A trial was conducted to determine the suitability of using a pelleted diet containing chlortetracycline (CTC) for treatment of chlamydiosis in macaws. Macaws, normally fed seed and fruit diets in captivity, are notoriously difficult to treat with CTC-medicated mash diets. Healthy macaws fed a pelleted diet containing 1% or 1.5% CTC for 30 or 45 days maintained adequate food intake and mean blood concentrations of 1-2 CTC micrograms/ml blood throughout the treatment period. There were no significant differences between blood concentrations induced by the different dietary CTC concentrations. Blood concentrations of 1 microgram/ml are considered therapeutic, so it is likely that 1% CTC-medicated pellets will be adequate for treating chlamydiosis in these species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
