Leishmaniasis is a "neglected tropical disease" and serious public health issue in Brazil. While dogs are recognized as particularly important reservoirs, recent reports of domestic cats infected with Leishmania sp. urban areas suggest their participation the epidemiological chain parasite endemic areas. The aim this study was to screen for infection an area where human canine visceral leishmaniasis endemic, followed by identification species circulating cats. We collected peripheral blood,...
Objective: This study sought to evaluate soil microbial activity in an agroforestry system order understand its importance for maintaining fertility. Theoretical Reference: Soil can act as a carbon reservoir, reducing the concentration of CO₂ atmosphere. The greater quantity microorganisms present this environment, better microbiological characteristics development. Therefore, systems represent effective environment capturing carbon, acting CO2 sinks and contributing climate change...
Transfusion-transmitted leishmaniasis has been a concern in regions endemic for the disease. Whether immediate or delayed, risks posed by this mode of transmission call careful assessment. The purpose study was to detect Leishmania infection blood donors living an area and investigate progression disease these individuals. Immunofluorescent antibody test, enzyme-linked immunosorbent assay, rapid polymerase chain reaction were applied 430 initial evaluation. Of those with at least one...
Background Visceral leishmaniasis (VL) in HIV-positive individuals is a global health problem. HIV- Leishmania coinfection worsens prognosis and mortality risk, coinfected are more susceptible to VL relapses. Early initiation of antiretroviral therapy can protect against infection living VL-endemic areas, regular use antiretrovirals might prevent relapses these individuals. We conducted cross-sectional study Petrolina, Brazil, an area, estimate the prevalence asymptomatic cases among...
This study has estimated the risk of Leishmania transmission via blood transfusion in one largest banks Northeastern Brazil, where visceral leishmaniasis is endemic. Five hundred samples from donors were tested for circulating spp. DNA by real-time PCR. Positive a species-specific conventional PCR targeting infantum . Overall, 6.2% (95% CI: 4.1–8.3%) carried and sample species was confirmed as L. No statistically significant differences found relation to gender, sex, education level,...
Visceral leishmaniasis has been reported in all Brazilian regions and, Mato Grosso do Sul State, the occurrence of cases increased significantly. The objective this study was to identify natural infection phlebotomines by Leishmania Ponta Porã, a county bordering Paraguay. By using light CDC and Shannon traps, 185 sandfly females were captured, dissected arranged 107 pools subjected DNA extraction amplification Polymerase chain reaction. From samples amplification, fragment 120 bp...
Leishmania infantum is the etiological agent of visceral leishmaniasis (VL) in Americas with domestic dogs being its major reservoir hosts. The main VL vector sandfly Lutzomyia longipalpis , while other species may play a role disease transmission. Although genetic structure L. populations has been widely evaluated, only few studies have addressed this subject coupled to respective vectors. In study, we analyzed population three endemic areas Brazil and associated it geographic structure.
Peripheral blood of 400 dogs infected with Leishmania and Ehrlichia were analyzed using polymerase chain reaction (PCR), clinical signs characterized.PCR parasitological tests conducted.PCR was positive for in 84.75%, showed that 63.25% 31.75% Ehrlichia, respectively. All animals more than three signs. PCR results negative 15.25% the samples.Conventional peripheral can be used diagnosing canine visceral leishmaniasis combination other techniques, especially uncertain cases need species...
Objective: To determine an algorithm for molecular diagnosis of visceral leishmaniasis (VL) by kinetoplast DNA (kDNA) (RV1/ RV2) and internal transcriber spacer (ITS1) (LITSR/L5.8S) polymerase chain reaction (PCR), complemented ITS1 PCR restriction fragment length polymorphism (RFLP), using peripheral blood or bone marrow aspirate from patients with suspected VL.Methods: Biological samples were submitted to the gold standard VL represented PCR, kDNA RFLP. The obtained seven groups: group I,...
Visceral leishmaniasis (VL) is a severe chronic disease caused by Leishmania (Leishmania) infantum chagasi. Better knowledge on the effects this can help develop adequate clinical management and treatment. Parasitological immunohistochemical studies were performed golden hamsters Mesocricetus auratus infected with bone marrow from individuals VL in State of Mato Grosso do Sul, central-west Brazil. The parasitism spleen, liver, kidneys, lungs, heart brain animals examined. Eighteen inoculated...
Abstract Studies of the geographic distribution sand flies and factors associated with their occurrence are necessary to understand risk leishmaniasis transmission. The objective this study was characterize fly fauna, particularly spatial Lutzomyia longipalpis (Lutz & Neiva), correlate these climate in Dourados municipality, Brazil. collection carried out CDC Light Traps over two periods: at six sites for three consecutive nights each month from August 2012 July 2013; four other April...
Abstract The dog is the main domestic reservoir of Leishmania and font infection for vector, constituting an important host transmission parasite to humans. Non-invasive collection swab samples leishmaniasis diagnosis has been a promising alternative. This study analyzed positivity polymerase chain reaction (PCR) canine in conjunctiva samples. DNA extraction was performed using SDS 20% PCR 13A/13B primers that amplify 120-bp kDNA. Of 77 dogs analyzed, 50 (64.93%) had ocular changes: 25...
This article contains the data regarding Leishmania species identification in human and canine clinical samples from a Brazilian region endemic for (Viannia) spp., (Leishmania) infantum amazonensis, using previously developed approach involving two qPCR assays (qPCR-ML qPCR-ama). The are related to "Real-time PCR differentiate among subgenus, amazonensis: application on samples" [1], include also details of evaluation/diagnosis patients primer sequences used assays. has been determined 27 11...
In the State of Mato Grosso do Sul, Brazil, sand flies and cases visceral (VL) cutaneous (CL) leishmaniases have been reported in almost all municipalities. The aim this study was to analyze geographic distribution VL CL relation fly species found municipalities Sul.We analyzed from 2001 2018 using data Notifiable Diseases Information System (SINAN). Data collected since 2003 on presence vectors (proven or suspected) were provided by Health Secretariat.A total 3566 3030 CL, respectively,...
As Plantas Alimentícias Não Convencionais (PANC) são vegetais com potencial alimentício de crescimento espontâneo, que demandam aprofundamento quanto à propriedade nutricional, para valorização consumo e produção em escala industrial. A inserção PANC na formulação produtos alimentícios como barra cereais, pode fomentar o interesse um público ávido por novos funcionais. O objetivo foi desenvolver avaliar a estabilidade cereais formulada submetida irradiação Cobalto-60. barras foram submetidas...
