Using direct agglutination tests, a survey of visceral leishmaniasis was carried out among children and adults from 13 villages and from nomadic tribes in Bushehr province during 1998-99. Of the 1496 plasma samples, the overall seropositive rate (titres > or = 1:3200) was 3.4%. Almost all cases (94.1%) were in children under 10 years old. Eighteen patients(More)
During the last decade, kala-azar, which used to be a sporadic disease, became endemic in parts of East-Azerbaijan province in north-west Iran. Many of the 1051 cases observed between 1985 and 1990 were in the district of Meshkin-Shahr (800 cases). The diagnosis was based on symptoms and signs of the disease plus a positive serological test (indirect(More)
A total of 1,779 persons from the Caspian Sea area, Iran, were serologically examined by the indirect fluorescent antibody technique for Toxoplasma antibodies. 55.7% were positive with titres of 1:20 or higher. No significant difference was demonstrated between the sexes. The highest antibody level as well as a high geometric mean of reciprocal titres were(More)
BACKGROUND The aim was to evaluate the relapse risk of vivax malaria in patients who received radical treatment in Hormozgan Province, a malarious area located on southeast of Iran. METHODS A total of 95 symptomatic vivax malaria infected patients were enrolled in urban health centers of Bandar-Abbas, Minab, Bandar-Jask and Bashagard districts of(More)
In-vivo and macro and micro in-vitro assessments of the response of P. falciparum to chloroquine and mefloquine were carried out in the malarious areas of Bandar-Abbas and Minab, Hormozgan Province, southern Iran, during 1986-1987. The susceptibility tests indicated a considerable resistance of P. falciparum to chloroquine in Bandar-Abbas but almost(More)
ELISA AND IFAT have been applied to the sero-diagnosis of cutaneous and visceral leishmaniasis and the levels of leishmanial antibody detected by Leishmania donovani antigens in both tests have been compared. From the results it appears that ELISA is a little more sensitive than IFAT, but IFAT seems to be more specific in detecting leishmanial antibodies.(More)
The microplate method of an ELISA was modified for identification of human blood meals from 5,325 engorged mosquitoes belonging to 12 species of Anopheles captured in 19 provinces of Iran. Four hundred and four (7.5%) specimens reacted with the ELISA anti-human alkaline phosphatase conjugate. The human blood index in nine species of Anopheles varied from(More)
Studies of drug resistance of Plasmodium falciparum cases from SE Iran were carried out in vivo and in vitro during 1990-91. In a study of 26 chloroquine-resistant infections, using amodiaquine (25 mg kg-1 over 3 days), followed by two-thirds of the standard dose of sulphadoxine-pyrimethamine, six cases were resistant at the RI(3) and RII(3) levels. An(More)
In Iran, microscopic examination of skin scrapings from 2202 individuals with clinically diagnosed cutaneous leishmaniasis (CL) lesions revealed the presence of amastigotes in 1123 cases (51.0%). Bacteriological examinations of the lesions indicated that 788 individuals (35.7%) were also infected with one or more pathogenic bacteria, including(More)
In the IFA serological surveys of malaria carried out in north, north-west and south-west parts of Iran during 1975-1982 altogether 9,132 subjects were studied for malaria antibodies and parasitaemia. Serological data indicated probable malaria transmission in a consolidation area where the autochthonous cases of malaria were reported a year after this(More)
