“…Haplorchis taichui, Haplorchis pumilio, Stellantchasmus falcatus, Centrocestus caninus and Procerovum sp. were reported to be as the cercarial stage of the intestinal trematode in family Heterophyidae [18][19][20][21][22][23][24][25] . The identification of the morphology of cercariae were similar to those described by previous reported [8,16,20] .…”

“…(Jesus and Manso, 2010), M. tuberculatus can act as a vector of trematode parasites, which can affect wildlife and humans (Abilio and Watanabe, 1998), becoming a risk to the native aquatic biota and it can be a danger to the public health. There are reports of infected M. tuberculatus in several drainages in Brazil (Bogéa et al, 2005;Paula-Andrade et al, 2012;Pinto and Melo, 2013), however, the environmental impact of the parasite remains unknown (Pinto and Melo, 2013). Lernaea cyprinacea is a species that has no host specificity (Eiras et al, 2010), which increases the risk of infestation in the tanks.…”

Aquarium trade is one of the most important pathways of biological invasion. Much attention has been given to target introduced species, but little is discussed on the associated bycatch ones. The aim of this paper is to analyze the risk of invasion by non-commercial invertebrates using aquarium stores as a model. Monthly visits to eight stores in Aracaju (Sergipe State) were performed from April to September 2011. Inspections were carried out and questionnaires were applied to owners and employees of the establishments. Two non-native species were identified, Melanoides tuberculatus (Gastropoda: Thiaridae) and Lernaea cyprinacea (Crustacea, Copepoda). Sixty-two specimens of M. tuberculatus were found among the aquatic plants in one of the stores, while L. cyprinacea was collected in four establishments parasitizing Carassius auratus, Hypostomus sp., Poecilia latipinna, Poecilia sphenops, Poecilia reticulata and Xiphophorus hellerii. The interviews that have been done with owners and employees revealed that none of the stores has submitted fishes and plants to quarantine, and the disposal of wastewater is directly into the sewer system. It is necessary to adopt preventive measures such as a quarantine period for fishes and the creation of a warning about the dangers of biological invasions or aquarium dumping for aquarium hobbyists to mitigate the risk of invasion.

“…A popular and frequently exported fish Xiphophorus maculatus, also known as platy fish (family Poecilidae), is susceptible to a number of parasite species, including digenetic trematodes in their metacercarial stage, which use the fish as their second intermediate host (Thilakaratne et al 2003, Piazza et al 2006, Garcia et al 2009. Infections are associated with fish mortality, decreased feeding rate and increased susceptibility to predation which result in significant economic losses in the industry (Crowden and Broom 1980, Brassard et al 1982, Scholz 1999, WHO 2002, reviewed by Mitchell et al 2005a, Shoaibi Omrani et al 2010, Paula-Andrade et al 2012. Some of these parasites have also a zoonotic potential and may be considered a public health threat, if inadequately processed fish are consumed (WHO 1995, Chai and Lee 2002, Keiser and Utzinger 2005, Rim et al 2013.…”

Ornamental fish, Xiphophorus maculatus, were imported from Singapore to Denmark for distribution to local aquarists. Importers observed lethargic and erratic swimming patterns among fish and forwarded a total of 30 fish for pathological examination to a university diagnostic service. All fish were diagnosed infected with encysted Centrocestus sp. metacercariae in gills (prevalence of 100% and mean intensity of 454.5 ± 161.9 parasites per fish). Metacercariae were identified by morphological and molecular methods. Cysts (mean length 163.3 ± 13.7 µm and mean width 113.3 ± 10.6 µm) contained a bent metacercaria with an X-shaped excretory bladder. PCR amplification of a rDNA region (5.8S rRNA gene, ITS-2, 28S rRNA gene) and subsequent sequencing confirmed the diagnosis. Metacercariae were found in gill filaments adjacent to the cartilage associated with cartilage hypertrophy, epithelial and mucous cell hyperplasia, clubbing and lamellar fusion. Host cell encapsulation of cysts comprised several layers of leucocytes, chondroblast-like and fibroblast-like cells. The observations raise concerns with regard to veterinary inspection and quarantine procedures. The zoonotic potential of these trematodes and a possible spread of the parasites in natural habitats in Europe should be regarded as a public health issue. So far, several cases of human infections have been reported only in Asia, but the potential intermediate host snail, Melanoides tuberculata, has been recorded in Germany. Accordingly, establishment of the parasite in Europe with climate changes should be considered a risk.
