SOME STUDIES ON ICHTHYOPHONOSIS AMONG MARINE FISHES WITH REFERENCE TO MYCOLOGICAL SIGNIFICANCE OF CAUSATIVE AGENT

Nematode worm Anisakis sp is the causative agent of anisakiasis, a zoonosis which continues to be a health problem in humans, globally. Its clinical spectum varies from mild to very severe and always connected with sea fishes, one important source of nutrition for the community that cannot be ignored. In addition, consumer’s behavior and lifestyle in processing and consuming sea fishes also have has the potency as the predisposing factor for its transmission and clinical manifestations. This review article aimed to describes recent global data on anisakiasis and its occurrence in marine fishes of Indonesian waters and the risk of transmission in the community.

Muscle Lesions

Kudoa is a myxozoan that causes myoliquefaction in marine fishes. Most of species only affect fish, but a K. septempunctata outbreak was reported in 358 people. Although many species of Kudoa are known, none was described in Brachyplatystoma filamentosum, Brachyplatystoma rousseauxii, Mugil curema, Plagioscion squamosissimus or Oxydoras niger until now. Due to the economic cost of eliminating seafood presenting myxozoan lesions, this study aimed to describe lesions found at necropsy and histopathology, as well as to detect this myxozoan by molecular techniques. For this purpose, were sampled 85 fish of the following species: Brachyplatystoma filamentosum, Brachyplatystoma rousseauxii, Mugil curema, Plagioscion squamosissimus, and Oxydoras niger from Colares and Vigia, Pará, Brazil. Necropsies were carried out to describe lesions and molecular techniques (PCR and sequencing) were applied for identification. Although muscle lesions were not observed at necropsy, histopathology revealed bacterial colonies, coagulative necrosis, dystrophic calcification, eosinophils, hemorrhage, parasitic cysts, protozoan, and vacuolization. After sequencing, K. shiomitsui (GENBANK: LC128646) was identified as the causative agent of fishes infection. Also, high parasitism of this myxozoan was observed in fishes sampled, i.e., 90 % in Colares and 100% in Vigia.

The protozoan parasite Entamoeba histolytica is the causative agent of amebiasis in man. The trophozoite or motile form is a highly dynamic and pleomorphic cell with a great capacity to destroy tissues. Moreover, the parasite has the singular ability to phagocytize a variety of different live or death cells. Phagocytosis of red blood cells by E. histolytica trophozoites is a complex phenomenon related with amebic pathogenicity and nutrition.
