13. Analyses of the 16S-23S intergenic region of the phytoplasma causing the sugarcane white leaf disease in Yunnan Province, China
Sugarcane white leaf (SCWL) is an important disease caused by a phytoplasma. In Baoshan, Yunnan, China, SCWL was firstly observed in 2012, and has extended its area of occurrence to 600 hm² . Up to 52% of the plants may become diseased in a field and even complete loss of cane yield may result in the heavily infected fields, posing a serious threat to Yunna

14. Isolation of Microsporum gypseum in soil samples from different geographical regions of Brazil, evaluation of the extracellular proteolytic enzymes activities (keratinase and elastase) and molecular sequencing of selected strains
A survey of Microsporum gypseum was conducted in soil samples in different geographical regions of Brazil. The isolation of dermatophyte from soil samples was performed by hair baiting technique and the species were identified by morphology studies. We analyzed 692 soil samples and the recuperating rate was 19.2%. The activities of keratinase and elastase we

15. Caracterización y variabilidad genética de Colletotrichum gloeosporioides sensu lato en plantaciones de palma aceitera (Elaeis guineensis Jacq.) en Venezuela
Characterization was performed on the causal agent of anthracnose affecting leaves, rachis and fruits of oil palms in the southern region of Maracaibo Lake (Venezuela). Morphological tests included colony growth rate, diameter, color and type of mycelium, as well as the shape and size of conidia. Molecular characterization included specific PCR tests, ITS rD

16. 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. Isolamento, enumeração, identificação molecular e avaliação de propriedades probióticas de bactérias ácido-lácticas isoladas de leite de ovelha
Sheep milk, obtained from one of the oldest domestic animals, is unique for its high solids ratio. Its cheese are more famous than the milk itself. Lactic acid bacteria, abundant in milk from several mammals, include most of the probiotic microorganisms, which bring benefits to their consumers when ingested in viable and adequate portions. Few data are avail

19. Identification and biological activity of potential probiotic bacterium isolated from the stomach mucus of breast-fed lamb
The lactic acid bacterium E isolated from the stomach mucus of breast-fed lamb was identified by sequencing of 16S rDNA fragment and species-specific PCR as Lactobacillus reuteri. Its potential antimicrobial activity and ability to modulate immune system in vitro and in vivo was determined. The growth inhibition of potential pathogens decreased from Staphylo

20. ITS-rDNA phylogeny of Colletotrichum spp. causal agent of apple glomerella leaf spot.
Several diseases have affected apple production, among them there is Glomerella leaf spot (GLS) caused by Colletotrichum spp. The first report of this disease in apple was in plants nearby citrus orchards in São Paulo State, Brazil. The origin of this disease is still not clear, and studies based on the molecular phylogeny could relate the organisms evoluti

21. Diversidade e biogeografia de fungos no solo sob a projeção da copa de espécies arbóreas da Mata Atlântica / Diversity and biogeography of fungi in soil under the canopy of tree species in the Atlantic Forest
The community structure and diversity of fungi in soil under the canopy of four tree species (Ocotea dispersa, Ocotea teleiandra, Tabebuia serratifolia, and Mollinedia schottiana), in the Carlos Botelho State Park (PECB) were examined in two different seasons, using PCR-DGGE and rDNA ITS region clone library sequencing. The relationships between fungal commu

23. Fungos endofíticos associados à Vellozia compacta Mart. ex Schult. F. (Velloziaceae) presente em afloramentos rochosos nos estados de Minas Gerais e Tocantins
The Vellozia compact Mart. ex Schult. &Schult. F. (Velloziaceae), popularly known as canela-de-ema, is a tropical monocot, endemic, common in quartzite formations and adapted to multiple biotic and abiotic stresses. Endophytic fungi are microorganisms that live inside the vegetal tissues, in spaces inter or intracellular, without causing any apparent damage

24. Comparação genotípica e fenotípica de diferentes isolados clínicos de colonização e candidemia por Candida rugosa / Genotypic and phenotypic comparisons among different clinical isolates of colonization and candidemia by Candida rugosa
Introduction: Candida rugosa is an emergent pathogen recognized by its higher occurrence in Latin American countries. This yeast has the ability to colonize and cause human bloodstream infections as well as to show resistance to several antifungal drugs, specifically to azoles. Objectives: To compare phenotypic properties such as virulence attributes and ant
