Visceral leishmaniasis (VL) is a chronic and fatal disease caused by Leishmania infantum in Brazil. Leukocyte recruitment to infected tissue is a crucial event for the control of infections such as VL. Among inflammatory cells, neutrophils are recruited to the site of Leishmania infection, and these cells may control parasite replication through oxidative or non-oxidative mechanisms. The recrui...
OBJECTIVES Apoptosis is the process of programmed cell death (PCD) that occurs in both animal and plant cells. Protozoan parasites possess metacaspase and these caspase-related proteases could be involved in the PCD pathways in these organisms. Therefore we analyzed the activities of metacaspase and PARP genes in Leishmania infantum (MCAN/IR/96/LON49) treated with miltefosine. MATERIALS AND M...
Diseases such as leishmaniases are important causes of morbidity and mortality in Brazil, and their diagnoses need to be improved. The use of monoclonal antibodies has ensured high specificity to immunodiagnosis. The development of an immunosensor, coupling a monoclonal antibody to a bioelectronic device capable of quickly detecting Leishmania sp. antigens both qualitatively and quantitatively,...
Leishmaniasis represents a serious threat to the health as one of the most important neglected tropical diseases as designated by the World Health Organization. The disease is endemic in 82 countries, among them Tunisia is an indigenous area for cutaneous Leishmaniasis. In a previous work, two tritepenic acids namely oleanolic and maslinic acids have been isolated from olive leaf extract. In th...
BACKGROUND The causative agent of visceral leishmaniasis (VL) in Iran is Leishmania infantum (L. infantum) (Mediterranean type) and its major reservoir host is the dog. OBJECTIVE To compare the serological methods including direct agglutination test (DAT), indirect immunofluorescent-antibody test (IFA) and enzyme-linked immunosorbent assay (ELISA) for serodiagnosis of endemic strain of L. inf...
Old World cutaneous leishmaniasis is a widespread and potentially disfiguring protozoal infection that is endemic in the Mediterranean basin, Africa, and parts of Asia. Human infection is caused by several species of Leishmania parasites, such as Leishmania infantum. Available systemic and topical treatments vary in efficacy and are often unjustified due to their toxicity. We report on a case t...
BACKGROUND Visceral leishmaniasis due to Leishmania infantum is currently spreading into new foci across Europe. Leishmania infantum transmission in the Old World was reported to be strongly associated with a few specific environments. Environmental changes due to global warming or human activity were therefore incriminated in the spread of the disease. However, comprehensive studies were lacki...
BACKGROUND Visceral leishmaniasis is an important tropical disease, and Leishmania infantum chagasi (synonym of Leishmania infantum) is the main pathogenic agent of visceral leishmaniasis in the New World. Recently, ecto-nucleoside triphosphate diphosphohydrolases (E-NTPDases) were identified as enablers of infection and virulence factors in many pathogens. Two putative E-NTPDases (∼70 kDa and ...
objective(s) leishmania can lead to a broad spectrum of diseases, collectively known as leishmaniasis. the a2 gene/ protein family could be one of the most eligible candidate factors of virulence in visceral leishmaniasis (vl). the previous results confirmed that in leishmania infantum, several a2 proteins are abundantly expressed by the amastigote, but not the promastigote stage. as there are ...
To determine the role that Leishmania infantum/human immunodeficiency virus (HIV) coinfected patients could play in the epidemiology of visceral leishmaniasis (VL), we applied direct xenodiagnosis of VL in this study to test the infectivity of six coinfected patients to colonized Phlebotomus perniciosus. All patients proved to be infective for the sand flies. The infectivity of patients who had...
