1. New insights into the detection and molecular characterization of Cryptosporidium with emphasis in Brazilian studies: a review
ABSTRACT Cryptosporidium spp. is a pathogenic protozoan present in the gastrointestinal tract of several hosts. This protozoan was originally classified as within the Coccidia Class and has recently been reclassified to gregarine based on studies that observed the evolutionary phases from the process of excision and sequencing of the 18S rRNA gene. Molecular

2. Effect of rosette size, clonality and spatial distribution on the reproduction of Vriesea carinata (Bromeliaceae) in the Atlantic Forest of Paraná, southern Brazil
ABSTRACT Plant size and clonality are important traits for explaining the reproductive effort of clonal plants. Larger plants can invest more resources into reproduction, and clonality is known to increase reproductive effort. Moreover, reproductive effort is influenced by environmental variation, and so the spatial distribution of plants may affect plant re

3. Drug resistance profiles and clonality of sporadic Shigella sonnei isolates in Ankara, Turkey
The aims of this study were to investigate drug resistance rates, types of extended spectrum beta lactamases (ESBLs), and molecular epidemiological characteristics of 43 Shigella sonnei isolates. Ampicillin-sulbactam, amoxicillin-clavulanate, chloramphenicol, and ciprofloxacin were the most active antibiotics. Five isolates harbored blaSHV-12, blaTEM-1 and b

4. Application of RAPD-PCR for Determining the Clonality of Methicillin Resistant Staphylococcus aureus Isolated from Different Hospitals
Randomly amplified polymorphic DNA (RAPD)-PCR was applied with ten random 10-mer primers to examine the molecular diversity among methicillin resistant Staphylococcus aureus (MRSA) strains in the hospitals and to investigate the epidemiological spread of these strains between different hospitals. The main objective of the study was to identify appropriate pr

5. Gene rearrangement study for minimal residual disease monitoring in children with acute lymphocytic leukemia
OBJECTIVE To detect markers for minimal residual disease monitoring based on conventional polymerase chain reaction for immunoglobulin, T-cell receptor rearrangements and the Sil-Tal1 deletion in patients with acute lymphocytic leukemia. METHODS Fifty-nine children with acute lymphocytic leukemia from three institutions in Minas Gerais, Brazil, were pros

6. Relações clonais, genes de virulência e patogenicidade dos Streptococcus agalactiae isolados de peixes / Clonality, virulence genes and pathogenicity of Streptococcus agalactiae strains isolated from fish
O S. agalactiae representa o principal problema de saúde no cultivo de tilápia, responsável por prejuízos em todo o mundo. A diversidade do S. agalactiae isolado de peixes, assim como seus fatores de virulência, ainda são pouco estudados. Tendo em vista esta considerações, este trabalho teve por objetivos estudar a diversidade genética dos S. agalac

7. Nosocomial and community infections due to class A extended-spectrum β-lactamase (ESBLA)-producing Escherichia coli and Klebsiella spp. in southern Brazil
OBJECTIVES: To determine the prevalence of class A extended spectrum β-lactamases (ESBL)-producing Escherichia coli and Klebsiella spp., and to investigate clonality among ESBL-producing isolates of nosocomial and community infections. METHODS: The study involved 354 nosocomial infections samples and 992 community infections samples, obtained between 2003 a

8. Polymerase chain reaction-Based clonality analysis of cutaneous B-cell lymphoproliferative processes
INTRODUCTION: The differential diagnosis of B-cell lymphoproliferative processes remains a challenge for pathologists, dermatologists and oncologists, despite advances in histology, immunohistochemistry and molecular biology. OBJECTIVE: Evaluate aid and limitations of clonality analysis in the diagnosis of primary cutaneous B-cell lymphomas and B-cell pseudo

9. Clonality analysis of giant cell lesions of the jaws
Apesar da importância que a clonalidade das lesões tem para o entendimento da patogênese e progressão dos tumores, ainda não foi feita essa investigação em lesões de células gigantes dos maxilares. O objetivo desse trabalho foi analisar a natureza clonal de lesões periféricas de células gigantes (LPCG) e de lesões centrais de células gigantes (

10. Clonal diversity and conservation genetics of the medicinal plant Carapichea ipecacuanha (Rubiaceae)
The roots of the understorey shrub Carapichea ipecacuanha (ipecac) have medicinal properties, and the uprooting of wild plants has supplied most of the world demand for this species. Although under severe population decline, C. ipecacuanha lacks legal protection. In the wild, the aerial stems of ipecac clump together to form clusters with well-defined border

11. Caracterização fenotípica e genotípica de amostras de enterococcus spp. isoladas em dois hospitais de Porto Alegre
As características fenotípicas e genotípicas de 203 isolados de Enterococcus spp. proveniente de diferentes amostras clínicas em dois hospitais localizados na cidade de Porto Alegre, Rio Grande do Sul, Brasil, foram estudadas. As espécies foram identificadas através de testes bioquímicos convencionais e pelo uso do sistema automatizado VITEK 2 (BioMé

12. Genetic relationship of diarrheagenic Escherichia coli pathotypes among the enteropathogenic Escherichia coli O serogroup
The genetic relationship among the Escherichia coli pathotypes was investigated. We used random amplified polymorphic DNA (RAPD) data for constructing a dendrogram of 73 strains of diarrheagenic E. coli. A phylogenetic tree encompassing 15 serotypes from different pathotypes was constructed using multilocus sequence typing data. Phylogram clusters were used
