Objective. To determine the epidemiological and clinic characteristics of gastroenteritis caused by Vibrio parahaemolyticus strains of the pandemic group in Peru. Material and methods. Clinical and laboratory records were searched in 100 cases of gastroenteritis caused by V parahaemolyticus, either of the pandemic or non pandemic group. Clinical and epidemiological data were collected and statistical analysis was done to evaluate if the severity of illness was associated with the pandemic group. Results. Epidemiological data were collected in 85% of cases, and clinical data were only available in 37% of cases, mainly on those hospitalized. Cases associated with the pandemic strains had a higher probability of liquid stools (96.3% vs. 62.5%, p<0.05), moderate or severe dehydration (100% vs. 60%, p<0.05), and hospital care (98% vs. 42.9%, p<0.0001). Cases aged thirty or older were associat...

Home based interventions are advocated in rural areas against a variety of diseases. The combination of different interventions might have synergistic effects in terms of health improvement and cost effectiveness. However, it is crucial to ensure cultural acceptance. The aim of the study was to develop an effective and culturally accepted home-based intervention package to reduce diarrhoea and lower respiratory illnesses in children. In two rural Peruvian communities we evaluated the performance and acceptance of cooking devices, household water treatments (HWT) and home–hygiene interventions, with qualitative and quantitative methods. New ventilated stove designs reduced wood consumption by 16%. The majority of participants selected solar water disinfection as HWT in a blind tasting. In-depth interviews on hygiene improvement further revealed a high demand for kitchen sinks. After one...

The main aim of this study was to establish the resistance levels to antimicrobial agents, in 222 non-pathogenic E. Coli strains of fecal origin in Peru. The proportion of resistance found to the evaluated antimicrobials was ampicillin (62.6%), cotrimoxazole (48,6%), tetracycline (43,0%) and chloramphenicol (15,8%). We emphasize the high resistance levels found for quinolones: 32% for nalidixic acid (NAL) and 12% for ciprofloxacin (CIP). These high levels of quinoloneresistance in non-pathogenic strains isolated from children in this age group highlight the extensive use and the impact of the intake of this kind of antimicrobials in the community, showing the potential risk of the loss of their utility in the area.
