Comparison of the Accuracy of Four Malaria Diagnostic Methods in a High Transmission Setting in Coastal Cameroon.

J Parasitol Res 2019 10;2019:1417967. Epub 2019 Mar 10.

The Biotechnology Centre, University of Yaoundé 1, Yaoundé, Cameroon.

Background: Despite recommendation from the World Health Organization that all malaria suspected patients undergo a parasitological confirmation using rapid diagnostic test or light microscopy prior to treatment, health facilities in remote malaria endemic settings sometimes resort to presumptive diagnosis of malaria for clinical management for various reasons. Following observation of this practice, we undertook a cross-sectional study aimed at comparing presumptive diagnosis based on axillary temperature, SD Bioline™ rapid test, and light microscopy as strategies for malaria diagnosis in the coastal region of Mutengene in the South West of Cameroon with the overall goal of supporting improved malaria diagnosis at local levels.

Methodology: Venous blood from 320 participants was used to detect the presence of malaria parasite using SD Bioline™ mRDT and Giemsa stained microscopy or spotted on filter paper for PCR amplification of the 18s rRNA gene of following standard procedures. Read More

The dense granule protein 8 (GRA8) is a component of the sub-pellicular cytoskeleton in Toxoplasma gondii.

Parasitol Res 2019 Apr 4. Epub 2019 Apr 4.

Departamento de Bioquímica, Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional (CINVESTAV-IPN), Avenida IPN N°2508. Sn Pedro Zacatenco, Del. Gustavo A. Madero, 07360, Mexico City, CP, Mexico.

After host cell invasion, Toxoplasma secretes a variety of dense granule proteins (GRA proteins) from its secretory dense granules, which are involved in the biogenesis of the parasitophorous vacuole (PV). TgGRA8 is predicted to contain proline-rich domains, which are structural features of some cytoskeleton-related proteins. In agreement with this observation, previous proteomic analyses revealed the presence of TgGRA8 in the Toxoplasma sub-pellicular cytoskeleton. Read More

Revealing trophic transmission pathways of marine tapeworms.

Parasitol Res 2019 Mar 15. Epub 2019 Mar 15.

Ecology Degree Programme, Otago University, PO Box 56, Dunedin, 9054, New Zealand.

Parasites are important components of natural systems, and among their various roles, parasites strongly influence the flow of energy between and within food webs. Over 1000 tapeworm species are known to parasitise elasmobranchs, although full life cycles are resolved for fewer than 10 of them. The lack in resolution stems from the inability to distinguish larval from adult stages using morphology alone. Read More

Antarctophthirus microchir infestation in synanthropic South American sea lion (Otaria flavescens) males diagnosed by a novel non-invasive method.

Parasitol Res 2019 Mar 14. Epub 2019 Mar 14.

Institute of Parasitology, Biomedical Research Center Seltersberg (BFS), Justus Liebig University Giessen, Schubertstr. 81, 35392, Giessen, Germany.

Antarctophthirus microchir is a sucking louse species belonging to the family Echinophthiriidae and has been reported to parasitize all species of the subfamily Otariinae, the sea lions. Former studies on this ectoparasite mainly required fixation, immobilization, or death of host species and especially examinations of adult male sea lions are still very rare. Between March and May 2018, adult individuals of a unique "urban" bachelor group of South American sea lions (Otaria flavescens) living directly in the city of Valdivia, Chile, were studied regarding their ectoparasite infestation status.

Heterologous overexpression of active hexokinases from microsporidia Nosema bombycis and Nosema ceranae confirms their ability to phosphorylate host glucose.

Parasitol Res 2019 Mar 13. Epub 2019 Mar 13.

Laboratory of Microbiological Control, All-Russian Institute for Plant Protection, Podbelskogo shosse, 3, Pushkin, St. Petersburg, 196608, Russia.

The secretion of hexokinases (HKs) by microsporidia followed by their accumulation in insect host nuclei suggests that these enzymes play regulatory and catalytic roles in infected cells. To confirm whether HKs exert catalytic functions in insect cells, we expressed in E. coli the functionally active HKs of two entomopathogenic microsporidia, Nosema bombycis and Nosema ceranae, that cause silkworm and honey bee nosematoses.

Evaluation of targeted copper sulfate (CuSO) application for controlling swimmer's itch at a freshwater recreation site in Michigan.

Parasitol Res 2019 Mar 8. Epub 2019 Mar 8.

School of Public Health, University of Alberta, Edmonton, Alberta, Canada.

Swimmer's itch has historically been controlled by applying copper sulfate (CuSO) to lakes as a way to eliminate snails that serve as the intermediate hosts for swimmer's itch-causing parasites. CuSO is still sometimes applied specifically to areas of lakes where swimmer's itch severity is high. It is unclear whether targeted application of chemical molluscicides like CuSO is effective for controlling swimmer's itch. Read More
