The development of the Purkinje fibre (PF) of the camel foetus was studied in dromedary camel foetuses during the three gestational periods. A total of 30 hearts were used, the hearts were collected from Tamboul and Al-Salam slaughterhouses, Sudan. The samples were prepared by routine histological procedures and stained by the general histological stain (H&E) and special stains. In the first trimester PF were embedded in cardiac muscle fibres close to the ventricular endocardium. In second trimester, some of PF were embedded in the connective tissue, some fibres contained two nuclei. The striation was clear in peripheral parts of some fibres. At 178 second trimester days of gestation most of fibres contained two nuclei and the cytoplasm around the nuclei was light. At the third trimester PF appeared as bundles of fibres parallel to myocardial muscles. They were also embedded in the endocardial connective tissue as groups or separate fibre. They were embedded in the myocardium in the first trimester and either between the endocardium and myocardium or within the myocardium in the second and third trimesters. It was concluded that most of Purkinje fibres were not found in their normal location till the last stages of pregnancy, which means that PF continue their developmental changes after birth.

M. Respiratory diseases of camel especially pneumonia continue to be a major problem commonly encountered in camel. In this study, 45 pneumonic lungs from one humped camels with different sex and ages ranging from six months to 15 years and originated from different states of the Sudan including Kassala, Al Gedarif, Kordofan and Darfur these were subjected to isolation, identification of bacteria and determination of the pathological changes. The isolates were then fully confirmed by biochemical identification using conventional and automated techniques including API kits and automated system Vitek2 Compact. 80 bacterial isolates were recovered, they were: 15 (18.75%) S. aureus, 7 (8.75%) S. epidermedius, 5 (6.25%) S. warrner, 1 (1.25%) S. heamolyticus, 6(7.5%) Str. pneumonia, 5(6.25%) Str. pyogenes, 1(1.25%) Str. suis 11(13.75) E. coli, 3(3.75%) Coryneulcerans, 1(1.25%) C. amycolatum, 1(1.25%) Actinomyces naeslandii, Actinomyces pyogenes, 9(11.25%) K. pneumonia, 7(8.75%) Ps. aeruginosa, 2(2.5%) Aeromonas salmonicida, 1(1.25%) Burkhorder iacepacia, 2(2.5%) Bacillus spp and 1(1, 25%) Flacklamia homonis. The histopathological changes were emphysema with an incidence of 25 (55.6%), atelectasis in 24 (53.3%), haemorrhge in 20 (44.4%), oedema in 19 (42.2%) , inflammatory changes represented by fibrinous pneumonia in 25 (55.6%), purulent bronchopneumonia in 13 (28.9%), Aspiration pneumonia in 10 (22.2%), interstitial pneumonia 9 (20%) and abscesses in 4 (8.9%) and Tumors in 3 (6.7%). Pneumonia is known in camel as complex multifactorial disease in which bacterial, viral, mycoplasma and fungal infections combine with other predisposing factors such as rearing systems, stress factors, climatic changes, and unhygienic conditions. Identification of the pneumonic pathogens in the present work cleared that Staph. aureus, was the most pneumonic bacteria isolated from lung tissue at rate of 18.75% Article 2017-01-10T00:00:00Z https://repository.sustech.edu/handle/123456789/20007 Cavernous Haemangioma in the Liver of One Humped Camels (Camelus Dromaderius) In the Sudan: A Case Report Mohammed, Nuseba H.; Osman, Halima M. The present communication described two cases of cavernous haemangioma in the liver of one humped camels (Camelus dromaderius) in the Sudan. Two samples were diagnosed in a (four year old camel from Kassala and 13years old camel from West Sudan) female camel. Physical examination of the liver revealed small erythematous papules on the liver surface. Microscopical examination of the liver revealed dilated, irregular vascular spaces lined by single layer of endothelial cells supported by fibrous septa and showing numerous papillary enfolding. The line of demarcation between the tumor and normal hepatic tissue was well defined the normal hepatic parenchyma atrophic and an irregular or spongy interface with an ill-defined margin.

In this study, a questionnaire was designed to investigate camel herd composition and estimation of milk yield of shecamels in different age groups and in different seasons under traditional production system. The collected data were analyzed by using descriptive statistics. The result of the study showed that, the percentages of the herd structure decreased as the camels age group increased, they were 13.1%, 13.4%, 11.6%, 10.2%, 9.6%, 8.5%, 7.2%, 7.2%, 6.3%, 6.3% and 6.7 % for age groups less than year, 2years, 3 years, 4 years, 5years, 6years, 7 years, 8 years, 9 years, 10 years and more than 11 years respectively. The study showed that Waddan area was recorded higher percentages than the other areas in herd structure for first age and second group. In the third group (3 years ) there were variations in the herd structures, Soukana was the least percentage in herd structure and Hun was the highist. In the age groups between 7 to 11 years there were variations in the structure in Algufra. Article 2017-01-10T00:00:00Z
