Tildipirosin is a latest generation macrolide that is used to battle infection diseases caused by Gram-negative bacteria. Recent studies have shown the effectiveness of this antimicrobial agent against Actinobacillus pleuropneumoniae; however, little information is available about Glaesserella parasuis, the etiological agent of Glässer's disease. In this study, the Tildipirosin activity to 100 Brazilian clinical isolates of G. parasuis was assessed using a broth microdilution assay. A total of 90% of G. parasuis isolates were sensitive at concentrations ≤ 4 µg/mL Tildipirosin, thus showing to be efficiently controlled by the therapeutic concentration recommended for pigs. On the other hand, a total of ten isolates have shown resistance to this antibiotic, with a minimal inhibitory concentration (MIC) ≥ 8 and ≤ 16 µg/ml. Notably, our findings highly support the use of Tildipirosin for treating Glässer's disease outbreaks, and it also advises the using of MIC approach to monitor the evolution of sensitivity or resistance exhibited by G. parasuis to this molecule, as well as to adjust therapeutic doses when necessary.
