Fusarium and Aspergillus mycotoxins contaminating wheat silage for dairy cattle feeding in Uruguay

Braz. j. microbiol; 47 (4), 2016
Abstract Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining n...

Screening of freshwater fungi for decolorizing multiple synthetic dyes

Braz. j. microbiol; 47 (4), 2016
Abstract The biodegradation of synthetic dyes by fungi is emerging as an effective and promising approach. In the present study, freshwater fungal strains isolated from submerged woods were screened for the decolorization of 7 synthetic dyes. Subsequently, 13 isolates with high decolorization capability ...

The importance of integrons for development and propagation of resistance in Shigella: the case of Latin America

Braz. j. microbiol; 47 (4), 2016
Abstract In Latin America, the disease burden of shigellosis is found to coexist with the rapid and rampant spread of resistance to commonly used antibiotics. The molecular basis of antibiotic resistance lies within genetic elements such as plasmids, transposons, integrons, genomic islands, etc., which a...

The role of gyrA and parC mutations in fluoroquinolones-resistant Pseudomonas aeruginosa isolates from Iran

Braz. j. microbiol; 47 (4), 2016
Abstract The aim of this study was to examine mutations in the quinolone-resistance-determining region (QRDR) of gyrA and parC genes in Pseudomonas aeruginosa isolates. A total of 100 clinical P. aeruginosa isolates were collected from different university-affiliated hospitals in Tabriz, Iran. Minimum in...

Antimicrobial profile of Arthrobacter kerguelensis VL-RK_09 isolated from Mango orchards

Braz. j. microbiol; 47 (4), 2016
Abstract An actinobacterial strain VL-RK_09 having potential antimicrobial activities was isolated from a mango orchard in Krishna District, Andhra Pradesh (India) and was identified as Arthrobacter kerguelensis. The strain A. kerguelensis VL-RK_09 exhibited a broad spectrum of in vitro antimicrobial act...

Cytotoxicity and anti-Sporothrix brasiliensis activity of the Origanum majorana Linn. oil

Abstract The study aimed to evaluate the anti-Sporothrix sp. activity of the essential oil of Origanum majorana Linn. (marjoram), its chemical analysis, and its cytotoxic activity. A total of 18 fungal isolates of Sporothrix brasiliensis (n: 17) from humans, dogs and cats, and a standard strain of Sporot...

Analysis of risk factors and clinical manifestations associated with Clostridium difficile disease in Serbian hospitalized patients

Braz. j. microbiol; 47 (4), 2016
Abstract Clostridium difficile is the leading cause of infectious diarrhoea in hospitalized patients. The aim of this study was to determine the risk factors important for the development of hospital-acquired Clostridium difficile-associated disease and clinical manifestations of Clostridium difficile-as...

Rhizobacterial characterization for quality control of eucalyptus biogrowth promoter products

Braz. j. microbiol; 47 (4), 2016
Abstract Plant growth-promoting rhizobacteria strains from special formulations have been used to optimize eucalyptus cutting production. To undertake quality control for the formulated products, the rhizobacterial strains should be characterized to assess their purity and authentication. In the present ...
