| contents | Parasites and hepatic histopathological lesions in lisa (Mugil incilis) from Totumo mash, North of Colombia Jesús Olivero V Bárbara Arroyo S Ganivet Manjarrez P Veterinaria fishes nematode trematode Anisakiasis zoonoses (Source: CAB ) Objective. To assess the levels of parasitism by nematodes and trematodes, as well as the hepatic histopathological alterations present in Mugil incilis (Lisa) from Totumo marsh, North of Colombia. Materials and methods. Between July 2004 and June 2005, 500 fish were collected at Totumo Marsh (75°16’W and 10°44 ́N), North of Colombia. Morphometric and parasitic parameters were determined for each specimen, and the hepatic histopathological status of the liver was assessed by analyzing liver slides stained with hematoxylin and eosin. Results. Nematode larvae isolated from Mugil incilis corresponded to Contracaecum spp. Parasite prevalence was 60.49%. Parasitic mean abundance and mean intensity were 4.8±1.05 and 7.02±1.49, nematodes per fish, respectively. The correlation between nematode mean abundance and fish length was significant and positive (r=0.525, p<0.0001), but negative for condition factor (r=-0.109, p=0.014). Hepatic histopathological analysis revealed the presence of encapsulated trematode larvae as the main finding. However, the presence of inflammation, granulomas, steatosis and necrosis, were also registered as secondary alterations. Conclusions. Lisas collected at Totumo Marsh are parasitized with nematodes and trematodes. These fish have different histopathological lesions in the liver tissue, being the most important the presence of trematode encapsulated cyst that generate inflammatory reactions, and negatively correlate with morphometric markers of fish health. 2013 artículo científico 0122-0268 https://www.redalyc.org/articulo.oa?id=69325829001 en http://www.redalyc.org/revista.oa?id=693 Revista MVZ Córdoba application/pdf Universidad de Córdoba Revista MVZ Córdoba (Colombia) Num.1 Vol.18 |
