13. Assessing the diversity of the virulence potential ofEscherichia coli isolated from bacteremia in São Paulo, Brazil
Most of the knowledge of the virulence determinants of extraintestinal pathogenicEscherichia coli (ExPEC) comes from studies with human strains causing urinary tract infections and neonatal meningitis and animal strains causing avian colibacillosis. In this research, we analyzed the phylogenetic background, the presence of 20 ExPEC virulence factors, and the

14. Pyricularia blast on white oats: a new threat to wheat cultivation
A newly emerged disease, the Pyricularia blast caused by Pyricularia grisea, is commonly observed on wheat and black oats, since its discovery in 1985. Within a few years the disease spread to other species of Gramineae, but white oat cultivars remained resistant and were the only ones among cultivated cereals resistant to this disease. In 2012, one commerci

15. Diversidade genética de isolados do fungo Sporisorium scitamineum analisada através de fingerprinting da região telomérica / Genetic diversity of isolates of the fungus Sporisorium scitamineum analyzed by fingerprinting the telomeric region
The genetic diversity of Sporisorium scitamineum, the sugarcane smut agent, was characterized in a 14 isolates collection. The isolates were obtained from various sugarcane growing areas and RFLP of the telomeric region was used as molecular marker, compared with AFLP. Teliospores were collected from the whip of infected plants. Teliospores are diploids and

16. Influência da variabilidade genética sobre biomarcadores de dano oxidativo e não oxidativo em pacientes com doença pulmonar obstrutiva crônica (DPOC)
Chronic Obstructive Pulmonary Disease (COPD) is a slowly progressive condition of poor reversibility that is characterized by airflow limitation associated with an abnormal inflammatory response of the lungs. Its development and progression are related to increased oxidative stress, which is an important pathogenic component of airway inflammation in this di

17. Comparação genotípica e fenotípica de diferentes isolados clínicos e ambientais de Rhodotorula spp. / Genotypic and phenotypic comparisons among clinical and environmental isolates of Rhodotorula spp.
Introduction: Rhodotorula spp. are yeasts widely distributed in the environment and can colonize the human body at different anatomical locations. This emerging pathogen is capable of causing superficial and invasive infections in humans whereas bloodstream infection is the most commonly described in the literature. Mainly three species have been related to

18. Isoenzymatic characterization of Colletotrichum kahawae isolates with different levels of aggressiveness
The hemibiotrophic fungus Colletotrichum kahawae is the causal agent of Coffee Berry Disease - CBD, an economically devastating disease restricted to Arabica coffee production in Africa. Understanding pathogen variability is crucial for the implementation of disease control measures. In this study, six isoenzymatic systems (esterase, acid and alkaline phosph

23. Variabilidade patogênica de Colletotrichum gloeosporioides oriundo de populações nativas de Stylosanthes spp. de três estados brasileiros.
RESUMO: Folhas e caules, com sintomas de antracnose, foram coletados de populações nativas de Stylosanthes spp., de 1997 a 2000, em localidades de Minas Gerais, Goiás e Bahia, para avaliar a variabilidade patogenica do agente causal (Colletotrichum gloeosporioides). Duzentos e setenta quatro isolados monosporicos foram classificados em 20 grupos, usando-s

24. Influência do parasito e do hospedeiro no potencial patogênico de populações de Trypanosoma cruzi I na fase aguda da infecção experimental em camundongos
The populations of Trypanosoma cruzi (Tc) show high biological and genetic variability and are classified into six groups TcI - TcVI. Currently, data concerning the pathogenicity of the TcI are conflicting and may be due to host genetic component and spread to humans in populations of T. cruzi restricted to a wild environment. However, the insertion of new v
