A Mathematical Model for the Dynamics of Onchocerciasis With Vector Control and Mass Drug Administration

Journal of Applied Mathematics, Volume 2024, Issue 1, 2024.
In this paper, we investigate the transmission dynamics of onchocerciasis with asymptomatic infected humans using a mathematical model. The model incorporates interventions for treatment and vector control to evaluate the impact of these strategies. We analyse the model to determine the existence and stability of equilibrium points.

Simuliidae (Diptera, Culicomorpha) no Brasil - XII sobre o gênero Thyrsopelma Enderlein, 1934: descrição de T. jeteri Sp.N., considerações sobre o cibário e chave para as pupas Brazilian Simuliidae (Diptera, Culicomorpha) - XII about the genus Thyrsopelma Enderlein, 1934: description of the T. jeteri new species, considerations related with cibarium and key for the pupae

Acta Amazonica, 2005
É acrescentado um novo caráter pupal para a espécie T. hirtipupa (Lutz,1910). É evidenciada a existência de dentes no cibário da fêmea de T. guianense (Wise,1911), principal espécie envolvida na transmissão da filaria Onchocerca volvulus (Leuckart,1893 ...

Patent infections with soil-transmitted helminths and Schistosoma mansoni are not associated with increased prevalence of antibodies to the Onchocerca volvulus peptide epitopes OvMP-1 and OvMP-23

Parasites & Vectors, 2019
Background Ov16 serology is considered a reference method for Onchocerca volvulus epidemiological mapping. Given the suboptimal sensitivity of this test and the fact that seroconversion takes more than a year after infection, additional serological tests

A preliminary analysis of the population genetics and molecular phylogenetics of Onchocerca volvulus (Nematoda: Filarioidea) using nuclear ribosomal second internal transcribed spacer sequences

Memorias do Instituto Oswaldo Cruz, 2007
Nuclear internal transcribed spacer 2 (ITS2) rDNA sequences were used for a molecular phylogenetics analysis of five Onchocerca species. The sister species of the human parasite O. volvulus was found to be the cattle parasite O.

Spatial and temporal diversity of Simulium damnosum s.l. gut microbiota and association with Onchocerca volvulus infection in Cameroon

International Journal of Infectious Diseases
Introduction: The arthropod microbiota plays a crucial role in host physiology, from the complementation of certain metabolic pathways to the bioecological adaptation of vectors.

Beyond Tradition: Exploring Cutting-Edge Approaches for Accurate Diagnosis of Human Filariasis

Pathogens
Filariasis is recognised as a global public health threat, particularly in tropical and subtropical regions. It is caused by infection with a nematode parasite of the superfamily Filarioidea, including Wuchereria bancrofti, Brugia malayi, Onchocerca ...

Mansonella perstans, Onchocerca volvulus and Strongyloides stercoralis infections in rural populations in central and southern Togo

Parasite Epidemiology and Control, 2018
Background: Mansonella perstans, Onchocerca volvulus and Strongyloides stercoralis are widespread helminth parasites in the tropics. Their distribution remains difficult to determine as it may change during national disease control programs and with ...
