Enfermedad granulomatosa crónica: infecciones múltiples como forma de presentación. Caso clínico pediátrico

Arch. argent. pediatr; 116 (6), 2018
La enfermedad granulomatosa crónica es una inmunodeficiencia primaria infrecuente, debida a un defecto en la actividad microbicida de los fagocitos, originada por mutaciones en los genes que codifican alguna de las subunidades del complejo enzimático nicotinamida adenina dinucleótido fosfato oxidasa. ...

Síndrome celulitis-adenitis, una forma infrecuente de presentación de la sepsis neonatal tardía: A propósito de dos casos

Arch. argent. pediatr; 116 (6), 2018
La sepsis es la principal causa de mortalidad neonatal. La forma precoz, habitualmente, está relacionada con la colonización recto-vaginal u otros factores de riesgo materno. En la forma tardía, es difícil establecer su origen; por lo general, es nosocomial o de la comunidad. El Streptococcus agalact...

La espondilodiscitis infecciosa es una infección poco frecuente en niños, con mayor incidencia en menores de 6 años. Se presenta el caso de una paciente de 8 años, que se internó por dolor lumbar de 2 meses de evolución, afebril. La radiografía, tomografía e imagen por resonancia magnética nucle...

Changes induced by co-inoculation in nitrogen-carbon metabolism in cowpea under salinity stress

Braz. j. microbiol; 49 (4), 2018
ABSTRACT To mitigate the deleterious effects of abiotic stress, the use of plant growth-promoting bacteria along with diazotrophic bacteria has been increasing. The objectives of this study were to investigate the key enzymes related to nitrogen and carbon metabolism in the biological nitrogen fixation p...

Antifungal activity of nanoemulsions encapsulating oregano (Origanum vulgare) essential oil: in vitro study and application in Minas Padrão cheese

Braz. j. microbiol; 49 (4), 2018
ABSTRACT The objective of this study was to evaluate the antifungal activity of nanoemulsions encapsulating essential oil of oregano (Origanum vulgare), both in vitro and after application on Minas Padrão cheese. Nanodispersions were obtained by the phase inversion temperature method. Cladosporium sp., ...

The potential of compounds isolated from Xylaria spp. as antifungal agents against anthracnose

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Anthracnose is a crop disease usually caused by fungi in the genus Colletotrichum or Gloeosporium. These are considered one of the main pathogens, causing significant economic losses, such as in peppers and guarana. The current forms of control include the use of resistant cultivars, sanitary pr...

Performance of rapid tests for carbapenemase detection among Brazilian Enterobacteriaceae isolates

Braz. j. microbiol; 49 (4), 2018
ABSTRACT The global emergence of carbapenemases led to the need of developing new methods for their rapid detection. The aim of this study was to evaluate the performance of the rapid tests for carbapenemase-producing and non-producing Enterobacteriaceae. Carbapenem non-susceptible Enterobacteriaceae fro...

Saccharomyces cerevisiae populations and other yeasts associated with indigenous beers (chicha) of Ecuador

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Chicha, a type of beer made mainly with maize or cassava, is a traditional fermented beverage of the Andean region. There have only been a few studies on yeasts associated with chicha fermentation, and the species diversity occurring during the production of this beverage is not known. The objec...

Identification of pathogenic and nonpathogenic Leptospira species of Brazilian isolates by Matrix Assisted Laser Desorption/Ionization and Time Flight mass spectrometry

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Matrix Assisted Laser Desorption/Ionization and Time of Flight mass spectrometry (MALDI-TOF MS) is a powerful tool for the identification of bacteria through the detection and analysis of their proteins or fragments derived from ribosomes. Slight sequence variations in conserved ribosomal protei...
