Occurrence of Lipoptena mazama and Lipoptena guimaraesi (Diptera: Hippoboscidae) on gray brocket deer (Mazama gouazoubira) in southern Brazil.

The genus Lipoptena includes hematophagous insects of the family Hippoboscidae that parasitize different deer species. The present study aims to identify 19 flies that parasitize deer of the genus Mazama in the State of Paraná, Brazil. We analyzed 18 flies (Lipoptena mazamae) and 1 Lipoptena guimaraesi. This study expands the host list for L. guimaraesi, previously restricted to a single deer species (Ozotoceros bezoarticus).

SARS-CoV-2 Delta variant of concern in Brazil - multiple introductions, communitary transmission, and early signs of local evolution (preprint)

The dissemination of the Delta VOC in Brazil is still unclear, despite the frequent reports of isolated cases from different Brazilian states. In this report we characterize the dissemination of the Delta VOC in Brazil and where the introductions of this lineage fall within the global Delta phylogeny. We also examined the mutational profile of the largest clade within the Brazilian Delta VOCs, with a focus on samples which were obtained in the State of Sao Paulo, and especially in the city of Sao Paulo, the largest metropolis of South America, and a national and international transportation hub.
