Molecular detection and characterization of cpb2 gene in Clostridium perfringens isolates from healthy and diseased chickens
Provedor de dados: 80
Autores: Tolooe,A; Shojadoost,B; Peighambari,SM.
Clostridium perfringens is an important pathogen in both human and veterinary medicine. Necrotic enteritis (NE) is the most clinically dramatic bacterial enteric disease of poultry induced by C. perfringens. The pathogenicity of this bacterium is associated with the production of extracellular toxins produced by some of its strains, such as beta2 toxin. The exact role of beta2 toxin in NE pathogenesis is still controversial. In the present study, C. perfringens isolates from healthy and diseased poultry flocks from different parts of Iran were analyzed by PCR assay to determine the presence of all variants of the beta2 toxin gene (cpb2). The products of two positive cpb2 PCR reactions were sequenced, compared to each other and to the cpb2 sequences...

Dasypoda intermedia spec. nov. from Iran is described. Its description fills a gap of our knowledge of the East Mediterranean fauna of the genus Dasypoda. The West Mediterranean Dasypoda species are well known but the eastern species lack convincing records. Moreover, D. intermedia spec. nov. is a very interesting species from a phylogenetic point of view. It shares some characters common to subgenera Dasypoda s. str. and Megadasypoda Michez, 2004, which provide further evidence for the close relationship of both subgenera.

Autores: Moshrefi Zarandi,D; Aminaee,MM; Rezaee,S; Sharzei,A.
Lemon verbena (Lippia citriodora) is a medicinal plant from the Verbenacea family. Its plantation and medicinal use in Iran has risen greatly in recent years. Crown and root rot symptoms were observed on this plant in some farms and greenhouses of Kerman province during November 2012. The infected plants were taken to the laboratory. Then, samples of infected root tissues were removed and were surface sterilized with 0.5% sodium hypochlorite and cultured onto CMA-PARPH medium. Based on morphological features, the isolated fungus was identified as Phytophthora cactorum. Pathogenicity test was performed using inoculated wheat seeds. To our knowledge this is the first report of Phytophthora cactorum on lemon verbena in Iran.

Effectiveness of Government Protective Policies on Rice Production in Iran
Provedor de dados: 31
Autores: Najafi,   Bahaeddin; Bakhshoodeh,   Mohamad.
To evaluate the government intervention effects on growth of rice production in Iran, the nominal protective rate was calculated and a Nerlove supply model was applied to a time series of 1983-1998. The results showed that in the majority of these years, producers has not been supported and therefore, redirecting the rice market is recommended. In order to get more efficient approach than the government intervention, diminishing the share of the government in the market and strengthening the private sector may be listed on the top of a list that could be regarded as a plan for making rice production profitable.

Asymmetric Price Transmission and Non-linear Adjustment in the Iranian Mutton Market
Provedor de dados: 31
Autores: Falsafian,   Azadeh; Yazdani,   Saeed; Moghaddasi,   Reza.
This paper analyses the asymmetric price transmission and non-linear adjustment at the farm and retail levels in the Iran’s mutton market. We applied a multivariate threshold error correction mechanism for monthly price data. We tested the non-linear adjustment using sup-LR, sup-LM and sup-Wald tests. The results confirm the presence of non-linear cointegration relationship between the retail and farm prices. In short-run, the price transmission behavior reveals that reactions of both the retail and farm prices to positive and negative deviations from the long-run price spread are asymmetric. More specially, the retailers show more strong responses to the both positive and negative shocks imposed to the farmers.

Economic Efficiency of Smallholder Intensive Dairy Farms in Iran: Adjusted for Market Distortion
Provedor de dados: 31
Autores: Bakhshoodeh,   Mohamad; Shahnoushi,   Naser.
The dairy farmers in Iran are faced with milk price distortion due to the market imperfection. To measure an unbiased farm-specific efficiency, prices should be adjusted in an imperfect market. To examine this issue, a shadow-price profit frontier was applied to a sample of 860 Iranian small intensive dairy farms surveyed in 2005-06 in order to calculate profit efficiency of individual dairy farmers. This adjusted measure was then compared with that of unadjusted measure that assumes undistorted market. A multiple general linear model (GLM) technique was applied to the data to examine the multiple effects of pure-bred animals, and the used farm capacity on profit efficiency indices. The mean value of adjusted profit efficiency was 0.40, significantly...

