“…Finally, in agreement with Munro (1953) Hynes (1955, Schmidt (1964) Kennedy (1972) Baudoin (1975 and Moore (1983) we consider it possible that benefits accrued to a parasite castrating or otherwise reducing host reproduction may include, besides increased host viability, an increase in energy available because of reduced host reproductive expenditure. As an example of this, we observed significantly higher glycogen levels in parasitized females, although it is not possible to state if this glycogen comes from pathophysiological effects induced by the parasite or if it is stored in the cysticercoids prior to its investment in the final parasitic form following metamorphic development.…”

Some aspects of Artemia biology affected by cestode parasitism

et al. 1991

Artemia individuals from a wild population, bearing cestode cysticercoids (Hymenolepididae) were kept in the laboratory during four months to observe influences of the parasite on the host biology. No differences were found between parasitized and unparasitized shrimps regarding final adult size. The higher survival of parasitized animals suggests that parasitism is not pathogenic. The most dramatic effect was host castration. Parasitized individuals showed higher total lipid levels, probably linked to carotenoid pigments conveying a red color to parasitized shrimps.

“…In Bulgaria, this species has been reported from various birds, most frequently from the Eurasian blackbird (Turdus merula L.) and the common starling (Sturnus vulgaris L.) (Dimitrova et al 2000). Its cystacanths develop in terrestrial isopods; as demonstrated by previous studies (Schmidt and Olsen 1964, Moore 1983, Lisitsina 1993, Lisitsina and Tkach 1994, Lisitsina and Sharpilo 1996, Levri and Coppola 2004, the species range of intermediate hosts exhibits substantial geographical variation. Since no studies on the life cycle of P. cylindraceus have been carried out in South-East Europe, the aim of the present study is to reveal the range of intermediate hosts of this parasite species in this region.…”

“…In view of the abundance of T. squamuliger in the habitats examined, it can be assumed that it has much more significant role for the circulation of P. cylindraceus than Armadillidium vulgare. Though reported many times as intermediate host of P. cylindraceus (Sinitsin 1929;Dollfus and Dalens 1960;Schmidt and Olsen 1964;Dappen andNickol 1981, cited after Schmidt 1985;Moore 1983;Lisitsina 1993;Lisitsina and Tkach 1994;Lisitsina and Sharpilo 1996;Coady and Nickol 2000), the latter species has been represented with very low numbers in the examined habitats and, therefore, its role is probably of secondary importance.…”

“…Experimental studies using Armadillidium vulgare, Porcellio scaber Latreille, 1804 and P. laevis Latreille, 1804 as intermediate hosts were carried out by Schmidt (1964, cited after Schmidt 1985, Schmidt and Olsen (1964), Wanson and Nickol (1975) and Nickol and Dappen (1982) in North America and by Lisitsina (1993) in the Ukraine. The present results demonstrate for the first time the role of Trachelipus squamuliger as intermediate host of P. cylindraceus and constitute a new host record.…”

Occurrence of cystacanths of Plagiorhynchus cylindraceus (Acanthocephala) in the terrestrial isopods Trachelipus squamuliger and Armadillidium vulgare (Oniscidea) in Bulgaria

In total, 2097 individuals of Trachelipus squamuliger and 20 individuals of Armadillidium vulgare from four habitats (three woodland sites and one pasture) in the region of Stara Zagora, Bulgaria, were examined for the presence of cystacanths of Plagiorhynchus cylindraceus, a common acanthocephalan parasite of passerine birds. In T. squamuliger from woodland habitats, cystacanths were found with prevalence 4.0-9.3%, intensity 1-5 (mean 1.22-1.57) and mean abundance 0.057-0.113. No significant differences were observed between infections in males and females of T. squamuliger. None of the T. squamuliger individuals from the pasture examined was infected. Out of 48 infected females of T. squamuliger, only one had developed eggs (in agreement with previous studies revealing the negative effect of the cystacanths on the development of female gonads of woodlice). One individual of A. vulgare was infected with a single cystacanth. The occurrence of P. cylindraceus in T. squamuliger is a new host record.

“…Uniformly, however, woodlice, mainly Armadillidium vulgare, and other isopods function as intermediate hosts (Schmidt and Olsen 1964;Nickol and Dappen 1982;Moore 1983;Levri and Coppola 2004;Dimitrova 2009). …”

The avian acanthocephalan Plagiorhynchus cylindraceus (Palaeacanthocephala) parasitizing the European hedgehog (Erinaceus europaeus) in Europe and New Zealand

et al. 2009

The palaeacanthocephalan Plagiorhynchus cylindraceus is a common intestinal parasite of passerine birds, which can also occur parenterally or in the intestinal tract of mammals, often as an invading species in many countries worldwide. In this survey, introduced hedgehogs (Erinaceus europaeus, n = 183) killed in New Zealand during a biocontrol campaign and conspecifics (n = 174) that had died in hedgehog rehabilitation centers in Germany and Britain were examined for this parasite. In New Zealand, P. cylindraceus is recorded for the first time here, in the vicinity of Auckland. In Europe, prevalences ranged from 4.2% up to 47.6%, while in New Zealand, only 1.6% (Auckland 7.9%). Most of the worms occurred inside the peritoneal cavity where they had partly degenerated. Since hedgehogs are seldom preyed upon in continental Europe but often become traffic victims, we hypothesize that the worms inside them, whether extra- or intraperitoneally, contribute to the abundance and persistence of the parasite by being ingested by scavenging birds. Accordingly, we consider P. cylindraceus as a "modern parasite" taking advantage of two aspects of global change: anthropogenic promoted transmission (road kills) and the transcontinental spread of infected intermediate and/or final hosts caused by humans.
