Scanning Electron Microscopy of Onchocerca volvulus Microfilariae from Guatemala

چکیده
Microfilariae of Onchocerca volvulus from Guatemala were examined by scanning electron microscope. There are numerous transverse striations on the cuticular surface. The number of annulations varies from 325 to 357. The anterior end forms a round cephalic cap which bears a V-shaped hook. Two small openings are present on the cephalic cap. They are probably the openings of one of the amphidial channels and buccal cavity. The tail tapers gradually and ends in the terminal appendage which lacks the transverse striations. The geographical difference in surface structure of O. volvulus microfilariae was discussed.

The effects of long-term community level treatment with ivermectin (Mectizan) on adult Onchocerca volvulus in Latin America.
The objective of this study was to examine nodules from Mexico, Guatemala, and Ecuador collected over a one-year period (2001) to determine the effects of semi-annual ivermectin treatments on Onchocerca volvulus macrofilarial populations. Nodules were sectioned, stained with hematoxylin and eosin, and histologic findings were compared between countries and with historical data prior to the intr...

Onchocerciasis is a major cause of blindness worldwide, and much of the blindness is caused by onchocercal chorioretinitis. In an experimental animal model for ocular onchocerciasis, intravitreal injections of 10,000 live Onchocerca volvulus microfilariae isolated from infected humans into the eyes of cynomolgus monkeys (Macaca fascicularis) resulted in patchy, progressive loss of retinal pigme...
متن کامل5) Review of the Biology and Ecology of Adult Blackflies in Relation to the Transmission of Onchocerciasis in Guatemala
Recent studies on the biology and ecology of adult blackflies in relation to the transmission of human onchocerciasis in Guatemala are reviewed. First, earlier studies on the transmission of the disease since its discovery by Dr. R. Robles in 1915 are outlined. Second, eleven blackfly species caught on humans are evaluated for vector status on the basis of their natural and experimental infecti...
متن کاملElimination of Onchocerca volvulus Transmission in the Huehuetenango Focus of Guatemala
In Latin America, onchocerciasis is targeted for elimination by 2012 through twice-yearly mass treatment of the eligible population with ivermectin. In Guatemala, two of the four historical endemic foci have demonstrated elimination of transmission, following World Health Organization guidelines. Using established guidelines ophthalmological, serological, and entomological evaluations were cond...
متن کاملSuccessful Interruption of Transmission of Onchocerca volvulus in the Escuintla-Guatemala Focus, Guatemala
BACKGROUND Elimination of onchocerciasis (river blindness) through mass administration of ivermectin in the six countries in Latin America where it is endemic is considered feasible due to the relatively small size and geographic isolation of endemic foci. We evaluated whether transmission of onchocerciasis has been interrupted in the endemic focus of Escuintla-Guatemala in Guatemala, based on ...
