The Population Biology and Transmission Dynamics of Loa loa [PDF]

, 2017
Endemic to Central Africa, loiasis – or African eye worm (caused by the filarial nematode Loa loa) – affects more than 10 million people. Despite causing ocular and systemic symptoms, it has typically been considered a benign condition, only of public ...

Cutaneous distribution and circadian rhythm of Onchocerca lupi microfilariae in dogs. [PDF]

PLoS Neglected Tropical Diseases, 2013
BACKGROUND: Among the arthropod-borne nematodes infesting dogs, Onchocerca lupi (Spirurida: Onchocercidae) is of increasing zoonotic concern, with new human cases of infection diagnosed in Turkey, Tunisia, Iran and the USA.

Refrigerated modified Knott concentrate enables long-term morphological viability of canine blood microfilariae

Brazilian Journal of Veterinary Medicine, 2023
There are several methods of laboratory diagnosis of filarids, the most used are the thick smear and the Knott method. Both are quick to perform, have a low cost and allow observing the presence, quantifying and analyzing the morphological ...

Developmental regulation of Dirofilaria immitis microfilariae and evaluation of ecdysone signaling pathway transcript level using droplet digital PCR

Parasites & Vectors, 2020
Background Current measures for the prevention of dirofilariasis, caused by the dog heartworm, Dirofilaria immitis, rely on macrocyclic lactones, but evidence of drug-resistant isolates has called for alternative approaches to disease intervention.

Assessing Onchocerca volvulus Intensity of Infection and Genetic Diversity Using Mitochondrial Genome Sequencing of Single Microfilariae Obtained before and after Ivermectin Treatment

Pathogens, 2023
Onchocerciasis is a neglected tropical disease targeted for elimination using ivermectin mass administration. Ivermectin kills the microfilariae and temporarily arrests microfilariae production by the macrofilariae. We genotyped 436 microfilariae from 10

Molecular and morphological characterization of three new species of avian Onchocercidae (Nematoda) with emphasis on circulating microfilariae

Parasites & Vectors, 2021
Background Blood parasites have been the subject of much research, with numerous reports of the presence of microfilariae in the peripheral blood (circulating microfilariae) of birds belonging to many orders.

Microfilariae infection by Acanthocheilonema reconditum and Dirofilaria immitis and their molecular detection in a dog with lymphoma: Case report

Journal of Advanced Veterinary and Animal Research, 2023
Objective: Microfilariae parasites are common in tropical regions, and some species are reported as potentially zoonotic. The diagnosis of filarial infection in dogs by cytology or hematologic tech¬niques showed lower sensibility and specificity, which ...

Malaria-filaria coinfection in mice makes malarial disease more severe unless filarial infection achieves patency [PDF]

, 2005
Coinfections are common in natural populations, and the literature suggests that helminth coinfection readily affects how the immune system manages malaria.

A target repurposing approach identifies N-myristoyltransferase as a new candidate drug target in filarial nematodes [PDF]

, 2014
Myristoylation is a lipid modification involving the addition of a 14-carbon unsaturated fatty acid, myristic acid, to the N-terminal glycine of a subset of proteins, a modification that promotes their binding to cell membranes for varied biological ...
