The study was carried out over a 5-month period on a total of 100 dromedaries.<br \/>\nDung samples were analysed using different methods such as flotation, sedimentation, and Ziehel-Neelsen staining for research of the cryptosporidiosis. Data showed an overall infestation rate of 78%, with the presence of the following parasites: <em>Cryptosporidium<\/em> spp. (60%), Nematodes: <em>Nematodirus<\/em> spp. (23%), <em>Strongyloides<\/em> spp. (4%), <em>Marshallagia<\/em> spp. (2%), and <em>Cooperia<\/em> spp. (3%), different protozoaires: <em>Eimeria<\/em> spp. (20%), <em>Neobalantidium<\/em> spp. (2%), and <em>Balantidium coli<\/em>, cestodes (6%), <em>Moniezia<\/em> spp. (3%), <em>Multiceps<\/em> spp. (2%), <em>Diphillobothrium<\/em> spp. (1%), and trematodes: <em>Fasciola h\u00e9patica<\/em> (4%) and <em>Paramphistomum<\/em> spp. (1%). The results showed a significant influence of study site on the parasitic infestation rate (<em>P<\/em>=0.039).<br \/>\nOther factors (sex, age and clinical aspect) had no significant influence. To conclude, gastrointestinal parasites are a major problem of indigenous camels under traditional husbandry. Therefore, parasite control programmes are recommended to increase the productivity of this useful animal.<\/p>\n<p><strong>Key words:<\/strong> <em>dromedary; parasite; gastrointestinal; risk factors; Laghouat; coproscopy<\/em><\/p><\/blockquote>\n<p><a name=\"Introduction\"><\/a><a class=\"alignright\" href=\"#menu\"> &#9650;<\/a><\/p>\n<h2>Introduction<\/h2>\n<hr \/>\n<p>Camel belongs to the class of <em>Mammalia<\/em>, order <em>Artiodactyla<\/em>, sub- order <em>Tylopoda<\/em> and family <em>Camelidae<\/em> (Al Haj and Al Kanhal, 2010). For centuries, the camel has been a very important animal in desert areas due to its ability to withstand very harsh conditions (high temperature and drought), to provide milk, meat, its use as a mean of transport (Faye <em>et al<\/em>., 2014; \u0110uri\u010di\u0107 <em>et al<\/em>., 2020a, b) and its ability to digest poor forage compared to other domestic ruminants (Kayouli <em>et al<\/em>., 1995).<\/p>\n<p>The camel is present in 35 countries around the globe, 18 of which are African nations (Bourddane, 1998). In Algeria, the camel population is estimated at 140,000 individuals (Afoutni, 2011; Djireb, 2015).<br \/>\nCamels in Algeria are not the major domestic animal, but are considered a good source of milk and meat to nomadic and urban habitants, and are used for other purposes such as transportation (Saidi <em>et al<\/em>., 2021).<\/p>\n<p>This animal is frequently infested by gastrointestinal parasites, which decreases productivity (Richard, 1989, Mahmuda <em>et al<\/em>., 2014). Among the many pathologies caused by these parasites, helminthiasis represent an important internal parasitosis affecting camels.<\/p>\n<p>Several studies have reported the occurrence of different gastrointestinal parasites in camels in different parts of the world (Sharrif <em>et al<\/em>., 1997; Magzoub <em>et al<\/em>., 2000; Bekele, 2002; Dia, 2006). However, few studies have examined these diseases in Algeria. Under this context, this study was conducted to determine the prevalence rate of gastrointestinal parasitism and to identify the different parasitic species and influence of certain factors (sex, age, and site of the study) on the infestation rate in the Laghouat region.<\/p>\n<p><a name=\"Materials\"><\/a><a class=\"alignright\" href=\"#menu\"> &#9650;<\/a><\/p>\n<h2>Materials and methods<\/h2>\n<hr \/>\n<h3>Study area description<\/h3>\n<p>The study was conducted in the Laghouat region of southern Algeria, located about 400 km south of Algiers, from February to May 2019.

