Subclinical laminitis in captive female Esfahan mouflon [Ovis orientalis isphahanica]: gross and light microscopic pathology

The herd consisted of 25 captive Esfahan mouflons and their offspring. The mouflons were wild and originated from their natural habitat in Esfahan province. They had been kept in small enclosures with rough concrete floors. The diet consisted of alfalfa hay, corn silage, and a commercial concentrate. The mouflons showed severe claw overgrowth and detectable subclinical form of laminitis such as sole hemorrhage and yellow wax discoloration. Both prevalences were unexpectedly high [73.9%]. The majority of foot lesion samples included in this study were taken from mouflons examined in the course of veterinary practice over a period of 4 months in a farm for clinical and histopathological purposes. Pseudocarcinomatous epidermal hyperplasia which are characterized by extreme proliferation of epithelial cells with large amounts of whorl-like structures that show no specific pattern, like dyskeratosis or central keratinization. Our findings were supportive of researchers who have suggested that subclinical laminitis is a multifactorial disease that involves a complex interaction between nutrition and management. Feeding management, proper design of facilities and routine trimming seems to prevent subclinical laminitis is predisposed for more serious lesions in Esfahan mouflons

[Clinical and pathological findings in a suspected cat to feline infectious peritonitis]

To study probability of occurrence of infectious peritonitis in a affected cat with severe ascite. Case study. A five months old male domestic short hair cat. In the first step, clinical examination, radiology and sonography interpretation, CBC, serum biochemical analysis and electrophoresis were done. After then abdominocyntesis was done and total protein and the ratio of albumin to globulin of the abdominal effusion was measured. Post mortem examination and histopahtological survey was done on tissue samples. In clinical examination mild pyrexia [40[degree sign] C], pale mucous membrane, anorexia and severe abdominal distention were revealed. The abdominal effusion was clear, straw colored, viscose and foamy in shaking. Radiology and sonography revealed severe distention of abdominal cavity was due to acsite. In necropsy, there was straw colored inflammatory exudates with diffuse granular fibrinous exudation covering serosal surfaces of intestine or floating in the abdominal effusion. Histopathological findings showed lymphocytic-plasmocytic infiltration and focal necrosis in-brain, heart, liver, kidneys, mesenteric lymph nodes and intestines. Failure of treatments of abdominal effusion [high levels of total protein decrease in albumin to globulin ratio and cytological status], characteristics of abdominal effusion, serum electrophoretic findings in accordance with clinical and histopathological findings made diagnosis

Case report: Lipoma in a budgerigar [Melopisittacus undulates]

To determine the identity and the cause ofmasses infiltrated in the most part of the body of abudgerigar. Case report. A pair of budgerigars [Melopisittacus undulates], living together and using the same diet for 4years, were presented to the Birds Clinic of PoultryDiseases Section, Department of Clinical Sciences, Facultyof Veterinary Medicine, University of Tehran. Clinical examination, radiography, necropsy,gross and histopathological observations. The male bird had no obvious health problem butthe female one demonstrated dyspnea, abnormal growth ofthe beak and the presence of hard and elevated masses inthe thoracic and abdominal area. Radiography revealed thepresence of masses infiltrated in the most part of the bodyand in particular at the opening of the thoracic andabdominal cavities. Due to critical condition of the femalebird and at its owner consent, the bird was euthanatized andnecropsied. Yellow-colored masses with a relatively hardstructure at the opening of the thoracic and abdominalcavities and soft fat tissues in the other parts of the body [including underarm and inguinal area] were observed innecropsy. Histological examination of the masses wasdiagnosed as lipoma
