Co-inoculation of sandfly saliva and parasites led to disease exacerbation in several studies nolvadex 10 mg with visa menstruation through history, which seems to be related with the modulation of the immune system to favor parasite survival and replication (Kamhawi buy cheap nolvadex 10 mg online women's health center pearland, 2000; Rohousova and Volf, 2006). By contrast, the bites of uninfected sand flies or the vaccination with salivary gland extracts induce T cell mediated protection against an experimental challenge and disclose its potential for vaccination (Belkaid et al. Furthermore, in infected humans, anti-saliva antibodies are detected (Gomes et al. Visceral leishmaniasis can be induced through blood containing amastigotes (shared needles, transfusion, transplacental spread) or organ transplantation (Morillas- Marquez et al. The several Leishmania species that cause disease in humans have a zoonotic transmission, with the exception of L. However, even for these species, some animal reservoirs in endemic areas have recently been identified (Dereure et al. Furthermore, the different Leishmania species do not seem to exhibit reservoir strain or specie specificity, unlike what happens with the sandfly. Indeed, certain Leishmania species are maintained by several hosts, and several Leishmania species may be found in the same host (Saliba et al. This disease is prevalent in the Central and South America, Mediterranean basin and Asia. Dogs are the main domestic reservoirs while jackals, foxes and wolves are the sylvatic ones (for review see Gramiccia and Gradoni, 2005). However, unusual Leishmania animal hosts such as cats and equines have recently been identified in those endemic areas (for review see Mancianti, 2004). The role of cats is still under debate, but they seem to be secondary reservoirs, while equines are incidental hosts (Gramiccia and Gradoni, 2005). The large spectrum of clinical manifestations reflects leishmaniasis’ complexity, mainly associated with the number of Leishmania species that cause disease, as well as many sandfly and mammalian species indicated as vectors and reservoirs, respectively. This could indeed be due, in part, to improved diagnostic and case notification, but inadequate vector and reservoir control, increased detection of cutaneous leishmaniasis associated with opportunistic infections (e. Cutaneous leishmaniasis in endemic areas affects mainly children of up to 15 years of age, and the main risk factors besides age are household design and construction materials, and the presence of domestic animals (Reithinger et al. Indeed, several authors refer to them as synonyms, despite the disagreement of others (Shaw, 1994; Lukes et al. Furthermore, they present high parasite loads in organs, low sensitivity to the serological-based diagnostic tests and treatment failure (Murray et al. Therefore, specific and sensitive tests are very important, not only for a prompt and accurate diagnosis but also for a successful treatment and subsequent disease control. Occasionally, the culture of biopsy triturates or aspirates is 15 Chapter I Leishmania spp. Even though it is very specific, the sensitivity of this method is highly variable and depends largely on the number and dispersion of parasites in the biopsy, the technical skills of the personnel, the sampling procedure and the sample origin (Herwalt, 1999). However, spleen aspirates require considerable technical expertise, since life threatening haemorrhages can occur (Kager et al. Furthermore, the possibility of identifying the Leishmania specie and predicting the disease severity and treatment outcome is becoming important in the patients’ clinical management (Murray et al. One is related to the persistence of the anti-Leishmania antibodies for long periods of time after the cure (Hailu, 1990;De Almeida Silva et al. These tests should therefore be used in combination with clinical symptoms for an 16 Chapter I Leishmania spp. The several limitations of the poor Leishmania endemic areas have boosted the development of diagnostic tests that could be used in the field: easy to perform, cheap, reproducible and rapid. Although, improvements concerning the test sensitivity are required (Chappuis et al.
