Abstract

Context: The Ghamishloo National Park and Wildlife Refuge, located in the west part of Isfahan province, is one of the most important protected areas in the country. This area, as one of the semi-desert ecosystems in the central part of Iran, is the habitat of numerous wildlife species (especially Gazella subgutturosa, Ovis orientalis and so on). Aims: Since the Persian Gazella (G. subgutturosa) is one of the most important protected wildlife species in Iran, parasitic diseases (along with other problems) cause significant decrease in the population of this animal and finally lead to extinction. Materials and Methods: From early May to the late August 2016, seventy fresh dung samples of G. subgutturosa and 10 livestock dung samples were collected and were immediately transported to the laboratory. Then the Clayton Lane method was used to investigate the parasite eggs, and the Berman method was applied to prepare and identify the parasite species. Results: The results showed that five samples had parasite. These samples were cultured to identify the parasite type. According to the results, 7.15% (2.86% Trishuris, 2.86% Moniezia and 1.43% Marshalagia parasites) of the samples were contaminated with the intestinal parasite eggs. Thereafter, some strategies were presented for controlling and monitoring the parasite pollutions in the region.

 Introduction



One of the main diseases, which has affected wildlife in the world, is intestinal parasites infection. Ruminants are, undoubtedly, the one of the most important helminth infection hosts. There are about 50 species in the gastrointestinal tract, five species in the lungs and at least five species in the liver of ruminants in Iran. Other organs are also subjected to helminth infections, however, are not associated with certain clinical signs. Nevertheless, they have negative effects on livestock products and reduce productions of meat, milk, wool, and twinning (in small ruminants). They also make them vulnerable to the other diseases and cause high economic losses.[1],[2],[3] Persian Gazella is a native, protected species in the central and southwest Asia. Neck below of the male Gazella becomes tumescent during the mating season and thus this species is known as the goitered gazelle. This species has an average size. The males have relatively long S-shaped horns which look like a Cheng. Females have usually no horns [Figure 1].{Figure 1}

 Materials and Methods



The Ghamishloo National Park and Wildlife refuge with 113,000 ha is located in the 45 km of the north west of Isfahan city in central Iran [Figure 2].{Figure 2}

So far, 344 plants, 37 mammals, 82 birds and 32 reptile’s species, along with two amphibians species have been identified and recorded in this area [Figure 3].{Figure 3}

By the interval of visiting from early May to the late August 2016, 70 fresh dung samples, especially near the watering places, in the random way were collected. Fresh and soil-free dung samples [Figure 4] were collected by using disposable gloves and were placed separately in 100 g plastic containers.{Figure 4}

The sampling time and date, geographic coordinates, habitat name and the dung characteristics such as the consistency were recorded in each site. The collected dung samples were transported to the parasitology laboratory. The Clayton Lane method [Figure 5] was used to investigate the parasite eggs, and the Berman method was applied to prepare and identify the parasite species. The samples were mathematically analysed by using the Statistical Package for the Social Sciences software, and Geographic Information System software were used for mapping purpose [Figure 6].{Figure 5}{Figure 6}

 Results



As it can be observed from the cultivation results, shown in [Figure 7], five out of the 70 dung samples (7.15%) were infected by parasite, and 35 samples (50%) were contaminated by oocyte [Figure 8], and 30 samples (42.86%) were non-polluted. Five samples, which were contaminated by the parasite eggs, were cultured to identify the parasite type via stool cultures.{Figure 7}{Figure 8}

 Discussion



Trishuris [Figure 9] is one of the observed parasites in the studied samples. In other studies,[4],[5],[6] this parasite has been observed in ruminant wildlife. Trishuris infection is 2.86% that is consistent with Persian fallow deer study and shows lower rates when compared to other studies. The second observed parasite was Marshalagia [Figure 10] that was also reported by Morgan et al.[7] and Tavassoli and Khoshvaghti.[8] Marshalagia infection percentage was 1.43 which shows lower rate of infection compared to other studies. Morgan et al.[7] also reported that simultaneous grazing of the wildlife with livestock in pastures had the transmission potential of a wide range of helminth parasites between animals and domestic ruminants. The third parasite type observed in the current study was Moniezia [Figure 11], which has also been reported by Masamha et al.[9] and Cook et al.[10] Moniezia parasite was detected in two deer species out of 70 studied species that reveals a smaller percentage in comparison with other studies. The main reasons for these differences in the prevalence of intestinal parasites in the deer population in this protected area compared with similar studies in other parts of the world might be the feeding method, age, appropriate ranges, weather conditions (dry air), ruminant’s strong immune system and pristine of the region.{Figure 9}{Figure 10}{Figure 11}
