Association of Lutzomyia columbiana (Diptera: Psychodidae) with a Leishmaniasis Focus in Colombia Due to Species of the Leishmania mexicana Complex [PDF]

Memorias do Instituto Oswaldo Cruz, 1999
In Colombia, Leishmania mexicana has a scattered geographical distribution and no sand fly vectors have been associated with its transmission. During the present study, the anthropophilic sand fly Lutzomyia columbiana was found to be the only species ...

Experimental investigations for assessing the influence of fly ash on the flow through porous media in Darcy regime

Water Science and Technology, 2021
Hydraulic conductivity plays a vital role in the studies encompassing explorations on flow and porous media. The study investigates the compaction characteristics of a river sand (Beas, Sutlej, and Ghaggar rivers) and fly ash mix in different proportions

Human occupation, not forest structure, determines sand fly abundance in the Amazon. [PDF]

Parasit Vectors
Background Across Amazonian deforestation frontiers, phlebotomine sand flies transmit Leishmania spp., the causative agents of American cutaneous leishmaniasis (ACL). Landscape modification can alter vector ecology and transmission risk, yet the relative

Leishmania major-Infected Phlebotomus duboscqi Sand Fly Bites Enhance Mast Cell Degranulation

Pathogens, 2023
Leishmania parasites infect mammalian hosts through the bites of sand fly vectors. The response by mast cells (MC) to the parasite and vector-derived factors, delivered by sand fly bites, has not been characterized.

The role of dermis resident macrophages and their interaction with neutrophils in the early establishment of Leishmania major infection transmitted by sand fly bite

bioRxiv, 2020
There is substantial experimental evidence to indicate that Leishmania infections that are transmitted naturally by the bites of infected sand flies differ in fundamental ways from the inflammatory and immune reactions initiated by needle inocula.

Ecological and control techniques for sand flies (Diptera: Psychodidae) associated with rodent reservoirs of leishmaniasis. [PDF]

PLoS Neglected Tropical Diseases, 2013
BACKGROUND: Leishmaniasis remains a global health problem because of the substantial holes that remain in our understanding of sand fly ecology and the failure of traditional vector control methods.
