1. Evaluation of the recombinant antigens Wb14 and WbT for the capture antibody diagnosis of lymphatic filariasis
BACKGROUND Lymphatic filariasis (LF) is a parasitic disease caused mainly by the Wuchereria bancrofti worm and that affects up to 120 million people worldwide. LF is the second cause of chronic global deformity, responsible for 15 million people with lymphedema (elephantiasis) and 25 million men with scrotal hydrocele. Its diagnosis is still associated wit

2. Wuchereria bancrofti infection in Haitian immigrants and the risk of re-emergence of lymphatic filariasis in the Brazilian Amazon
Abstract INTRODUCTION: Lymphatic filariasis (LF) is a public health problem in Haiti. Thus, the emigration of Haitians to Brazil is worrisome because of the risk for LF re-emergence. METHODS: Blood samples of Haitian immigrants, aged ≥18 years, who emigrated to Manaus (Brazilian Amazon), were examined using thick blood smears, membrane blood filtration

3. Detection of Wuchereria bancrofti DNA in paired serum and urine samples using polymerase chain reaction-based systems
The Global Program for the Elimination of Lymphatic Filariasis (GPELF) aims to eliminate this disease by the year 2020. However, the development of more specific and sensitive tests is important for the success of the GPELF. The present study aimed to standardise polymerase chain reaction (PCR)-based systems for the diagnosis of filariasis in serum and urine

4. Ocorrência de formas imaturas de culicídeos (Insecta: Diptera) na região nordeste do Brasil
A família Culicidae é representada por aproximadamente 3.610 espécies, dentre as quais muitas estão envolvidas na transmissão de patógenos e parasitos, apresentando assim grande importância médico-veterinária. No Brasil, o Estado de Pernambuco é considerado área endêmica para diversas doenças transmitidas por mosquitos como, por exemplo, as fila

5. Evaluation of diagnostic tests for Wuchereria bancrofti infection in Brazilian schoolchildren
Introduction Since the launch of the Global Programme to Eliminate Lymphatic Filariasis, more than 70% of the endemic countries have implemented mass drug administration (MDA) to interrupt disease transmission. The monitoring of filarial infection in sentinel populations, particularly schoolchildren, is recommended to assess the impact of MDA. A key issue i

6. Optimisation of an asymmetric polymerase chain reaction assay for the amplification of single-stranded DNA from Wuchereria bancrofti for electrochemical detection
Single-stranded DNA (ssDNA) is a prerequisite for electrochemical sensor-based detection of parasite DNA and other diagnostic applications. To achieve this detection, an asymmetric polymerase chain reaction method was optimised. This method facilitates amplification of ssDNA from the human lymphatic filarial parasite Wuchereria bancrofti. This procedure prod

7. Survey of Bancroftian filariasis infection in humans and Culex mosquitoes in the western Brazilian Amazon region: implications for transmission and control
IntroductionThe aim of this work was to identify possible lymphatic filariasis foci in the western Brazilian Amazonian that could be established from the reports of Rachou in the 1950s. The study was conducted in three cities of the western Brazilian Amazon region - Porto Velho and Guajará-Mirim (State of Rondônia) and Humaitá (State of Amazonas).MethodsF

8. Influence of anti-filarial chemotherapy strategies on the genetic structure of Wuchereria bancrofti populations
Lymphatic filarial (LF) parasites have been under anti-filarial drug pressure for more than half a century. Currently, annual mass drug administration (MDA) of diethylcarbamazine (DEC) or ivermectin in combination with albendazole (ALB) have been used globally to eliminate LF. Long-term chemotherapies exert significant pressure on the genetic structure of pa

9. Assessment of family and neighbors of an individual infected with Wuchereria bancrofti from a non-endemic area in the city of Maceió, Brazil
The family and neighbors of a patient infected with W. bancrofti microfilariae were assessed aiming to evaluate the occurrence of cases of lymphatic filariasis in a non-endemic area in the city of Maceió, in the Brazilian state of Alagoas. The patient had previously lived in an endemic focus; however, he has been living in an area where the parasite has nev

10. Comparison of tests for the detection of circulating filarial antigen (Og4C3-ELISA and AD12-ICT) and ultrasound in diagnosis of lymphatic filariasis in individuals with microfilariae
Significant advances were made in the diagnosis of filariasis in the 1990s with the emergence of three new alternative tools: ultrasound and tests to detect circulating antigen using two monoclonal antibodies, Og4C3 and AD12-ICT-card. This study aimed to identify which of these methods is the most sensitive for diagnosis of infection. A total of 256 individu

11. Mudanças de paradigmas na filariose bancroftiana
Ao longo do tempo, a maneira como se entende um determinado assunto passa por modificações através da pesquisa científica. Na maioria das vezes, essas mudanças causam pequenas diferenças na estrutura total do tópico em questão. Outras vezes, entretanto, ocorrem mudanças revolucionárias que não só alteram a compreensão do assunto em si, mas promo

12. Observações preliminares de fluidos incubados com Wuchereria bancrofti usando o teste imunocromatográfico
Para a valiar o desempenho do teste imunocromatográfico para filariose, vermes adultos de Wuchereria bancrofti foram incubados em diferentes condições. Os testes foram fortemente positivos com fluidos de incubação de fêmeas vivas e danificadas mecanicamente. Resultados negativos foram obtidos com fluidos de todos os machos e de fêmeas mortas intactas.
