Dengue: 30 years of cases in an endemic area
Monteiro, Daniela Cristina Sensato; Souza, Natália Nata´lia; Amaral, Jane Cavalcante; Lima, Kaynan Bezerra de; Araújo, Fernanda Montenegro Carvalho deThe present study aimed to review literature on studies of dengue cases conducted over 30 years in the state of Ceara´. Between November 2015 and January 2016, articles published in Portuguese and English in 7 databases were searched using keywords and a Boolean operator. A total of 191 articles were identified in the databases; 133 were excluded according to the exclusion criteria, and 58 were included in the ...
Cross-sectional study to determine the prevalence of hepatitis B and C virus in...
Barbosa, Jakeline Ribeiro; Bezerra, Cristianne Sousa; Carvalho-Costa, Filipe Anibal; Azevedo, Carolina Pimentel de; Flores, Geane LopesBackground: HBV (Hepatitis B Virus) and HCV (Hepatitis C Virus) infections are more prevalent in vulnerable populations than the general population. The objective of this study was to investigate the prevalence of HBV and HCV infection in HIV-positive patients (GI), chronic renal failure (CRF) patients (GII) and coagulation disorder individuals (GIII). Methods: A cross-sectional study was conducted from June 20...
A DNA vaccine candidate expressing dengue-3 virus prM and E proteins elicits ne...
Paula, Sérgio Oliveira De; Lima, Danielle Malta; França, Rafael Freitas de Oliveira; Gomes-Ruiz, Alessandra Cristina; Fonseca, Benedito Antônio Lopes daIn an effort to develop a suitable DNA vaccine candidate for dengue, using dengue-3 virus (DENV-3) as a prototype, the genes coding for premembrane (prM) and envelope proteins (E) were inserted into an expression plasmid. After selecting recombinant clones containing prM/E genes, protein expression in the cell monolayer was detected by indirect immunofluorescence and immunoprecipitation assays. After selecting ...
Recognition of leptospirosis in dengue-suspected cases during dengue outbreak i...
Oliveira, Augusto César Aragão; Fontes, Raissa Matos; Praciano, Claudênia Costa; Araújo, Fernanda Montenegro de CarvalhoDengue fever frequently presents with non specific sy mptoms, making it difficult to be distinguished from other acute febrile illnesses, including leptospi rosis. Given this, serum samples from 82 patients with clinical features of dengue-like illness were ev aluated for dengue infection by IgM-enzyme-linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). Negative samp...
Detection of parvovirus B19 infection in formalin-fixed and paraffin-embedded p...
Quemelo, Paulo Roberto Veiga; Lima, Danielle Malta; Fonseca, Benedito Antônio Lopes da; Peres, Luiz CesarParvovirus B19 infection was first discovered in 1975 and it is implicated in fetal death from hydrops fetalis the world over. Diagnosis is usually made through histological identification of the intranuclear inclusion in placenta and fetal organs. However, these cells may be scarce or uncharacteristic, making definitive diagnosis difficult. We analyzed histologically placentas and fetal organs from 34 cases of...
