“…Setaria digitata is an important filarial nematode living in the peritoneal cavity of cattle and buffaloes, and usually causes mild disease (Perumal et al ., 2016). Infection of abnormal hosts, such as goats, sheep and horses, by this nematode can cause cerebrospinal nematodiasis (CSN) that leads to lumbar paralysis and the eventual death of the animals (Voronin et al ., 2015). This disease inflicts significant economic losses on livestock farmers.…”

Setaria digitata is a filarial parasite that causes fatal cerebrospinal nematodiasis in goats, horses and sheep, resulting in substantial economic losses to livestock farmers. In the present study, the complete mitochondrial (mt) genome of S. digitata from China was determined, characterized and compared with that of S. digitata from Sri Lanka. The identity of the mt genomes was 98.3% between S. digitata from China and Sri Lanka, and the complete mt genome sequence of S. digitata from China was slightly shorter (25 bp) than that from Sri Lanka. For the 12 protein genes, this comparison revealed sequence differences at both the nucleotide (1.4%) and amino acid (2.2%) levels. The present study determined the complete mt genome sequence of S. digitata from China, providing novel genetic markers for the study of the population genetics and molecular epidemiology of S. digitata in animals.

“…In an attempt to identify novel targets for anti-filarial therapeutics, studies have been conducted on Wolbachia – the bacterial endosymbiont residing in Wolbachia -dependent parasites whose absence results in growth, development and fertility defects followed by ultimate death of its host. Our recent study using polymerase chain reaction (PCR)-based multilocus sequence typing, whole-mount immunofluorescence staining and transmission electron microscopy confirmed the absence of Wolbachia in S. digitata (Voronin et al , 2015). Previous reports have highlighted the impact of Wolbachia on energy requirements of its host, W. bancrofti , and its strong influence on mitochondrial evolution due to the vertical co-transmission of mitochondria and Wolbachia (Strubing et al , 2010).…”

Setaria digitata in advancing our knowledge of human lymphatic filariasis

Setaria digitata is a filarial parasite that causes fatal cerebrospinal nematodiasis in goats, sheep and horses, resulting in substantial economic losses in animal husbandry in the tropics. Due to its close resemblance to Wuchereria bancrofti, this nematode is also frequently used as a model organism to study human lymphatic filariasis. This review highlights numerous insights into the morphological, histological, biochemical, immunological and genetic aspects of S. digitata that have broadened our understanding towards the control and eradication of filarial diseases.

“…Setaria digitata was mostly reported in tropical Asian countries, where the vectors are prevalent [5,8,9,11,17,19]. South Korea was the only high latitude non-tropical country where S. digitata was reported in horses [18,26].…”

“…The most common form of migration in infected horses is ocular migration [3,4]. Infected goats and sheep can experience cerebrospinal nematodiasis, which leads to lumbar paralysis and death [5]. Vectors of S. digitata include biting insects like mosquitoes (genera Aedes, Culex, Anopheles, Hyrcanus and Armigeres) [6].…”

A 5-year-old Mongolian mare (Equus caballus Linnaeus, 1758) was observed to have corneal opacity and excessive ocular discharge. An ophthalmic examination revealed a moving thread-like cylindrical worm in the anterior chamber of the right eye. The parasite was successfully removed surgically. The worm was observed under light microscopy and confirmed as Setaria digitata by 12S rRNA gene amplification and sequencing. Phylogenetic analysis demonstrated similarity with Setaria digitata in the National Center for Biotechnology Information (NCBI) GenBank database isolated from other Asian countries. This report is the first confirmed case of equine ocular setariasis by molecular diagnosis in China, which may indicate its presence in livestock and promote research on its epidemiology.
