| seroreactivity of peruvian sheep and goats to small ruminant lentivirus-ovine progressive pneumonia virus. | sera from 3,369 sheep and 1,394 goats in peru were examined by agar-gel immunodiffusion for antibodies to ovine progressive pneumonia virus (oppv). the point prevalence rates for antibodies to oppv in sheep were 1.7% to 40.6% (mean, 19.02%) in the 7 flocks studied, whereas for goats, the point prevalence rates for antibodies that cross-reacted with oppv in 12 herds were 0.0% to 45.1%. for sheep, a direct association between increasing age and increasing seroreactivity to oppv was established, an ... | 1987 | 3105369 |
| identification of risk factors for cystic echinococcosis in a peri-urban population of peru. | we conducted a questionnaire-based case-control study to identify risk factors for cystic echinococcosis (ce) in lima, peru during july-december 2005. data were obtained from 32 cases and 64 controls. multivariate conditional logistic regression showed that having owned > or =10 dogs [adjusted odds ratio (aor) 8.7, 95% ci 1.3-57.5) and raising sheep (aor 5.9, 95% ci 1.2-28.1) were independently associated with ce. the belief that ce could be transmitted by food (aor 0.1, 95% ci 0.01-0.7) and bre ... | 2008 | 17949765 |
| [practices, knowledge and attitudes about human hydatidosis in peru]. | between july 2005 and june 2006, a case-control study was carried out to identify risk factors for hydatidosis in lima, peru. as a result, 32 cases were matched according to age, sex and birthplace in 64 controls. the participants were interviewed using a questionnaire designed to evaluate environmental and behavior factors associated to hydatidosis. by using multiple conditional logistic regression, it was determined that the owners of >or=10 dogs in a rural area (aor=8.7; 95% cl=1.3-57.5) and ... | 2008 | 18418456 |
| molecular identification of echinococcus isolates from peru. | genetic variations in tapeworms causing cystic echinococcosis in peru were investigated. seventy one larval isolates collected from different intermediate hosts and geographic regions were identified by the dna sequencing of genes for mitochondrial cytochrome c oxidase subunit 1 (cox1) and nuclear elongation factor 1 alpha (ef1a). the g7 genotype (e. canadensis pig strain) was found for the first time in pigs reared in the city of lima. echinococcus granulosus sensu stricto (sheep strain or g1) ... | 2009 | 19567235 |
| [epidemiological and clinical features of brucellosis in 39 family groups]. | clinical epidemiological evaluations on brucellosis, done during the last five years in endemic areas in lima (peru), in 39 families with 232 members, have let us observe a high rate of symptomatic infection 118/232 (50.9%) and has also let us identify, as risk factors to contract the disease; age older than 10 years 97/190 (56.3%) versus 11/42 (26.1%); in younger than 10 years of age (p less than 0.05) and families with 5 or less members 40/54 (74.0%) versus 78/175 (44.5%) of more numerous fami ... | 1989 | 2490429 |
