1. Molecular characterization of Bacillus thuringiensis strains to control Spodoptera eridania (Cramer) (Lepidoptera: Noctuidae) population
Abstract The main objective of this study was to characterize the toxicity and genetic divergence of 18 Bacillus thuringiensis strains in the biological control of Spodoptera eridania. Bacterial suspensions were added to the S. eridania diet. Half of the selected B. thuringiensis strains caused high mortality seven days after infection. The genetic divergenc

2. Identification of circo-like virus-Brazil genomic sequences in raw sewage from the metropolitan area of São Paulo: evidence of circulation two and three years after the first detection
BACKGROUND Two novel viruses named circo-like virus-Brazil (CLV-BR) hs1 and hs2 were previously discovered in a Brazilian human fecal sample through metagenomics. CLV-BR hs1 and hs2 possess a small circular DNA genome encoding a replication initiator protein (Rep), and the two genomes exhibit 92% nucleotide identity with each other. Phylogenetic analysis b

3. Endophytic bacterial diversity in banana 'Prata Anã' (Musa spp.) roots
The genetic diversity of endophytic bacteria in banana 'Prata Anã' roots was characterized. Two hundred and one endophytic bacteria were isolated, 151 of which were classified as Gram-positive and 50 as Gram-negative. No hypersensitivity response was observed in any of the isolates. The rep-PCR technique generated different molecular profiles for each prime

4. Variation in extragenic repetitive DNA sequences in Pseudomonas syringae and potential use of modified REP primers in the identification of closely related isolates
In this study, Pseudomonas syringe pathovars isolated from olive, tomato and bean were identified by species-specific PCR and their genetic diversity was assessed by repetitive extragenic palindromic (REP)-PCR. Reverse universal primers for REP-PCR were designed by using the bases of A, T, G or C at the positions of 1, 4 and 11 to identify additional polymor

5. Genetic diversity and virulence pattern in field populations of Pyricularia grisea from rice cultivar Metica-1.
Rice blast is a major yield constraint of the irrigated rice in the State of Tocantins, Brazil. The objective of this investigation was to study the phenotypic and genetic diversity within the pathogen population of Pyricularia grisea in samples collected from four individual farms of rice cultivar Metica-1, under epidemic conditions of leaf blast. A set of

6. Taxonomia de pracriontes isolados de cnidários de São Sebastião, SP, Brasil / Taxonomy of prokaryontes isolated from cnidarians of São Sebastião, SP, Brasil
Microorganisms have a key role in the health of cnidarians establishing ecologic relationships, of parasitism to mutualism. The knowledge on the diversity of prokaryotes associated with corals in Brazil is very limited. This is the first study on the taxonomic characterization of heterotrophic bacteria, including putative N2-fixing and specially vibrios isol

7. Aquisição e resistência a mudança dos operantes variar e repetir
The aim of the present study was to investigate the effects of extinction and independent reinforcers upon the acquisition and resistance to change of variation and repetition in humans. College students were required to emit sequences of responses to produce reinforcers according to the criterion of the phase in effect (presented in an ABA or a BAB design).

9. Características fenotípicas atípicas de isolados de Klebsiella pneumoniae de um surto na unidade de terapia intensiva neonatal, no Brasil
Isolados de Klebsiella sp. produtora de beta-lactamase de espectro estendido (ESBL), responsável por um surto na Unidade Neonatal de Terapia Intensiva (UNTI) do Hospital Universitário de Londrina, Paraná, Brasil apresentaram características fenotípicas atípicas que dificultaram sua identificação e a diferenciação entre as espécies Klebsiella pneum

10. Análise transcricional do operon pst de Escherichia coli. / Transcriptional analisys of pst operon Escherichia coli.
O operon pst de Escherichia coli é formado pelos genes pstS, pstC, pstA, pstB e phoU. Os quatro primeiros genes codificam proteínas que compõem um sistema de transporte do tipo ABC denominado Pst. O sistema Pst, junto com a proteína PhoU participa da repressão dos genes do regulon PHO. A transcrição dos genes do operon pst é induzida pela carência d

11. Caracterização da diversidade de estirpes de Bradyrhibium japonicum e B. elkanii estabelecidas por inoculação em solos do Cerrados, isoladas de nódulos de soja
The plasticity of rhizobial genomes is far greater than previously thought, with complex genomic recombination events that may be accelerated by the often-stressful environmental conditions of the tropics. This study aimed at evaluating changes in soybean rhizobia due to adaptation to inhospitable environmental conditions (high temperatures, drought and acid

12. Structural and comparative analysis of the genome of leifsonia xyli subsp. xyli. / Análise estrutural e comparativa do genoma de Leifsonia xyli subsp. xyli.
Leifsonia xyli subsp. xyli (Davis et al.; 1984; Evtushenko et al.; 2000) is the causal agent of one of the most economically important disease of sugarcane worldwide, i.e, ratoon stunting disease (Gillaspie Jr. &Davis, 1992; Davis et al.; 1994). The main objective of this study was to confirm the assembly of the genome of L. xyli subsp. xyli obtained after s
