“…In addition to the economic loss to farmers, many of the parasites, particularly trematodes, are also of zoonotic importance. Eating raw or improperly cooked or processed fish is the main source of these infections for humans, and this has been reported from various geographical regions (PARK et al, 2009). The World Health Organization (WHO) has estimated that the number of people currently infected with fish-borne trematodes exceeds 18 million, and many more are at risk (WHO, 1995).…”

The present study was the first attempt to survey the diversity of fish zoonotic parasites in the southern region of Saudi Arabia, particularly the Najran area, from October 2012 to October 2013. Approximately 163 fish representing seven species (two of freshwater fish and five of marine fish) were examined for fish-borne trematode metacercariae using the compression technique, and for zoonotic nematode larvae. Adult flukes were obtained from cats experimentally infected with the metacercariae on day 25 post-infection The prevalence of each parasite species was recorded. The parasites found belonged to two taxa: Digenea (Heterophyes heterophyes and Haplorchis pumilio) in muscle tissue; and nematodes (larvae of Capillaria sp.) in the digestive tract. The morphological characteristics of the fish-borne trematode metacercariae and their experimentally obtained adults were described. This is the first report of these parasites in fish in Saudi Arabia. Moreover, Myripristis murdjan presented higher prevalence of Capillaria sp. infection (22.7%), while Haplorchis pumilio was the dominant metacercarial species (7.9%). Although the number of documented cases continues to increase, the overall risk of human infection is slight. The increasing exploitation of the marine environment by humans and the tendency to reduce cooking times when preparing seafood products both increase the chances of becoming infected with these parasites. Furthermore, our results indicate that certain fish production systems are at risk of presenting fish zoonotic parasites, and that control approaches will benefit from understanding these risk factors.

“…This parasite was transmitted by eating raw or undercooked fish, which is linked to cultural factors of certain human populations (Park et al, 2009), and was found attached to the human mucous layer of larynx and pharynx. However, although the prevalence of these trematodes was very low in these hosts (P. pardalis and P. disjunctivus), it was not recommended to consume undercooked meat fish.…”

Parasites of two coexisting invasive sailfin catfishes (Siluriformes: Loricariidae) in a tropical region of Mexico

Currently many species of Amazon sailfin catfishes (Loricariidae) have been introduced to wild environments outside their native range. There is, however, little knowledge about their role as vectors of parasites that can infect native fish or even humans through its consumption. The aim of the present study was to determine the parasitic fauna of the invasive sailfin catfish species Pterygoplichthys pardalis (leopard pleco) and P. disjunctivus (vermiculated pleco) from freshwater systems in the southeast of Mexico. Four ectoparasite species were found in P. pardalis (1 protozoan: Ichthyophthirius multifiliis; 2 monogeneans: Urocleidoides vaginoclastrum and Heteropriapulus heterotylus; 1 digenean: Clinostomum sp.), and only one in Heteropriapulus disjunctivus (H. heterotylus). No endoparasites were found. Ichthyophthirius multifiliis, U. vaginoclaustrum and Clinostomum sp., were considered as rare species (prevalence <5%) since they were found in a single individual of P. pardalis. H. heterotylus was the only species shared among both host species and it occurs throughout the year. This monogenean species represents 96% of total parasites recorded in P. pardalis and 100% in P. disjunctivus. Monthly values of prevalence, intensity and abundance of H. heterotylus in both host species showed important intra-annual variations, but not differ significantly between both hosts. Actualmente muchas especies de peces conocidos como plecos o peces diablo (Loricariidae) han sido introducidas en ambientes silvestres fuera de su área de distribución natural. Sin embargo, hay poco conocimiento acerca de su papel como vectores de parásitos que puedan infectar a los peces nativos o incluso los seres humanos a través de su consumo. El objetivo del presente estudio fue determinar la fauna parasitaria de las especies de plecos Pterygoplichthys pardalis (pleco leopardo) y P. disjunctivus (pleco vermiculado) en sistemas de agua dulce del sureste de México. Fueron encontradas cuatro especies de ectoparásitos en P. pardalis (1 protozoario: Ichthyophthirius multifiliis; 2 monogeneos: Urocleidoides vaginoclastrum y Heteropriapulus heterotylus; 1 digeneo: Clinostomum sp.) y una en P. disjunctivus (H. heterotylus). No se encontraron endoparásitos. Ichthyophthirius multifiliis, U. vaginoclaustrum y Clinostomum sp. fueron consideradas como especies raras (prevalencia <5%), ya que estuvieron en un solo individuo de P. pardalis. Heteropriapulus heterotylus fue la única especie compartida entre ambas especies de peces y que estuvo presente durante todo el año, y representó el 96% del total de parásitos registrados en P. pardalis y el 100% en P. disjunctivus. La prevalencia, intensidad media y abundancia media de H. heterotylus mostraron importantes variaciones intra-anuales en ambas especies de peces, pero no difirió significativamente entre ambos hospederos.

“…Laryngopharyngitis, (Table 1). [4][5][6] Perch, which is a brackish-water fish, is a medically important intermediate host for C. complanatum, and human infections may occur if an affected fish is consumed raw. 7,8 This fluke attaches to the mucosa, causing a parasite-induced laryngopharyngitis in humans; however, to the best of our knowledge, there has not been any cases involving serious complications associated with C. complanatum infection.…”

“…[4][5][6] However, the number of cases may be underestimated because this type of parasite may not be well known or as frequently reported; it is possible for C. complanatum infection to be misdiagnosed as anisakiasis. 11,12 In conclusion, laryngopharyngitis resulting from C. complanatum infection is a rare occurrence.…”

“…2,3 The first Korean case of human infection was published in 1995; two additional cases have been reported to date. [4][5][6] C. complanatum is a parasitic flatworm-known as a fluke-that remains in an encysted resting state (metacercaria) inside its second intermediate host, causing an infection in the final host. 7,8 Although an infection by C. complanatum is extremely rare in humans, laryngopharyngitis can occur when raw fish (i.e., the second intermediate) is ingested (i.e., the final host).…”

A 46-year-old woman visited our hospital presenting throat pain and globus sensation. The symptoms occurred seven days after eating raw perch and mullet. An endoscopy under sedation showed a fluke-with an approximate length of 4.8 mm and width of 1.5 mm-on the left aryepiglottic fold, with active motility on the mucosa. It was extracted from the larynx using biopsy forceps and was identified as Clinostomum complanatum. To the best of our knowledge, this is the second reported case of human infection with Clinostomum complanatum diagnosed and treated by an endoscopy in Korea. Endoscopy is a useful tool in the diagnosis and treatment of patients at risk for parasitic infections complaining of throat pain. (Korean J Gastroenterol 2017;69:177-180)
