The study was designed to explore anatomical and histological vasculature changes in the female genital system of camel and serological aspects that might be responsible to maintain thermoregulation. Twenty-four adult female camels were sampled during breeding (November-April) and non-breeding (May-October) season. Blood was collected for estrogen, progesterone and cortisol level estimation. Genital organs were sampled and described after slaughtering. Samples were taken from the ovarian artery (OA), vein (OV) and arterio-venous complex (AVC), for light and scanning electron microscopy. Sections were stained with Hematoxylin and Eosin. (H&E), Masson’s trichrome, Weigert’s elastic and toluidine blue. Temperature and relative humidity were used to calculate stress indicator. Stress indicator was higher in non-breeding season (NBS). Anatomical and histological vasculature (OA, OV, AVC) dynamics were significantly higher in breeding season (BS) especially diameter of left OA. Parameters of OA were positively associated with estrogen level. Collagen, elastic, smooth muscles and mast cells were recorded least in BS compared to NBS. Unique venous structure, intra-mural venules (IMV), was discovered in tunica intima of OA, seen positively and negatively associated with estrogen and cortisol level in BS, respectively. Scanned electron-micrograph exhibited penetration and wrapping of OA by small thinned-walled venules that may form IMV. The AVC was too tightly packed to differentiate due to the collapse of the wall. Hormonal, seasonal, stress indicator and vascular dynamic of female genital system are interlinked and IMV in association with OA and OV may be proposed as the site of counter-current exchange in female reproductive system of the camel.

In the present case report, the comprehensive management of a bilateral mandibular fracture in a single-humped camel including pre-, peri- and post-operative cares is described. A one-year-old camel with the overhanging of the rostral part of the lower jaw which occurred seven days ago was presented. After clinical and radiographic examinations, a bilateral mandibular fracture at the caudal part of canine teeth was diagnosed. It was decided to repair the fracture surgically under general anesthesia. The camel was restrained in sitting position and was remained in this position during anesthesia and surgery period. After premedication with acepromazine (0.10 mg kg-1) and xylazine (0.20 mg kg-1) intramuscularly, anesthesia was induced using ketamine and diazepam intravenously (2.00 and 0.10 mg kg-1, respectively). Maintenance of anesthesia was performed by repeated doses of xylazine and ketamine intravenously (0.10 and 1.00 mg kg-1, respectively) as needed. After preparation of the oral cavity, the fracture was reduced and an interfragmentary wire and an interdental wire (1.00 mm diameter size) were applied on each side of the mandible for the fixation of fracture segments. After two months, the interdental wires were removed while the interfragmentary wires were left intact. Follow up the camel three months after surgery, showed the full ability of prehension and chewing of roughages by the camel.

Myiasis is a disease of vertebrate animals caused by different fly larvae. Wohlfahrtia magnifica is responsible for serious losses in animal husbandry in Eurasia. Larvae of W. magnifica parasitize several warm-blooded vertebrates and are responsible for a severe traumatic myiasis of mucosal membranes or wounds. This myiasis has been reported in many European areas, but for the first time was reported from Iran. Larvae infestation was observed in five camels out of 35 (14.28%) around the perinea and vaginal region of camels in a herd in southwest of Iran. The larvae samples were collected and transferred to the laboratory of parasitology for identification. This is the first report of infestation of a camel herd (camelus dromedarius) in Iran. The treatment was performed and prevented the loss from camels and improved their physical condition. Although the myiasis is not a lethal disorder, however knowledge of the disease is necessary from preventive, diagnostic and curative standpoint.

The kidney of camel is known to play a vital role in water conservation through the production of highly concentrated urine that may predispose animal to varieties of renal dysfunction. In camels renal disorders have received lesser attention in comparison with other animals, thus there is shortage of information in this area. The present study was conducted on 100 slaughtered camels (Camelus dromedaris) (200 kidneys) in Najaf-Abad district (Iran) to evaluate the frequency and types of renal disorders. Results demonstrated varieties of gross abnormalities in 14.00% of kidneys that out of them, 9.00% were confirmed by microscopic examination. Renal capsular pigmentation, medullary hyperemia, subcapsular calcification, cortical and medullar discoloration, hemorrhage in renal pelvis, nephrolithiasis and hydatidosis were recorded in 3, 6, 5, 6, 3, 2 and 3 cases, respectively. In addition, capsular melanosis, acute tubular necrosis, chronic interstitial nephritis, caseous necrosis, calcification, medullary hyperemia, and hydatid cyst were confirmed by histopathological examination in 3, 5, 1, 3, 2, 2, and 2 cases, respectively. Our findings indicate the presence of many types of renal disorders which may relate to dehydration, bacteremia or nephrotoxicosis. In addition capsular melanosis in male camel was recorded for the first time and its etiology remains to be addressed.

A cross-sectional study was carried out to determine the prevalence and species of camel mange mite infestation in Raya-Azebo district, Northern part of Ethiopia. Accordingly, Three hundred and eighty-four camels were examined and mange mite infestation was detected on 64 of camels. Only Sarcoptes scabiei var. cameli was identified as the only mite species in all skin scraping samples collected from the suspected mange mite lesions. There was significant difference in the prevalence of mange mite infestation between male and female camels (p < 0.05) but no significance difference was observed among the age groups and body condition score of camels (p > 0.05). The result indicated that camel mange mite infestation was a problem in northern part of Ethiopia, hence, further studies and strategic control measures are recommended to reduce the effect of mange mite infestation on camel husbandry.

