Abstract
PURPOSE Piroplasmosis is responsible for anemia, fever, loss of physical activity and even death in equines. In epidemiological studies, accurate diagnostic tests are essential for detecting asymptomatic carriers. This study aimed to investigate the prevalence of infection in asymptomatic horses from Lorestan province, western Iran by developing a multiplex PCR. METHODS AND RESULTS Blood samples were examined by microscopy and multiplex PCR targeting the SSU rRNA gene of Theileria equi and Babesia caballi. Out of the total of 165 horses, 19 (11.51%) and 31 (18.78%) cases were positive for piroplasms by microscopy and PCR, respectively. The detection rates of both genera were significantly higher in multiplex PCR compared to microscopy (p < 0.0001). Compared with multiplex PCR, the sensitivities of microscopy for the detection of Babesia were only 28.5%. The prevalence of T. equi infection was significantly higher in summer (p = 0.035). The prevalence of B. caballi was significantly higher in males (p = 0.038). CONCLUSION Findings indicate that the multiplex PCR described here is a sensitive technique for the detection of piroplasm DNA in carriers. Furthermore, asymptomatic carriers must be considered as an important source of infection for equids living in this region.

Abstract
Background Acanthamoeba spp. is opportunistic amoeba that resides in water, soil, and air. Some pathogenic genotypes of the genus of Acanthamoeba can cause granulomatous amoebic encephalitis (GAE) in people with a defective immune system. The parasite can also cause Acanthamoeba keratitis (AK) among contact lens users. This study was conducted to isolate and identify the Acanthamoeba genotypes in water resources in Lorestan province, western Iran. Methods Collected 72 water samples from surface and groundwater (springs and aqueducts) in Lorestan province. Samples were filtered and cultured in non-nutrient 1.5% agar medium covered with Escherichia coli (E. coli) at 25 °C. DNA extraction was done and the PCR reaction was performed to detect the Acanthamoeba spp. The positive PCR products were sequenced to determine the genotypes of Acanthamoeba. Results Out of 72 examined water samples, 23.61% were positive for Acanthamoeba sp. by PCR. From PCR-positive samples, 8 (47.05%) samples were T4 genotypes and others were other Acanthamoeba genotypes (T1-T23). Therefore, approximately half of the genotypes belong to the pathogenic T4 genotype. Conclusions The water examined samples in western provinces of Iran have the potential risk factor for public health. Therefore, the efforts of healthcare providers are needed to identify, train, and prevention from human infections.

Abstract
Community-based ecotourism (CBET) provides benefits to society members, especially concerning to the environment, by giving them the opportunity to influence and participate in the development of tourism. Lorestan province in the west of Iran is influenced by this phenomenon by having specific CBET opportunities in different economic, social, environmental and physical dimensions. The purpose of this study was to develop a sustainable community-based ecotourism (SCBET) model using the qualitative content analysis (with a deductive method in the form of the Hartmut model). The documents used included a systematic study of 45 international articles, 12 local articles, 2 books and in-depth interviews with 11 local experts. The results showed that the crystallization of CBET can be formed in the form of a four-component model (including planning, implementation, evaluation and situation analysis). In this model, four stages of the process of implementing community-based tourism (CBT) have been presented, in all of which the participation of researchers, ecotourists, policymakers and local people have been of great importance. Finally, the extracted categories for CBET sustainability were matched with the standards of the Global Sustainable Tourism Council (GSTC) (including sustainable management, cultural sustainability, socio-economic sustainability and environmental sustainability) and the final SCBET model was presented. This model can be useful for policy makers for decision-making and planning in the SCBET field.

