Transient or permanent inhabitants : cultured internal microbiota of Cichlidogyrus thurstonae and Scutogyrus longicornis (Monogenea: Ancyrocephalidae) from Oreochromis sp.

Monogeneans, a class of parasitic platyhelminthes, are usually found on the surface of fish. When it feeds on its host, it harbours bacteria, which can survive in its gut. Occasionally, the monogeneans may cause damages on fish tissue while feeding and may allow secondary infection. The present...
