Marsh deer (Blastocenrs dichotomus) were captured for a research progam in
Brazil and maintained in quarantine stations. After 60 days, fleas were det
ected on animals and identified as Ctenocephalides felis felis. Elimination
of the infestation was difficult. Animal treatment with a fipronil-based c
ompound was effective, and subsequently captured animals were treated proph
ylactically. Some animals remained infested, and some died from the infesta
tion.
