Title: Pathological Disorders of the Female Reproductive System in Camels (Camelus dromedarius) in Tamboul Area, Sudan.
Author: Khalil, Nasar Eldien ALtaib Hussein
Abstract: This study was carried out to investigate the different reproductive disorders in female camels in Tamboul area. The study was divided into two parts; the first was a field survey in which a questionnaire was designed to collect data on mastitis and abortion. Ten herds with a total population of 1649 female camels were used during summer, winter and autumn for one year..In the slaughterhouse study, samples collected from genitalia of 2158 female camels at different ages of Arabi breed were examined. Gross lesions of affected organs were recorded. Representative samples from the gross lesions were fixed, processed, sectioned and stained with Haematoxylin and Eosin for histopathological examinations. Tissue samples and swabs from specific lesions in infected organs (ovaries, uterine tube, uterus, cervix, vagina and udder) were taken for bacteriological examination. The results showed that prevalence of clinical mastitis as calculated from the questionnaire results was 18.98% (acute 6.9%chronic 12% and gangrenous 0,061%).The incidence of abortion was (8.98%) of the examined female camels. Slaughter house results showed that 258 organs were affected representing 12% of the total number of camels investigated. The various pathological lesions and conditions included, uterine haemorrhage (19.38%), uterine congestion (17.05%), uterine white purulent spots (13.95%), uterine thickening and corrugation (7.75%), ovarian cysts (6.98%), pyometra (4.65%), vaginal prolapse (3.88%), ovarian hypoplasia (3.88%), uterine abscess (3.10%), vaginal necrosis (2.32%), cervical abscess (2.32%), uterine necrosis (2.32%), ovarian oedema and enlargement (2.32%), ovarian fibrosis (1.55%), uterine prolapse (1.55%), vaginal abscess (1.55%), uterine atrophy (1.16%), oophoritis (0.78%), uterine oedema (0.78%), uterine fibrosis (0.78%), cervical oedema (0.78%), thickening and corrugation in uterine tubes containing pus (0.78%) and hair in ovaries (teratoma) (0.39%). With regard to the udder, the main pathological lesions diagnosed were 353 representing 16.36% of the total animals examined. The main changes were chronic mastitis (66.29%), acute mastitis (31.73%), abscess (1.70%) and gangrenous mastitis (0.28%). Bacteriological examination revealed 98 isolates which consisted of 85 Gram-positive isolates (86.73%) and 13 Gram-negative ones (13.27%).The percentage of isolates in order of frequency were; Staphylococcus spp. (46.94%), Streptococcus spp. (18.37%), Bacillus spp. (13.27%), Micrococcus spp. (4.08%) and Corynebacterium spp. (4.08%). The Gram-negative bacteria isolates were; Escherichia coli (8.16%), Pseudomonas spp. (4.0%) and Salmonella typhimurium (1.02%). It was recommended that further studies are needed to ascertain the clinical aspects of these conditions and define their role as causes of reduced productivity and reproduction in female camels. Further studies on the etiological factors and pathological changes in aborted foeti are highly recommended
