Abstract

Nine poppies two to three months old, developed clinical symptoms of giardiasis three to six days after being purchased from a breeder in Matsuyama-shi, Ehime Prefecture, Japan, in July 1987. Giardian trophozoites were detected in their feces. When 25 adult dogs reared in the facility of the same breeder were monitored, 18 dogs (72%), including the mothers of the infected puppies, were positive for cysts in the feces in spite of their normal appearance. Those results suggest that the poppies had been infected with giardian parasites when they were raised with their moth ers, and the stress of separation from the mothers may evoke clinical symptomology.
Metronidasole (Flagyl®, Shionogi & Co., Ltd., Osaka, Japan) was orally administered at a daily dose of 60 mg/kg for six consecutive days to all nine puppies and six of the 18 adults from which giardian parasites were detected. Consequently, giardian organisms were completely eliminated from all the puppies and five adults. One adult dog remained a carrier, but fecal cysts were markedly decreased relative to those before treatment.
