Anthelmintics for people with neurocysticercosis.

Cochrane Database Syst Rev 2021 06 1;6:CD000215. Epub 2021 Jun 1.

Institute of Neurology, Madras Medical College, Chennai, India.

Background: Neurocysticercosis is a parasitic infection of the central nervous system by the larval stage of the pork tapeworm and is a common cause of seizures and epilepsy in endemic areas. Anthelmintics (albendazole or praziquantel) may be given alongside supportive treatment (antiepileptics/analgesia) with the aim of killing these larvae (cysticerci), with or without corticosteroid treatment. However, there are potential adverse effects of these drugs, and the cysticerci may eventually die without directed anthelminthic treatment. Read More

Hacettepe University, School of Health Services, Medical Laboratory Programme, Ankara, Turkey.

Some of the pathogenic microorganisms have been associated with cancer due to the activation of cancer precursors in the host because of the inflammatory processes. Additionally, some other pathogens prevents the tumor formation by creating an anti-neoplastic immune response which has been reported to stop the development of cancer. Cystic echinococcosis (CE) or cyst hydatid disease (CHD) is a zoonotic infection caused by the larval form of Echinococcus granulosus sensu lato in humans. Read More

First description of peritoneal and pleural metacestodosis caused by Mesocestoides vogae in a European wild cat (Felis silvestris silvestris).

Parasitol Res 2021 Jun 31;120(6):2275-2279. Epub 2021 Mar 31.

Faculty of Veterinary Medicine, University of Zagreb, Heinzelova 55, Zagreb, Croatia.

Tapeworms of the genus Mesocestoides (Cestoda: Cyclophyllidea: Mesocestoididae) are still enigmatic to scientists, due to their high morphological variability, low host specificity, and unknown details of their life cycle. They are found worldwide, with carnivorous mammals as the main definitive hosts, and the disease is potentially zoonotic. After ingestion by a definitive host, the tetrathyridium can occasionally migrate through the intestinal wall and reach the peritoneal cavity or abdominal organs causing peritoneal metacestodosis.

Hidden diversity of the most basal tapeworms (Cestoda, Gyrocotylidea), the enigmatic parasites of holocephalans (Chimaeriformes).

Sci Rep 2021 Mar 9;11(1):5492. Epub 2021 Mar 9.

Institute of Parasitology, Slovak Academy of Sciences, Košice, Slovak Republic.

Gyrocotylideans are evolutionary ancient parasitic flatworms, and like their hosts-a relict group of holocephalan fishes (Chimaeriformes)-they are considered to be "living fossils" of a vanished past. However, the species diversity, host associations and biogeography of these most basal tapeworms are poorly known. Herein, we provide evidence of a conspicuous contrast between the genetic and morphological data based on an examination of newly collected and properly processed Gyrocotyle specimens (hologenophores) isolated from holocephalans off Taiwan and Argentina.
