Tildipirosin inhibited the growth of E. Coli, of which 8 of the 31 isolates (26%) had a MIC >256 μg/mL and 23 of the 31 isolates (74%) had a MIC of 8 or 16 μg/mL. ..For Campylobacter jejuni, the MIC ranges from 8 to 64 μg/mL. Tedikicin has a concentration of 2–8 μg/mL against Escherichia coli and Salmonella enterica[1]. Treponemal isolates from 19 sheep with CODD lesions were suppressed by tildipirosin, with a MIC90 of 0.0469 mg/L [3]. Tediloxin MIC was 0.25 mg/L for the Pasteurella multocida B130 clone. Ten isolates of Pseudomonas multocida that solely have erm(42) had MICs for tedirocin ranging from 16 to 32 mg/L. Just one M. The TEDIloxin MIC of 32 mg/L was observed in haemolyticus bearing just erm(42) [4].

In comparison to calves treated with tulathromycin and control, the mean percentage of lung consolidation in calves treated with tediloxin (4 mg/kg, subcutaneously) was considerably lower. In comparison to the dry prophylactic administration of telamycin Clinical illnesses and lung lesions, the dry prophylactic injection of tediloxin to calves five days prior to a sleep hemophilia challenge prevented subsequent culture of the pathogen from bronchial secretions[2].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 3 mg/mL (4.09 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 30.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 3 mg/mL (4.09 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 30.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
