“…However, Ali (2015) reported a much higher prevalence of double CLs (44.4%). The mean diameter of CL in the present study (2.2 mm) was consistent with that previously reported in the literature (Zarrouk et al, 2003;Ali, 2015).…”

“…Economically, dromedary camel exploitation appear problematic because of slow reproductive cycle (13 months of pregnancy) and high mortality of young (431,432). Reproductive losses in camel herds are due to infertility (uterine infection), pregnancy loss (infectious pathogen-induced abortions), mastitis (female udder infections), and neonatal diseases (433).…”

“…The riding of the dromedary camels as saddle animal is regularly practiced in most countries of the Maghreb, particularly among the Saharawis (Morocco) or Tuareg (Algeria, Libya) populations. Dromedary camels are also attracting tourists around races that are very popular in the countries of the Arabian Golf and North Africa (432,442,443). Over many years, typical racing dromedary camels (slim, lightweight, high-speed) were selected to confer highest sports performance ( Table 6).…”

Coxiella burnetii in Dromedary Camels (Camelus dromedarius): A Possible Threat for Humans and Livestock in North Africa and the Near and Middle East?

The "One Health" concept recognizes that human health is connected to animal health and to the ecosystems. Coxiella burnetii-induced human Q fever is one of the most widespread neglected zoonosis. The main animal reservoirs responsible for C. burnetii transmission to humans are domesticated ruminants, primarily goats, sheep, and cattle. Although studies are still too sparse to draw definitive conclusions, the most recent C. burnetii serosurvey studies conducted in herds and farms in Africa, North Africa, Arabian Peninsula, and Asia highlighted that seroprevalence was strikingly higher in dromedary camels (Camelus dromedarius) than in other ruminants. The C. burnetii seroprevalence in camel herds can reach more than 60% in Egypt, Saudi Arabia, and Sudan, and 70 to 80% in Algeria and Chad, respectively. The highest seroprevalence was in female camels with a previous history of abortion. Moreover, C. burnetii infection was reported in ticks of the Hyalomma dromedarii and Hyalomma impeltatum species collected on camels. Even if dromedary camels represent <3% of the domesticated ruminants in the countries of the Mediterranean basin Southern coast, these animals play a major socioeconomic role for millions of people who live in the arid zones of Africa, Middle East, and Asia. In Chad and Somalia, camels account for about 7 and 21% of domesticated ruminants, respectively. To meet the growing consumers demand of camel meat and milk (>5 million tons/year of both raw and pasteurized milk according to the Food and Agriculture Organization) sustained by a rapid increase of population (growth rate: 2.26-3.76 per year in North Africa), dromedary camel breeding tends to increase from the Maghreb to the Arabic countries. Because of possible long-term persistence of C. burnetii in camel hump adipocytes, this pathogen could represent a threat for herds and breeding farms and ultimately for public health. Because this review highlights a hyperendemia of C. burnetii in dromedary camels, a proper screening of herds and breeding farms for C. burnetii is urgently needed in countries where camel breeding is on the rise. Moreover, the risk of C. burnetii transmission from camel to human should be further evaluated.

“…Literatures are scanty on the physiological and hormonal changes during pregnancy and periparturient period in she camels. Female dromedary camels' reproduction is characterized by a seasonal activity and induced ovulation [1], and exhibits follicular cycles with follicles developing and regressing successively. Progesterone hormone level in females is a very useful tool to monitor pregnancy in camels [2].…”

Hormonal Profile, Antioxidant Status and Some Biochemical Parameters during Pregnancy and Periparturient Period in Dromedary She Camel

2017

THIS STUDY aimed to determine the changes in the hormonal and biochemical profile of pregnant dromedary camels to provide a baseline data under Egyptian climatic conditions. Blood samples were collected from15 pregnant she-camels aged 8-11 years old just postconception and thereafter monthly during gestation period and during periparturient period (at days 15, 7,4and 1prepartum,at parturition and at days 1, 4, 7 and 15 postpartum).Progesterone level increased significantly (P<0.05) after conception and during the1 st and the 2 nd trimester of pregnancy then declined significantly (P<0.05) during the 3 rd trimester. Meanwhile its level decreased significantly (P<0.05) during periparturient period. Cortisol level significantly (P<0.05) increased at the 3 rd trimester and continued increasing significantly during prepartum period with a maximum level on the day of parturition after that it was markedly decreased during the few days postpartum to day 15 postpartum. Thyroid hormones levels were significant (P<0.05) decreased in their levels from early to late gestation then increased significantly (P<0.05) from day of parturition to day 15 postpartum. Total protein and albumin were significantly low (P<0.05) in the 2 nd and the 3 rd trimesters than the first one with no significance alterations in globulin levels. Total antioxidant, glutathione and ascorbic acid levels were lower in the 3 rd trimester than others, whereas the levels were relatively low in prepartum than 15 days postpartum. Malondialdehyde concentration was significantly increased (P<0.05) during late pregnancy period as a result of the physiological stress of pregnancy
