Swine cysticercosis, a severe zoonotic disease which is part of the Taenia solium life cycle, causes major economic losses in pig husbandry. Throughout South America, farmers diagnose cysticercosis by examining the tongues of their pigs for cysticercus nodules. Farmers do not bring pigs believed to be infected to the slaughterhouse for fear of confiscation.(More)
Sera from 71 patients with surgically confirmed hydatid disease (which is caused by Echinococcus granulosus) were studied by an enzyme-linked immunoelectrotransfer blot (EITB) assay. Sera from patients either with other cestode infections or with another illness were used as controls. Results of the EITB test for hydatidosis were compared with those of the(More)
We compared the epidemiologic characteristics of cyclosporiasis and cryptosporidiosis in data from a cohort study of diarrhea in a periurban community near Lima, Peru. Children had an average of 0.20 episodes of cyclosporiasis/year and 0.22 episodes of cryptosporidiosis/year of follow-up. The incidence of cryptosporidiosis peaked at 0.42 for 1-year-old(More)
Taenia solium taeniasis/cysticercosis is a zoonotic disease complex in which the pig is an obligate intermediate host. The infection is widespread, particularly in the developing world, and neurocysticercosis is a major cause of human neurologic disease where the parasite is endemic. Despite easy availability, effective anti-parasitic drugs have not been(More)
BACKGROUND Human noroviruses are among the most common enteropathogens globally, and are a leading cause of infant diarrhea in developing countries. However, data measuring the impact of norovirus at the community level are sparse. METHODS We followed a birth cohort of children to estimate norovirus infection and diarrhea incidence in a Peruvian(More)
Cysticercosis contributes to higher epilepsy rates in developing countries than in industrialized ones, yet no estimate exists for the associated burden of disease. We used epidemiological data on neurocysticercosis in Peru to calculate the burden of disease and applied our model to the other countries of Latin America where neurocysticercosis is endemic to(More)
The prevalence of human, canine, and ovine echinococcosis was determined in an endemic area of the Peruvian Andes where control programmes have not been operational since 1980. Prevalence of infection in humans was determined using portable ultrasound, chest X-rays, and an enzyme-linked immunoelectrotransfer blot (EITB) assay. Canine and ovine echinococcal(More)
The prevalence and characteristics of human taeniasis/cysticercosis and porcine cysticercosis were assessed in an endemic area of the Peruvian highlands. Individuals from 10 communities had stool examinations (N = 2,951) and serologic testing for Taenia solium antibodies (N = 2,583). The total porcine population present (N = 703) was also examined by(More)
Human, canine and ovine echinococcosis prevalence was determined in a highland community located in the central Peruvian Andes during 1997 and 1998. Human echinococcosis was determined using portable ultrasonography, chest X-ray examination, and an enzyme-linked immunoelectrotransfer blot (EITB) assay. Canine echinococcosis was determined using microscopy(More)
BACKGROUND We conducted a study of congenital Trypanosoma cruzi infection in Santa Cruz, Bolivia. Our objective was to apply new tools to identify weak points in current screening algorithms, and find ways to improve them. METHODS Women presenting for delivery were screened by rapid and conventional serological tests. For infants of infected mothers,(More)
