Leishmania infantum is the causative agent of infantile visceral leishmaniasis (IVL) in the Mediterranean Basin and, based on isoenzyme typing of the parasite isolated from dogs; this parasite was considered to predominate in the all foci of IVL in Iran. However, based on PCR detection and sequencing of parasite Cysteine Protease B (CPB), only one out of(More)
BACKGROUND Using botanical insecticides as an alternative biocontrol technique for vector control is considered by some scientists. MATERIALS AND METHODS Chemical composition of the essential oil was analyzed using gas chromatography-mass spectrometry (GC-MS). In addition, the mosquito larvicidal activity of leaf essential oil of Cupressus arizonica was(More)
Discrimination of Leishmania infantum and L. donovani, the members of the L. (L.) donovani complex, is important for diagnosis and epidemiological studies of visceral leishmaniasis (VL). We have developed two molecular tools including a restriction fragment length polymorphisms of amplified DNA (PCR-RFLP) and a PCR that are capable to discriminate L.(More)
BACKGROUND According to the national strategy plan on monitoring of insecticides resistance, this study was carried out to determine the base line susceptibility of the Culicidae mosquitoes to the WHO-recommended insecticides in an endemic focus of malaria in southeastern Iran. METHODS Larval collection was carried out by dipping method and adult(More)
BACKGROUND Crimean-Congo Hemorrhagic Fever (CCHF) is a feverous and hemorrhagic disease endemic in some parts of Iran and caused by an arbovirus related to Bunyaviridae family and Nairovirusgenus. The main virus reservoir in the nature is ticks, however small vertebrates and a wide range of domestic and wild animals are regarded as reservoir hosts. This(More)
BACKGROUND Application of plant derivatives have been suggested as alternative sources for mosquito control. METHODS The root essential oil and methanol extract of Cionura erecta (L.) Griseb was tested under laboratory conditions for larvicidal and skin repelleny activities against Anopheles stephensi. The chemical compositions of essential oils were(More)
BACKGROUND Bait-trapping appears to be a generally useful method of studying fly populations. The aim of this study was to construct a new adult flytrap by some modifications in former versions and to evaluate its applicability in a subtropical zone in southern Iran. METHODS The traps were constructed with modification by adding some equipment to a(More)
BACKGROUND Recently, essential oils and extracts derived from plants have received much interest as potential bio-active agents against mosquito vectors. METHODS The essential oils extract from fresh peel of ripe fruit of Citrus aurantium and Citrus paradisi were tested against mosquito vector Anopheles stephensi (Diptera: Culicidae) under laboratory(More)
BACKGROUND Wolbachia are common intracellular bacteria that infect different groups of arthropods including mosquitoes. These bacteria modify host biology and may induce feminization, parthenogenesis, male killing and cytoplasmic incompatibility (CI). Recently Wolbachia is being nominated as a bio-agent and paratransgenic candidate to control mosquito borne(More)
