To determine the rate of appearance of new nodules during a specified period, a follow-up study on onchocercomas that had been removed was carried out in San Vicente Pacaya, Guatemala, between June 1976 and April 1977. Incidence rate, or rate of nodules appearing in initially negative subjects, was studied in relation to the degree of endemicity. Rates in a period of 7—8months in high, medium...

He pointed out the coincidence of the time of biting of the mosquito Culex jatigans, with that of the crowding of the filarial embryos in the peripheral circulation. McKenzie (1881) was able to demonstrate the reversibility of the periodicity of the microfilariae by reversing the sleeping and the waking habits of the infected human host. He also noted the coincidence of the biting hours of the ...

A case of uveitis with microfilariae in the anterior chamber is reported. The organism was recovered from the aqueous and identified as Brugia malayi.

Acanthocheilonema dracunculoides was diagnosed in 2 dogs from Windhoek, Namibia, by acid phosphatase staining of microfilariae. This is the 1st record of A. dracunculoides in Namibia.

BACKGROUND Onchocerciasis is the world's second leading infectious cause of blindness. Its control is currently hampered by the lack of a macrofilaricidal drug and by severe adverse events observed when the lone recommended microfilaricide, ivermectin is administered to individuals co-infected with Loa loa. Therefore, there is the need for a safe and effective macrofilaricidal drug that will be...

Filariasis is a major burden in India in states like Andhra Pradesh. With launching of global filariasis elimination program it has become necessary to use sensitive and accurate methods for diagnosis of filariae as compared to conventional methods. We in this study tried to compare the results of detection of microfilariae with conventional slide methods compared with the ELISA method. 90 samp...

BACKGROUND The filarial parasites Loa loa and Mansonnella perstans are endemic in the central and western African forest block. Loa loa is pathogenic and represents a major obstacle to the control of co-endemic filariae because its treatment can cause fatal complications such as encephalitis. METHODOLOGY/PRINCIPAL FINDINGS 4392 individuals aged over 15 years were studied both by direct examin...
