ABSTRACT Evidence of spotted fever group (SFG) rickettsiae was obtained from flea pools and individual ticks collected at three sites in northwestern Peru within the focus an outbreak febrile disease humans attributed, part, to SFG rickettsia infections. Molecular identification etiologic agents these samples determined after partial sequencing 17-kDa common antigen gene ( htrA ) as well pairwise nucleotide sequence homology with one or more following genes: gltA , ompA ompB . Amplification...
The goal of this study was to reassess the taxonomic status A. maculatum, triste and tigrinum by phylogenetic analysis five molecular markers [four mitochondrial: 12S rDNA, 16S control region (DL) cytochrome c oxidase 1 (cox1), one nuclear: ribosomal intergenic transcribed spacer 2 (ITS2)]. In addition, phenotypic diversity adult ticks identified as maculatum from geographically distinct populations thoroughly re-examined.Microscopic examination four putative morphotypes distinguishable...
Epidemics of dengue, chikungunya and Zika are a growing threat to areas where Aedes aegypti present. The efficacy chemical control Ae. is threatened by the increasing frequency insecticide resistance. objective this study was determine susceptibility status as well biochemical molecular mechanisms underlying resistance in three populations high risk chikungunya, Peru.Bioassays were conducted on adult evaluate their insecticides used currently or historically for mosquito Peru, including six...
Between May and October 2002, a cluster of acute febrile illnesses occurred in the subtropical Andean foothills Peru. Serologic evidence villages where disease had been documented showed that prevalence IgM antibody to Leptospira ranged from 6% 52%, spotted fever group (SFG) rickettsia 10% 19%, Coxiella burnetii 1% 15%. Measurement IgG antibodies for SFG rickettsiae suggested this was endemic. In contrast, against C. were largely absent. humans, microagglutination tests identified pathogenic...
Introduction Several cases of acute Chagas disease (ACD) have been reported in the Peruvian Amazon basin. Methods The objective was to describe and investigate 6 ACD children from indigenous communities province Datem del Marañón Loreto department (2006-2010). Results mean age 3.6 years. All patients had fever, 4/6 hepatomegaly, 2/6 splenomegaly, 5/6 trypomastigotes Trypanosoma cruzi on thick smears. fatality rate 33.3%. Rhodnius pictipes robustus adults were found inside homes...
Se describe la presencia de Corynosoma obtuscens Lincicome, 1943 (Acanthocephala, Polymor- L i n c o m e , 1 9 4 3 ( A a t h p l P y r - phidae) en el intestino delgado del zorro andino Pseudalopex culpaeus (Molina, 1782) procedente M 7 8 2 ) d San Juan Marcona, Departamento Ica, Perú. Esta es segunda vez que se registra infección natural un mamífero terrestre por C. Perú, lo considera P. como huésped defi nitivo accidental ; además comenta posibilidad éste acantocefalo infecte al hombre.
To determine the circulation of Rickettsia in years 2010 and 2011 border locations four regions ofPeru their clinical epidemiological molecular characteristics.A cross-sectional study was carried out Tumbes, Tacna, Madre de Dios, Loreto. Whole blood samples were obtained from participants for culture indirect immunofluorescence (IIF) testing. The DNA taken leukocytes ectoparasite cultures used, those genes detected that successfully amplified sequenced analyzed.A total 33.8% surveyed...
We developed and standardized an indirect immunofluorescence test for detection of IgG IgTotal diagnosing human Ehrlichiosis. It was used as antigen to DH82 infected cells with Ehrlichia chaffeensis Sapulpa strain; it considered a dilution 1/64 positive. evaluated sera from 130 febrile patients negative Rickettsiosis Carrion disease Ancash, who entered at Instituto Nacional de Salud (Lima, Peru) between 2004 2006. found that 12 (9.2%) were positive Given Ehrlichiosis is emerging the...
Sr. Editor. En el Peru, Ae. aegypti se encuentra distribuido principalmente en la region selvatica y costa norte, llegando hasta Lima (1), no conoce ciudades o localidades al sur de que puedan estar infestadas con este vector. La influencia del clima las variables medioambientales como bajas temperaturas poca precipitacion pluvial son consideradas factores retardarian introduccion posterior establecimiento algunas regiones, es caso sierra pais, altitud tambien puede considerarse una...
