Canine visceral leishmaniosis (CVL) causes a dependent-stage alteration in neutrophil oxidative metabolism. When production of reactive oxygen species (ROS) exceeds the antioxidant capacity of neutrophils, apoptosis is triggered, impairing the viability and function of these cells, which can predispose dogs to infection. However, the uremic condition observed in late-stage CVL can also alter th...

Leishmaniasis comprises a group of diseases caused by protozoa of the genus Leishmania and has two basic clinical forms, visceral Leishmaniasis and cutaneous Leishmaniasis. The clinical features of Leishmaniasis depend on the species of Leishmania, the interaction between host and parasite and the immune response. This work focuses on cutaneous leishmaniosis because although it is not a deadly ...

The murine model of leishmaniosis is a prototypic example for the critical role played by T helper cells in immunity to pathogens. Cytokines, such as interleukin-12 and interleukin-4, are the major regulatory factors for differentiation of naive T helper cells into T helper 1 and T helper 2 cells, respectively. T helper 1 cells, which are cellular immune mechanisms involving gamma interferon pr...

An attenuated line of Leishmania infantum (L. infantum H-line) has been established by culturing promastigotes in vitro under gentamicin pressure. A vaccine trial was conducted using 103 naive dogs from a leishmaniosis non-endemic area (55 vaccinated and 48 unvaccinated) brought into an endemic area of southeast Iran. No local and/or general indications of disease were observed in the vaccinate...

The efficacy of Leishmania donovani-derived lipophosphoglycan (LPG) plus Mycobacterium bovis Bacille Calmette-Guerin (BCG) as a vaccine candidate against visceral leishmaniosis in susceptible BALB/c mouse and Syrian golden hamster (Mesocricetus auratus) models was investigated. Following a triple vaccination with a total dose of 150 microl BCG plus 60 microg or 30 microg of LPG for hamsters and...

Modern medicine is increasingly based on the use of new research methods in diagnosing diseases. PCR one such method, which has been widely used parasitology and significantly improved diagnosis visceral leishmaniasis our country. It turned out to be particularly interesting this method case relapses Georgia, because molecular diagnostics allow us determine characteristics parasite, as virulenc...
