Samuel Wanji, Dowo O Akotshi, Maurice N Mutro, Tepage Floribert, Tony O Ukety, Peter J Diggle, Jan H Remme Parasites & Vectors 2012, 5:25 (2 February 2012)
Abstract | Provisional PDF

Editor’s summary
This study was designed to validate RAPLOA in two regions in the North East and South West of the Democratic Republic of Congo. In each selected community, 80 people above the age of 15 years were interviewed for a history of eye and parasitologically examined for the presence and intensity of L. loa infection. The results confirmed the findings of the original RAPLOA study and the methodology is recommended for the assessment of loiasis endemicity in areas targeted for ivermectin treatment by lymphatic filariasis and onchocerciasis control programmes.

Editor’s summary
We investigated the prevalence of Giardia duodenalis infection and identified possible associated risk factors in a healthy paediatric population from Portugal. We highlight the high prevalence of G.duodenalis in these children, as well as the parents¿ education level as the main risk factor. Of interest, we also found an association between G. duodenalis and Helicobacter pylori infections. Image: Giardia duodenalis cysts stained by FICT.

Editor’s summary
We show for the first time that the cervid filaria Setaria tundra is widespread in southern Germany and transmitted by various mosquito species, except Culex spp. In contrast, a second, yet unidentified filarial species, was exclusively found in Culex spp. in Baden-Wurttemberg, and is likely to be a bird parasite. We found no zoonotic filariae. Image: A female house mosquito, Culex pipiens s.l., seeking an overwintering shelter in September 2011.

We describe a morphologically atypical Leishmania isolate, obtained from a cutaneous leishmaniasis patient in Brazil. In axenic cultures, atypical promastigotes grow as round cells with very short or absent flagella. We show that, in spite of the defective flagella, they can infect macrophages and are able to establish infections in mice and sand flies. Image: Atypical promastigote of a L.

We established a novel loop-mediated isothermal amplification targeting the 529 bp repeat element (529 bp-LAMP) to detect Toxoplasma gondii DNA in the blood samples of experimental mice infected with tachyzoites of the RH strain. Due to its simplicity, sensitivity and cost-effectiveness for common use, we suggest that this assay should be used as an early diagnostic tool for health control of toxoplasmosis.
