AIM The spatial structure of a population can strongly influence the dynamics of infectious diseases, yet rarely is the underlying structure quantified. A case in point is plague, an infectious zoonotic disease caused by the bacterium Yersinia pestis. Plague dynamics within the Central Asian desert plague focus have been extensively modelled in recent years, but always with strong uniformity as...

background: zoonotic cutaneous leishmaniasis (zcl) is an expanding disease and public health problem in iran. in the current study, natural leishmania infection rate and seasonal fluctuation of the infection in rhombomys opimus population of a hyperendemic focus of zcl in iran was investigated. methods:   the study was conducted from october 2006 to october 2008 in esfahan province, central par...

b a ckground: zoonotic cutaneous leishmaniasis is a growing health problem in many rural areas of iran. rhombo mys opimus , the great gerbil, is the main animal reservoir of zcl in the northeast and central part of iran. the aim of the current study was to evaluate the rodenticidal effect of coumavec® (a mixture of coumatetralyl 0.5% and etofenprox 0.5%) on r. opimus under laboratory condition....

background: the aim of the study was to determine the helminthic species occurring in great gerbil rhombomys opimus collected from maraveh tappeh, golestan province, northeast iran. methods : during 2010-2011, a total of 77 r. opimus were captured from rural areas of maraveh tap-peh, golestan province, using sherman live traps and examined for infectivity with any larva or adult stages of helmi...

The study is the first attempt to generalize data on burrow biocenoses of great gerbil (Rhombomys opimus (Lichtenstein, 1823)) in region persistent plague epizootics lowland part Karakum Desert (Southern Turkmenistan). material was collected May, November, and December 1987–1988 using trapping cylinders residential non-residential colonies gerbil. Coleoptera made up about 40% species compositio...

Background: Zoonotic cutaneous leishmaniasis (ZCL) due to Leishmania major is increasing in many parts of Iran. This disease originally is a disease found in gerbils. Leishmania parasites are transmitted by sandflies that live and breed in gerbil burrows. Nested PCR amplified Leishmania ITS1-5.8S rRNA gene in both main reservoir host “Rhombomys opimus” and in the “Phlebotomus papatasi” main vec...

during our study (summer of 1994) twenty two tatera indica were collected and two out of them (9.09%) were naturally infected with amastigote. parasites were cultured in nnn+lit medium and isolated promastigotes were sent to the medical university of montpellier in france for identification. the result of isoenzyme showed, the parasite was leishmania major zymodem mon 26-(=lon 1), therefore tat...
