Feb 8, 2015 · Blood and tissue filarial nematodes are roundworms that infect humans. These organisms are transmitted via a blood-sucking arthropod vector such as a mosquito, midge, or fly. The filarial nematodes infect the subcutaneous tissues, deep connective tissues, body cavities, and lymphatic system.

The filariae are thread-like parasitic nematodes (roundworms) that are transmitted by arthropod vectors. The adult worms inhabit specific tissues where they mate and produce microfilariae, the characteristic tiny, thread-like larvae.

The traditional method of diagnosis of most filarial nematode infections continues to be detection of microfilariae on stained thick and thin blood films. Proper collection and processing of blood specimens are essential for a reliable diagnosis.

Aug 17, 2022 · This document discusses tissue/somatic nematodes that infect humans, focusing on filarial nematodes. It describes the key characteristics of filarial nematodes including their two-host life cycle using an intermediate insect host and definitive human host.

The important tissue nematodes Wuchereria, Onchocerca, and Loa are called the “filarial worms,” because they produce motile embryos called microfilariae in blood and tissue fluids. These organisms are transmitted from person to person by bloodsucking mosquitoes or flies.

Filarioidea are a superfamily of threadlike, parasitic nematodes (worms), with numerous families, genera, and species. Their definitive hosts are vertebrates, but only a few filarial species infect humans. Threadlike adult filarial worms reside in lymphatic or subcutaneous tissues.

Three species of Mansonella, a vector-borne filarial nematode genus, are associated with human infections: M. ozzardi, and M. perstans (= Dipetalonema perstans), and M. streptocerca (=Dipetalonema streptocerca). These species vary in their …

Mar 20, 2024 · Human filariasis encompasses parasitic infections caused by several species of tiny, thread-like nematode worms that affect the skin, lymphatic vessels, and connective and subcutaneous tissues. Although rarely a direct cause of death, some filarial worms, especially the three species causing lymphatic filariasis and the one causing ...
