The causative agent of visceral leishmaniasis (VL) in Iran is Leishmania infantum (L. infantum) (... more The causative agent of visceral leishmaniasis (VL) in Iran is Leishmania infantum (L. infantum) (Mediterranean type) and its major reservoir host is the dog. 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. infantum. 61 blood samples from VL patients referred to Shiraz hospitals and 49 blood samples from control group were collected. Native strain of the parasite isolated from a VL patient from the region was cultured and characterized. Antigens from this L. infantum parasite were used in ELISA and IFA system. Anti-Leishmania antibody was detected in 43 (70.5%), 49 (80.3%) and 51(83.6%) cases using DAT, IFA and ELISA, respectively. Based on these results, sensitivity and specificity of DAT was found to be 70.5% and 100%, respectively. Sensitivities of IFA and ELISA in diagnosis of VL were 80.3% and 83.6% and their specifi...

Molecular techniques including PCR, which has proved more sensitive and specific than microscopic examination methods, help to detect infection in low levels of parasitemia and mixed infections. Main our objectives were setting up nested PCR for detection of malaria and evaluating PCR based on plasmodia DNA from blood smears in Fars province, the comparison of this method with traditional microscopy and also evaluate the data in comparison with its neighboring province, Hormozgan. A total of 149 malaria positive samples including 116, 19, and 14 samples from Shiraz, Jask, and Lengeh ports were utilized in this study, respectively. Blood slides were prepared for microscopic observation. DNA from thin smears was extracted and nested PCR was analyzed using rPLU5 and rPLU6 for genus specification, rFAL1, rFAL2, and rVIV1, rVIV2 for P. falciparum and P. vivax detection, respectively. T...

Infections of human are common and are usually asymptomatic. The infection may be serious if is transmitted to the fetus during pregnancy. Prophylactic measures, early detection of the infection and treatment can avoid congenital toxoplasmosis and many long term effects. Objective: Seroepidemiological study in young girls is useful to determine the prevalence of infection and to design prevention policies for them after ...

Thus, the aim of this study is the application of different enzymatic systems for discrimination species and strains visceral leishmaniasis agent. Materials and methods: In this experimental study, reference strains of Leishmania infatum, Leishmania major, Leishmania tropica in addition, the leishmania parasites isolated from bone marrow of subjects and ...
