2. Transmissão e patogenicidade de duas espécies de bipolaris associadas às sementes de panicum maximum Jacq.
Setenta e duas amostras de sementes de 24 genótipos de Panicum maximum Jacq., plantados na área experimental da Embrapa Cerrados, Planaltina, Distrito Federal, foram analisadas quanto à sanidade usando-se o teste de isolamento em meio de BDA + S. Os principais fungos fi topatogênicos isolados foram Bipolaris zeae Sivan. e Bipolaris maydis (Y. Nisik. & C.

3. Detection of cry1 genes in Bacillus thuringiensis isolates from South of Brazil and activity against Anticarsia gemmatalis (Lepidoptera: Noctuidae)
The bacterium Bacillus thuringiensis (Bt) is characterized by its ability to produce proteic crystalline inclusions during sporulation. Cry1 protein has insecticidal activity and is highly specific to certain insects and not toxic to unrelated insects, plants or vertebrates. In this work, the patogenicity of twelve Bt isolates was tested against Anticarsia g

4. Identificação de atividade metalo-oligopeptidásica Thimet-like em Paracoccidioides brasiliensis: um novo fator de patogenicidade fúngica? / Identification of a metalo-oligopeptidasic TOP-like activity in Paracoccidioides brasiliensis: a novel factor of fungal patogenicity?
Paracoccidioides brasiliensis (Pb), é uma micose sistêmica grave com formas aguda e crônica. As proteases ou peptidases são enzimas proteolíticas que ocorrem em todos os organismos e correspondem a 1-5% de seus conteúdos genéticos. Estas enzimas estão envolvidas em processos biológicos essenciais, como a coagulação sanguínea, morte celular e dife

5. Molecular typing and pathogenic potential characterization of Yersinia enterocolitica biotype 1A strains of diverse origins. / Tipagem molecular e caracterização do potencial patogênico de linhagens de Yersinia enterocolitica biotipo 1A de origens diversas
Among the 12 species of the genus Yersinia, Yersinia enterocolitica is the most prevalent cause of illness in humans and animals. Among other characteristics, its patogenicity is related to six biotypes: 1B and 2 to 5 considered pathogenic and the 1A biotype considered non-pathogenic. Despite being defined as non-pathogenic, literature has been shown that bi

6. Avaliação a campo de uma estirpe de Bacillus thuringiensis tóxica à lepidoptera e seu possível efeito adverso sobre espécies não-alvo
The using of the Bacillus thuringiensis on the cabbage culture for the control of the diamondback moth has been an alternative commonly used by the producers to substitute the traditional chemical insecticides that cause damages to the environment and to the human health, as opposed to the biological products that are harmless to the humans so as to the non-

7. Cryptococcus environmental species: molecular characterization, virulence and susceptibility to fluconazole before and after inoculation in a murine model. / Caracterização molecular, virulência e suscentibilidade ao fluconazol de espécies ambientais de Cryptococcus, antes e após inoculação em modelo murino
Species of Cryptococcus neoformans and C. gattii are the main ones in the genus causing infection in man while C. albidus and C. laurentii are less involved. This study evaluated the in vivo pathogenicity, factors and genes related to virulence and the susceptibility to fluconazole before and after inoculation in immunocompetent BALB/c mice of ten environmen

8. Epidemiological characterization of resistance and PCR typing of shigella flexneri and shigella sonnei strains isolated from bacillary dysentery cases in Southeast Brazil / Caracterização biologica e molecular de amostras de shigella flexneri e shigella sonnei isoladas da regiao de Campinas-SP
Shigella spp are gram-negative, anaerobic facultative, non-motile, and non-sporulated bacilli of the Enterobacteriaceae family, responsible for Shigellosis or the Bacillary Dysentery (BD) disease, an important cause of worldwide morbidity and mortality. The pathogenic determinants of Shigella spp include high molecular weight plasmids responsible for the bac

9. Effects of homeopathic medecine s and biotherapics on Trypanosoma evansi (STEEL, 1885) BALBIANI, 1988 and Trypanosoma cruzi experimentally infected mice CHAGAS, 1909 / Efeitos de Medicamentos Homeopáticos e Bioterápicos em Camundongos Experimentalmente Infectados por Trypanosoma evansi (STEEL, 1885) BALBIANI, 1988 e Trypanosoma cruzi CHAGAS, 1909
With the aim to study the therapeutic and prophylactic effects of homeopathic medicines were employed acute and chronic infection models: experimental infection of mice by Trypanosoma evansi and by Trypanosoma cruzi, respectively, as a mice immunization model with T. evansi extract aiming evaluate the homeopathic biotherapic immunomodulatory effects. It were

10. Case study spontaneous of canine and feline sporotrichosis, and evaluation of the melanin in cells of Sporothrix schenckii in model murine / Estudo de casos espontâneos de esporotricose canina e felina, e avaliação da melanina em células de Sporothrix schenckii em modelo murino
Sporotrichosis is a zoonotic mycosis, caused by dimorphic fungus Sporothrix schenckii, that attacks the man and several animal species, especially domestic felines. Among the factors of patogenicity of the fungus, stands out the melanin presence. This work had as objective: to study spontaneous cases of esporotricose in canine and felines, evaluating the asp

11. Isolamento, avaliação e caracterização de Bacillus thuringiensis, com potencial para controle de diptera e lepidoptera
Among the insects that harm the socioeconomic development of Serra Gaúcha, exist the dipterous, of the family Simuliidae that, due to its hematofagic process, cause discomfort and allergies to active rural tourists. In the agricultural regions, the lepidopterous, of the family Noctuidae, constitute curses of several cultures, constituting an economical prej

12. Caracterização de um novo fator de colonização (FC O25) de Escherichia coli isoladas de colibacilose neonatal bovina / Characterization of a new colonization (CF O25) of Escherichia coli isolated from neonatal bovine colibacillosis
Infections from Escherichia coli are frequent in domestic animals, affecting mainly newborn animals in the post weaning period, being thus responsible for important economic losses in the cattle, porcine and lamb herds. The establishment of the bacterium in the host is made by colonization and it is a process mediated by proteins called adhesins that are dis
