ISOLATION OF PATHOGENS ENTEROBACTERIA FROM AGRO-INDUSTRIALWASTE OF FAMATINA VALLEY-LA RIOJATorrez Lamberti, MF1; Mohamed, F1; Pescaretti, MM1; Delgado, MA1; López, FE2.1Instituto Sup. de Investigaciones Biológicas (INSIBIO-CONICET-UNT). 2Universidad Nac. de Chilecito.E-mail: felopez@fbqf.unt.edu.arThe Famatina Valley´s agroindustrial activity displayed a significant increase in the level of production and in thenew company?s establishment, such as wine and olive oil industries. Consequently, this growth was accompanied bythe need to expand areas of cultivation, manufacturing plants and urbanization of the region to contain the worker andtheir family. These environmental changes increase the risk of the water and soils sources contamination, whichcould displace the autochthonous microbiota and promote the emergence of humans and farm animal?s pathogens. Inthis work we characterized the microbiota present in samples obtained from different sources: i) grape marc of LaRiojana Co wine producing; ii) effluents water samples from Agroarauco Co (olive oil producer) and iii) effluentswastewater treatment ?Aguas de La Rioja?. In the samples from the source i, ii and iii, processed in selective media,we identified a variable number of species belonging to the enterobacteria group, representing a 3.3, 20.6 and 45% ofthe total cultivable microbiota obtained in LB media (per ml of sample), respectively. Moreover, we detectedSalmonella and Shigella strains at a variable number. The presence of these pathogens represents a potential hazardfor the human health, suggesting that the increase these industries production will aggravate this risk if not properlycontrolled.
