Objectives: Staphylococcus aureus is one of the most common causes of food poisoning in humans. Various methods including genotyping based on protein A (Spa typing) and PCR-based methods have been used for genetic classification of this bacterium. In the present study, Spa gene tracking was used for genotyping of Staphylococcus aureus isolates.Methods: 100 samples of raw chicken meat were collected from chicken meat supply centers in the market of Chaharmahal and Bakhtiari province. Samples were tested for Staphylococcus aureus bacteria by microbial culture and molecular methods and the presence of Spa gene in strains detected by PCR and enzymatic digestion.Results: Out of the total of  23 isolates of Staphylococcus aureus studied, 6 isolates lacked the Spa gene. In the rest of the isolates, a fragment with a size of about 1100 to 1500 bp was detected, and based on the detected gene fragment, 17 isolates containing the Spa gene were divided into four genotypes I to IV; So that 9 isolates were in SpaI genotype, 3 isolates in SpaII genotype, 3 isolates in SpaIII genotype and 2 isolates in SpaIV genotype.Conclusion: The presence of high genomic diversity in these isolates indicates cross-contamination of contamination and therefore can be prevented from the presence and growth of this bacterium in food by implementing quality control and food safety standards during the production process.  Manuscript profile

Predicting the potential distribution of plants in response to climate change is essential for their conservation and management. Amygdalus scoparia is a wild almond species native to Iran Therefore, this study aimed at predicting the effect of climate change on the geographical distribution of A. scoparia in Chaharmahal and Bakhtiari province in the central Zagros region. In this regard, we used 5 modeling approaches, Generalized Linear Model (GLM), Classification Tree Analysis (CTA), Artificial Neural Network (ANN), Generalized Boosting Method (GBM) and Random Forest (RF) to determine relationships between the occurrence of species and environmental factors under the ensemble framework by using Biomod and R software. The results showed that AUC values greater than 0.9 and functioning of all models been excellent. The mean temperature of the driest quarter and Annual precipitation had the most important role for habitat suitability of this species and (85%) changes in A. scoparia distribution was justified. The results of the model showed that 9%, (148680 ha) of in Chaharmahal and Bakhtiari province for the A. scoparia have had high habitat suitability. Area of suitable habitat was calculated by ArcGIS software on current and future climate conditions. Under RCP4.5 and RCP8.5 climate scenario A. scoparia might lose (Respectively 43% and 59%) of its climatically suitable habitats due to climate change factors, by 2050, while in a number of areas (135% and 140%), the current unsuitable habitats may be converted to suitable. The results of this study can be used in planning, conservation and rehabilitation of A. scoparia. Manuscript profile

Landslides are among the most damaging natural hazards in mountainous regions. In this study, landslide hazard zonation was conducted in the Baba Heydar Watershed using logistic statistical regression to determine landslide hazard areas. First, a landslide inventory map was prepared using aerial photograph interpretation and field surveys. Next, ten landslide conditioning factors including altitude, slope percentage, slope aspect, lithology, distance from faults, streams, villages and roads, land use, and precipitation were chosen as effective factors on landslide occurrence in the study area. Then, a landslide susceptibility map was constructed using a logistic regression statistical model in a geographic information system (GIS). Relative Operating Characteristics (ROC) and Pseudo R2 indices were used for model assessment. Finally, a risk map was created based on a risk equation using a combination of the susceptibility map, elements at risk and vulnerability. Results showed that the logistic regression statistical model provided slightly higher prediction accuracy of landslide susceptibility in the Baba Heydar Watershed with ROC equal to 0.876. The results revealed that about 44% of the watershed area was located in both the high and very high hazard classes. Additionally, 35% of the surveyed watershed was located in the high and very high-risk classes. This information is critical for the risk management, landslide risk and land planning of this mountainous area.. Manuscript profile

Water is the most precious wealth available to mankind; Especially in the dry areas of the country, which covers a huge area of our country. At the national level, a large share of investments is spent on infrastructure and infrastructure and improving the management of water resources and its transmission. These mentioned factors will show the importance of the water sector and economic and social security at the national level. One of the inter-basin water transfer projects that is being studied and implemented is the transfer of water from Beheshtabad to Zayandehroud. Beheshtabad project is the name used to transfer water from Chaharmahal and Bakhtiari provinces to Isfahan, Yazd and Kerman provinces. The purpose of this article is to analyze the situation of inter-basin water transfer in Isfahan, Chaharmahal and Bakhtiari provinces, which has been collected using descriptive-analytical research method and using library resources and internet sites. The results of the findings show that most experts believe that the implementation of this plan has negative consequences on the provinces of origin in particular and on national security in general. Political activism, security challenges (ethnic conflicts), social, economic and environmental tensions resulting from not studying and incorrect feasibility of the plan are among the issues that make the justification of its implementation appear unjustified.

Abstract Earth Plant ecosystem offers different services, given the current conditions Earth and excessive pollution atmosphere, carbon sequestration to soil by plant communities is one of the most important services in long time. The present study was aimed to assess the effect of exclosure on carbon sequestration and soil physical and chemical properties in rangelands  Chaharmahal and Bakhtiari Province. In each region, seven homogenous sites (grazed and non-grazed) were selected in terms of environmental conditions and vegetation and soil sampling were achieved in the each site. The vegetation sampling was done in rangeland with the establishment of transects and install a four-square-meter plots. The soil samples were done to a depth of 30 cm in each plot at the each site. Aerial biomass and litter in each plot were collected and weighed. The results of analysis data showed that the amount aerial biomass, soil carbon, and total carbon sequestration in semi-steppe rangelands with dominated grasses respectively, with 1.9 t/ha, 51.75 t/ha, and 53.02 t/ha were significantly estimated  more than semi steppe shrubland rangeland. The results also showed that the average total carbon sequestration and soil in both study areas in treatment exclosure had a significant difference in grazingland treatment Manuscript profile

Recognition of resistance and susceptibility of problematic bacteria such as Yersinia ruckeri and Aeromonas hydrophila in rainbow trout farms, in proper selection of antibiotics and infection control in breeding ponds. It plays an effective role. In this study, 100 diseased fish were collected from rainbow trout farms in Chaharmahal and Bakhtiari province and after performing biochemical tests and purification of Aeromonas hydrophila and Yersinia ruckeri species, using PCR test with specific primers were finally approved. Antibiotic susceptibility of bacteria was investigated by disk diffusion method by culture on Müller-Hinton agar medium. Examination of the results of antibiogram of Aeromonas hydrophila isolates showed that the highest resistance was related to the antibiotics ampicillin (100%), colistin (80%), enrofloxacin (80%), flumquin (80%) and then, Compared to tetracycline (60%) and fluorophenicol (60%) antibiotics. The most sensitive isolates were related to trimethoprim-sulfamethoxazole (60%) and phosphomycin (60%) antibiotics. Examination of the antibiogram results of Yersinia ruckeri isolates showed that the highest resistance among the isolates was related to the antibiotics ampicillin (100%), erythromycin (100), trimethoprim-sulfamethoxazole (100%) and colistin (83.34%) and then showed about 67% resistance to tetracycline, fluorophenicol and phosphomycin antibiotics. Resistance to the antibiotics flumequin, lincomycin + spectinomycin (lincospectin) and enrofloxacin were also observed to be 50%, which means that none of these antibiotics would be a viable option for the treatment of bacterial infections caused by Yersinia ruckeri. In order to avoid growing bacterial resistance and to take the most effective decision in terms of antibiotic therapy, usage of antibiotics without antibiogram must be avoided. . Manuscript profile
