We used a combination of morphological, molecular and biological data to characterize novel Henneguya (Myxozoa) species infecting the Amazonian prochilodontid Semaprochilodus insignis or “kissing prochilodus”, popular food fish aquarium in Brazilian Amazon. Twenty-one S. were caught live from Tapajós river, Pará State, Brazil, then examined for myxozoan infections. Cysts observed connective tis...

Although most Myxozoa species of the genera Ceratomyxa and Ellipsomyxa have been described in marine hosts worldwide, an increasing diversity has reported infecting South American freshwater fish, mainly Amazonian waters. The present study deals with two myxozoan ceratomyxids parasitizing gallbladder ornamental cichlids fish: amazonensis is identified from a new host—Geophagus altifrons; while ...

Myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. The classification of myxosporeans is generally based on the morphology of their myxospores. Without molecular data, it is very difficult to identify new or existing species. DNA sequence information is therefore, a prerequisite to taxonomic and phy...