This study examines the relationship between food prices and monetary policy variables, using a Vector Error Correction Model (VECM) approach applied to annual data from 1976 to 2006. Results indicate that food prices in Iran have a long-run and short-run equilibrium granger causality relationship with money supply. More specifically, monetary policy reforms are shown to have a significant impact on food prices and domestic agricultural production. These policies influence consumption patterns and have serious implications for poverty reduction, food security issues, and agricultural growth in Iran.

Analyzing the Impact of Structural Change in Iranian Agricultural Credit System
Provedor de dados: 31
Autores: Yazdani,   Saeed.
Replacement of the traditional interest based credit system with an Islamic credit system was one of the fundamental changes in Iran since 1979. The Islamic credit system, offers the prospect of risk sharing between the borrower and the lender. Small farmers are likely to be risk averse and they are reluctant to go heavily into debt in order to finance investments in new technology and capital intensive methods of production which they perceive to be risky. Farmer's decision making behaviour with regard to risk under the Islamic and interest based credit systems are explored with the aid of a simple conceptual model. Analysis of attitudinal data suggests that the majority of small farmers prefer credit provided under the Islamic credit system. Farmers'...

It illustrates the endless ingenuity of farmers in their quest for water, how land and water rights have developed, how various legal repertoires may conflict with one another, and how the intervention of the state transformed the wider hydrological cycle of the valley and affected the delicate equilibrium between population and resources that had prevailed until then. The report estimates the costs of accessing one cubic meter from each of these different sources and shows how political interventions or drought mitigation...

Provedor de dados: 31
Autores: Verdinejad,   Fereydoun; Gorji,   Yasaman.
In order to activate the cycle of wealth production, promote social justice and eliminate poverty and inequality, developing countries are currently faced with a multiplicity of structural problems. According to some economic theories, this is mainly due to inefficient or lack of access to financial resources, which has proved a major obstacle in activating the cycle of wealth production in such countries. On this assumption, countries with huge oil reserves including Iran, should not encounter obstacles in terms of creating and accelerating the national cycle of wealth production. However, the fact is almost all major oil-producing countries and the main exporters of petroleum products in the world are dealing with serious structural issues in...

The Relational Ship between Rice Market Liberalization and Food Security in Iran
Provedor de dados: 31
Autores: Mousavi,   S.N.
In an effort to alleviate rice shortages, the Iranian government is attempting to encourage the private sector to become more involved in the rice market and trade of Iran. To this end, the multi rate foreign exchange system, which was adopted for several years mainly to support consumers, is being substituted by a single rate, with which the consumer price of rice is expected to decline, and the producer price to increase towards the world price. In this study, the links between change in rice price on the one hand, and poverty and food insecurity (measured by calorie intake) on the other, are calculated by applying Foster-Greer-Thorbecke (1984) measures to data from a sample of 540 Iranian households. Because of the increase in the real income of...

Seroprevalence survey of H9N2 avian influenza virus in backyard chickens around the Caspian Sea in Iran
Provedor de dados: 89
Autores: Hadipour,MM.
Since 1998, an epidemic of avian influenza occurred in the Iranian poultry industry. The identified agent presented low pathogenicity, and was subtyped as an H9N2 avian influenza virus. Backyard chickens can play an important role in the epidemiology of H9N2 avian influenza virus infection. Close contact of backyard chickens with migratory birds, especially with aquatic birds, as well as neighboring poultry farms, may pose the risk of transmitting avian influenza virus, but little is known about the disease status of backyard poultry. A H9N2 avian influenza virus seroprevalence survey was carried out in 700 backyard chickens from villages around the Caspian Sea, Northern Iran, using the hemagglutination-inhibition (HI) test. The studied backyard chickens...

Several enzymes that contribute to immune system responses require zinc and copper as trace elements for their activity. We examined zinc and copper levels in two susceptible Balb/c mouse lines and resistant C57bl/6 mice infected with Leishmania major MRHO/IR/75/ER, a prevalent strain that causes cutaneous leishmaniasis in Iran. Serum Zn and Cu were determined by flame atomic absorption spectrophotometry. Higher Cu levels were found in infected C57bl/6 mice and higher Zn levels were found in infected Balb/c mice. Also, Cu/Zn ratios were increased in both the Balb/c and the C57bl/6 mice. We conclude that concentrations of essential trace elements vary during cutaneous leishmaniasis infection and that this variation is associated with...