Abstract
Renal disorders are able to make patients more susceptible to infections, including those caused oral cavity infections. Today, it has been proven that during end stage renal failure, hemodialysis results in acquired immune response defects through failings of humoral and cell-mediated immune. This survey was intended to assess the molecular epidemiology and associated risk factors of Entamoeba gingivalis and Trichomonas tenax as the main oral cavity protozoa in hemodialysis patients in Lorestan Province, western Iran. The investigation was performed on 73 hemodialysis patients referring to hemodialysis centers of Lorestan Province, Iran during May 2021 to February 2022. The frequency of oral cavity protozoa was investigated using microscopic and conventional polymerase chain reaction (PCR). A provided questionnaire with a number of demographical information and related risk factors was completed for each patient. The results showed that E. gingivalis and T. tenax parasites were found in 18 (24.6%) and 20 (27.4%) of the hemodialysis participants by microscopic and PCR test, respectively. Among samples, 13 (17.8%) of the hemodialysis participants were infected with E. gingivalis; whereas 7 (9.6%) of the participants were positive for T. tenax. No significant association was reported between gender, age, education, flossing, use of mouthwash, and prevalence of oral protozoa in hemodialysis participants. However, a significant correlation was observed among between living in rural regions (OR = 13.16; 95% CI = 2.64-56.81; p = 0.002), brushing teeth (OR = 8.51; 95% CI = 1.71-42.3; p = 0.009) and prevalence of oral protozoa in hemodialysis participants. The findings of these epidemiological study clearly showed the high frequency of oral cavity parasites in hemodialysis patients in Lorestan Province, Western Iran. Awareness of the main risk factors for oral cavity parasites particularly teeth brushing is necessary in refining public and oral health policies in hemodialysis patients. Consequently, dental practitioners, nephrologist, and urologist must be alert of these risk factors to carefully identify and achieve oral health concerns in hemodialysis patients to prevent the oral diseases and infections.

Abstract
Background We aimed to study the frequency and risk factors of oral cavity protozoa (Trichomonas tenax and Entamoeba gingivalis) in pregnant women in Lorestan province, western Iran. Methods The current cross-sectional descriptive work was performed on 200 pregnant women referring to health centers of Lorestan Province, Iran during August 2021 to February 2022. Two specimens were obtained from each women by means of sterile swabs from saliva and dental plaques. The frequency of oral cavity protozoa was investigated using microscopic and conventional polymerase chain reaction (PCR). Results E. gingivalis and T. tenax parasites were found in 41 (20.5%) and 46 (23%) of the pregnant women by microscopic and PCR test, respectively. Among positive samples, 29 (63.1%) of the pregnant women were infected with E. gingivalis; whereas 19 (36.9%) of the participants were positive for T. tenax. In the multivariate model, living in rural regions (p < 0.001) and brushing teeth (p = 0.021) were considerably linked with the prevalence of oral cavity parasites. Conclusion The current study evidently exhibited the high frequency of oral cavity parasites (E. gingivalis and T. tenax) in pregnant women in Lorestan province, Western Iran. Awareness of the main risk factors for oral cavity parasites especially teeth brushing is necessary in refining public and oral health approaches in pregnant women. Thus, dental practitioners and gynecologists must be alert of these risk factors to carefully identify and manage oral health concerns in pregnant women to prevent the oral diseases and infections.

Abstract
Identifying landslide-prone areas is an essential step in assessing landslide risk and reducing landslide damage. In this paper, GIS-based spatial analysis has been used to prepare the landslide susceptibility (LS) map in the north of Lorestan province in western Iran. For this purpose, three main criteria and their sub-criteria were identified as causative factors including geology and topography (i.e., distance from the fault, lithology, slope, aspect, and elevation), climate (i.e., rainfall and distance from the river), and environmental parameters (i.e., distance from the road, land-cover, NDVI). One hundred thirty-six known landslides were randomly divided into training ([Formula: see text] 70%) and validation ([Formula: see text] 30%) datasets. This study is based on the integration of popular analytic hierarchy process (AHP), frequency ratio (FR), and the fuzzy gamma operator (FGO) techniques. AHP was utilized to prioritize causal factors and fuzzy technique was applied in two stages of factor map fuzzification and calculation of sub-criteria maps and then overlap of fuzzified map layers. The fuzzy membership (FM) values were determined based on the FR method, which was normalized between the ranges of 0 and 1. Finally, LS zoning maps were estimated in five susceptibility classes (very low, low, moderate, high, and very high). Validation processes by comparing the three output maps with the layer of validation landslides in the study area and area under receiver operating characteristic curve confirm that the gamma value of 0.9 (AUC = 0.88) offers a more accurate LS map compared to other gamma values. The results of this study will be reliable for landslide risk reduction strategies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lorestan Province (Iran) has a great diversity of habitats and plant diversity and the people living in this province have a good knowledge of herbal therapies. AIM OF THE STUDY In this study, the authors aimed to identify and report the medicinal plants used in the folk medicine of Lorestan. MATERIAL AND METHODS The indigenous medicinal information was collected with a semi-structured open-ended questionnaire, interviews, and personal observations. The relative importance of the species were estimated through frequency of citations (FC). RESULTS and discussion: A total of 555 plants belonging to 91 families were identified. The plants belong to Asteraceae with 62 species followed by Lamiaceae (56), Apiaceae (44), Fabaceae (41), and Brassicaceae (31). The plants were mostly used as a decoction or eaten raw (32%). Leaves (22%) were the most utilized plant parts followed by shoots (16%), and seeds (13%). Thymus daenensis, Thymus eriocalyx, Mentha longifolia, Mentha spicata, Mentha piperitha, Alium sativum, Quercus infectoria, Quercus persica, Ziziphora clinopodioides, and Malus domestica had the highest FC values. Most of the plants were used for gastrointestinal, respiratory, and skin problems. CONCLUSION Lorestan is a region rich in medicinal plants. The local knowledge of herbal therapies can be used as complementary medicine, particularly by people in remote areas and as a guide for the future pharmacological and phytochemical studies. While the known medicinal plants can be harvested or cultivated for medical and pharmaceutical purposes, the less known plants with high FC scores can be investigated phytochemically and pharmacologically in the future studies.

