The double stranded RNA (dsRNA) virus Leishmaniavirus (Totiviridae) was first described in Leishmania guyanensis and L. braziliensis (LRV1), and more recently from L. major and L. aethiopica (LRV2). Parasites bearing LRV1 elicit a higher pro-inflammatory profile, arising through activation of Toll like receptor 3(TLR3) interacting with the viral dsRNA. LRV1 is most common in Leishmania from the...

Claviradulomyces xylopiae sp. nov. is introduced for a fungus occurring in association with abnormal (enlarged, spongy) lenticels of Xylopia sericea (Annonaceae), a common tree of the Atlantic forest and Cerrado ecosystems in Brazil. This is the second species described in the genus and, although it is morphologically distinct from the type species, C. dabeicola from West Africa, it possesses t...

We describe a new fluorogenic assay for the identification of species and intraspecies groups within the Leishmania donovani complex. The assay combined (1) 2 polymerase chain reactions targeting the 2 cysteine proteinase b isogenes and (2) a fluorescence-resonance energy transfer/melting curve analysis of the polymorphisms within a 31-nt region. All strains within the L. donovani complex were ...
