A significant phase of global warming appeared during the Llandovery and productive Silurian hot shale was preserved all over the world.The lower Silurian shale is the main effective source rock for most of the Paleozoic hydrocarbon in iran and the Arabian platform.Silurian hot shales have become prospective resources for new energy such as shale gas.The regional distribution and shale gas potential of the lower Silurian hot shale in Southern Iran and the Arabian plate are determined using outcrops and exploration well samples data from previous studies.The studied area has a high organic content(on average more than 2%),maximum burial depth is 5300 m,shale thickness of 30-200 m,organic matter maturities(most comparable),clay minerals content ranging from 20%to 57%,quartz content ranges from 20%to 49%,feldspar content ranges from 10%to 15%and calcite content ranges from 1.48%to 5%which all favor shale gas generation and accumulation.We concluded that Southern Iran and east-central Saudi Arabia are two of the most sustainable and favorable locations for shale gas exploration and production for lower Silurian hot shale after assessing all of the key characteristics.

Objective: To update current situation of the cutaneous leishmaniasis(CL) in Kazerun County,southwest of iran and to analyze the epidemiological aspects of the disease during 2005-2015,Methods: Data on CL were obtained from the Health Center of Kazerun County,and then were analyzed and mapped using SPSS and Arc GIS 10.3,Results: A total of 700 cases of CL were recorded during the study period with an overall decreasing trend from 2005 to 2015,More than 60% of the patients were inhabitants of rural areas and males were infected more than females,Although there was not a significant difference between gender,job categories,residence and CL infection(P>0.05),age groups were significantly different(P0.05),Most of the acute lesions were found to be present on the hand,leg and face,respectively,The average CL incidence in the study area was calculated as 24.9/100 000 population,A hot spot for the disease was found in southern part of the area(P<0.05),Conclusions: This study revealed that CL is present in Kazerun country,Thus,effective monitoring and sustained suveillance system is crucial in counteracting the disease,and if possible,to eliminate it.

Small Indian mongoose(Herpestes auropunctatus)in iran:first evidence for the infection with Spirura sp.(Nematoda:Spiruridae)

Journal of Coastal Life Medicine 2014年第11期2卷 899-902页

作者： Ehsan Rakhshandehroo Hassan Sharifiyazdi Hossein Shayegh Amin Ahmadi Department of Pathobiology School of Veterinary MedicinShiraz UniversityShirazIran Department of Clinical Studies School of Veterinary MedicinShiraz UniversityShirazIran

Objective:To investigate the infection with gastrointestinal helminthes in small Indian mongooses(Herpestes auropunctatus)and its epidemiologic aspects in iran.Methods:During June 2012 to July 2013,a total of 13 small Indian mongooses were caught using live trap boxes in an area located near Shiraz,southern of iran.Captured animals were euthanized,eviscerated and parts of the alimentary tract were inspected.Two mongooses showed a nematode attached to the mucosa of the stomach.Results:According to the main morphological characteristics,the specimens belonged to the genus Spirura(Blanchard 1849).This study represents the first evidences of the infection withSpirura sp.in Herpestes auropunctatus in the world.Conclusions:Because the animal can invade and appear in the habitat of the other animal populations including omnivores or carnivores,it seems that mongooses in this area could have a high potential for the transmission of the infection with the spirurid nematodes to a large range of animals.Thus,besides the necessity of conducting the controlling programs,autochthonous dogs,cats and rodents should be included in more epidemiological studies in this region.