Abstract
This study aimed to determine the prevalence and early detection of hypodermosis in goats by the investigation of Przhevalskiana larvae and sera collected from the infested animals. This study was conducted in Lorestan province, located in the South-West of Iran, from April 2017 up to April 2018. A total of 3350 goats slaughtered in Lorestan abattoirs were investigated by clinical-parasitological examinations in different periods. The larvae were collected from the back and flank regions of the slaughtered goats. The number of infested animals, gender and age, number of maggots present on the body of each animal, location, and larval stage of warble flies were recorded in this study. To detect an infestation in the early period, a total of 150 blood samples were randomly collected from the field animals in Lorestan, Iran. The morphological findings showed that out of 3350 goats examined, 706 (21.07%) goats were infested. Furthermore, three species of Przhevalskiana, including P. Silenus (n=726, 50.07%), P.crossii (n=440, 30.43%), and P. aegagri (n=284, 19.59%) were recognized as the causative agents of goat hypodermosis in this province. No significant difference was observed between genders and/or among the age groups (P&gt;0.05). The anti-Przhevalskiana antibodies in the serum samples were detected using ELISA from August up to mid-September (summer). Clinical diagnosis of infestation was usually performed from late October until mid-March (winter) by visual observations and direct palpation of warbles in the back and flank regions of the animals. It could be concluded that the use of ELISA can help to detect hypodermosis among goats in the early stages.

Abstract
Background: Hepatitis B virus is one of the transfusion transmissible infections. Despite the availability of hepatitis B virus (HBV) vaccine and screening tests but still danger of virus transmission via blood transfusion is high in some regions. The objective of this study was to determine the trend of seroprevalence of hepatitis B in over an 11-year period (2005–2015). Methods: In this study, 355,083 blood donors were estimated for hepatitis B surface antigen (HBs Ag) seropositivity during 2005–2015 who referred to blood infusion centers of Lorestan province. Third-generation ELISA method was used to detect HBs Ag. Results: The prevalence of HBs Ag in blood donors was 0.29% (1017). It was decreased steadily from 2005 to 2015 (0.68% to 0.12%) but increased in 2008 year. The trend prevalence of HBs Ag seropositivity significantly decreased over the study period (P < 0.001). The decline in HBV infection rates was more prominent in regular and repeated donor's groups compared to people who donated blood for the first time (P < 0.001). Conclusions: The result of present study was indicated, Lorestan city in west of Iran can be classified as a low-income region because the low prevalence of HBs Ag in blood donors. Also the prevalence of HBs Ag in first-time donors was higher than other groups.