Camel trypanosomosis is a life-threatening disease in the camel species and responsible for severe economic losses either in milk or meat productions. This study was carried out on the south-east area of Algeria on 100 camels of various ages and either sex from two herds. Microscopic examination of blood smears revealed higher levels of trypanosomosis caused by Trypanosoma evansi, an elongated parasite with a kinetoplast and a single nucleus located in its half-length and one flagellum with great heterogeneity. This first investigation reveals higher infection rate than those observed in other countries using blood smears, the trypanosomosis attack has reached an alarming level and the occurrence of trypanosomosis at this high level on blood smears is like "the tree that hides the forest" and make up a serious and potential danger both on animal and public health. Therefore, radical preventive and offensive drastic measures must be taken against this menacing disease at the critical points to prevent the economic losses and to avoid possible human transmission.

Linguatula serrata, well known as tongue worm; is an aberrant cosmopolitan parasite, which inhabits the canine respiratory system (final host). The discharged eggs infect many plant feeder animals including human causing visceral and nasopharyngeal linguatulosis which is known as “Marrara syndrome”. In current study, the prevalence of infection with L. serrata nymphs in mesenteric lymph nodes (MLNs) of slaughtered camels was investigated in Isfahan Province, Iran. The MLNs of 232 slaughtered camels, including 115 females and 117 males, were examined for L. serrata nymphs. Camels were categorized into four age groups, namely under six months, six months to two years, two to four years and greater than four years. Also, the morphometrics of the nymphs were measured using the classic parasitology methods. Results showed that 21.12% of examined camels were infected with L. serrata. Age and sex had no significant effect on the prevalence of this parasite in camels. The size of the different parts of nymphs’ body were recorded and evaluated. The infection rate to the nymphs of parasite in hemorrhagic and black-colored lymph nodes were significantly (P ≤ 0.05) higher than the infection rate in normal-colored nodes. Also, results showed that in soft lymph nodes, the infection rate was significantly (P ≤ 0.05) more than those of normal and hard nodes. A high prevalence of infection in camels suggests possibility of similar high rate of infection in other animals, and people in the investigated area. This, in turn, emphasizes the need for more preventive measures to reduce the risk of zoonotic outbreaks.

One hundred and five (105) Camels were investigated at the Maiduguri abattoir, Nigeria using floatation and sedimentation techniques for helminth parasites and haematological indices with the microhaematocrit reader. Overall, prevalence of infection was 92.4% [(Coccidia (8.5%), Strongyloides (8.5%), Trichuris (11.4%), Ciliates (6.7%), Ascaris sp. (3.8%), Moniezia sp. (1.9%), Amphistome sp. (0.9%) and Balantidium sp. (0.9%)]. There was no significant difference between infected and non-infected camels for blood parameters. There is need to regularly deworm camels and further study the impact of helminthes in the camel especially with respect to its zoonotic potentials in countries with significant population of camels.

This study was conducted to determine the prevalence and effect of parasitic infection on erythrocyte indices in trade camels slaughtered in Maiduguri, Nigeria. Two hundred adult one humped camels comprised of 87 (43.5 %) males and 113 (56.5 %) females were examined for helminths and hemoparasites at their slaughter time according to the standard procedures. An overall prevalence of 79 % for single and mixed infections was observed. Examination of faecal samples from camels shows 82 (41 %) were harbouring different nematodes, mostly Strongyle, Strongyloides and Hemonchus species. Buffy coat and thin smear examination of blood samples showed Babesia and Anaplasma species. More females (44.5 %) than males (34.5 %) were positive for various parasitic infections. But the percentage was not statistically significant (P > 0.05). Packed cell volume (PCV), mean haemoglobin concentration (MCH), mean corpuscular haemoglobin concentration (MCHC) and red blood cell counts were significantly (P < 0.01) affected in the infected camels compared to the non-infected ones. Parasite infection in camels leads to macrocytic anaemia.

A feeding trial of 120 days duration was conducted to study the effect of replacing 20 and 25 % of camel ration by poultry litter (PL) on the performance and some blood biochemical parameters. Fifteen healthy one–humped camels were allotted into three groups (5 animals / group). The first group was fed a basal ration and considered as control, while the second and third groups were fed rations in which poultry litter replaced 20 and 25 % of the basal ration. There was no significant differences in the dry matter intake and digestion coefficients of dry matter and ether extract between the different groups and camels fed on ration containing poultry litter had significantly (P < 0.05) decreased daily gain and feed conversion compared to the control. The apparent digestibility of crude protein by camels increased with 20 % poultry litter in the ration compared with other treatments. Digestibility of crude fibre was higher in rations containing poultry litter compared to control one. No significant differences were observed in blood biochemical parameters except urea and uric acid concentrations were significantly (P < 0.05) higher in the serum of animals fed on poultry litter. In general, it could be concluded that, dried poultry litter can be utilized efficiently and safely in rations of camels up to a level of 25 % without adversely effect on performance.
