RESUMEN
According to the data available at the World Data Center for Microorganism-WDCM from the World Federation for Culture Collection-WFCC, Chile has four registered culture collections that preserve 2777 microbial strains. At the global point of view, the culture collections in Chile are in different level of operation regarding its own infrastructure and compliancy with quality standards for preservation of strains and for services provide. The absence of funding to support the preservation of the Chilean microbial assets is a key issue for the development of the Chilean bioeconomy. Considering this, the Chilean culture collections started working together to establish the Chilean Network of Microbial Culture Collections (RCCCM, acronym in Spanish). In this note, the establishment and operation of the RCCCM is presented and discussed.
De acuerdo con los datos disponibles en el World Data Center for Microorganism-WDCM de la Federación Mundial para la Colección de Cultivos - WFCC, Chile tiene cuatro colecciones de cultivos registradas que preservan 2777 cepas microbianas. Desde el punto de vista global, las colecciones de cultivos en Chile se encuentran en diferentes niveles de operación con respecto a su propia infraestructura y cumplimiento con estándares de calidad para la preservación de las cepas y para los servicios que proporcionan. La ausencia de financiamiento para apoyar la preservación de los activos microbianos chilenos es un tema clave para el desarrollo de la bioeconomía chilena. Considerando esto, las colecciones chilenas de cultivos comenzaron a trabajar conjuntamente para establecer la Red Chilena de Colecciones de Cultivos Microbianos (RCCCM). En esta nota se presenta y discute el establecimiento y funcionamiento de la RCCCM.

In the present study, we determined the frequency of superficial and cutaneous mycoses and their etiologic agents during a 7-year period (2002-2008) in Natal, Brazil. A total of 1,717 specimens of skin, nail, and hair were collected from 1,382 patients with suspected mycoses lesions and were then subjected to direct microscopy and culture.

The authors studied the killer effect of nine standard strains of yeasts on 146 samples of Candida albicans isolated from the following clinical specimens: oral mucosa, feces, bronchial wash, sputum, vaginal secretion, urine, skin lesion, nail lesion and blood. Using this system it was possible to differentiate 23 biotypes of Candida albicans. The biotypes 211, 111 and 811 were most frequently isolated. Most of the samples of C. albicans (98.6 per cent) were sensitive to at least one or more of the nine killer strains. Using the killer system it was possible to show that two patients harbored the same killer biotypes, 111 and 211, respectively, in different clinical specimens and another patient harbored the same biotype (211) in bloodcultures effected in different ocasions. The utilization of the killer system to differentiate types among species of pathogenic yeasts can be a useful method to establish the eventual source of infection, and it is a valuable tool to control and watch for nosocomial infections caused by yeasts.
