Schistosoma spindale
Summary

Species of fluke

Schistosoma spindale is a species of digenetic trematode in the family Schistosomatidae. It causes intestinal schistosomiasis in the ruminants.

The distribution of Schistosoma spindale includes Sri Lanka, India, Bangladesh, Thailand, Malaysia, and Laos.{{Cite journal

The tegument of Schistosoma spindale under scanning electron microscope was studied in 1983.{{Cite journal

The first intermediate host is a freshwater snail Indoplanorbis exustus that may be the sole natural intermediate host for Schistosoma spindale (and other two Schistosoma species) on the Indian sub-continent. One snail can produce up to 7,000 cercariae in one day.{{Cite journal

[[Cercariae]] can infect cattle in water environment.

The cercariae usually infect some hairy host (low host specificity) in shallow and muddy waters.

The definitive hosts of Schistosoma spindale are (mainly) ruminants and Schistosoma spindale cause intestinal schistosomiasis of ruminants (Artiodactyla, Ruminantia). Surveillance for cattle schistosomiasis is generally inadequate and the literature is limited, but some idea of the problem can be gained from past small scale studies. For a diagnosis there is need to find eggs of Schistosoma spindale in feces. Surveys in Sri Lanka revealed prevalence of Schistosoma spindale of 31.2% (of 901 cattle),{{Cite journal

Other hosts of Schistosoma spindale include:

  • Bandicota indica
  • Rattus argentiventer
  • Rattus rattus diardii
  • Rattus tiomanicus jalorensis

Schistosoma spindale has been implicated of human cercarial dermatitis in India and in Malaysia.
