GARCIA P, Ana; PEDREROS R, Leoncio  e  HUAPAYA, Blanca. Vibrio cholerae No O1 en muestras de aguas no cloradas consumidas por pobladores de las localidades de Santa y Coishco (Ancash), 2003 - 2004. Rev. perú. med. exp. salud publica [online]. 2006, vol.23, n.3, pp.168-172. ISSN 1726-4634.

Objective: Identify the presence of Vibrio cholerae in unchlorinated water samples intended for human consumption in locations of Santa and Coishco. Materials and methods: Between July 2003 and June 2004, water samples were collected weekly from seven water wells with manual pumps and from six wells with reservoir. Residual chlorine levels were measured at the site using a Hatch chlorine comparing tool, chlorimetric method, using DPD 1 pills. Well samples were cultured according to National Institute of Health (INS Lima) standard operating procedures. Isolated strains were submitted to the INS for diagnostic confirmation and serologic testing. Results: A total of 308 drinking water samples from both districts were included (201 from wells with manual pumps and 107 with reservoir). Isolates were obtained from 70(22,7%) samples. Aeromonas caviae 34(11,0%), Aeromonas hidrophyla 17(5,5%) and Vibrio cholerae non-O1 19(6,2%) were detected; V. cholerae O139 was not found. Vibrio cholerae non-O1 was isolated in 11(5,5%) samples from manual pump wells and 8(7,4%) from wells with reservoirs. Conclusions: Drinking water from tubular wells represents a potential reservoir for bacteria, such as Aeromonas and Vibrio cholerae, highlighting the need for disinfection before use.
