| cutaneous leishmaniasis in the peruvian andes: risk factors identified from a village cohort study. | risk factors for cutaneous leishmaniasis were identified from a comparative study of transmission rates in 27 villages in the departments of lima, ancash, and piura in peru. to evaluate regression analysis as a tool for the incrimination of sand fly vectors in the absence of other biologic evidence, univariate and multivariate logistic regression analyses were used to identify which of 14 variables (the abundance of nine sand fly species, four social factors, and region) predicted transmission r ... | 1997 | 9063368 |
| survey of bartonella species infecting intradomicillary animals in the huayllacallán valley, ancash, peru, a region endemic for human bartonellosis. | the natural cycle of bartonella bacilliformis remains uncertain, and the suspected existence of animal reservoirs for the bacterium has never been convincingly demonstrated. we conducted a survey of bartonella species infecting intradomicillary animals in a bartonellosis-endemic region of peru, obtaining blood from 50 animals living in the homes of 11 families whose children had recently had bartonellosis. bartonella-like bacteria were recovered from four of nine small rodents included in the st ... | 1999 | 10344656 |
| distribution of hydatidosis and cysticercosis in different peruvian populations as demonstrated by an enzyme-linked immunoelectrotransfer blot (eitb) assay. the cysticercosis working group in peru (cwg). | a serosurvey for human hydatidosis and cysticercosis was performed in different regions of peru. those regions included a known endemic area for cystic hydatid disease, a cooperative in the central peruvian andes near the city of tarma, department of junin; three areas endemic for cysticercosis in the departments of ancash, cuzco, and san martin, where the status of hydatid disease is not well defined; and an urban shantytown near lima, where neither zoonosis is known to be present. a seropreval ... | 1994 | 7810822 |
