background: this study was carried out in opi-agu a tropical semi-urban autonomous community comprising of three villages in enugu state, nigeria, between the months of april and june 2010. it was designed to determine the prevalence of onchocerca volvulus infection and assess the perception of the disease among the inhabitants of this community. methods: a total number of 305 individuals compr...
adenylate kinases (adk) are ubiquitous enzymes that contribute to the homeostasis of adeninenucleotides in living cells. in this study, the cloning of a cdna encoding an adenylate kinase from the filariaonchocerca volvulus has been described. using pcr technique, a 281 bp cdna fragment encoding part ofan adenylate kinase was isolated from an o. volvulus cdna library. use of this fragment as a p...
The possible role of microfilarial surface (cuticular) antigens in immuno-diagnosis of human filarial infections has been assessed using microfilariae (mf) of the cattle parasite Onchocerca gibsoni. A Triton X-100 extract of 125I-labeled O. gibsoni mf was reacted with a panel of sera from humans infected with Onchocerca volvulus, Wuchereria bancrofti and Schistosoma japonicum as well as sera fr...
The epidemiological model ONCHOSIM--a model and computer simulation program for the transmission and control of onchocerciasis--has been used to determine the range of plausible values for the reproductive lifespan of Onchocerca volvulus. Model predictions based on different lifespan quantifications were compared with the results of longitudinal skin-snip surveys undertaken in 4 reference villa...
We describe 11 cases of suspected Dracunculus medinensis infection in which the worm recovered was identified as Onchocerca volvulus. Identification was based on morphology of the examined specimen.
Nodding Syndrome (NS) is a childhood neurological disorder characterized by atonic seizures, cognitive decline, school dropout, muscle weakness, thermal dysfunction, wasting and stunted growth. There are recent published information suggesting associations between Nodding Syndrome (NS) with cerebrospinal fluid (CSF) VGKC antibodies and serum leiomidin-1 antibody cross reacting with Onchocerca V...
aspartic proteases are a relatively small group of enzymes which express in various nematodes including onchocerca volvulus. an estimation of the gene copy number corresponding to the ov7a clone, which contains a cdna insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of o. volvulus, was made by slot blot analysis in a closely related species o. gibsonig...
Are Dependent on Onchocerca volvulus and Brugia malayi Bacteria in Wolbachia
Epidemiological evidence has led to the hypothesis that the concurrent and predominant transmission of Onchocerca ochengi by Simulium damnosum s.l. in sub-Saharan Africa could lead to the protection of humans against onchocerciasis caused by Onchocerca volvulus (zooprophylaxis). To gain support for this hypothesis, we investigated whether exposure to O. volvulus could protect cattle from O. och...
The macrofilaricidal effects of local infiltration of high concentrations of chloroquine into the capsule of onchocercal nodules on adult worms of Onchocerca volvulus was determined. Six weeks post infiltration, histological examination of single nodules showed all adult worms to be dead. With nodule conglomerates, there was localized action of chloroquine only on the adult worms in the infiltr...
