Curitiba, PR, Brasil.Paraná state presents the fourth highest number of accumulated cases of hantavirus pulmonary syndrome in Brazil. To map the risk areas for hantavirus transmission we carried out a study based on rodent trapping and determined the anti-hantavirus seroprevalence in these animals and in the inhabitants of these localities. Overall seroprevalence in rodents and humans were 2.5% and 2.4%, respectively. Eighty-two percent of the seropositive rodents were genetically analyzed. Phylogenetic analyses revealed that hantaviruses from rodent samples cluster with Araucária (Juquitiba-like) or Jaborá hantavirus genotypes. The Jaborá strain was identified in Akodon serrensis and Akodon montensis, whereas the Araucária strain was detected in Oligoryzomys nigripes, Oxymycterus judex, A. montensis, and Akodon paranaensis, with the latter species being identified for the first time as a natural host. These findings expose the complex relationships between virus and reservoirs in Brazil, which could have an impact on hantavirus transmission dynamics in nature and human epidemiology

Incidences of poisonings due to Chlorophyllum molybdites in the state of Paraná, Brazil

Three recent cases of poisoning by Chlorophyllum molybdites, including the first one known from Brazil, have been reported from the state of Paraná. A morphological description of the material causing the first poisoning was provided and the associated case history has been described in detail. An overview of this species' distribution in Brazil is given.<br>Três casos recentes de envenenamento por Chlorophyllum molybdites, incluindo o primeiro caso conhecido para o Brasil, são relatados do Estado do Paraná. Uma descrição morfológica do material que causou o primeiro envenenamento é apresentada, assim como uma narrativa detalhada do respectivo caso clínico. É, ainda, fornecido um panorama da distribuição desta espécie no Brasil
