Ocurrencia de camalánidos (Nematoda: Camallanidae) en peces hospedadores de la Amazonía peruana

Camallanids are nematodes that have been reported to parasitize different fish species in South America and can compromise the health of those species bred in captivity for fish farming and ornamental purposes. To date, in Peru, there are few studies related to camallanid parasitism in fish, so the main objective of this study was to report and identify species of this group of parasites present in 20 species of fish collected in the Peruvian Amazonia. Samples were analyzed through tissue and organ dissection methods for macroscopic evaluation and subsequent parasitic morphological and morphometric evaluation. Six species of camallanids were identified infecting the internal organs of analyzed fish: Paracamallanus amazonensis, Spirocamallanus krameri, Spirocamallanus iheringi, Procamallanus (Spirocamallanus) inopinatus, Procamallanus (Spirocamallanus) juana and Procamallanus (Spirocamallanus) pintoi.