Abstract
Snails are creatures present in various ecosystems that, in addition to being present in human surroundings, some of them are also important in veterinary medicine and medicine as the intermediate hosts of Digenean trematodes. The present study was conducted to identify and determine the geographical distribution of freshwater snails and investigate the relationship of variables, such as season and geographical region, with snail species and dispersion in Lorestan in the west of Iran. A total of 4400 samples of freshwater snails were collected using the multistage sampling method (i.e., stratified, cluster, and randomized) from 110 points in five geographical regions in four seasons and then identified based on their morphological characteristics by diagnostic keys. The ArcGIS software (version 10.3) was used to evaluate the spatial distribution of the freshwater snails. In this study, seven species of freshwater snails were identified in six families belonging to six genera, namely Melanopsis doriae (6.30% of the variation in species), Theodoxus doriae (5.55%), Bithynia tentaculata (43.22%, the dominant species), Physa acuta (24.98%), Lymnaea truncatula (9.75%), Gyraulus euphraticus (8.18%), and Lymnaea gedrosiana (2.02%). The geographic distribution of freshwater snails was recorded across five regions in 22 points per region for every season. The spatial distribution maps showed that the distribution of freshwater snails varies according to region and season (P&lt;0.001). The obtained results revealed the effects of season and geographical region on the distribution and population density of snails in the province. These data can be used for the implementation of control programs against parasitic diseases in the region, including trematodes.

Abstract
BACKGROUND Despite the progress made, animal bites and rabies are one of the important health problems in the country. The purpose of this study was to investigate the epidemiology of animal bites and rabies during 2004-2014 in Lorestan Province to prevent them in population of the province for the future prospective aspects. MATERIALS AND METHODS In a descriptive cross-sectional study, all those cases bitten in the province, during 2004 and 2014, were studied. The required information about the age, sex, the bitten organ, type of the invasive animal time, and location of the event were collected in questionnaires and then analyzed. RESULTS The total number of cases of animal rabies during the period of study was 43,892, shown at the rate of 223.23 in 100,000 people. Seventy-eight percent of animal bites in rural areas, 41.42% in the ages 10-29-year-old, 26.8% of cases were students, 56.77% leg bites, and 82.5% of dog bites. Four cases of human rabies were observed during this period. CONCLUSIONS Rate of animal bites and rabies is high in Lorestan Province. Controlling animals such as dogs and cats in the province through training people at risk, especially among the students, rural areas and inter-sectorial coordination to eliminate stray animals should be considered over and over. Preventive actions to avoid bites are a priority.

Abstract
Fasciola spp. and Dicrocoelium dendriticum as liver flukes, contaminate ruminants and other mammalian extensively and cause major diseases of livestock that create considerable economic losses. This retrospective study has been done to evaluate contamination rate of slaughtered animals with fasciolosis and dicrocoeliosis at Lorestan abattoirs. In this survey, prevalence rate of fasciolosis and dicrocoeliosis in slaughtered animals in a 3-year period (2010-2013) has been analyzed. A total of 356,605 livestock including 265,692 sheep and 90,913 goats were slaughtered in the 3-year period and overall 39,613 (11.1 %) livers were condemned. Fascioliasis and dicrocoeliosis were responsible for 6.3 and 4.8 % of total liver condemnations in this period, respectively. Fasciola spp. and D. dendriticum infection in sheep (7.1 and 5.6 %, respectively) were considerably higher than goats (3.9 and 2.6 %, respectively). The annual prevalence rates showed a significant decline in the fasciolosis and dicrocoeliosis infection in goats (p < 0.001). Data showed significant seasonal pattern for distomatosis in sheep and goats (p < 0.001). Liver condemnations due to fasciolosis were prevalent in sheep and goats slaughtered during spring and autumn, respectively, whereas dicrocoeliosis were common in spring season for both sheep and goats. This survey provides baseline data for the future monitoring of these potentially important parasitic infections in the region.

Abstract
OBJECTIVE To identify Leishmania using PCR. METHODS This study was conducted from April 2009 to March 2011 in order to identify Leishmania species in a new endemic area of CL in Lorestan, Iran. Samples were taken from 62 patients that referred to the health centers in different cities of Lorestan province, the presence of Leishmania was confirmed using direct smear and then grown in NNN media and mass cultured in RPMI 1 640 medium supplemented with 10% heat-inactivated fetal bovine serum. DNA was extracted from cultured promastigotes and used in ITS-PCR. RESULTS 45(72.6%) samples out of 62 showed a band in the range of 485 bp and 17 (27.4%) with a band in the range of 626 bp which were similar to standard strains of Leishmania tropica(L. tropica) and Leishmania major(L. major), respectively. 50 (65.80%) of samples were collected from people with no history of travel in at least a year prior to the onset which shows that indigenous source of infection. CONCLUSIONS Since the vector and reservoir of the two species are different, so precise and extensive control and prevention methods should be designed and carried out.
