Intestinal amoebiasis in Heckel discus Symphysodon discus - a case report
This case is reported with the intention of highlighting the presentation of primary intestinal amoebic disease in Heckel discus Symphysodon discus. The morphology of the parasites and the pathological changes seen using light microscopy were essential. In fresh samples of intestinal content we discovered numerous amoeba-like cells. The trophozoite measures 18.6 x 10.2 mm while the cyst is 11-2...
متن کاملIsoenzyme electrophoretic patterns in discus fish (Symphysodon aequifasciatus Pellegrin, 1904 and Symphysodon discus Heckel, 1840) from the Central Amazon.

متن کاملSpeciation in Thaparocleidus (Monogenea: Dactylogyridae) Parasitizing Asian Pangasiid Catfishes
The phylogeny of monogeneans of the genus Thaparocleidus that parasitize the gills of Pangasiidae in Borneo and Sumatra was inferred from molecular data to investigate parasite speciation. The phylogeny of the Pangasiidae was also reconstructed in order to investigate host-parasite coevolutionary history. The monophyly of Thaparocleidus parasitizing Pangasiidae was confirmed. Low intraspecies m...
متن کاملHistopathological study of parasitic infestation of skin and gill on Oscar (Astronotus ocellatus) and discus (Symphysodon discus)
Histopathology provides a rapid method to detect effects of irritants and pathogens in different organs and it can be considered as the indicator for abnormal condition for fish environment. The present study was initiated to record the histopathological lesions of gill and skin associated with external parasites in two common aquarium fish, Oscar (Astronotus ocellatus) and Discus (Symphysodon ...
