This study was carried out on 120 Oreochromis niloticus fish (60 wild and 60 cultured). The fish were randomly collected, from different areas of Assiut Governorate as well as from some fish farms. They were used to investigate the prevalence of Cryptosporidium and other zoonotic parasites in O. niloticus. Examination of gills, muscles and the contents of the gastrointestinal tract revealed highest parasitic infestation rate (80 %) in wild compared to (55 %) in cultured O. niloticus. The prevalence of the isolated parasites in wild and cultured O. niloticus was as follows: Cryptosporidium spp. 15.0 % and 23.3% respectively; Acanthocephela (Acanthocentius tilapae) 8.3 % and 9.2% respectively; microscopic encysted metacercariae 88.3% and 26.7 % respectively while macroscopic encysted metacercariae detected only in wild O. niloticus 40%. Killing factors (temperatures, solutions and processing methods) were studied on encysted metacercariae (EMC) in O. niloticus killing criteria followed the movability index (MI) from 1.000 within 24 hours. Muscle pieces containing viable EMC were incubated in different concentrations of NaCl, acetic acid or commercial vinegar at room temperature. The MI was ≤1 (killing effect) within 1, 2 hours for 30% and 20% of NaCl respectively and 1, 6 and12 hours for 5, 2.5 and 1.25%of acetic acid, respectively while commercial vinegar has MI ≥1 (no killing effect) at 5%.Storage of O. niloticus at (-10 C) resulted in killing the EMC after 12 hours of storage while storage at 5 ˚C for 24 hours has no killing effect. Dry salting of O. niloticus could kill the EMC within one hour of salt contact, while marination in 5 % acetic acid for one minute resulted in eradication of EMC after 2 hours of treatment with barely detected acetic acid odor and significant reduction in muscle pH (P < 0.05.).

“…Several dispersal events place them as a group of successful colonizers despite the variety of their definitive hosts, long migratory distances, climatic variations, and geographic barriers. This success would explain the small number of species that constitute the phylum Acanthocephala, which show accidental infections in hosts that are not part of the normal transmission route, including Homo sapiens Linnaeus, 1758 (Fujita et al., 2016; Haustein et al., 2010; Tada et al., 1983).…”

During Earth history, the development of geographic barriers resulted in the origin of sister species whose distributions reflect a history of geological or biotic discontinuity, isolation, and allopatric speciation (Hoberg & Brooks, 2010). Under this view, the biosphere represents a unifying model for exploring macroevolutionary and ecological processes that have driven biogeography and diversification, including complex host-parasite systems (Hoberg & Brooks, 2008). Manter (1966) was one of the first authors to recognize parasites as key elements in understanding the history of their hosts, and established their relevance as phylogenetic, ecological, and biogeographic indicators of their hosts. Host-parasite close interaction along an evolutionary continuum can influence the diversification rates of the organisms involved (Huyse et al., 2005; Rico-Hernández, 2011). This shared history can be reflected in congruent phylogenetic relationships (cophylogeny) by repeated cospeciation of the involved taxa, or in incongruent phylogenies because of host switching, independent speciation of the parasite (duplication), and sorting events (Clayton et al., 2004; Johnson et al., 2003; Page, 2003). Coevolutionary and biogeographic analyses may help provide a complete view of the diversification of parasites and hosts over time, since the distribution ranges of hosts are

“…There is only one unusual report of an immature acanthocephalan, probably Plagiorhynchus sp., retrieved from a gardener's eye in Kent, England. Most probably the parasite was accidentally transferred from the environment to the pateints's eye, possibly by his own hands [73] . Adult worms of this species are long known common parasite of amphibians in south-eastern Asia [74,75] .…”

Neglected rare human parasitic infections: Part III: Acanthocephaliasis

Human acanthocephaliasis is a zoonotic parasitic infection with acanthocephalan species. Reports documenting human infection with acanthocephalans are relatively rare in the literature. Nonetheless, man has been infected with acanthocephalans since ancient times. Despite their economic and medical significance, acanthocephalans were found to be good indicators of environmental pollution. This review summarizes current knowledge of acanthocephalans as human parasites and their beneficial uses.
