Las aguas de uso doméstico en los tres barrios del Distrito Santo Toribio, provienen de: Red de agua no sometida a tratamiento, manantiales, reservorios, arroyuelos, y no se realiza control sanitario permanente. El objetivo es conocer la calidad higiénica de las aguas y prevención. Se examinó 276 muestras, utilizando métodos cualitativos y cuantitativos de APHA, OMS y OPS. Los resultados indican que: El 46.4 % roraptas para consumo y son aprovechados por 1,200 habitantes, pertenecen a red de aguas no sometidas a tratamiento y manantiales. El 53.6 % no as aceptable para consumo y son utilizados por 800 pobladores, pertenecen a los reservorios y arroyuelos.

The aim of this study was to isolate and characterize phenotypically and molecularly the pathogen Edwardsiella anguillarum, as well as to determine the anatomo-histopathological lesions in tilapia (Oreochromis niloticus) cultivated with biofloc technology in the northern area of Lima, Peru. Five isolated bacterial strains were isolated and characterized by conventional biochemical techniques and by the API 20E system. E. anguillarum was identified from internal organs using biochemical and molecular techniques. The most frequent external clinical signs were bilateral exophthalmia, erythema in the pectoral fins and around the anus. Internally, whitish nodules in the heart and liver were observed. The histopathological study revealed necrosis in the branchial lamellae, spleen, intestine, posterior kidney and gonad, as well as the presence of an inflammatory reaction of granulomatous type i...
