Abstract

Ceftiofur crystalline free acid (CCFA) is a third-generation, oil-based, cephalosporin antimicrobial marketed as a once weekly treatment in cattle and swine, and as a two-Time dose with 10-day duration in horses. Because handling and restraint times can be reduced, long-Acting antibiotic preparations are particularly useful for treatment of nondomestic species. This study evaluated the pharmacokinetics of CCFA in ringneck doves (Streptopelia risoria). A single intramuscular (IM) injection of CCFA at 50 mg/kg was administered to each of 30 doves, and blood was collected from subsamples of 6 birds at predetermined sampling times (i.e., with a postinjection range of 0.5 to 192 hr). All ringneck doves were scheduled for euthanasia because of reasons unrelated to the study; this was performed at the conclusion of the study; and complete postmortem and histopathologic examinations were performed. Plasma concentrations of CCFA remained above the minimum inhibitory concentration (1.0 μg/ml; observed for most avian pathogenic bacteria) for 108 hr. No abnormalities were identified on individual birds before and after clinical pathology results (i.e., hematocrits and plasma biochemistry profiles), and only minimal gross and histopathologic changes such as mild tissue inflammation at the injection site were observed. Based on these results, one IM injection of CCFA at 50 mg/kg seems to be a potential option for treatment of ringneck doves.
