Overview

Randomized trial detects Pasteurella multocida and resistance genes in lung tissues, suggesting implications for treatment.

Key Points

  • This research aims to detect Pasteurella multocida in calf pneumonia and identify associated macrolide resistance genes.
  • Analyzed 100 lung tissue samples from necropsied calves using immunohistochemical methods.
  • Performed real-time PCR to investigate macrolide resistance genes in P. multocida positive cases.
  • P. multocida was detected in 55% of cases, with 82% prevalence in fibrinous bronchopneumonia cases.
  • Macrolide resistance genes were found in 71% of positive cases, with the msr(E) + mph(E) combination occurring in 22%.
