Positive association between the use of macrolides in food-producing animals and pneumococcal macrolide resistance: a global ecological analysis.

The reasons underpinning the large differences in the prevalence of resistance to macrolides in Streptococcus pneumoniae are imperfectly understood. We assessed if the volume of macrolides used in food-animals could play a role. Logistic regression was used to assess if the country-level prevalence of pneumococcal macrolide resistance was associated with country-level macrolide consumption in food animals and humans. In both univariate and multivariate models, macrolide use in food-producing animals was significantly associated with pneumococcal macrolide resistance (coeff. = 339, 95% CI 21 - 658; P = 0.037). In vitro and individual-level studies are required to verify or refute the hypothesis that macrolides used in food animals can promote the spread of macrolide resistance in humans.
