Titel: 
A NATURALLY OCCURRING CASE OF EPIZOOTIC ENTEROPATHY IN A SPECIFIC-PATHOGEN-FREE RABBIT COLONY
Auteur(s): 
D. Vandekerchove, S. Roels, G. Charlier
Samenvatting: 
In 1996 and 1997 a new epizootic enteric rabbit disease appeared in Europe. Since then the disease has also been reported in other parts of the world. Its main symptoms are caused by paresis of the intestinal tract. The causative agent is still unknown. The disease has been reported in meat rabbits and does, as well as in pet rabbits. The present report concerns a naturally occurring case of this disease in a specific-pathogen-free (SPF) rabbit colony. In the intestinal contents of one animal sacrificed for thorough examination, rotavirus and an apathogenic type of Escherichia coli were detected. From the ileal wall Providencia rettgeri was isolated, which is unlikely, however, to be of pathogenic significance. Histological and electron-microscopical analyses did not reveal any pathognomonic lesions.

Neonatal death of a calf due to intra-abdominal blood loss from the umbilical arteries
Auteur(s): 
T. Vanholder, J.L.J. Govaere, J. Laureyns, A. de Kruif
Samenvatting: 
This case report discusses the perinatal death of a Belgian Blue and White calf due to an intra-abdominal haemorrhage after parturition. It was caused by persistent bleeding of the umbilical arteries. These arteries were retracted but did not show any constriction. Keywords: Calf - Perinatal Death - Umbilicus - Arteria Umbilicalis

INGUINAL HERNIA IN A GELDING
Auteur(s): 
L. Lefère, L. Vlaminck, P. Deprez
Samenvatting: 
This paper describes an inguinal hernia in a 12-year-old gelding. The cause of the symptoms was not detected during clinical examination and the diagnosis was made during surgery. Most probably, the rarity of the condition was the underlying reason for this diagnostic failure.

Titel: 
SPONGIFORM DEGENERATION OF THE WHITE MATTER IN THE CENTRAL NERVOUS SYSTEM OF AUSTRALIAN CATTLE DOG LITTERMATES
Auteur(s): 
H. De Bosschere, M. Bos, R. Ducatelle, S. Bhatti, L. Van Ham
Samenvatting: 
A spongiform degeneration of the white matter in 2 out of 8 Australian cattle dog littermates is described histologically. On the neurological examination, these dogs showed sternal decubitus, inability to walk and loss of coordination. A cerebellar ataxia was suspected. Microscopically, marked vacuolation of the white matter was observed in the cerebrum, cerebellum and dorsal funiculus of the spinal cord. A severe hypertrophy of astrocytes with pale and swollen nuclei and eosinophilic cytoplasm was also observed. This pathology has been described in several animals species but this is the first description in the Australian cattle dog.

INFILTRATIVE LIPOMA IN THE FORELEG OF A HORSE
Auteur(s): 
E. Ollé, J.H. Saunders, D. Desmecht
Samenvatting: 
This case report describes an infiltrative lipoma in a horse. A slow-growing mass, detected early after birth, was present at the caudal aspect of the foreleg (antebrachium) of a 2-year-old gelding. Cytological features were that of a benign lipoma. Surgical resection was attempted but failed due to the infiltrative nature of the mass. Consequently, the horse was euthanized. Histopathology revealed an infiltrative lipoma. This tumor is histologically benign but surgical resection is usually impossible due to its infiltrative nature.

TWO CASES OF LYMPHOID LEUCOSIS IN SNAKES
Auteur(s): 
F. Vercammen, R. De Deken, J. Brandt
Samenvatting: 
Two Yellow Anacondas (Eunectes notaeus) were diagnosed with lymphoid leucosis after a history of anorexia. One snake presented a large tumoral mass in the intestinal wall; the other had several smaller neoplasms in different organs. Reptilian tumors are being diagnosed more frequently in recent decades.

Titel: 
ENTEROCOCCUS CECORUM SEPTICEMIA AS A CAUSE OF BONE AND JOINT LESIONS RESULTING IN LAMENESS IN BROILER CHICKENS
Auteur(s): 
L.A. Devriese, K. Cauwerts, K. Hermans, A. M. Wood
Samenvatting: 
A severe outbreak of lameness with joint and bone lesions and evidence of bacterial infection due to Enterococcus cecorum was diagnosed on a Dutch broiler farm. Morbidity and mortality were as high as 10%, while the remaining chickens performed well. Bacterial chondronecrosis and osteomyelitis with loosening of the femoral heads (femoral head necrosis) in the end stage was the most frequently observed lesion. The same pathological process was seen, though rarely, in the T3/T4 spine articulation. Septicemia resulting in pericarditis, local myositis and, most prominently, bone and joint lesions, was the major diagnosis. E. cecorum could be isolated from nearly all lesions when appropriate isolation methods (blood agar incubated in a carbon dioxide-enriched atmosphere) were used.

UTERINE HEMATOMA IN A DOG
Auteur(s): 
H. De Bosschere, F. Van Steen, R. Ducatelle, E. Peeters, A. Daems
Samenvatting: 
A large intra-abdominal mass with several cavities was detected by ultrasound in a nine-year-old apathetic female German Shepherd with a very tense belly. At surgery, a fluctuating mass was found in the middle of the left uterine horn. Neoplasia was suspected and the mass was surgically removed. Histologically, a diagnosis of organizing hematoma was made.

Titel: 
FREEMARTINISM IN A SHEEP
Auteur(s): 
S. Verberckmoes, A. Van Soom, I. De Pauw, S. Van Cruchten, A. de Kruif
Samenvatting: 
In this case report an anatomical, histologic, hormonal and cytogenetic study of an intersexual sheep was carried out. At the age of 15 months, no udder could be detected in the animal, which had been classified as a female of a heterosexual twin at birth. At the age of 22 months the sheep was diagnosed as an intersex due to the presence of both male and female characteristics, viz. two testicles and a vulva. The hCG stimulation test proved that active Leydig cells were present in the male gonads. Histologic analysis after necropsy showed inflammation and atrophy of the testicular parenchyma. However, at the cytogenetic level, sexual chromosome mosaicism 54, XX / 54, XY was found after lymphocyte culture. These analyses made it clear that the intersex described here was a male pseudohermaphrodite. This condition occurs in less than 0.03% of the total sheep population. The hCG stimulation test can be used to distinguish “pseudo-male” from “pseudo-female” freemartins at a young age and without the need for necropsy.
