Protozoan Disease of Freshwater Fishes: Advances and Needs

  • Glenn L. Hoffman


A brief review of the most important protozoan problems in the U.S.A. is given. More precise identification of protozoa is needed in order to better control the most pathogenic species. Because of the dangerous Myxosoma cerebralis, Ceratomyxa shasta, and Henneguya of catfish, other myxosporideans are being watched more closely. Better control methods are needed. Ichthyophthirius multifiliis continues to be a world-wide problem; better therapy is needed.

Ein Kurzer Uberblick der wichtigsten protozoischen Probleme in den U.S.A. ist gegeben. Eine genauere Identifizierung der Protozoen ist notwendig, um die meisten Arten von Krankheitserregeru zu kontrollieren. Wegen des defahrlichen Mysoxoma cerebralis, Ceratomyxa shasta und Henneguya von Katzenfischen, hat man andere Myxosporideans naher beobachtet. Bessere Methoden zur Kontrolle sind notwendig. Ichthyopthirius multifiliis bleibt weiterhin ein weltweites Problem; eine bessere Therapie ist notwendig.
