ABSTRACT
Hydrosalpinx is characterized by the accumulation of thin mucus within the lumen of the oviduct and it is rare in small ruminants. A5-year-old, horned, mixed breed doe with a history of infertility was necropsied for teaching purposes. Preslaughter examination revealed mucopurulent keratoconjunctivitis, rhinitis, synovitis and mastitis with watery purulent discharge from the mammary glands indicated mycoplasmal infection [agalactia]. At necropsy, the carcass was congested. The proximal portions of oviducts [Ampula] were distended, thin-walled and fluctuating in palpation. They were filled with clear thin mucus and were conic shaped, with 12 cm in length and 1.3 cm in width at the base and 0.5 cm at the top. The distal part of oviducts [Isthmus] was filled with semisolid purulent discharge causing total tube obstruction. The wall of the uterus and the uterine horns were thickened and mucosa was hyperplastic in appearance with small cysts which were measured at 0.3-0.5 cm. There was a slight fibrous adhesion between the mesosalpinx and the ovaries. The right ovary contained a corpus luteum, a large graafian follicle and numerous corpora albicans. Microscopically, atrophy of the wall of ampula, chronic inflammation of the isthmus and cystic endometrial hyperplasia was seen. Direct examinations and culture of the exudate showed mucus without any secondary infection. On the basis of macroscopic characteristics and laboratory findings, the condition was diagnosed as a bilateral hydrosalpinx due to obstruction of the distal part of the oviducts along with cystic endometrial hyperplasia

Leptospirosis is an important infectious disease of animals and humans caused by the pathogenic leptospires which are classified into one species of Leptospira interrogans containing over 212 serovars. This study was conducted to determine the prevalence of Leptospira-induced abortions in Tabriz [north-west of Iran] dairy herds and to determine the pathogenic Leptospira serovars responsible. From May 2008 through August 2010, 16 [21.05%] of 76 submissions [fetuses and placentas] to the Large Animal Clinic of the Veterinary Faculty at the University of Tabriz were diagnosed as positive to L. interrogans serovars by PCR
In contrast, only 9 [11.85%] of 76 dam's sera were diagnosed as positive to leptospirosis by the microscopic agglutination test [MAT]
Two out of 9 animals were seropositive to serovar pomona, one animal to serovar icterohaemorrhagiae, two animals to canicula, three animals to both pomona and grippotyphosa, and one animal to the both canicula and grippotyphos. Moreover, the prevalence of Leptospira-induced abortions was high in the aged cows and advanced pregnancies [7-9 months]
However statistical difference was not observed among these groups or different periods of pregnancy. In conclusion, serovar pomona induced abortions were determined to be more common leptospiral abortions in cattle in Tabriz and combination of PCR protocol with the MAT test would be more effective than the single test for etiological diagnosis of bovine abortions?
ABSTRACT
A Holstein heifer with symptoms of dystocia was admitted in the Large Animal Clinic at the University of Tabriz. In the vaginal examination, the fetus was found at posterior presentation and by doing some obstertrical maneuvers, a male calf was delivered. An interesting phenomenon was the presence of two skin sacs in dimensions of 12 x 12 cm and 12 x 18 cm at the right and left upper cervical regions, respectively; and also the heart beats under the neck skin at the lower cervical region. Due to severe dyspnea, after 2 min the calf died. At necropsy, the heart was located outside of the thoracic cavity, under the neck skin. The direction of the heart axis was reversed as the base was directed caudoventrally and the apex craniodorsally. Unlike a normal calf's heart, the shape of its apex was rounded like a dog heart. Histopathologic examination revealed severe congestion, edema and hemosiderosis in the lungs, passive venous congestion and scattered foci of cardiomyolysis in the myocardium. Based on anatomical and histopathological findings, the disorder was diagnosed as bovine fetal Ectopia cordis cervicalis associated with two cervical sacs
ABSTRACT
A five-year-old Holstein cow with a history of vaginal prolapse was admitted to the Large Animal Clinic, Faculty of Veterinary Medicine, University of Tabriz. According to the owner, she had a 5-month history of vaginal prolapse and frequent sanguineous discharge from the vagina. Appetite was normal and its last parturition was two months ago. Clinical examination revealed a tumor like mass that attached to the vaginal roof and partly protruded through the vagina without any vaginal prolapse. After epidural anesthesia, the mass was surgically removed with some of the surrounding tissue. The dimensions of the mass were 5.2 x 4 x 3.4 cm. Macroscopically, it was relatively well circumscribed with a lobulated and ulcerated surface. In cut section, the mass was homogenously creamy in color. There were no foci of necrosis or hemorrhage. Microscopically, the growth was composed of spindle-shaped flbroblastic type tumor cells that formed interlacing and intersecting bundles. The neoplastic cells showed pleomorphism, karyomegaly and slight nuclear hyperchromatism. The mitotic index was less than five. Based on the site, biological behavior, immunohistochemistry results, macroscopic and microscopic characteristics, the mass was diagnosed as a well-differentiated fibrosarcoma. This is the first report of cow vaginal fibrosarcoma from Iran
