1. First serologic evidence of human hantavirus infection in Alagoas State in Northeastern Brazil
Abstract INTRODUCTION: Hantavirus cardiopulmonary syndrome (HCPS) is rare in Northeastern Brazil. METHODS: Prospective surveillance was conducted over a two-year period in Alagoas State, Northeastern Brazil. The prevalence of anti-hantavirus N-antigen IgM and IgG in human serum samples was determined by enzyme-linked immunosorbent assay testing. RESULTS

2. Seropositivity diagnosis for hantavirus in Jataí, Goiás State, Brazil
Abstract INTRODUCTION: Emerging diseases are of great interest, especially those associated with high mortality rates such as hantaviruses. We aimed to conduct a seroepidemiological survey to determine the levels of hantavirus infection. METHODS: In-house enzyme-linked immunosorbent assay (ELISA) was used to detect specific antibodies. RESULTS: Of the

3. Development of a novel plaque reduction neutralisation test for hantavirus infection
In the Americas, hantaviruses cause severe cardiopulmonary syndrome (HCPS) with a high fatality rate. Hantavirus infection is commonly diagnosed using serologic techniques and reverse transcription-polymerase chain reaction. This paper presents a novel plaque reduction neutralisation test (PRNT) for detecting antibodies to Brazilian hantavirus. Using PRNT, p

4. Prevalence of antibody to hantaviruses in humans and rodents in the Caribbean region of Colombia determined using Araraquara and Maciel virus antigens
We tested sera from 286 agricultural workers and 322 rodents in the department of Córdoba, northeastern Colombia, for antibodies against two hantaviruses. The sera were analysed by indirect ELISA using the lysate of Vero E6 cells infected with Maciel virus (MACV) or the N protein of Araraquara virus (ARAV) as antigens for the detection of antibodies against

5. Serologic survey of hantavirus in a rural population from the northern State of Mato Grosso, Brazil
INTRODUCTION: Hantavirus is a genus of ribonucleic acid (RNA) viruses included in the family Bunyaviridae. Hantaviruses are rodent-borne zoonoses that, in the last 18 years, became an emergent public health problem in the Americas, causing a severe cardiopulmonary syndrome. This disease has no specific treatment and has a high case fatality. The transmission

6. Detection of the first incidence of Akodon paranaensis naturally infected with the Jabora virus strain (Hantavirus) in Brazil
We characterised hantaviruses circulating in different Akodon rodent species collected in midwestern Santa Catarina (SC), southern Brazil, where the Jabora hantavirus (JABV) strain was first identified in Akodon montensis. Genetic and phylogenetic analyses based on a partial S segment indicated that, in SC, Akodon paranaensis and A. montensis carried the sam

7. Circulation of hantaviruses in the influence area of the Cuiabá-Santarém Highway
We describe evidence of circulation of hantaviruses in the influence area of the Santarém-Cuiabá Highway (BR-163) in the Brazilian Amazon through the prevalence of specific antibodies against hantaviruses in inhabitants living in four municipalities of this area: Novo Progresso (2.16%) and Trairão (4.37%), in state of Pará (PA), and Gua-rantã do Norte (

8. Montagem de um pseudo-hantavírus quimera, contendo a nucleoproteína do vírus Araraquara e as glicoproteínas do vírus Andes, em sistema baculovírus / Assembly of a chimeric hantavirus-like particle, containing the Araraquara nucleoprotein and the Andes glycoproteins, expressed in baculovirus system
Hantaviruses, members of the Bunyaviridae family, are the infectious agents responsible for Hemorrhagic Fever with Renal Syndrome and the Hantavirus Cardiopulmonary Syndrome. The viral genome is composed by three segments of single-stranded negative-sense RNA, designated as S, M and L, which encode, respectively, the nucleoprotein, the G1 and G2 glycoprotein

9. Aspectos geoambientais e epidemiológicos em áreas de transmissão da hantavirose no Distrito Federal : estudo de caso - São Sebastião 2004 a 2008
The Hantaviruses have worldwide distribution and are important public health problem. The epidemiology of Hantaviruses in Brazil shows that is increasing every year the number of cases that are reported and variants have been discovered in several states and the Federal District. In this context, the study has as main objective to examine the influence of cl

10. Expression of a hantavirus N protein and its efficacy as antigen in immune assays
Hantavirus cardiopulmonary syndrome (HCPS) has been recognized as an important public heath problem. Five hantaviruses associated with HCPS are currently known in Brazil: Juquitiba, Araraquara, Laguna Negra-like, Castelo dos Sonhos, and Anajatuba viruses. The laboratory diagnosis of HCPS is routinely carried out by the detection of anti-hantavirus IgM and/or

11. Hantaviruses as emergent zoonoses
Hantaviruses belong to the Bunyaviridae family, which consists of vector-borne viruses. These viruses can provoke two infection types: hemorrhagic fever with renal syndrome (HFRS) - which occurs in the Old World - and hantavirus cardiopulmonary syndrome (HCPS) - an emergent zoonosis that can be found in many countries of the western hemisphere. Rodents are h

12. Predation of small mammals by the barn owl (Tyto alba) and its role in the control of hantavirus natural reservoirs in a periurban area in the municipality of Uberlândia, Minas Gerais, Brazil / Predação de pequenos mamíferos por suindara (Tyto alba) e seu papel no controle de reservatórios naturais de hantavírus em uma área periurbana do município de Uberlândia, Minas Gerais, Brasil
Small mammals, especially rodents, are the main prey of the barn owl and its diet is considered an accurated reflex of the local fauna composition and populational flutuations. The principal objectives of this study were to inventory the species of small mammals in the outskirts of the Municipality of Uberlândia, MG, based on the analysis of regurgitated pe
