Treating single celled skin parasites

Ornamental fish showing cloudy skin spots and separate slimy layers are often infected by parasitic single celled organisms. The white spot pathogen in freshwater fish (Ichthyophthirius multifiliis), for instance, causes small pustules. Other single celled skin parasites such as Ichthyobodo sp., Chilodonella sp. or Piscinoodinium pillulare in fresh water also lead to tiny spots on the skin. These ectoparasites can be treated with the new sera Phyto med Protazid. It contains highly effective quinine (as hydrochloride), obtained from cinchona bark, as an active agent. Protazid is also suitable for treating velvet disease (Amyloodinium ocellatum) or Brooklynella hostilis in marine water. The agent solution contained in the 100 ml (3.38 fl.oz.) bottle is sufficient for 650 - 1,100 liters (171 - 290 US gal.) of water.
