1. Lower galactosylation levels of the Lipophosphoglycan from Leishmania (Leishmania) major-like strains affect interaction with Phlebotomus papatasi and Lutzomyia longipalpis
BACKGROUND Leishmania major is an Old World species causing cutaneous leishmaniasis and is transmitted by Phlebotomus papatasi and Phlebotomus duboscqi. In Brazil, two isolates from patients who never left the country were characterised as L. major-like (BH49 and BH121). Using molecular techniques, these isolates were indistinguishable from the L. major ref

2. Experimental infection of Phlebotomus perniciosus by bioluminescent Leishmania infantum using murine model and artificial feeder
Leishmaniasis is a vector-borne disease that is transmitted by sandflies and caused by obligate intracellular protozoa of the genus Leishmania. In the present study, we carried out a screening on the experimental infection of Phlebotomus pernioucus by bioluminescent Leishmania infantum using murine model and artificial feeder. We developed a real-time polyme

3. Vias de transmissão da leishmaniose visceral em mamíferos
A leishmaniose visceral (LV) é uma doença crônica causada pelo protozoário
Leishmania infantum. Os principais sítios de localização do parasito nos animais acometidos pela LV foram órgãos linfoides primários, secundários e tegumento. Contudo, existem relatos da detecção do parasito em órgãos do sistema genital masculino e femininCienc. Rural. Publicado em: 30/06/2015

4. Status taxonômico de Phlebotomus oliverioi (Diptera, Psychodidae) e designação de lectótipo para Psathyromyia brasiliensis
Phlebotomus oliverioi Barretto & Coutinho, 1941 foi originalmente descrita baseada em um único macho e desde então tem sido considerada sinônimo-júnior de Psathyromyia brasiliensis (Costa Lima, 1932). O estudo do holótipo de Ph. oliverioi nos levou a concluir que a cabeça deste espécime pertence ao gênero Psychodopygus e as asas, tórax e abdômen pe

5. Effect of mouse antisera targeting the Phlebotomus papatasi midgut chitinase PpChit1 on sandfly physiology and fitness
In sandflies, the absence of the peritrophic matrix (PM) affects the rate of blood digestion. Also, the kinetics of PM secretion varies according to species. We previously characterised PpChit1, a midgut-specific chitinase secreted in Phlebotomus papatasi (PPIS) that is involved in the maturation of the PM and showed that antibodies against PpChit1 reduce th

6. Kidney involvement in leishmaniasis—a review
Leishmaniasis is an infectious disease caused by protozoa of the genus Leishmania transmitted by insects of the genus Lutzomyia sp. or Phlebotomus sp. The main syndromes are cutaneous leishmaniasis, mucocutaneous leishmaniasis, visceral leishmaniasis (kala-azar) and post-kala-azar dermal leishmaniasis. This article reviews kidney involvement in cutaneous and

7. Limits of a rapid identification of common Mediterranean sandflies using polymerase chain reaction-restriction fragment length polymorphism
A total of 131 phlebotomine Algerian sandflies have been processed in the present study. They belong to the species Phlebotomus bergeroti, Phlebotomus alexandri, Phlebotomus sergenti, Phlebotomus chabaudi, Phlebotomus riouxi, Phlebotomus perniciosus, Phlebotomus longicuspis, Phlebotomus perfiliewi, Phlebotomus ariasi, Phlebotomus chadlii, Sergentomyia fallax

8. Ecology of cutaneous leishmaniasis in Sinai: linking parasites, vectors and hosts
Cutaneous leishmaniasis (CL) is a neglected clinical form of public health importance that is quite prevalent in the northern and eastern parts of Egypt. A comprehensive study over seven years (January 2005-December 2011) was conducted to track CL transmission with respect to both sandfly vectors and animal reservoirs. The study identified six sandfly specie

9. Leishmaniasis transmission: distribution and coarse-resolution ecology of two vectors and two parasites in Egypt
Introduction: In past decades, leishmaniasis burden has been low across Egypt; however, changing environment and land use has placed several parts of the country at risk. As a consequence, leishmaniasis has become a particularly difficult health problem, both for local inhabitants and for multinational military personnel. Methods: To evaluate coarse-resol

10. Phlebotomus (Legeromyia) multihamatus subg. nov., sp. nov. from Gabon (Diptera: Psychodidae)
During a research project aimed at the study of the Culicinae fauna of Gabon and carried out in the National Park of La Lopé, we captured an unknown sandfly male specimen (genus Phlebotomus) by CDC miniature light trap belonging to a new species for Science. Furthermore, the originality of his genitalia does not allow us to include this species in one of th

11. Oviposition behaviour of Phlebotomus argentipes - A laboratory-based study
The breeding habitat of sandflies is a little studied and poorly understood phenomenon. More importantly, oviposition behaviour is a largely neglected aspect of sandfly biology and this knowledge gap further undermines our understanding of the biology of sandflies. Pheromones released by the eggs play an important role in identifying good sites for ovipositi

12. Kazal-type serine proteinase inhibitors in the midgut of Phlebotomus papatasi
Sandflies (Diptera: Psychodidae) are important disease vectors of parasites of the genus Leishmania, as well as bacteria and viruses. Following studies of the midgut transcriptome of Phlebotomus papatasi, the principal vector of Leishmania major, two non-classical Kazal-type serine proteinase inhibitors were identified (PpKzl1 and PpKzl2). Analyses of expres
