Synopsis
CAPC Recommends Fecal sedimentations should be used for diagnosis of Platynosomum fastosum in infected cats. Cats should not be allowed to hunt in order to prevent ingestion of intermediate hosts.
Species
Platynosomum fastosum (syn. Platynosomum concinnum ) – lizard poisoning fluke.
Disease
Severe disease and clinical signs are often absent in cats with few worms (<125). Severity of disease is proportional to the number of flukes and duration of infection.
Prevalence
Platynosomum fastosum is a liver fluke of cats in Florida, other areas of the southeastern United States, and Hawaii. Prevalence has been reported at 15-85% in tropical and subtropical environments.
Diagnosis
Eggs can be found in feces by fecal sedimentation. Eggs are dense and rarely float.
Treatment
Evans and Green (1978) reported efficacy using praziquantel at 20mg/kg. Eggs were still visible in feces 9 weeks post treatment.
Control and Prevention
Cats should not be allowed to hunt to prevent ingestion of the intermediate hosts.
