“…(P.) longa were found in mullets from Samborombón Bay, located 550 km northeast of the Bahía Blanca estuary (Martorelli et al 2012). The present study, along with the reports of Martorelli et al (2012) and Santos et al (2013), represents a warning about the potentially major impact of this parasite on public health in South America. We assume that the life cycle of A.…”

“…Simões et al (2010) elucidated the life cycle of this widespread species; which uses mullets as second-intermediate hosts and birds and mammals, including man, as definitive hosts. Ascocotyle (P.) longa is one of the causative agents of heterophyiosis, an emerging fish-borne disease of humans, contracted by the consumption of raw mullet (Martorelli et al 2012). Recently, metacercariae of A.…”

Larval trematodes infecting the snail Heleobia australis (Cochliopidae) from the Bahía Blanca estuary, Argentina were surveyed for two years. A total of 7,504 snail specimens was dissected and the larval stages of 15 different trematodes were recovered and examined morphologically. These larvae included four species that had previously been reported from H. australis in Brazil, Uruguay, and Argentina: the heterophyid Ascocotyle (Phagicola) longa and the microphallids, Maritrema bonaerense, Maritrema orensense, and Microphallus simillimus. Three other species, the echinostomatid Stephanoprora uruguayensis, the microphallid Levinseniella cruzi, and the psilostomid Psilochasmus oxyurus are reported here for the first time as parasites of H. australis. Eight other trematodes found in H. australis are described and placed in the appropriate superfamilies, families or genera (Cryptogonimidae, Apocreadiidae, Aporocotylidae, Notocotylidae, Haploporidae, Renicolidae, Himasthla, and Renicola). The prevalence of the trematode taxa infecting H. australis in the Bahía Blanca estuary was low (<3%) with a single exception (M. simillimus; >20%). Microphallidae were the richest and the most prevalent family, probably because of the high abundance of crabs -the second-intermediate hosts of certain microphallid species -and the considerable diversity of gulls. Here we compare the parasite assemblage found in the H. australis from Bahía Blanca estuary with other parasite assemblages infecting Heleobia spp. and other rissooids from the rest of the world.

“…(P.) longa was not reported in adult mullets, but have been mentioned parasitizing juvenile mullets by Carnevia & Speranza (2003) and Lado et al (2013) from Uruguayan coast of La Plata River and , Martorelli et al (2012) and Montes et al (2013), in Argentinean waters. In this work we increased the distribution between different sizes of mullets analyzed by Martorelli et al (2012). In both sites studied, the prevalence of A (P) longa increased as the mullets parasitized got bigger, and the mean abundance and mean intensity remained similar within each size for the same site.…”

ABSTRACT. Mugil liza Valenciennes, 1836 is an economically important food fish and has been recommended for aquaculture in South America. A total of 278 fishes were collected in the spring and summer of 2009 and 2010. These fish were sorted into sample groups according to their size class. We used Bayesian statistics and 95% credible intervals for each parameter tested were calculated. Fish studied harbored a total of 15 different species of parasites. Diversity of parasite species found on Mugil liza was greatest at the S.R.C. collection site, but evidenced a lower species richness than at A.R. site. The 1st size fishes of both sites evidenced greater parasite diversity than either 2nd or 3rd size fish. Differences observed could be explained by the different use of habitat types at the two sites or differential susceptibility to infection by parasites. The dominance of D. fastigata influenced observed results of lower community diversity indexes. New works elucidating different parasite life cycles within juvenile and adults of M. liza in Argentina, promise to be important for determining the risk of the parasitism by zoonotic metacercariae A. (P.) longa and use of this fish as food and an economic resource, and the possible use of mullet parasites in other promising fields as indicators of biodiversity, and/ or water contamination. KEYWORDS.Bayesian statistic, Ascocotyle, Dicrogaster, Hymenocotta, Phyllodistomum. RESUMEN. Análisis ecológica y comparativa de parásitos en juveniles deMugil liza (Pisces, Mugilidae) de dos sitios en la baía Samborombón, Argentina. Mugil liza, Valenciennes, 1836 es un pez de importancia comercial y ha sido recomendado en Sudamerica para la acuicultura. Los peces se distribuyeron en grupos de acuerdo con la talla. Usamos estadística Bayesiana e intervalos de credibilidad del 95% para cada parámetro calculado. Los peces alojaron un total de 15 especies parasitarias. La diversidad de las especies parasitas de M. liza fue mayor en el sitio de colecta S.R.C., pero evidencio una menor riqueza especifica que en A.R. La 1er talla de los peces de ambos sitios evidencio una mayor diversidad parasitaria que la 2da o 3er talla. Las diferencias observadas se pueden explicar por un uso diferente del hábitat en los dos sitios o a una susceptibilidad diferente a la infección por los parasitos. La influencia de la dominancia de D. fastigata resulta en el menor índice de diversidad de la comunidad. Nuevos trabajos que diluciden los diferentes ciclos de vida de los parásitos en los juveniles y adultos de M. liza en Argentina, prometen ser importantes para determinar el riesgo del parasitismo de la metacercaria zoonotica A. (P.) longa y el uso de este pez como alimento, una fuente económica y el posible uso de los parásitos de la lisa en otros promisorios campos como indicadores de biodiversidad y/o contaminación acuática.

Fish-borne heterophyid trematodes are known to have a zoonotic potential, since at least 30 species are able to infect humans worldwide, with a global infection of around 7 million people. In this paper, a ‘state-of-the-art’ review of the South American heterophyid species is provided, including classical and molecular taxonomy, parasite ecology, host-parasite interaction studies and a list of species and their hosts. There is still a lack of information on human infections in South America with undetected or unreported infections probably due to the information shortage and little attention by physicians to these small intestinal flukes. Molecular tools for specific diagnoses of South American heterophyid species are still to be defined. Additional new sequences of Pygidiopsis macrostomum, Ascocotyle pindoramensis and Ascocotyle longa from Brazil are also provided.
