Molecular identification of Wolbachia from the filarial nematode Mansonella ozzardi

Parasitology Research, 2001
Mansonella ozzardi, a filarial parasite of humans in Latin America, has been shown to harbour intracellular bacteria not yet identified. Here we show that these bacteria, like those of other filarial nematodes, belong to the genus Wolbachia (alpha 2 Proteobacteria; Rickettsiales). Their unambiguous placement in the Wolbachia group was shown by 16S rDNA

A field trial of a PCR-based Mansonella ozzardi diagnosis assay detects high-levels of submicroscopic M. ozzardi infections in both venous blood samples and FTA® card dried blood spots [PDF]

Parasites & Vectors, 2015
Background Mansonella ozzardi is a poorly understood human filarial parasite with a broad distribution throughout Latin America. Most of what is known about its parasitism has come from epidemiological studies that have estimated parasite incidence using

Mansonella ozzardi infection treated by levamisole

, 1986
La administración de levamisol a la dosis para adultos, de 150 mg durante 2 a 3 meses, estuvo asociada la disminución y finalmente a la desaparición de microfilarias circulantes de Mansonella ozzardi. No se presentaron reacciones secundarias a la droga y la eosinofilia circulante, sirvió como indicador de la presencia de microfilarias.
