Description de

Description et différenciation de l’adulte de Hymenolepis cerberensis n. sp. (Cestoda : Hymenolepididae), parasite intestinal de la Musaraigne étrusque, Suncus etruscus (Savi, 1822) (Insectivora : Soricidae : Crocidurinae) capturée sur les communes de Banyuls-sur-Mer et Cerbère (Pyrénées-Orientales, France). La nouvelle espèce est caractérisée par la taille des individus gravides et la présence de 18-21 crochets rostraux de 18,5-20 µm de longueur et de filaments autour de l’embryophore. La composition générale de la faune de Cyclophyllidea parasites de S. etruscus est analysée. Il s’agit de trois Hymenolepis peu spécialisés à scolex du même type et d’un Pseudhymenolepis, avec absence d’espèces inermes et sans rostre. Le caractère oioxène des Cestodes parasites d’espèces de Suncus appuient la validité du genre Suncus. La ressemblance des Cestodofaunes des genres Suncus et Crocidura suggère une relation phylétique très étroite entre ces deux genres de Crocidurinae

Immunoblot Patterns of Taenia asiatica Taeniasis

Differential diagnosis of Taenia asiatica infection from other human taeniases by serology has been tested. An enzyme-linked immunoelectrotransfer blot (EITB) was applied to subjected human sera and tapeworm materials. Thirty-eight proteins reactive to serum IgG were observed between 121 and 10 kDa in adult worms, and more than 22 serum-reactive components between 97 kDa and 21.5 kDa were observed in eggs of T. asiatica. Antigens of adult T. asiatica revealed immunoblot bands between 120 and 21.5 kDa against T. asiatica infected sera. Antigens of adult Taenia saginata revealed 110-100, 66, 58-56, and 46 kDa immunoblot bands against T. asiatica infected sera. Antigens of adult Taenia solium also revealed 99-97, 68-66, and 46 kDa bands against T. asiatica infected sera. The immunoblot band of 21.5 kDa exhibited specificity to T. asiatica

Epidemiological understanding of Taenia tapeworm infections with special reference to Taenia asiatica in Korea

In endemic areas of Taenia tapeworms in Korea, most of the reports showed that T. saginata was dominant over T. solium, but eating pigs is the dominant habit over eating cattle. Why do they have more T. saginata despite lower consumption of beef? This problem actually has long been recognized but until recently there has been no intensive trial to give a scientific explanation on this epidemiological enigma. By summing up the data published between the years 1963 and 1999, the ratio of armed versus unarmed tapeworms in humans was estimated at approximately 1:5. The ratio of pig-eaters versus cattle-eaters, however, was approximately 5:1. This inconsistency could be explained with the recently described T. asiatica, which infects humans through the eating of pig's viscera. We re-evaluate the importance of the consumption of visceral organ of pigs, leading us to an improved epidemiological understanding of the T. asiatica infection together with co-existing T. saginata and T. solium in Korea

Surveillance and diagnosis of zoonotic foodborne parasites

Foodborne parasites are a source of human parasitic infection. Zoonotic infections of humans arise from a variety of domestic and wild animals, including sheep, goats, cattle, camels, horses, pigs, boars, bears, felines, canids, amphibians, reptiles, poultry, and aquatic animals such as fishes and shrimp. Therefore, the implementation of efficient, accessible, and controllable inspection policies for livestock, fisheries, slaughterhouses, and meat processing and packaging companies is highly recommended. In addition, more attention should be paid to the education of auditors from the quality control (QC) and assurance sectors, livestock breeders, the fishery sector, and meat inspection veterinarians in developing countries with high incidence of zoonotic parasitic infections. Furthermore, both the diagnosis of zoonotic parasitic infections by inexpensive, accessible, and reliable identification methods and the organization of effective control systems with sufficient supervision of product quality are other areas to which more attention should be paid. In this review, we present some examples of successful inspection policies and recent updates on present conventional, serologic, and molecular diagnostic methods for zoonotic foodborne parasites from both human infection and animal-derived foods.Peer reviewe
