This study sought to investigate the prevalence of Giardia in a colony of common marmosets by using a Giardia antigen-capture assay and to address the possible eradication of this infection by using tinidazole, an antiprotozoal similar to metronidazole but requiring fewer doses. Among 31 colony marmosets, 13 (42%) were positive for Giardia. Two doses of oral tinidazole eliminated the infection in all animals. Repeat testing of the 13 Giardia-positive monkeys 1 y later showed that 11 remained negative and that treated animals had a significant increase in weight at 1 y. Giardia antigen is common in common marmoset feces, and treatment using oral tinidazole is possible and highly effective.", pages = "174-179", url = "http://www.ingentaconnect.com/content/aalas/cm/2009/00000059/00000002/art00008" }
