الوصف: Abstract Certain classes of antibiotics, including tetracyclines and macrolides, are known to exert immune suppressive effects in other species but the immune modulatory effects of these antibiotics have not been previously studied in cattle. To address this question, we investigated the effects of oxytetracycline, gamithromycin, and tulathromycin on T cell and macrophage responses to activation, using in vitro assays. In addition, we assessed the impact of these antibiotics on T cell responses in vivo following treatment of healthy cattle with currently recommended doses of each of the three antibiotics. We found that all 3 antibiotics markedly suppressed T cell proliferation in vitro at relevant therapeutic drug concentrations and significantly suppressed macrophage activation responses to LPS. In cattle treated with a single dose of each antibiotic, we observed significant suppression of T cell proliferation and cytokine production beginning as early as 6 h after administration, with increasing immune suppression observed at 48 h. Taken together, these results indicate that commonly used antibiotics in cattle exert significant immune modulatory activity, in addition to their antimicrobial activity. These off-target effects should be considered when using antibiotics for prophylaxis or metaphylaxis in high-risk dairy or beef cattle (192 words).
