2. Fitossanidade e qualidade de mudas de Eucalyptus urophylla x Eucalyptus grandis em função da aplicação de fosfito e silício
RESUMO O setor florestal é um dos que mais contribui em termos sociais, econômicos e ambientais para o Brasil. Dentro deste setor, a eucaliptocultura pode ser apontada como a mais importante do segmento, com o plantio que representa 5,56 milhões de hectares. A primeira etapa do processo de implantação de florestas de eucaliptos é a produção de mudas,

3. Gas exchange, root hydraulic conductivity, water use efficiency and the growth of Toona ciliata clones and seedlings
Resumo As plantações florestais estabelecidas com mudas apresentam heterogeneidade e dificuldades de manejo. Assim, uma alternativa a estes obstáculos é o uso de clones com alta produtividade. Além disso, as plantas clonais diferem das plantas seminíferas na estrutura do sistema radicular, o que pode influenciar a eficiência na absorção de água e d

4. Etiologia da mortalidade de miniestacas de Eucalyptus benthamii e possíveis fontes de inóculo
RESUMO Eucalyptus benthamii é originário da Austrália, cultivado na região Sul do Brasil, devido à sua tolerância ao clima frio. Durante a produção de mudas dessa espécie vários fatores bióticos e abióticos adversos têm surgido em viveiros. Dessa forma, o presente trabalho teve como objetivo avaliar a podridão de miniestacas de E. benthamii em

5. Community-acquired methicillin-resistant Staphylococcus aureus carrying SCCmec type IV and V isolated from healthy children attending public daycares in northeastern Brazil
Abstract Nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) have increasingly been reported in healthy communities. This study aimed to assess the rate of S. aureus in general and MRSA in particular from nasal secretion of children in daycare centers in Vitória da Conquista, Brazil. The isolates were identified based on morphology, b

6. Complete substitution of the Brazilian endemic clone by other methicillin-resistant Staphylococcus aureus lineages in two public hospitals in Rio de Janeiro, Brazil
Abstract Staphylococcus aureus is an important cause of bloodstream infections. Therefore, the main purpose of this work was to characterize a collection of 139 S. aureus isolates from bloodstream infections in two public hospitals in relation to their antimicrobial susceptibility profile, staphylococcal cassette chromosome mec types, and clonal relationship

7. Secondary myeloid neoplasms: bone marrow cytogenetic and histological features may be relevant to prognosis
Abstract Background: Secondary myeloid neoplasms comprise a group of diseases arising after chemotherapy, radiation, immunosuppressive therapy or from aplastic anemia. Few studies have addressed prognostic factors in these neoplasms. Method: Forty-two patients diagnosed from 1987 to 2008 with secondary myeloid neoplasms were retrospectively evaluated conce

8. Invasive Haemophilus influenzae disease in the vaccine era in Rio de Janeiro, Brazil
BACKGROUND Haemophilus influenzae (Hi) serotype b (Hib) conjugate vaccine was incorporated into the infant immunisation schedule in Brazil in 1999, where Hib was one of the major etiologic sources of community-acquired bacterial meningitis. OBJECTIVES The purpose of this study is to describe the molecular epidemiology of invasive Hi disease in Rio de Jane

9. Software Selegen-REML/BLUP: a useful tool for plant breeding
Abstract The software Selegen-REML/BLUP uses mixed models, and was developed to optimize the routine of plant breeding programs. It addresses the following plants categories: allogamous, automagous, of mixed mating system, and of clonal propagation. It considers several experimental designs, mating designs, genotype x environment interaction, experiments rep

10. ISOLATION AND GENOTYPING OF Toxoplasma gondii IN SERONEGATIVE URBAN RATS AND PRESENCE OF ANTIBODIES IN COMMUNICATING DOGS IN BRAZIL
The role of rodents in the epidemiology of toxoplasmosis was investigated in Londrina, Paraná State, Brazil. One hundred and eighty-one Rattus rattus and one Mus musculus were caught in 37 places. Blood and tissues were collected and submitted to the indirect fluorescence antibody test (IFAT) and the bioassay. Serum samples from 61 contacting dogs were also

11. Antimicrobial resistance and genetic diversity of Escherichia coli isolated from humans and foods
Antibiotic resistance has increased in recent years, raising the concern of public health authorities. We conducted a study of Escherichia coli isolates obtained from human and food samples to assess the prevalence of antimicrobial resistance and to determine the genotype and clonal relationship of 84 E. coli isolates (48 from humans and 36 from foods). An a

12. Clonal profile, virulence and resistance of Staphylococcus aureus isolated from sheep milk
The objective of this study was to characterize the clonal profile, virulence factors and antimicrobial resistance, particularly oxacillin resistance, of Staphylococcus aureus isolated from sheep milk. Milk samples were collected from all teats for the California Mastitis Test (CMT), somatic cell count, identification of S. aureus, investigation in these str
