Chromoblastomycosis is a chronic subcutaneous disease caused by human contact with melanized fungi occurring mainly in tropical and subtropical zones worldwide. This study assessed 12 patients chromoblastomycosis from Rondônia, Brazil, Amazon region. In sum, 83.3% were men, 41.6% Monte Negro city, median age was 52.9 years, time to progression 12.2 years. Lesions located on the lower limbs (75%), verruciform prevalent form (66.6%). After 3 years of treatment itraconazole, two considered...
Human capillariasis caused by Capillaria hepatica (syn. Calodium hepaticum) is a rare disease with no more than 40 cases registered around the world. Classically, has severe symptoms that mimic acute hepatitis. Natural reservoirs of C. are urban rodents (Mus musculus and Rattus novergicus) harbor their eggs in liver. After examining feces 6 riverine inhabitants (Rio Preto area, 8 degrees 03'S 62 53' W to 14'S 52'W) State Rondonia, Brazil, identifying feces, authors decided investigate real...
Chagas disease (CD) is a typical tropical illness caused by Trypanosoma cruzi. The objective of this study was to assess the prevalence in communities two states Brazilian Amazon. Data collection occurred July Alto Juruá region Acre and December Humaitá, Amazonas, 2019. A total 477 participants were included study. In Juruá, triatomine collections analyses T. cruzi infection also carried out. All confirmed cases found state Acre, resulting 1.67. Of these eight cases, seven underwent ECG, all...
INTRODUCTION: Toxoplasma gondii infection is widely prevalent in humans and other animals worldwide. Information on the prevalence of T. scarce some regions Brazil, including riverside communities along Amazon River basin. M METHODS: The 231 people, aged 1-85 years, who were living four Purus River, Lábrea, State Amazonas, was determined. Antibodies against assayed using a commercial enzyme-linked immunosorbent assay (ELISA) kit. hearts brains 50 chickens, which raised free-range...
The prevalence of CND are rocketting over the world, including in young adults. WHO estimates that more than half deaths world caused by CND. authors carried out a cross-sectional study 1,431 school children Brazilian Western Amazon, with and people aged 6 to 16 years. A random sampling 496 individuals was out. OpenEpi platform used calculate sample size, considering p<0.05 presumed 50%. applyied clinical-epidemiological questionnaire, made anthropometric measurements laboratory tests....
Mansonelliasis is caused by Mansonella ozzardi. It widespread in the Amazon region, with a high prevalence. The common exam of thick blood smears stained Giemsa shows low efficacy levels and has been an obstacle to diagnosing individuals parasitemia.In order increase diagnosis efficacy, PCR technique was improved.PCR demonstrated best performance, sensitivity negative predictive values (NPV) 100%, followed filtration through membrane filters, which showed 88.9% NPV 84.6%, when compared smears.
Introduction The aim of this work was to identify possible lymphatic filariasis foci in the western Brazilian Amazonian that could be established from reports Rachou 1950s. study conducted three cities Amazon region - Porto Velho and Guajará-Mirim (State Rondônia) Humaitá Amazonas). Methods For human infection evaluation thick blood smear stained with Giemsa used analyze samples collected 10pm 1am. Polymerase chain reaction (PCR) examine mosquito vectors for presence Wuchereria bancrofti...
Background: The riverine communities of the Amazon comprise different social groups that inhabit rural areas on banks rivers and lakes. Residents usually travel by river to urban are then exposed urbanized diseases such as those caused arbovirus infection. In Brazil, emerging dengue, Zika, chikungunya, infection with Oropouche Mayaro viruses necessitate epidemiological surveillance. This study was aimed at determining frequency positivity for immunoglobulin (Ig)G IgM antibodies against...
The treatment of mansonelliasis is still a challenge because there are few clinical trials for the disease. This double-blind, randomized, placebo-controlled study (phase III trial) was conducted to evaluate effectiveness single oral dose ivermectin (0.15 mg/kg) in reduction Mansonella ozzardi microfilaraemia and occurrence adverse effects infected people compared with control group treated placebo. A total 49 microfilaraemic patients were randomly selected from municipality Lábrea, State...
INTRODUÇÃO: Mansonella ozzardi é uma filária humana que tem como vetor dípteros simulídeos e amplamente distribuída na Amazônia. Não há informações sobre a ocorrência de casos mansonelose no Estado Rondônia, neste trabalho procurou-se investigar situação epidemiológica desta parasitose em áreas urbanas ribeirinhas Amazônia Ocidental. MÉTODOS: Foram examinados 4.452 moradores às margens dos rios Madeira, Mamoré, Guaporé, Machado Preto através da técnica gota espessa sangue. Capturou-se do rio...
Trypanosomes can infect humans and animals. This is the first record of occurrence Trypanosoma evansi in Rondônia.Blood samples were collected from 7 dogs 22 humans. Furthermore, triatomines tabanids collected.It was observed that 42.8% tested positive for T. 14.3% presented mixed infection; 15% flagellates identified as cruzi TCI (3 specimens), TCI, rangeli (1 specimen), one with TCV. Two infected theileri.These findings may benefit vector control strategies.
ABSTRACT Schistossomiasis is a parasitic disease, caused by helminths of the genus Schistosoma and transmitted in Brazil snails Biomphalaria. The municipality Ouro Preto do Oeste, Rondônia, Brazilian Amazon Region, has unusually registered more than 900 cases schistosomiasis last 10 years. aim this study was to investigate de potential transmission schsitosomiasis Oeste. A total 1,196 people risk area for disease were requested answer clinical-epidemiological survey collect feces samples...
