The group of tyrocidines is basic, cyclic peptides, whereas the fraction of gramicidins is neutral, linear peptides. Besides physiological and essential L-amino acids, the components of Tyrothricin also contain D-amino acids. Tyrothricin is produced by the gram-positive aerobic sporeforming bacterium Bacillus brevis (Strain ATCC 8185) during its sporulation phase via the nonribosomal pathway. The efficacy spectrum of Tyrothricin mainly covers gram-positive but also several gram-negative bacteria. Corynebacteria and staphylococci show a broader range of Tyrothricin concentrations for inhibition (2-256 μg\/mL). In contrast to the gramicidin fraction alone, Tyrothricin is able to inhibit all Staphylococcus strains at a maximum concentration of 128 μg\/mL. Among the gram-negative organisms, gonococci and meningococci were the most sensitive germs (96 μg\/mL). Tyrothricin exerts fungicidal effects on a variety of Candida species.Tyrothricin shows an anti-infectious activity against parainfluenza virus (type Sendai).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIn Vivo:\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"padding-left:1em;\"\u003eIn animal models using HSV type 1, a pre-incubation of the virus suspension with Tyrothricin could significantly decrease the lethality in mice. The effect could only be shown after a direct contact between Tyrothricin and the virus. Nevertheless disruption of the integrity of eukaryotic membranes is observed at higher Tyrothricin concentrations in vitro. This effect is exemplified as hemolytic activity of Tyrothricin in in vitro studies and when applied to animals i.v.. In contrast to an intravenous (LD50 mouse: 3,7 mg\/kg) and an intraperitoneal (LD50 mouse: 20-45 mg\/kg) application the oral application is very well tolerated, as Tyrothricin is destroyed in the gastro-intestinal tract.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProducts are for research use only.
