Bacteria composition and diversity in the gut of sand fly: impact on Leishmania and sand fly development

International Journal of Tropical Insect Science, 2020
Sand flies (Diptera: Psychodidae: Phlebotominae) are the only proven vectors of leishmaniasis. Leishmania parasites develop and differentiate in the sand fly gut where they reside alongside the vector's gut bacteria. Gut bacteria are important to sand fly's nutrition, oviposition, and defence against pathogens.

Lutzomyia longipalpis (Sand Fly)

Trends in Parasitology, 2020
Lutzomyia longipalpis appears primarily in Central and South America and is the main vector of visceral leishmaniasis (VL) caused by Leishmania infantum. In Brazil, the country reporting the highest number of human VL cases in the region, this sand fly is reported in 24 of 27 states. L.

Establishment and maintenance of sand fly colonies

Journal of Vector Ecology, 2011
Sand flies used to have a reputation for being difficult and labour-intensive to breed. Here we summarize our experience with establishment and maintenance of sand fly colonies and their use for infective experiments: techniques for collection and handling wild-caught females, rearing larvae and adults and experimental infections of sand flies by ...

THE SAND-FLY AND PELLAGRA

Journal of the American Medical Association, 1912
For more than 200 years the etiology of pellagra has been a subject of serious inquiry. This problem, formerly an Old World question, now concerns us, and it still awaits solution. Though the disease is positively known to have existed in this country for less than thirty years, it is now found in almost one-half the states of the Union, becoming in ...

Permeability of Sand-bentonite and Sand-fly Ash Mixtures

Asian Journal of Water, Environment and Pollution, 2014
Laboratory hydraulic conductivity (HC) tests have been conducted on mixtures of fine sand with bentonite and fly ash with four fluids with different pH and metal concentrations with a view to assess their suitability for liner constructions for waste containment facilities.

The biological function of sand fly and Leishmania glycosidases

Medical Microbiology and Immunology, 2001
This is a summary of the recent work on some glycosidases of sand flies and their Leishmania parasites. Glycosidases catalyze the hydrolysis of complex sugar subunits of polysaccharides into simple sugars. Leishmania major parasites secrete chitinase and N-acetylglucosaminase, which enables them to survive in the gut of the sand fly and are important ...

Sand Fly Fever-Naples Infection in Egypt

The American Journal of Tropical Medicine and Hygiene, 1987
Two Egyptian male patients with sand fly fever-Naples virus infection are presented. The virus was isolated from one patient while both patients had diagnostic rises in indirect fluorescent antibody titers to the virus. The viral isolate, SFN 85055, grows to much higher titers and plaques more efficiently than the prototype sand fly fever-Naples virus ...