To our knowledge, there are no previous studies conducted in this region with this objective. The results obtained showed a high prevalence of different species of gastrointestinal parasites (78%). Our data is important in comparison with those found by Abdalla <em>et al<\/em>. (2016) in Mogadishu (50.3%), and in Pakistan (60%) by Mahfooz (2006) and by Azhat <em>et al<\/em>. (2013) (37.33 %). However, our results are comparable to those found in Somalia (Magan <em>et al<\/em>., 2017), in Sokoto (Mahmuda <em>et al<\/em>., 2014), and in Ethiopia (Demelash <em>et al<\/em>., 2014) with rates of 79%, 78%, and 80.73%, respectively, and lower than those reported in Egypt (90.9%) (Khalif, 2009), Nigeria (92.4%) (Bamaiyi and Kalu, 2011), and Jordan (98%) (Sharrif <em>et al<\/em>., 1997).<\/p>\n<p>In total, 15 species of gastrointestinal parasites were found in 100 animals examined, with varying prevalence.<br \/>\nThe predominant presence was <em>Cryptosporidium<\/em> spp. eggs (58%). This value is significantly higher than those reported in Iran (3.3%, Nouri <em>et al<\/em>., 1995; 37.6%, Razavi <em>et al<\/em>., 2009; 16.9%, Nazifi <em>et al<\/em>., 2010; 20.3%, Sazmand <em>et al<\/em>., 2012;, 2.4%, Radfar <em>et al<\/em>., 2013; and 0.5%, Shahraki <em>et al<\/em>., 2016).<\/p>\n<p>Cryptosporidiosis is a contagious parasitic disease that affects several animal species and even humans. Their oocysts are highly infectious with a high environmental resistance capacity; this could explain their high prevalence rate encountered in this survey. They are also known for having an extremely common self-infestation ability (Lakhal and Labyadh, 2017).<\/p>\n<p>In this study, <em>Eimeria<\/em> spp. was encountered at a rate of 20%. This frequency was similar to that reported by Abubakr (2000) in Bahrain. However, there results were lower than those recorded in Iran (24%) by Radfar <em>et al<\/em>. (2013). In a study by Rewatkar <em>et al<\/em>. (2009), the prevalence of Eimeria spp was 25%. Mirza (1976) recorded a rate of 40% in Iraq, Gill (1976) recorded a rate of 11% in India, and Kawasem <em>et al<\/em>. (1983) reported a rate of 14% in Saudi Arabia.<\/p>\n<p>Coccidia are usually self-limiting because they lack the ability to re-contaminate, and the asexual cycle can only be performed three times in the same host (Fowler, 1995). This could partially explain the infestation rate reported in this study.<\/p>\n<p><em>Nematodirus<\/em> spp. were found with a prevalence rate higher than a report from Egypt (13.7%) by Ismail <em>et al<\/em>. (2004). A study performed by Rewatkar <em>et al<\/em>., (2009) recorded a rate of 10.71% which is significantly lower than the rate recorded by Mostapha <em>et al<\/em>. (2013) in Jordan (98%). <em>Nematodirus<\/em> parasitosis is frequent during spring and early summer. This coincides with the period of our field study. It is due to a sudden infestation by large amounts of <em>Nematodirus<\/em> larvae, and these parasites\u2019 eggs have a particularly strong resistance. If the temperature rises above 10\u00b0C, the eggs will be stimulated and hatch rapidly to give several larvae over a short period of time (Autef, 2008).<\/p>\n<p><em>Strongyloides<\/em> spp. were present with a rate lower than those recorded in Ethiopia (56%, Abdalla <em>et al<\/em>., 2016; 67%, Kashun <em>et al<\/em>. 2014; 23%, Magan <em>et al<\/em>., 2017), in Pakistan (8%, Mahfooz <em>et al<\/em>., 2006), and in Sokoto (9.26%, Radfar <em>et al<\/em>., 2013).<br \/>\nHowever, our results were higher than reports from Egypt (1.2%, Khalif, 2009).<\/p>\n<p>In this study, the infestation rate of <em>Fasciola hepatica<\/em> was higher than reports from Ethiopia (2.1%, Magan <em>et al<\/em>., 2017), and Mogadishu (0.6%, Abdalla <em>et al<\/em>., 2016). The prevalence rate of <em>Moniezia<\/em> spp. was lower than recorded in Pakistan (4%, Mahfooz <em>et al<\/em>., 2006), Egypt (8.16%, Nagwa <em>et al<\/em>., 2013), Mogadishu (4.2%, Abdalla <em>et al<\/em>., 2016), and Ethiopia (8.4%, Magan <em>et al<\/em>., 2017). <em>Balantidium coli<\/em>, had a prevalence rate similar to Yakaka <em>et al<\/em>. (2017) in Nigeria (1%), and lower than what Rewatkar <em>et al<\/em>. (2009) found in Iran (74%). <em>Marshallagia<\/em> spp. prevalence rate was lower to that recorded in Iran by Borji <em>et al<\/em>. (2010) (4%).