Binsztein Description An account of the resource Vibrio cholerae muestra gran diversidad serológica en base a su antígeno somático O, conociéndose al menos 200 serogrupos. De éstos, solamente O1 y O139 son causantes de epidemias o pandemias. En Latinoamérica el serogrupo O1 reapareció en 1991, tras cien años de no presentar brotes en el continente. Esta bacteria sobrevive y se multiplica asociada al plancton, independientemente de la aparición de infecciones humanas. Desde la década del noventa, en Tucumán, se detectaron casos esporádicos de diarrea por Vibrio cholerae no-O1. El objetivo del presente trabajo fue estudiar la posible relación entre la presencia de especímenes de fitoplancton, variables fisicoquímicas y aislamientos de Vibrio cholerae en ríos de Tucumán. Se realizaron 18 campañas en los ríos Lules y Salí entre 2003-2005. Se estudiaron las variables fisicoquímicas del agua (pH, temperatura, conductividad y oxígeno disuelto), el fitoplancton (riqueza y frecuencia relativa) y las cepas aisladas de V. cholerae. Los resultados evidenciaron diferencias en la calidad del agua, observándose períodos de anoxia en el río Salí. Las diatomeas sobresalieron en la mayoría de los meses y generalmente estuvieron en porcentajes superiores al 85 %. Sólo se aisló Vibrio cholerae no-O1, no-O139, detectándose más frecuentemente en los meses cálidos, con pH alcalino, aún con baja concentración de oxígeno.Vibrio cholerae shows a great serologic diversity in relation to his O somatic antigen and we know at least 200 serogroups. About these, only O1 and O139 are responsible of epidemics and pandemics. The serogroup O1 reemerged in Latin America in 1991 after being absent from the continent for nearly a century. This bacterium survives and grows up associated to plankton, independently of appearance of human infections. From 90 th decade, there were sporadic cases of diarrhea because of Vibrio cholerae O1 in Tucumán. The aims of this paper were to study the possible relation between phytoplankton species, physico-chemical variables and V. cholerae isolations in rivers of Tucumán. There were 18 sampling in the rivers Salí and Lules from 2003 to 2005. Physico-chemical variables of water (pH, temperature, conductivity and dissolved oxygen), phytoplankton (richness and relative frequency) and V. cholerae isolations were studied in this paper. Results showed differences in water quality, with anoxic periods in the River Salí. Diatoms were conspicuous in almost all months and generally there were in percentages upper 85 %. Just Vibrio cholerae non-O1, non-O139 was isolated, specially in months warmer with alkaline pH and also with dissolved oxygen low concentration.
