“…Immediately after blood collection, the fish were euthanized by neural pithing [ 21 ]. In necropsies the intestines were removed and fixed in 10% buffered formalin solution, dehydrated in increasing series of ethanol, diaphanized, embedded in paraffin, cut into serial sections 4 μm thick using a Leica RM2255 automated microtome, and stained with hematoxylin-eosin (H&E) [ 22 ] and periodic acid-Schiff (PAS) [ 23 ]. Images were captured using a Leica DM 1000 microscope coupled to a computer and using the Leica Application Suite software version 1.6.0 for image capture.…”

The FDA-approved drug ivermectin is applied for treatments of onchocerciasis and lymphatic filariasis. The anticancer and anti-viral activities have been demonstrated stressing possibilities for the drug repurposing and therefore new information on high dosage safety is on demand. We analyzed in vivo tissue responses for high doses of ivermectin using Corydoras fish as animal model. We made intestinal histology and hematologic assays after oral administration of ivermectin transported with polyelectrolytes formulation. Histology showed any apparent damage of intestinal tissues at 0.22-170 mg of ivermectin/kg body weight. Immunofluorescence evidenced delocalization of Myosin-Vb at enterocytes only for the higher dose. Hematology parameters showed random variations after 7 days from administration, but a later apparent recover after 14 and 21 days. The study evaluated the potential of high doses of oral administration of ivermectin formulation, which could be an alternative with benefits in high compliance therapies.

“…Procamallanus (Spirocamallanus) inopinatus Travassos, Artigas & Pereira, 1928, is a camallanid that was initially described as Leporinus spp., in the Mogi-Guaçu River, in the state of São Paulo, Brazil (Travassos et al, 1928). This nematode species of freshwater fish has distribution in South American countries such as Brazil, Argentina, Peru, Paraguay and Venezuela (Moravec et al, 1997;Moravec, 1998;Hamann, 1999;Takemoto et al, 2009;Chemes & Takemoto, 2011;Kohn et al, 2011;Gonçalves et al, 2016;Almeida-Berto et al, 2018;Rivadeneyra et al, 2020). Despite this wide biogeographic distribution, the life cycle of P. (S.) inopinatus remains unknown, since no detailed studies on the association between this nematode and its host fish have yet been carried out.…”

“…This nematode feeds on nutrients that have been processed by the host fish and it can cause intestinal damage due to inflammation, desquamation, hypertrophy, formation of fibrous capsules, loss of villi and necrosis in the muscle, mucous and submucous layer. These processes can lead to host fish malnutrition and anemia (Gaines et al, 2012;Rivadeneyra et al, 2020). Infections by P. (S.) inopinatus can affect both wild and farmed fish populations (Takemoto et al, 2009;Kohn et al, 2011;Gaines et al, 2012).…”

This study used information about Procamallanus (Spirocamallanus) inopinatus Travassos, Artigas & Pereira, 1928 that had been published over a period of more than 90 years to investigate the infection and distribution patterns of this nematode in teleost freshwater fish in Brazil. This study was carried out using 181 samples from 82 fish species in 19 families within the five orders, with predominance of Characiformes species (71.6%). We organized a matrix-based parasite-host system in which the fish species were classified in different trophic levels and parasitic infection parameters according data available on host fish species with different life histories and geographic distributions across Brazilian hydrographic basins. Procamallanus (S.) inopinatus showed prevalence ranging from low to moderate, low abundance, low intensity, typically aggregated dispersion, and preferential infection of the hosts' gastrointestinal tract. There was difference in prevalence between detritivorous, omnivorous, carnivorous and piscivorous hosts, but no difference in intensity and abundance was found due to similarity in the communities of this endoparasite among the host fish species. The geographic distribution of this parasite encompasses the river of the Amazon, Paraná, São Francisco, North Atlantic, South Atlantic and Eastern basins. Lastly, suggestions regarding the life cycle of P. (S.) inopinatus, with its potential intermediate hosts, were discussed.

“…Estudos sobre os parâmetros sanguíneos e histopatológicos são úteis no diagnóstico de doenças em peixes, bem como nas investigações sobre a extensão e compreensão dos danos causados por parasitos nos diversos tecidos dos hospedeiros, em indivíduos e populações de peixes parasitados (Marinho et al, 2015;Rocha et al, 2018;De Oliveira et al, 2019;Lehmann et al, 2020;Rivadeneyra et al, 2020). As avaliações desses parâmetros ajudam a entender os processos fisiológicos nos hospedeiros para manutenção da homeostase orgânica frente a ação de diferentes grupos de parasitos, assim como os efeitos deletérios dos parasitos em seus hospedeiros (Lehmann et al, 2020;Mazur et al, 2020;Sousa et al, 2020).…”
