Objetivo fundamental de esta nueva técnica es incrementar, en la mayor escala posible, el cultivo de la Barlonella bacilliformis (1) con el fin de producir apreciables cantidades de desarrollo y obtener antígenos en cantidades adecuadas que permitan llevar a cabo estudios inmunoserolócicos en la Enfermedad de Carrión. Fueron Noguchi y Battistini quienes, en 1926 (2), cultivan por primera vez a la B. bacilliformis en el medio que ellos venían empleando para la Leptospira ictero hemorrágica, medio que se conoce como "medio leptospira". En 1929, se señala a los medios corrientes como adecuados para el cultivo del microorganismo; Aldana (3) emplea con éxito el caldo infusión corriente para el cultivo de la sangre del enfermo verrucoso. Un nuevo medio fue estudiado y publicado por Geiman (4) en 1940, el medio puede ser líquido o sólido, pero, en todo caso, emplea la tryptona en vez...

An attempt to study streptococci or other bacteria in certain urinary or urogenital infections by applying the technique of gelation of plasma ( 1) is the main objective of the present work . This new technique provides some interesting data prematurely , as mobility, the trend microaerophilic , aerobic or anaerobic strain to be isolated . Dismissing the bacteria that ferment lactose with gas and using the method of serial dilutions, the gel can serve as a simple and easy technique for counting bacteria urine of patients that lead certain chronic conditions , particularly : pyelonephritis . Planting deep puncture in the gelled evidenced plasma fibrinolytic action (1, 2 ) many strains of enterococci , which may be of varying degrees and forms. In a first group of urinary patients studied , in which Enterococcus urine a small group of strains isolated from the faeces of patients suffering ...

1. The plasma is gelled by the action of the broth "ML" , prepared from peptic digestion of milk and pork bellies . Two . Factors that time , amount of citrate or citrate plasma , influence the phenomenon of gelation . Three . Also the species and individual and pathological factors can influence the Gelation of Plasma. April . That Streptococcus pyogenes , group A, human Gel liquefacta quickly and complete. Rabbit Gel liquefaction resists . May . That the Micrococcus pyogenes and Enterococcus ( Group D ) Gel slowly liquefactan partially or tubular shape ; Having strains or types that make full and quickly. 6. Pseudomonas aeruginosa that liquefactan Gel . 7. Bacillus anthracis liquefactan the gel and produce arborescences and gelatin, these being closely related to such colonial variation. 8. Staphylococci strains that are fast and complete rabbit gel are not as active for human Gel liqu...
