Nematodes of the Anisakidae family were studied in Sardinella aurita and Mugil curema caught in Venezuelan coastal waters and sold in Cumaná’s main market in Sucre state, Venezuela. Fifty fish of each species were analyzed, examined, dissected and their internal cavities, cephalic organs, abdominal trunk and caudal regions wereinspected. They were also debrided, and muscles dissected in search of nematodes in their third larval stage (L3) through simple visual examination. Detected nematode parasites were mechanically extracted from the organs and tissues for identification and classification at the genus level. The M. curema species was the only fish found to be infected with parasites. Distinct parasitic species were observed in 48/50 (96%) of the M. curema specimens analyzed. The prevalence of helminths in these specimens included nematodes of the Anisakidae family, Acanthocephala ...

Toxocariasis is a human infection caused by the larvae of the nematodes Toxocara canis (Werner, 1782) or Toxocara cati (Schrank, 1788), which are parasitic in animals, and represents a serious public health problem. The objective of this study was to investigate the information and prevalence of parasitic toxocariasis in the state of Sucre, Venezuela, particularly in the municipalities of Montes and Sucre, in communities considered vulnerable due to social and economic deficiencies within the epidemiological/sanitary monitoring. In these municipalities, there are many stray dogs living near homes and maintaining contact with other domestic dogs. The seroprevalence of T. canis was evaluated through the ELISA method. A seroprevalence of IgG anti-T. canis was obtained in the parish of San Juan of 90.12% and in the parish of Cumanacoa of 82.14%. In the parish of San Juan, when evaluating the...
