Entre el terror y la solidaridad : La influencia de la revolución haitiana en las independencias de Venezuela y Nueva Granada (1804-1825)

En este trabajo me propongo analizar la influencia de la revolución de Haití en las independencias de Venezuela y Colombia durante los años 1804-1825. Miintención es demostrar que las repercusiones del proceso haitiano fueron vastas, complejas y sufrieron importantes cambios durante el transcurso de los años. En líneas generales, la revolución generó pánico entre las elites criollas y peninsulares y esperanzas entre grupos de esclavos y pardos. Inicialmente los sectores criollos revolucionarios buscaron evitar todo contacto con la isla y eludir el modelo insurgente haitiano por considerar que produciría en la Tierra Firme una "guerra de razas" y una hecatombe similar a la que, en su opinión, allí había acontecido. Sin embargo, a partir de 1812-1813 debido a las dificultades de la guerra de independencia una fracción de la elite criolla comenzó a estrechar vínculos con la República del Sur de Haití a través de contactos diplomáticos y corsarios. Estas primeras relaciones, más bien tímidas, fueron la condición de posibilidad de un cambio importante que sobrevino en 1816. En dicho año, debido a la reconquista de la expedición realista, la mayoría de los líderes independentistas huyeron de Tierra Firme y tuvieron que exiliarse en Haití, uno de los pocos lugares donde encontraron refugio y apoyo. En aquel contexto, se dio el pacto entre Alexandre Petión y Simón Bolívar, por el cual el primero se comprometió a aportar armas, barcos y hombres a la causa patriota a cambio de la emancipación de los esclavos hispanoamericanos. Este acuerdo fue fundamental ya que no sólo posibilitó la exitosa contraofensiva independentista, sino que además le dio un cariz social al proceso revolucionario de Venezuela y Colombia. Así, a partir de 1816 y hasta 1821, se dieron numerosos contactos e incluso el gobierno de Jean Pierre Boyer (sucesor de Alexandre Petión) colaboró con otras dos expediciones a cargo de Gregor Mac Gregor para liberar Panamá y Río Hacha. Sin embargo, el cambio no fue total y aún durante estos años, los líderes criollos continuaron teniendo reparos frente al peligro de la explosión de un nuevo Haití en la Tierra Firme hispana. Por último, el fin de la guerra de independencia abrió un nuevo contexto en el cual aquellos miedos se intensificaron debido a la movilización social interna. Esto derivó en nuevo alejamiento y el gobierno de Colombia no sólo se negó a mantener relaciones con Haití, sino que incluso lo excluyó del Congreso de Panamá.

Characterization of Streptococcus bovis from the rumen of the dromedary camel and Rusa deer

Aims: Isolation and characterization of Streptococcus bovis from the dromedary camel and Rusa deer. Methods and Results: Bacteria were isolated from the rumen contents of four camels and two deer fed lucerne hay by culturing on the semi-selective medium MRS agar. Based on Gram morphology and RFLP analysis seven isolates, MPR1, MPR2, MPR3, MPR4, MPR5, RD09 and RD11 were selected and putatively identified as Streptococcus. The identity of these isolates was later confirmed by comparative DNA sequence analysis of the 16S rRNA gene with the homologous sequence from S. bovis strains, JB1, C14b1, NCFB2476, SbR1, SbR7 and Sb5, from cattle and sheep, and the Streptococcus equinus strain NCD01037T. The percentage similarity amongst all strains was >99%, confirming the identification of the camel isolates as S. bovis. The strains were further characterized by their ability to utilize a range of carbohydrates, the production of volatile fatty acids (VFA) and lactate and the determination of the doubling time in basal medium 10 supplemented with glucose. All the isolates produced L-lactate as a major fermentation end product, while four of five camel isolates produced VFA. The range of carbohydrates utilized by all the strains tested, including those from cattle and sheep were identical, except that all camel isolates and the deer isolate RD11 were additionally able to utilize arabinose. Conclusions: Streptococcus bovis was successfully isolated from the rumen of camels and deer, and shown by molecular and biochemical characterization to be almost identical to S. bovis isolates from cattle and sheep. Significance and Impact of the Study: Streptococcus bovis is considered a key lactic acid producing bacterium from the gastrointestinal tract of ruminants, and has been implicated as a causative agent of lactic acidosis. This study is the first report of the isolation and characterization of S. bovis from the dromedary camel and Rusa deer, and suggests a major contributive role of this bacterium to fermentative acidosis.

Haematological values of young male rusa deer (Cervus timorensis)

Objective To measure haematological values of clinical significance for rusa deer and provide reference data for farmed animals. Design Blood samples were collected regularly from eight male rusa deer from 14 days to 27 months old. Procedure Blood samples, collected by venipuncture, were analysed within 6 hours of collection for red cell count, haemoglobin, packed cell volume, plasma glucose, white cell count and differentials. Results Haemoglobin concentrations appeared to increase with age and ranged from 6.0 to 20.9 g/dL. Packed cell volume and plasma glucose concentration did not appear to vary with age. White cell counts ranged from 6.3 to 7.0 x 10(9)/L and differential counts indicated neutrophils > lymphocytes > monocytes > eosinophils > basophils. In general, the values for packed cell volume, red cell count, mean cell volumes and mean cell haemoglobin concentrations were within ranges previously reported for captive or sedated rusa deer. Conclusions Physical restraint and resultant stress was sufficient to generate some of the effects previously reported for physically immobilised or agitated deer. The values reported here do not differ greatly from those previously reported for rusa deer and can be used as reference values for clinically healthy young farmed male rusa deer.

The effect of different levels of dietary crude protein on urea metabolism of rusa deer (Cervus timorensis)

Two experiments were conducted to measure urea recycling and rumen flow dynamics in young rusa deer fed low (LP) or high (HP) protein diets. Pool size and flux rate of labelled urea. into and out of the blood pool were measured using single intravenous (i.v.) injection solutions containing [C-14] - and [N-15]-urea. A curve peeling technique was used to fit the enrichment of N-15 or specific radioactivity (SRA) of C-14 to exponential equations. Body urea-N pool size was significantly greater (P < 0.05) when a HP, compared to a LP diet, was fed. Urea space, expressed as a percent of live weight, total flux rate of urea through the blood pool and the irreversible loss of urea was similar for both diets. The mean (+/- S.E.M.) concentration of plasma urea-N was greater when animals were fed the HP diet compared to the LP diet (2 1.1 +/- 0.3 versus 14.4 +/- 1.4 mg/100 ml, respectively). Voluntary feed intake and digestibility of dietary components were also measured. Daily dry matter intakes were not affected by the crude protein (CP) content of the diet, although apparent DM digestibility was significantly greater for HP diet fed in both experiments. An intraruminal infusion of CrEDTA was used to determine rumen flow dynamics. Ruminal mean retention time, relative net outflow rate of water and passage rate constant (k(w)) were significantly greater (P < 0.05) when the HP diet was fed compared to the LP diet. The extent of urea metabolism and flux rates of urea between the blood and secondary pools appear similar to those previously reported for other ruminants fed diets contrasting in CP content.
