RESUMO

Malaria is one of the most important infectious diseases worldwide and also in Iran. Reports announced by Controlling Diseases Center [CDC] prove the presence of two species including Plasmodium vivax and Plasmodium falciparum in this province. P. falciparum cases diagnosis in purpose of true treatment and following up patients is necessary. This study is intending to extract DNA from negative microscopic smears using the newly invented method by research group and afterwards to evaluate negative malaria Giemsa-stained smears using nested polymerase chain reaction. Aiming to diagnose malaria, nested PCR amplification was accomplished using DNA extracted from fixed negatively diagnosed microscopic smears and Giemsa-stained. The extracted DNA was used as a pattern to amplify the specific sequence of P. falciparum and P. vivax using the small subunit of ribosomal RNA [18ssrRNA]. This retrospective study was implemented on 500 malaria negative microscopic smears storing from 6 months to 1 year. By accomplishing PCR amplification on 500 microscopic smears, 54 [10.8%] malaria positive samples were diagnosed which were incorrectly diagnosed to be negative previously. Of all specimens revealed to be positive, 34 [6.8%] cases were P. vivax while 20 [4%] cases were P. falciparum. This study reveals the priority of nested-PCR method to microscopic examination method and the possibility of using old microscopic smears in epidemiologic and retrospective studies clearly

RESUMO

Zahedan is a tropical region in southeast of Iran. Due to importance of congenital Toxoplasmosis and absence of study evidences in this field in Zahedan, this research was accomplished. 221 serum samples were collected from pregnant women referring to reference laboratory of Zahedan. The IgG and IgM antibody levels against were examined using ELISA method. 30.8% cases out of all samples were IgG positive and in 1.4% cases IgG and IgM were both positive for toxoplasmosis. 69.2% of pregnant women were serologically negative against toxoplasmosis; therefore hygiene education to eliminate risk factors especially during pregnancy period seems to be imperative
