spp., Bordetella spp., Nocardia spp., Actinomyces spp.) and is particularly effective against Serpulina hyodysenteriae and Mycoplasma spp.

Spectinomycin is an antibiotic of tricyclic structure of the aminoglycosides group. Its efficacy is related to inhibition of synthesis of proteins in microbial cell through binding of ribosomal 30S subunit of microorganisms, which prevents elongation of polypeptide chain at translocation stage. It is mostly effective against gram-negative and gram-positive microorganisms (E. coli, Pasteurella multocida, Salmonella spp., Clostridium spp., Erysipelothrix rhusiopathiae, Haemophilus spp., Vibrio spp.) as well as mycoplasma (Mycoplasma spp.).
