Wild female black flies attracted to a man or an idling automobile were collected at Oita, Japan where five cases of zoonotic onchocerciasis had occurred. Among the five Simulium species captured, 2% of Simulium bidentatum, the predominant species, were infected with filarial larvae. There were at least two types of infective larvae, types A and B, based on morphometric observation. Moreover, m...
Are Dependent on Onchocerca volvulus and Brugia malayi Bacteria in Wolbachia
Adult Onchocerca voluvlus and infective larvae, but not microfilariae contain an immunodominant antigen (33,000 and 21,000 Mr in females, 39,000, 33,000, and 21,000 Mr in males, 133,000 Mr in infective larvae) which is recognized by an Onchocerca-specific mAb. The component is part of the reproductive organs and muscles. 96.2% of onchocerciasis sera contained antibodies detectable by immunoblot...
A case report of complex auricular neuralgia treated with the great auricular nerve and facet blocks
BACKGROUND The great auricular nerve is a cutaneous branch of the cervical plexus originating from the C2 and C3 spinal nerves. It innervates the skin over the external ear, the angle of the mandible and the parotid gland. It communicates with the ansa cervicalis. Great auricular neuralgia is rarely diagnosed in clinical practice and can be refractory. We present a new approach using ultrasound...
River blindness is a seriously debilitating disease caused by the filarial parasite Onchocerca volvulus, which infects millions in Africa as well as in South and Central America. Research has been hampered by a lack of good animal models, as the parasite can only develop fully in humans and some primates. This review highlights the development of two animal model systems that have allowed signi...
Onchocerciasis remains an important public health problem throughout much of sub-Saharan Africa. Nigeria is the country whose population is most afflicted by onchocerciasis; however, little is known concerning the epidemiology of onchocerciasis in this country. Previous studies demonstrated that onchocerciasis in West Africa exists in two forms, which differ in their clinical and epidemiologic ...
The intake and development of Onchocerca volvulus in Simulium pintoi from the Parima mountain region of the Federal Territory of Amazonas in Venezuela, were studied experimentally. When wild females fed on the lower half of the legs and lower third of the back of an onchocerciasis patient harboring 23 and 264 microfilariae per skin snip, respectively, at each site, an average (median) of 14 (ra...
