Abstract. A benign cartilaginous tumor, chondroma, occurred in a 3.5 year-old ewe that was presented to the Veterinary Teaching Hospital, College of Agriculture and Veterinary Medicine, Qassim University. The tumor mass was in the form of a massive hard swelling at the right shoulder region. The ewe was not able to bear weight on the right forelimb that was abducted laterally. Exploration of that swelling revealed blood tinged serous fluid. The ewe was euthanized on owner’s request. At necropsy, the swelling measured approximately 53cm in length, 37cm in width and 25cm in depth and extending from the right forelimb to the thoracic cage. The contoured borders were covered by fibrous tissue capsule and the tumor was difficult to cut through. On cut surface, the tumor was yellowish in color with small cartilaginous multilobular structure and contained one compartment filled with blood tinged serous fluid. The case was diagnosed histopathologically as a chondroma.

This study was undertaken to verify the clinical signs, incidence, location, etiology and pathology of ovarian hydrobursitis in infertile female camels and estimate the fertility after unilateral surgical ablation. Genital organs (n
124) were examined in camels slaughtered at Makkah abattoir during Hajj of 2009. Infertile female camels (n
142) presented for management to the Veterinary Teaching Hospital, Qassim University, Saudi Arabia, were clinically examined and ultrasound-scanned for the diagnosis of genital abnormalities. Twenty eight camels diagnosed with ovarian hydrobursitis were further investigated for the effect of unilateral surgical ablation on breeding outcomes. Surgical ablation was carried on 14 cases (treated group), the remaining 14 cases were followed as controls (control group). Both groups were observed for breeding results: 90 days non-return rate (90d NRR) and calving rate (CR). Removed bursae were sent to the laboratory for histopathological investigation. Results showed that the incidence of ovarian hydrobursitis was 6.5% in slaughtered camels and 33.8% in infertile females. Camels with hydrobursitis were concurrently affected with pyometra, uterine and vaginal adhesions or purulent endometritis. Histopathology reported degeneration and hyperplasia of the lining epithelium, mononuclear cells infiltration, focal aggregation of inflammatory cells, cystic dilatation of multi-acinal structures, tiny hemorrhages, and presence of hemosiderin-laden macrophages. The 90d NRR and CR of the surgically-treated cases were 64.3% and 50%, respectively. None of the untreated cases conceived. These results confirmed that ovarian hydrobursitis causes infertility in dromedary female camels and is associated with inflammatory genital conditions and surgical ablation in unilaterally affected animals presents a potential treatment.

The objectives of this study were to describe the topographical anatomy of the pudendal nerve and to develop techniques of its blocking in adult male dromedary camels. Two cadavers and 30 adult male dromedary camels were used for the description of topographical anatomy and pudendal nerve block techniques, respectively. Results revealed that the pudendal nerve arises from the ventral branches of the 2nd and 3rd sacral spinal nerves. The nerve had three divisions; dorsal, middle, and ventral. The caudal rectal nerve was a branch of the dorsal division. Three blocking techniques were developed according to the results of topographical anatomy. The first technique was 15 cm cranial to the tail base and 7 cm lateral to the midline. The second was 12 cm cranial to the tail base and 7 cm lateral to the midline. The third was about 3 cm on either sides of the anus. Details and complications of each technique were reported. In conclusion, the anatomy of the pudendal nerve was different from that of cattle and horse. The second technique (12 cm cranial to the tail base and 7 cm lateral to the midline) for pudendal nerve block was superior among the three methods. Duration of nerve blocking was suitable for examination and for performing some surgical procedures in male dromedary camels.

In the present study, 37 buffalo from different localities in Upper Egypt were sampled and examined for Theileria spp. infection using Giemsa blood smears, conventional and nested polymerase chain reaction. The analysis targeted the 18S srDNA gene followed by sequencing and phylogenetic analysis using neighbor-joining (NJ) method. The study came up with the conclusion that Egyptian buffalos (Bubalus bubalis) infected with three Theileria (T. uilenbergi (13.5%), T. lestoquardi (2.7%) and T. ovis (2.7%)) small ruminants species rather than Theileria annulata (32.4%).

Histological examination of the peripheral circulation of the ovary of 18 females of the one-humped camel revealed a series of blood vessels with special structures. Throttle or occlusive artery was recorded in the ovarian zona vasculosa and in the cortex, and it showed an intimal cushion-like thickening made up of intimal bolsters that formed of smooth muscle fibres and glomus cells. The smooth muscle cells of the tunica media and the tunica adventitia of throttle artery pursued a circumferential pattern. Anastomosis arteriovenosa included simple bridge-like anastomotic vessels between arteria and venae, and glomus vessels of typical structure were demonstrated. Glomus organs were recorded in the ovary and were comprised of the tortuous glomus vessels and the related afferent and efferent vessels. Glomus cell complexes also were commonly occur at the cortex ovarii that possessed an extremely convoluted course with a hyperplastic wall and a narrow lumen. Atypical glomus vessels were demonstrated within the ovarian zona vasculosa, and the wall of these vessels was relatively thick and consisted of double tunica media with an intimal bolster. Some vessels contained an intimal bolster device of exclusively glomus cell structure (glomus bolster) with a tunica elastic interna demarcated it from the glomus cell media. Some venae represented several layers of longitudinally arranged smooth muscle fibres in the tunica media. Other venae showed wall with variable thickness. Venae with double muscular tunica media were recorded in the medulla. Some venae showed double internal elastic lamina. Also, venae with thick adventitia contained dispersed smooth muscle fibres were determined. Spirally oriented arteriole and venule were demonstrated within the cortex and medulla ovarii. Gestation sclerosis was demonstrated in ovarian zona vasculosa of pregnant females.

Objective: To report the causes and classification of mandibular fractures in dromedary camels and outcome after treatment. Animals: Single-humped camels (n = 116) with mandibular fracture. Methods: At admission, cause, site, classification, and radiography of mandibular fractures were recorded. Factors affecting fracture healing were analyzed. Results: Biting was the main cause of mandibular fractures in camels, which occurred more commonly in older males (P=.001) than in females. Open fractures were more common than closed ones (92.2% versus 7.8%, P = .0001) and single fractures were more frequent (82%) thanmultiple and comminuted fractures (18%; P = .001). Fractures were treated by interdental wiring (91.2%) or U-shaped aluminum bar (8.8%) and healing occurred in most (83.2%) fractures. Conclusions: In dromedary camels,mandibular fracture is most commonly caused by bites and can be successfully repaired by interdentalwiring or a U-bar technique with good outcome.

Th e objectives were to study the frequencies and classifi cation of fractures in young camels and to evaluate the clinical relevance of external fi xation as a method of treatment. Cases of fractures (n = 75) in young camels (less than 2 years old) were studied. On admission, the cause, site, classifi cation, and radiography of the fractures as well as the methods of treatment were investigated. Factors aff ecting fracture healing aft er treatment were investigated and analyzed. Th e frequencies of fracture were aff ected by breed (P = 0.001) and age (P = 0.01) but not sex. Trauma was the most common cause of fractures (P = 0.001). Tibial fracture was the most common. Treatment was performed either by plaster of paris bandage alone (82.1%) or in combination with polyvinylchloride (PVC) splints (70.6%), interdental wiring (14.8%), or 2 Steinmann pins (1.9%). Satisfactory healing was recorded in 81.5% of the treated cases. In conclusion, breed and age aff ected the frequencies of fracture. Th ere was a signifi cant eff ect of camel age on the cause of fracture. Moreover, there was a signifi cant eff ect of camel age on the fractured bone.
