ABSTRACT
HELLP syndrome (hemolysis, elevated liver enzymes and low platelets) represents a severe form ofpreeclampsia associated with serious maternal and fetal morbiditiesand even death. Usually HELLP syndrome appears during the evolution of a severepreeclampsia; however HELLP syndrome can have atypical clinical manifestations.We report a 22-year-old female who consulted at 20 weeks of pregnancy for lumbarpain, dysuria and fever. A urinalysis revealed the presence of white blood cells. Thepatient was admitted to hospital and treated with antimicrobials. Forty eight hoursafter admission a proteinuria of 440 mg/24 h was detected. A severe pre eclampsia-HELLP syndrome was diagnosed. However the patient remained with normal bloodpressure. An elevation of liver enzymes and creatinine were observed. Five dayslater fetal death was confirmed and an abortion was induced. The patient requireda platelet transfusion. Four days after the abortion, the patient was discharged ingood conditions.

Se evaluó el efecto de las épocas climáticas (lluvia y sequía) y del estrato de la muestra (suelo rizosférico, raíces y hojas) sobre la población de los géneros Azotobacter, Beijerinckia, Derxia, Azospirillum, Herbaspirillum, Gluconacetobacter y Burkholderia en el Eucalipto (Eucalyptus sp.). Así mismo, se evalúo su capacidad en la producción de compuestos indólicos como promotores del crecimiento vegetal y su actividad de reducción de acetileno como indicador de la fijación biológica de nitrógeno. Los resultados no registraron diferencias estadísticas significativas en el test de Tukey (P ≤ 0.05) en la población con respecto a la época climática. Con respecto al estrato de muestra, los aislamientos tentativos de Herbaspirillum sp. y Azospirillum sp. presentaron diferencias significativas en suelo rizosférico y raíces. Se obtuvieron 44 aislamientos de los cuales se agruparon por caracterización fenotípica como: 14 presuntivos de Beijerinckia sp., 12 de Azotobacter sp., ocho de Derxia sp., cuatro de Herbarpirillum sp., cinco de Azospirillum sp., uno de Gluconacetobacter sp. y uno de Burkholderia sp. Por su alto potencial fueron seleccionados y criopreservados los aislamientos C27, C26 y C25, las cuales presentaron los mejores valores de eficiencia in vitro, superando valores de producción de las cepas de referencia utilizadas (A. chroococcum (AC1) y A. brasilense (SP7)).
The effect of climatic seasons (rainy and dry) and the stratum sample (rhizospheric soil, roots and leaves) the population of the genera Azotobacter, Beijerinckia, Derxia, Azospirillum, Herbaspirillum, Gluconacetobacter and Burkholderia in soil rhizosphere, roots and leaves of Eucalyptus (Eucalyptus sp.). It also assesses their ability to produce indoles compounds as plant growth promoters and their acetylene reduction activity as an indicator of biological fixation of nitrogen. The results showed no statistically significant differences in the Duncan test (P ≤ 0.05) in the population with respect to the climate epoch, suggesting that these bacteria are able to tolerate stress conditions by different physiological mechanisms. With respect to the stratum sample isolates attempts of Herbaspirillum sp. and Azospirillum sp. significant differences in rhizospheric soil and roots. We obtained 44 isolates of which were grouped by phenotypic characterization as 14 suspected of Beijerinckia sp., 12 Azotobacter sp., 8 Derxia sp., 4 Herbaspirillum sp., 5 Azospirillum sp., 1 Gluconacetobacter sp. and 1 Burkholderia sp. Due to their high potential were selected isolates C27, C26 and C25. These four strains present the best values of efficiency in vitro, exceeding production values of the reference strains used (A. chroococcum (AC1) and A. brasilense (SP7)).
