Do the pattern and strength of species associations in ectoparasite communities conform to biogeographic rules?

Parasitol Res 2019 Feb 18. Epub 2019 Feb 18.

Wyler Department of Dryland Agriculture, French Associates Institute for Agriculture and Biotechnology of Drylands, Jacob Blaustein Institutes for Desert Research, Ben-Gurion University of the Negev, Sede Boqer Campus, Midreshet Ben-Gurion, Israel.

We tested whether biogeographic patterns characteristic of species diversity and composition may also apply to community assembly by investigating geographic variation in the pattern (PSA) (aggregation versus segregation) and strength of species associations (SSA) in flea and mite communities harbored by small mammalian hosts in Western Siberia. We asked whether (a) there is a relationship between latitude and PSA or SSA and (b) similarities in PSA or SSA follow a distance decay pattern or if they are better explained by variation in environmental factors (altitude, amount of vegetation, precipitation, and air temperature). We used a sign of a co-occurrence metric (the C-score) as an indicator of PSA and its absolute standardized value as a measure of SSA. Read More

Helminths protect against type 1 diabetes: effects and mechanisms.

Parasitol Res 2019 Feb 13. Epub 2019 Feb 13.

Department of Obstetrics and Gynecology, People's Hospital of Songzi City, Songzi, 434200, Hubei, China.

Type 1 diabetes (T1D) is an autoimmune disease in which cells of the immune system destroy pancreatic β cells, which secrete insulin. The high prevalence of T1D in developed societies may be explained by environmental changes, including lower exposure to helminths. Indeed, infection by helminths such as Schistosoma, Filaria, and Heligmosomoides polygyrus and their by-products has been reported to ameliorate or prevent the development of T1D in human and animal models.

Parasitol Res 2019 Jan 31. Epub 2019 Jan 31.

Molecular and Structural Biophysics Laboratory, Department of Biochemistry, North-Eastern Hill University, Shillong, 793022, India.

Fasciola gigantica is an important food-borne trematode responsible for the hepatobiliary disease, commonly known as fascioliasis. In F. gigantica, the glyceraldehyde 3-phosphate dehydrogenase (FgGAPDH) is a key enzyme of the glycolytic pathway and catalyzes the reversible oxidative phosphorylation of D-glyceraldehyde-3-phosphate (G-3-P) to 1,3-bisphosphoglycerate (1,3-BPG), with the simultaneous reduction of NAD to NADH.

Albendazole resistance induced in Ancylostoma ceylanicum is not due to single-nucleotide polymorphisms (SNPs) at codons 167, 198, or 200 of the beta-tubulin gene, indicating another resistance mechanism.

Parasitol Res 2019 Jan 29. Epub 2019 Jan 29.

Departamento de Parasitologia, L4 237, Laboratório de Parasitologia Molecular, Universidade Federal de Minas Gerais, Instituto de Ciências Biológicas, Avenida Presidente Antônio Carlos, 6627, Pampulha, CEP 31270-901, Belo Horizonte, Minas Gerais, Brazil.

Mass drug administration has been implicated as the major cause of drug resistance in nematodes of ruminants. Single-nucleotide polymorphisms (SNPs) at codons 167, 198, and 200 of the beta-tubulin isotype 1 gene are associated with albendazole resistance mechanisms. Although drug resistance is suspected to occur in nematodes of the same order, at present, there is no evidence of a strong correlation between these canonical SNPs and albendazole resistance in hookworms.
