The aim of this study was to evaluate the prevalence, abundance and average intensity of plerocercoids (PLs) of Adenocephalus pacificus in the most important commercial fish species from the Peruvian coast. A total of 28 species of fish were sampled and 12 017 specimens were analysed. The presence of PLs of A. pacificus were determined from Peruvian anchovy (Engraulis ringens), lorna drum (Sciaena deliciosa), striped mullet (Mugil cephalus), horse mackerel (Scomber japonicus), Peruvian rock sea bass (Paralabrax humeralis) and cabinza grunt (Isacia conceptionis) with a prevalence of 0.55, 24.96, 0.56, 1.79, 1.53 y 3.94%, respectively. Three different types of scolex of A. pacificus PLs, like as spherical, lanceolate, heart-shaped were identified, regardless of the host, area and sampling period.

The aim of this study was to evaluate the antibacterial activity of methanol and methanol-chloroform extracts of tegument, gonad and viscera of Pattalus mollis. Fifty specimens were collected in the Pucusana Bay, Peru, dissected longitudinally through the ventral area of ​​the tegument and the internal organs (viscera, gonad) were removed. The samples were dried to 10% moisture, milled and stored in freezing. The extracts were obtained by maceration using methanol and chloroform. The in vitro evaluation was performed using the broth microdilution method, the extracts were diluted in seven concentrations (3.9-250 mg/ml) and evaluated against Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 14775 and Vibrio alginolyticus ATCC 17749. The methanol extract showed bacterial inhibition against the three bacteria, demonstrating a bactericidal and bacteriostatic effect against Gr...
