Yellow fever epizootics in non-human primates, São Paulo state, Brazil, 2008-2009
Moreno, Eduardo Stramandinoli; Spinola, Roberta; Tengan, Cilea Hatsumi; Brasil, Roosecelis Araujo; Siciliano, Melissa MascherattiDesde 2000, vem sendo observada a expansão da febre amarela (FA) no Sudeste do Brasil, sendo detectados casos em áreas consideradas silenciosas por décadas. Epizootias em primatas não humanos (NHPs) são considerados eventos sentinela para a detecção de casos humanos. É importante relatar eventos epizoóticos que podem ter impacto sobre o estado de conservação de espécies sensíveis. Descrevemos as epizootias, not...
First isolation of dengue 4 in the state of São Paulo, Brazil, 2011
Rocco, Iray Maria; Silveira, Vivian Regina; Maeda, Adriana Yurika; Silva, Sarai Joaquim dos Santos; Spenassatto, Carine; BISORDI, Ivani; Suzuki, AkemiWe report the first isolation of Dengue virus 4 (DENV-4) in the state of São Paulo, from two patients - one living in São José do Rio Preto and the other one in Paulo de Faria, both cities located in the Northwest region of the state. The virus isolations were accomplished in the clone C6/36 Aedes albopictus cell line, followed by indirect immunofluorescence assays, performed with type-specific monoclonal antib...
Isolation of yellow fever virus (YFV) from naturally infectied Haemagogus (Cono...
Souza, Renato Pereira de; Petrella, Selma; Coimbra, Terezinha Lisieux Moraes; Maeda, Adriana Yurika; Rocco, Iray Maria; Bisordi, IvaniAfter detecting the death of Howlers monkeys (genus Alouatta) and isolation of yellow fever virus (YFV) in Buri county, São Paulo, Brazil, an entomological research study in the field was started. A YFV strain was isolated from newborn Swiss mice and cultured cells of Aedes albopictus - C6/36, from a pool of six Haemagogus (Conopostegus) leucocelaenus (Hg. leucocelaenus) mosquitoes (Dyar & Shannon) collected at...
Evaluation of dengue NS1 antigen detection for diagnosis in public health labor...
Bisordi, Ivani; Rocco, Iray Maria; Suzuki, Akemi; Katz, Gizelda; Silveira, Vivian Regina; Maeda, Adriana Yurika; Souza, Renato Pereira deThe present work evaluated the diagnostic accuracy of detection of Dengue NS1 antigen employing two NS1 assays, an immunochromatographic assay and ELISA, in the diagnostic routine of Public Health laboratories. The results obtained with NS1 assay were compared with virus isolation and, in a subpopulation of cases, they were compared with the IgM-ELISA results obtained with convalescent samples. A total of 2,321...
