Sand fly Phlebotomus chinensis is a primary vector of transmission of visceral leishmaniasis in China. The sand flies have adapted to various ecological niches in distinct ecosystems. Characterization of the microbial structure and function will greatly facilitate the understanding of the sand fly ecology, which would provide critical information for developing intervention strategy for sand fl...

BACKGROUND Cutaneous leishmaniasis (CL) is an important health problem in the New World affecting civilian and military populations that are frequently exposed in endemic settings. The Peruvian region of Madre de Dios located near the border with Brazil is one of the most endemic CL regions in South America with more than 4,451 reported cases between 2010 and 2015 according to the Peruvian epid...

The vector-borne disease leishmaniasis, caused by Leishmania species protozoa, is transmitted to humans by phlebotomine sand flies. Development of Leishmania to infective metacyclic promastigotes in the insect gut, a process termed metacyclogenesis, is an essential prerequisite for transmission. Based on the hypothesis that vector gut microbiota influence the development of virulent parasites, ...

BACKGROUND Phlebotomine sand flies are known to transmit Leishmania parasites, bacteria and viruses that affect humans and animals in many countries worldwide. Precise sand fly identification is essential to prevent phlebotomine-borne diseases. Over the past two decades, progress in matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has emerged as an acc...

BACKGROUND Nearly 1300 cases of leishmaniasis have been identified in American military personnel deployed to Iraq and Afghanistan. The symptoms of this disease can range from a mild, self-limiting cutaneous infection to a deadly visceral infection and are not prevented by chemoprophylaxis or immunization. Effective treatments, however, are available. The disease-causing parasite is spread thro...

little is known about sand fly fever with manifestations such as severe fever, headache and photophobia at the frontiers before the imposed war iraq against iran (1980-1988). in this article the seroepidemiological study of sand fly fever in different western provinces of iran were investigated during imposed war iraq against iran from march 1987 to march 1988. seroepidemiological studies were ...

establishment of a vector-borne disease. For example, tick-derived saliva factors appear to inhibit inflammatory cytokine secretion thus preventing efficient immune responses against tick-borne Rickettsia (4); a defined molecule in the saliva of the Aedes aegypti mosquito (SAAG-4) has the potential to alter the Th-profile of the bite-induced immune response likely rendering the host unable to e...

Sand fly and Leishmania are one of the best studied vector-parasite models. Much is known about the development of these parasites within the sand fly, and how transmission to a suitable vertebrate host takes place. Various molecules secreted by the vector assist the establishment of the infection in a vertebrate, and changes to the vector are promoted by the parasites in order to facilitate or...

Cutaneous leishmaniasis is a zoonotic, vector-borne disease causing a major health problem in several countries. No vaccine is available and there are limitations associated with the current therapeutic regimens. Immune responses to sand fly saliva have been shown to protect against Leishmania infection. A cellular immune response to PpSP15, a protein from the sand fly Phlebotomus papatasi, was...

Background and Objective: Leishmaniasis is one of the most important vector-borne zoonosis that transmits to human by sand fly species. The current study was carried out to identify sand fly species in Zirkooh, Khorasan-e-Jonobi Province. It was also aimed to determine Leishmania species in infected sand flies by RFLP-PCR method. Materials and methods:Sand fly specimens were collected by usi...
