1. OCCURRENCE OF FILARID PARASITES IN HOUSEHOLD AND SHELTERED DOGS IN THE CITY OF JOINVILLE – SANTA CATARINA, BRAZIL
Resumo Dentre os diversos nematódeos filarídeos que parasitam cães, alguns podem ser apatogênicos como Acanthocheilonema reconditum e outros como Dirofilaria immitis podem levar esses animais a óbito, além de terem potencial zoonótico. Nesse sentido, o objetivo deste trabalho foi realizar um levantamento da ocorrência de filarídeos em cães resident

2. Dirofilaria immitis infection in dogs in Algodoal Island, Brazilian Amazon
RESUMO: Dirofilaria immitis, um parasito que infecta principalmente canídeos domésticos ou selvagens, embora também possa infectar felinos e humanos, é frequente em muitas áreas do Brasil. O objetivo deste estudo foi determinar a ocorrência da infecção natural em cães provenientes do complexo da Ilha de Algodoal-Maiandeua, região litorânea do esta

3. Sensitivity of diagnostic methods for Mansonella ozzardi microfilariae detection in the Brazilian Amazon Region
BACKGROUND The human filarial worm Mansonella ozzardi is highly endemic in the large tributaries of the Amazon River. This infection is still highly neglected and can be falsely negative when microfilariae levels are low. OBJECTIVES This study investigated the frequency of individuals with M. ozzardi in riverine communities in Coari municipality, Brazilian

4. Mansonelliasis, a neglected parasitic disease in Haiti
Reported in Haiti as early as 1923, Mansonella ozzardi is still a neglected disease ignored by the health authorities of the country. This review is an update on the geographic distribution of the coastal foci of mansonelliasis in Haiti, the epidemiological profile and prevalence rates of microfilariae in people living in endemic areas, the clinical impact o

5. 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

6. Biological rhythms and vector insects
The adjustment of all species, animals and plants, to the Earth’s cyclic environments is ensured by their temporal organisation. The relationships between parasites, vectors and hosts rely greatly upon the synchronisation of their biological rhythms, especially circadian rhythms. In this short note, parasitic infections by Protozoa and by microfilariae hav

7. 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

8. Relações vetor-hospedeiro de Rhodnius brethesi Matta, 1919 (Hemiptera: Reduviidae: Triatominae), em piaçabais do médio rio Negro, Amazonas, Brasil
Rhodnius brethesi Matta, 1919 is among the species of Triatominae Amazon with great epidemiological importance, especially in regions of middle and upper Rio Negro, due to been vectors of Trypanosoma cruzi Chagas, 1909 and Trypanosoma rangeli Tejera, 1920. R. brethesi are associated with palm Leopoldinia piassaba Wallace, which represents an important source

9. 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

10. Localization of Brugia malayi (sub-periodic) adults in different organs of Mastomys coucha and its influence on microfilaraemia and host antibody response
Lymphatic filariasis caused by nematode parasites Wuchereria bancrofti or Brugia malayi is a spectral disease and produces wide range of immune responses and varying levels ofmicrofilaraemia in infected individuals. The relationship between the immune response of host and the developmental stage of the parasite as well as the microfilariae (mf) density and s

11. Longitudinal evaluation of repellent activity of Ocimum gratissimum (Labiatae) volatile oil against Simulium damnosum
To determine the repellent activity of Ocimum gratissimum volatile oil against Simulium damnosum (blackflies), a 12 month (January-December 2003) field study was conducted in three onchocerciasis endemic communities (Idomido, Obio camp, and Ikot Adaha) in Ini Local Government Area of Akwa Ibom State, Nigeria. The result revealed that topical application of 2

12. Diferenciação histoquímica em microfilárias de Dipetalonema reconditum e Dirofilaria immitis em cães (Canis familiaris) / Differentiation in microfilariae of Dipetalonema reconditum and Dirofilaria immitis in dogs (Canis familiaris).
As microfilárias quando encontradas devem ser identificadas corretamente, para realização de um diagnóstico preciso, já que o Dipetalonema é apatogênico e a infecção não requer tratamento, enquanto a Dirofilariose, conhecida como Doença do Verme do Coração, pode levar o cão à morte. Este trabalho teve como objetivo contribuir ao diagnóstico p
