Evaluation of three recombinant proteins for the development of ELISA and immun...
Santos, Anna Raquel Ribeiro dos; Serufo, Ângela Vieira; Figueiredo, Maria Marta; Godoi, Lara Carvalho; Vitório, Jéssica Gardone; Marcelino, Andreza PainBACKGROUND Visceral Leishmaniasis (VL) is an infectious disease that is a significant cause of death among infants aged under 1 year and the elderly in Brazil. Serodiagnosis is a mainstay of VL elimination programs; however, it has significant limitations due to low accuracy. OBJECTIVE This study aimed to evaluate three recombinant Leishmania infantum proteins (rFc, rC9, and rA2) selected from previous proteomi...
Immunogenomic screening approach to identify new antigens for the serological d...
Elisei, Rutyanne Maria Tonelli; Matos, Christiane Santos; Carvalho, Ana Maria Ravena Severino; Chaves, Ana Thereza; Medeiros, Fernanda Alvarenga CardosoSerological tests are preferentially used for the diagnosis of Chagas’ disease (CD) during the chronic phase because of the low parasitemia and high anti-Trypanosoma cruzi antibody titers. However, the current methods showed several disadvantages, as contradictory or inconclusive results, mainly related to the characteristics of the antigens used, in general, crude or whole parasites, but also due to antigen pr...
Sensitivity and specificity of parallel or serial serological testing for detec...
Arruda, Mauro Maciel de; Figueiredo, Fabiano Borges; Marcelino, Andreza Pain; Barbosa, José Ronaldo; Werneck, Guilherme Loureiro; Noronha, Elza FerreiraIn Brazil, human and canine visceral leishmaniasis (CVL) caused byLeishmania infantum has undergone urbanisation since 1980, constituting a public health problem, and serological tests are tools of choice for identifying infected dogs. Until recently, the Brazilian zoonoses control program recommended enzyme-linked immunosorbent assays (ELISA) and indirect immunofluorescence assays (IFA) as the screening and co...
