The exceptional fossil site of Las Hoyas (upper Barremian, Cuenca, Spain) yields abundant small to medium vertebrate coprolites, hindering the search for parasites. We studied the contents of 29 coprolites that were previously classified into distinct morphotypes. Several parasitic eggs were retrieved from two of these coprolites, confirming the second record of digenea trematode eggs and nematode (ascaridid) eggs from an Early Cretaceous locality. The cylindrical coprolite containing anisakid eggs was likely produced by a crocodylomorph as the parasite host, whereas the bump-headed lace coprolite indicates the role of a fish as an intermediary or definitive host of the trematodes and ascaridids. These trace and body fossils show that the Las Hoyas 126–129 Ma lacustrine ecosystem documents the early connection between basal Gonorynchiformes fish and digenetic trematodes.

“…Adult Anisakidae worms lay eggs (oviposition) in the stomach or in the intestine of the definitive host. Then, the eggs are released from the host through faecal matter 58 . The eggs become embryonated in the water, and the infective L3 larvae hatch from eggs as free-swimming larvae that are ingested by crustaceans or fishes 44 , 59 .…”

“…Los nematodos de la familia Anisakidae comprenden al menos nueve géneros, de los cuales Anisakis, Pseudoterranova y Contracaecum, han cobrado importancia por producir infecciones zoonóticas al consumir carne de pescado cruda o insuficientemente cocinada (1). La especie Contracaecum multipapillatum (Von Drasche 1882) posee un ciclo de vida que se desarrolla en ambientes acuáticos, parasitando a diferentes especies de crustáceos en sus primeras fases larvarias y a peces en su tercer estadio larvario, siendo esta la fase infectante para los hospederos definitivos que son aves piscívoras, en las que se da la reproducción sexual y liberación de huevos hacia el medio ambiente acuático (2,3,4). Los reportes que asocian los nemátodos anisákidos con infecciones accidentales en el ser humano son también escasos en Latinoamérica (7).…”

Contracaecum multipapillatum infecta peces como hospedadores intermediarios y al ser humano como hospedador accidental por consumo de carne de pescado cruda o semi cocinada. Este riesgo para la salud humana hace importante determinar su prevalencia, intensidad de infección y ubicación anatómica en peces destinados al consumo mediante pesca artesanal; y la influencia de parámetros físicoquímicos del agua sobre la infección en peces. Se recolectaron 214 peces en 6 ríos de Cañas, Guanacaste, Costa Rica y 203 peces en el Lago de Izabal y Río Dulce, Izabal, Guatemala. En los sitios de pesca se tomaron parámetros físicoquímicos del agua (temperatura, pH y oxígeno disuelto). La prevalencia de infección fue 16.8% y 25.1% en Guanacaste e Izabal, respectivamente, encontrándose 105 larvas de tercer estadio (L3) en 36 peces de Guanacaste y 135 L3 en 51 peces de Izabal. Se observó afinidad de L3 por órganos viscerales (22.4% en Guanacaste – 25.1% en Izabal) y menor por tejido muscular (2.0% en Guanacaste – 1.0% en Izabal). La intensidad de infección directamente proporcional con la talla y peso de los peces (una larva en 13 peces con peso y talla media de 66.7 g y 17.5 cm en Guanacaste, y siete peces de 214.9 g y 28.4 cm en Izabal; y 14 larvas en un pez de 148.8 g y 24 cm en Guanacaste y 12 larvas en un pez de 260 g y 40 cm en Izabal). No se observó asociación entre parámetros fisicoquímicos del agua y susceptibilidad de peces a infección.

“…The infections by nematodes in the mullets are produced mainly by species of the Anisakidae family (Castellano et al, 2017;Valles-Vega et al, 2017); these are roundworms (Ajala & Fawole, 2014;Gaber et al, 2015). Sometimes the presence of these parasites in the mullet does not generate important physiological alterations (Dione et al, 2014;Maldonado & Godoy, 2014).…”

“…Sometimes the presence of these parasites in the mullet does not generate important physiological alterations (Dione et al, 2014;Maldonado & Godoy, 2014). However, when they are caused, the observed effects may be oxidative stress, tissue damage, immunosuppression and endocrine disruption, which affect the population of mullet and the fishing industry (Valles-Vega et al, 2017).…”

Coastal lagoons are an important component of the Gulf of California as they are considered natural ecosystems with high productivity and home to species of regional economic interest such as the striped mullet (Mugil cephalus), which, for its eating habits tends to present parasitism. The objective of the present work was to identify and determine the number of nematode parasites in the striped mullet in three lagoon systems (Navachiste, La Reforma, and Ceuta) in coastal areas of the southern Gulf of California. Thirty Mugil cephalus were randomly obtained from each of the lagoon systems. From each fish was obtained the total length, weight and condition factor (FC), next was dissected to be analyzed hepatosomatic index (HSI) and determine by direct count the prevalence, average intensity and average abundance of nematode; nematodes are identified taxonomically and molecularly. The nematode parasites found to belong to the genus Contracaecum of the family Anisakidae in all the fish sampled the parasitic prevalence was 67%. The nematode parasites found by sex indicated that 77% of the striped mullet females analyzed were parasitized, while the males presented 59%. The CF obtained was 1.17- 4.07, and the HSI ranged between 0.85 and 1.45; the average intensity for nematodes was 7.45, and the average abundance was 4.97, demonstrating that Contracaecum multipapillatum is the main nematode parasite present in all lagoon systems the southern Gulf of California.
