Effect of Danofloxacin Treatment on the Development of Fluoroquinolone Resistance in in Calves.

is a leading cause of foodborne gastroenteritis. Recent studies have indicated a rise in fluoroquinolone-resistant (FQ-R) in cattle, where FQ is used to control bovine respiratory disease (BRD). To assess the effect of danofloxacin treatment on the development of FQ-resistance in , 30 commercial calves were divided into Group 1, Group 2, and Group 3 ( = 10), and were all inoculated orally with FQ-susceptible (FQ-S) ; seven days later, Group 3 was challenged with transtracheal , and one week later, Group 2 and Group 3 were injected subcutaneously with danofloxacin.

Antibiotic utilization for adult acute respiratory tract infections in United States Emergency Departments.
