“…In our experimental study we selected Trichobilharzia szidati Neuhaus, 1952 as a model organism because knowledge on exact total or average numbers of cercariae released from a snail host is rather ambiguous and quantitative estimates on its cercariae productivity is entirely lacking, although it is probably the most studied model bird schistosome [ 18 , 25 ]. Cercariae of T .…”

Digenean trematodes are common and abundant in aquatic habitats and their free-living larvae, the cercariae, have recently been recognized as important components of ecosystems in terms of comprising a significant proportion of biomass and in having a potentially strong influence on food web dynamics. One strategy to enhance their transmission success is to produce high numbers of cercariae which are available during the activity peak of the next host. In laboratory experiments with 13 Lymnaea stagnalis snails infected with Trichobilharzia szidati the average daily emergence rate per snail was determined as 2,621 cercariae, with a maximum of 29,560. During a snail’s lifetime this summed up to a mass equivalent of or even exceeding the snail’s own body mass. Extrapolated for the eutrophic pond where the snails were collected, annual T. szidati biomass may reach 4.65 tons, a value equivalent to a large Asian elephant. Emission peaks were observed after the onset of illumination, indicating emission synchronizing with the high morning activities of the definitive hosts, ducks. However, high cercarial emission is possible throughout the day under favorable lightning conditions. Therefore, although bird schistosomes, such as T. szidati constitute only a fraction of the diverse trematode communities in the studied aquatic ecosystem, their cercariae can still pose a considerable risk for humans of getting cercarial dermatitis (swimmer's itch) due to the high number of cercariae emitted from infected snails.

“…Other liver-hosting Posthodiplostomum species are associated with liver damage that can cause digestion dysfunction and consequently, malnutrition in infected fish (Osorio-Sarabia et al 1986;López-Hernández et al 2018). Although at the fish farming level, it is known that black spot disease is produced by diplostomids (Alvarez- León, 2007;Horák et al 2014), taxonomic studies are required to determine the species existing in Colombia.…”

En Colombia, las ictiozoonosis causadas por helmintos son poco estudiadas y permanecen desatendidas desde el sector de la salud pública, representando una interacción por explorar en términos de biodiversidad y salud. Caquetia kraussi es un pez nativo de Colombia y Venezuela de importancia económica, debido a su alto consumo por parte de comunidades locales. Esta investigación registra la fauna de helmintos parásitos asociados a C. kraussi en un sistema de laguna costera en el Caribe colombiano. En febrero y diciembre de 2020 se examinaron 32 especímenes de C. kraussi, de los que se recolectaron 242 helmintos en los estadíos de metacercaria y adulto. Los parásitos incluyeron metacercarias de los tremátodos Clinostomum sp., Austrodiplostomum sp., dos morfoespecies de Posthodiplostomum spp. y adultos de Oigogonotylus andinus además de adultos del acantocéfalo (Eoacanthocephala) Neoechinorhynchus sp. Estos resultados indican que C. kraussii actúa como hospedador definitivo de O. andinus. y Neoechinorhynchus sp., y como hospedador intermediario de Clinostomum sp., Posthodiplostomum spp. y Austrodiplostomum sp. Se reporta por segunda vez una población de O. andinus en Colombia y la ocurrencia de una morfoespecie del género Neoechinorhynchus que podría ser un reporte nuevo para Colombia. Además del aporte al conocimiento de la diversidad de helmintos asociados a peces, los resultados de esta investigación podrían ser aprovechados para generar recomendaciones para el manejo y control de helmintiasis en sistemas piscícolas artificiales que se surten de afluentes naturales y favorecen el establecimiento de hospederos y parásitos.
