“…Clinical symptoms of cestodoses caused by adult worms are usually mild or even asymptomatic, the most common clinical signs being abdominal discomfort or pain, constipation, diarrhea and weakness; only extremely rarely has anemia or vitamin B12 deficiency been reported (Waeschenbach et al, 2017). Parasitism of some Brazilian fish, including B. capriscus, Genypterus brasiliensis Regan, 1903, Paralichthys isosceles Jordan, 1890, and Lophius gastrophysus Miranda-Ribeiro, 1915, by diphillobothriid larvae has been reported in papers on taxonomy, parasite ecology and hygienicsanitary conditions (Alves et al, 2005;Knoff et al, 2008Knoff et al, , 2011bFelizardo et al, 2010). In South America, Dibothriocephalus latus (Linnaeus, 1758) Lühe, 1899 (=Diphyllobothrium latum), Dib.…”

Balistes capriscus is an appreciated fish species in the state of Rio de Janeiro, Brazil, due its excellent quality flesh. The constant presence of helminth larvae in the abdominal musculature, viscera and serosa of individuals of the species has been the subject of complaints among local fish traders because of economic losses due to their repugnant aspect. Considering their hygienicsanitary importance and significance for collective health, the presence of helminth larvae was investigated in 44 individual fish of B. capriscus purchased from fish markets in the municipalities of Rio de Janeiro, Niterói, Campos dos Goytacazes and Cabo Frio, state of Rio de Janeiro, in 2017-2018. Cestode larvae, identified as Diphyllobothriidae gen. sp. and Callitetrarhynchus gracilis, were found parasitizing the abdominal cavity, abdominal musculature, mesentery and liver serosa. Nematode (Raphidascaridiidae) third-instar larvae, identified as Hysterothylacium deardorffoverstreetorum and Raphidascaris sp., were found parasitizing stomach, intestine, liver, spleen, liver serosa, mesentery and abdominal cavity. The highest parasitic indices were for Raphidascaris sp., with prevalence of 70.45%, mean intensity of 15.61, mean abundance of 11 and infection range of 1-76 specimens per host. Considerations of the zoonotic potential and hygienic-sanitary significance of these helminths are presented to increase food safety for consumers.

“…A small drop of aliquot of the suspension was withdrawn with help of plastic dropper and put in a clean, grease free glass slide and examined under a microscope using 10X and 40X objectives. MC were identified to the genus level following the previously described keys and manuals (Sohn 2009, Kiyan et al 2018, Knoff et al 2011. Photographs of MC were taken using an inverted microscope to which a digital camera was fitted.…”

. Fish-borne zoonotic parasites are a rapidly increasing health hazards for human in all over the world. There is a scarcity of information on the fish-borne zoonotic parasite infection in Bangladesh. The present study was aimed to investigate fish-borne helminth parasites in Bhola district. A total of 300 fresh fish samples were collected randomly from different local markets of Bhola district and transported to the laboratory of the Department of Parasitology, BAU. Fishes were homogenized and digested with pepsin-HCl solution for overnight and washed with NaCl solution for 8-9 times and then sediment was examined under a microscope to detect the presence of metacercariae/metacestode. Fishes were found to be infected with multiple infective stages of helminth parasites such as Opisthorchis sp., Clonorchis sp., Diphyllobothrium sp., Metagonimus sp. and Metorchis sp. In this study, 58% overall prevalence of fish-borne zoonotic parasites was recorded. About 80% metacercariae was found in Loitta (Harpadon nehereus) followed by 65% in Spotted snakehead (Channa punctata), 60% in Tilapia (Oreochromis nilolticus), 45% in Stinging catfish (Heteropneustes fossilis) and 24.28% in Indian carplet (Amblypharyngodon microlepis). The plerocercoid of Diphyllobothrium sp. were identified morphologically and was confirmed molecularly by PCR. This study indicates that fish-borne helminth parasites may pose a significant public health risk to the people of Bhola district.

“…A enfermidade foi confirmada com o exame parasitológico das fezes, sendo constatado a presença de ovos operculados do parasita (SANTOS; FARO, 2005). No Brasil há relatos do parasitismo em diversos estados como Rio de Janeiro (KNOFF et al, 2011), São Paulo (SAMPAIO et al, 2007, Espírito Santo, Belo Horizonte, Paraíba (OLIVEIRA et al, 2017) sendo todos relacionados diretamente com a ingestão de comida japonesa, seja de sushis ou sashimis de salmão cru.…”

“…Não há relatos do gênero Diphyllobothrium parasitando peixes de cultivo e de vida livre no Brasil. Um estudo realizado por Knoff et al, (2011) relatou a presença de larvas de cestódeos Diphyllabotriidea em peixes-sapo Lophius gastrophysus e afirma que mais estudos devem ser realizados em peixes brasileiros para procura de larvas plerocercóides. Na necropsia de um cachorro-do-mato Cerdocyon thous foi encontrado adultos de Diphyllobothrium mansoni fixado em intestino delgado, o qual foi identificado pela morfologia do estróbilo e dos ovos, pois o escoléx não foi encontrado (SANTOS et al, 2004).…”

O Brasil tem destaque na produção mundial de alimentos de origem animal. Entre estes alimentos está a carne de pescado que atualmente é proveniente tanto de produção comercial aquícola quanto da pesca extrativista. Com o aumento do consumo de peixes no Brasil e no mundo se torna importante a prevenção e o controle da ocorrência das Doenças Transmitidas por Alimentos (DTAs). Há diversos estudos relacionando a presença de bactérias em surtos alimentares transmitidos por pescados, principalmente de peixes adquiridos em feiras livres, porém há poucos estudos a respeito das parasitoses nesse tipo de carne sendo que os peixes podem abrigar diversos parasitas. Assim, o objetivo é informar os parasitas que podem provocar surtos alimentares pelo consumo de pescado tanto de cativeiro quanto de pesca extrativista. No Brasil, existe uma carência muito grande de dados epidemiológicos e consequente falta de diagnóstico tanto nos peixes de consumo quanto nos seres humanos consumidores de pescado. Com isto, o médico veterinário é um importante aliado como agente sanitário desempenhando um fundamental prevenindo e auxiliando assim, na diminuição dos riscos de disseminação dos parasitas aos seres humanos. Conclui-se que é importante o conhecimento das parasitoses zoonóticas transmitidas por pescado tanto por parte dos profissionais quanto pela população consumidora.
