reference spectra for the organism and its close relatives (e.g., B. thailandensis). B. pseudomallei, although different from other Burkholderia spp. in its pathogenicity and epidemiology, is not easily discriminated from B. thailandensis or B. cepacia complex by using phenotypic tests (10). In summary, infection with B. pseudomallei should be considered in(More)
clinically recovered, and laboratory abnormalities returned to reference ranges at discharge 12 days after admission. The remaining 22 persons did not report any malaise and were examined 1 month after tick bite. They appeared healthy at that time, and PCR and ELISA gave negative results, arguing against possible asymptomatic B. miyamotoi infection. We(More)
Two hundred eight of 648 (32%) diarrheal stool samples collected from hospitalized children under 5 years of age during a 3-year period (1999, 2000, and 2002) in the city of Salvador, in the state of Bahia, Brazil, were rotavirus positive. One hundred sixty-four of 208 (78.8%) rotavirus-positive samples had genotype G9 specificity, predominantly in(More)
Zika virus (ZIKV) infection has been associated with severe complications both in the developing and adult nervous system. To investigate the deleterious effects of ZIKV infection, we used human neural progenitor cells (NPC), derived from induced pluripotent stem cells (iPSC). We found that NPC are highly susceptible to ZIKV and the infection results in(More)
Many protocols are available to produce monoclonal antibodies (MAbs) against bovine rotavirus (BRV) using purified virus particles but those methods are time-consuming and produce substantial loss of virus structure or infectivity. Polyethylene gycol (PEG) viral precipitation was investigated as a possible alternative method to obtain purified virus and(More)
The molecular epidemiology of a recent norovirus (NoV) outbreak in Brazil performed by comparative analysis with Genebank NoV sequences showed that the GII.4 strain was responsible for 72.5% of all NoV-positive cases (58/80). Other detected NoV strains included GII.3 (7/80; 8.8%) and GII.9 (8/80; 10%). This is the first outbreak reported in Bahia state,(More)
Dengue virus, commonly transmitted by mosquitoes, causes a human disease of significant social impact and presents a serious public health problem in Brazil. This report describes the unusual emergence of DENV-4 in northern Brazil after a nearly 30-year-long absence. DENV-4 genotype I is of Asian origin and was identified in the serum of patients receiving(More)
Z a mosquito-borne flavivirus discovered in Uganda in 1947, remained obscure until its emergence in Micronesia in 2007. Six years later, it arrived in French Polynesia and other islands in the South Pacific (1). The virus was first detected in Brazil in early 2015 and has now spread throughout South and Central America and the Caribbean (2). Infection often(More)
A bioeconomic model was developed to calculate economic values for biological traits in full-cycle production systems and propose selection indices based on selection criteria used in the Brazilian Aberdeen Angus genetic breeding programme (PROMEBO). To assess the impact of changes in the performance of the traits on the profit of the production system, the(More)
Rotavirus is a major cause of infectious diarrhea in infants and young children. The objective of this study was to characterize the genotypes of Human Rotavirus found in children hospitalized with acute diarrhea in the Pediatric Hospital Prof. Hosannah de Oliveira of the UFBA in Salvador, Bahia, Brazil, during the years of 1999, 2000 and 2002.
