6) Epidemiology and Control of Guatemalan Onchocerciasis

چکیده
Recent studies on the epidemiology and control of Guatemalan onchocerciasis, chiefly made by the Guatemala-Japan Cooperative Project on Onchocerciasis Research and Control, are reviewed. Epidemiological features of Guatemalan onchocerciasis are summarized as to characteristic altitudinal distribution of endemic areas, disease manifestation, vector taxonomy, biology and transmission dynamic of the disease. Extensive insecticide studies in the field and laboratory demonstrate that the characteristic situations of Guatemalan streams where Simulium ochraceum, the main vector of onchocerciasis, breeds require ingenious methods of larviciding. Finally, the feasibility of an area vector control is indicated by the successful control operation in the San Vicente Pacaya Pilot Area, in which a new fixed-dose larviciding method was applied.

2) A Guatemala-Japan Collaboration Project for Onchocerciasis Research Supported by JICA, Japan
On July 21 of 1975, an agreement was signed to start a collaboration project for the research of onchocerciasis. For this project, Japan decided to send researchers to Guatemala to aid Guatemalan staff of technicians in a research to combat a disastrous filariasis. This disease was discovered in this country by Dr. Rodolfo Robles in the year 1915 and that is why it is known as Robles disease. T...

متن کاملEnzyme-linked immunosorbent assay (ELISA) as a diagnostic tool for Guatemalan onchocerciasis using a bovine filaria (Onchocerca gutturosa) antigen and blood samples collected on filter paper.
An ELISA for human onchocerciasis performed in Guatemala with a crude PBS extract of Onchocerca gutturosa and blood samples collected on filter paper showed a high sensitivity and specificity. A correlation between ELISA and IHA was obtained, and the former proved to be more sensitive than the latter. The ELISA values of blood samples collected on filter paper and of sera obtained from the same...