<\/p>\n<p><em>Trichuris<\/em> prevalence rate is significantly lower than that noted in Iran (14%, Radfar <em>et al<\/em>., 2013) and in Egypt (17.36%, Nagwa <em>et al<\/em>., 2013). In contrast, Sahnoune (2011) recorded an infestation rate of 45.45% in Oued Souf (Algeria).<br \/>\nThis huge difference between the results is likely due to the research techniques (coproscopy) and highlighting of adult worms.<\/p>\n<p>Among the results reported in this study, the rates of cases of single and polyparasitism were lower rates than those recorded by Mahmuda <em>et al<\/em>. (2014) in Sokoto (60.28% for single infestations and 39.74% for double infestations and more). On the contrary, in Pakistan the authors reported higher prevalence rates (7.36%, (Alvi <em>et al<\/em>., 2014). In Egypt, Nagwa <em>et al<\/em>. (2013) reported a comparable prevalence rate for single parasitism (40%).<br \/>\nPolyparasitism is explained by the fact that some portions are more parasitized than others. This difference in parasite association could be explained by the difference in several environmental factors that can positively or negatively affect the distribution of parasites and the excessive disproportion when referring to infested gastrointestinal compartments (Tamssar, 2006). It can be also due to the distribution of camels, the study site or certain unfavourable conditions, such as an unbalanced diet, climate or age (Radfar <em>et al<\/em>., 2013). The presence of polyparasitism confirms the existence of favourable environmental indices to the survival and perpetuation of parasites (Mahmuda <em>et al<\/em>., 2014).<\/p>\n<p>In the present study, statistical analysis revealed that site study was the only parameter to cause a significant difference.<\/p>\n<p>Parasite infestation by sex showed that males were more infested than females, in agreement with the results of Anwar and Khan (1998) in Pakistan, while Bamaiyi and Kalu (2011) revealed that females were more infested than males. Statistical analysis however did not reveal a significant difference.<\/p>\n<p>Parasitic prevalence in animals less than 1 year old was higher than in other age groups, with the lowest infestation rate in animals older than 15 years, though this difference was not statistically significant. In contrast, the parasitic prevalence rate in adults was higher than in the younger ages groups in studies conducted by Duguma <em>et al<\/em>. (2014) and Yakaka <em>et al<\/em>. (2017).<\/p>\n<p>Symptomatology is mainly represented by diarrhoea, though there was no statistically significant association between parasitism and diarrhoea. This data showed that the infested subjects do not always present a clinical symptomatology (diarrhoea does not reflect the existence of parasite infestations).<br \/>\nTherefore, positive camels are considered asymptomatic carriers; thus representing a source of contamination and spread of these infections in their environment. The remaining cases are linked to viral or bacterial disease or even nutritional problems (Daouia, 2012; \u0160mit <em>et al<\/em>., 2017).<\/p>\n<p>The prevalence rate of <em>Coccidia<\/em>, <em>Eimeria<\/em> spp. varied by study site. A higher prevalence rate was recorded in Laghouat than elsewhere, and this difference was significant, which is likely explained by the high density of the camels in this area.<br \/>\nThe remaining species appear to be stable and do not vary with the study site.<\/p>\n<p><a name=\"Conclusions\"><\/a><a class=\"alignright\" href=\"#menu\"> &#9650;<\/a><\/p>\n<h2>Conclusions<\/h2>\n<hr \/>\n<p>This study examined the gastrointestinal parasites in camels of the Laghouat region. The results indicate that camels are important reservoirs for different parasites which are responsible for several diseases. For future studies, it is suggested to widen and deepen our knowledge of the host-parasite interaction and to follow their evolution over time, while including other parameters, namely the effects of ecological factors.<\/p>\n<p><a name=\"Literatura1\"><\/a><br \/>\n<strong>References<\/strong><span style=\"color: #808080;\"><a onclick=\"toggle_visibility('Literatura');\" ><span style=\"color: #808080; cursor:pointer;\"> [&#8230; show]<\/span><\/a><\/span><\/p>\n<div id=\"Literatura\" style=\"display: none;\">&nbsp;<a class=\"alignright\" href=\"#menu\" onclick=\"toggle_visibility('Literatura');\"> &#9650;<\/a><\/p>\n<p style=\"font-size: small;\"><em>1.\tABDALLA, M.
