..In addition, caudal lung lobes were severely affected by a chronic partially obliterative bronchiolitis and peribronchiolitis with multifocal pleural involvement...

..Histopathological lesions were absent in this calf and antibodies against N. caninum were not detected in pleural fluid. Immunohistochemistry failed to demonstrate N. caninum antigen in all three calves...

..rectipeninus, remains difficult to explain. A chimeric origin is suggested despite the fact that microsatellite analysis of the animal's blood cells displayed no un- usual allele accumulation...

..Of the ten horses, seven survived by surgical or medical treatment. Beside of medical aspects, forensic aspects should be considered in such cases...

..Consequently, the use of rhG-CSF in the treatment of dogs with parvoviral enteritis cannot be recommended...

..Using the single parameter linear regression equation might be ideal for practical applications...

..However, parakeratosis could not be completely excluded as skin alterations were partly parakeratotic. On account of the close relationship between the two affected calves a genetic cause is likely for the present cases...

..Entamoeba (E.) histolytica is an obligate parasite of humans and non-human primates...

..Immunohistochemistry revealed strong expression of vimentin, and a variable labeling of factor VIII-related antigen, smooth muscle actin, and neurotrophin receptor p75. The final diagnosis was a primary meningeal hemangiosarcoma...

....

..The sequence of the P gene showed 97% identity with the Dutch virus isolated in 1988. There was 100% identity with the Dutch isolate from 2002 and a single nucleotide mismatch with the Danish isolate...

..The findings had many histological and immunohistochemical features in common with primary cutaneous ganglioneuromas in humans, enabling the canine tumours to be also classified as multiple cutaneous ganglioneuromas...

..The morphology of the tumour indicated a primary malignant peripheral nerve sheath tumour, resembling a neoplasm described in rats...

..Immunohistochemistry may be an additional useful method for diagnostic and research purposes in AHS...

....

..Therefore, the term spontaneous porcine motor neuron disease (SPMND) is proposed for this new and unique entitiy...

..Immunohistology is an additional method for identifying R. equi-infections in equine tissue and may be useful in retrospective studies on paraffin-embedded archive material...

..These results suggest that, in addition to oncosis, apoptotic cellular death in lymphatic tissues contributes substantially to the pathogenesis of rinderpest...

..Up-regulation of CD44 therefore appears to be associated with benign or relatively benign biological behaviour of canine mammary tumours...

..The basement membrane was disrupted focally, and single or clustered cytokeratin-positive epithelial cells were detected in the fibrous capsule, suggesting a possible transition to malignancy...

....

..This is the first report of a primary central nervous system lymphoma in an European roe deer...

....

..In addition, viral inclusion body diseases, like Avian Poxvirus, Psittacine Beak and Feather disease virus, Avian Adenovirus, Psittacine Herpesvirus and papillomavirus of psittacines are summarized and compared in the present article...

..Subacute to chronic changes were characterized predominantly by pyogranulomatous inflammations with extensive fibrosis. Adult parasites and eggs were detectable...

..Diagnosis requires endoscopic examination of the large bronchi. Early intraluminal stages can be treated transendoscopically...

..These findings suggest that endothelial cells, and to a lesser extent mononuclear cells, are the main target cells of AHSV infection during the late stage of the peracute form of the disease...

..This is the first report describing a diffuse, cerebral oligodendroglioma in a cow...

..Renal glomeruli were consistently negative for virus antigen whereas in interstitial infiltrates cells resembling macrophages stained positive for ADV structural proteins...

..The aberrant left subclavian artery did not significantly compromise the esophagus. Persistence of the right aortic arch is relatively rare in ruminants and has not previously been reported in a bison...

..The cause of the vascular lesions remains unknown. When compared with humans, atherosclerosis is rare in animals and has not been described in a walrus...

..At microbiological examination Aspergillus spp. were isolated. The present case indicates that mycotic pneumonia should to be considered as a differential diagnosis of pulmonary disorders in elephants...

..The yeast-like fungi were identified in tissue sections using histological and immunohistological methods...

..Reported cases are often linked to sadism and often lead to the animal's death. Veterinarians should keep in mind animal sexual abuse as a differential diagnosis in cases of anogenital injuries of unknown origin...

..Although the immunohistological findings are characteristic for immunological tolerance and viral persistence, viable offspring persistently infected with pestivirus was not observed...

..A fragment of the adenoviral polymerase gene was amplified, sequenced and compared with other reptilian adenoviral sequences...

..The role of environmental contaminants and their potential impact on immune function are discussed. The duration and geographical patterns of the two PDV epidemics are compared...

..This rare malformation in horses may be caused by absent or defective fusion of vertebral bodies leading to herniation of the spinal cord and meninges with subsequent degenerative alterations of the spinal cord...

..Pictures of imported endurance horses infected with glanders taken during an eradication campaign in Dubai, United Arab Emirates, in 2004 illustrate most typical clinical findings...

..This case report underlines risks caused by feeding of plants originally not destined as forage, if their active ingredients and effects are unknown or remain unconsidered...

..Own clinical and pathomorphological findings are described in an eight years old cow with a benign SCHWANNoma of the eight spinal nerve...

..Teratogenic pestiviruses were not found by serological, molecular or immunohistological methods. A causal relationship between the malformations and the bluetongue serotype 8 epidemic in 2007 has to be considered...

..An inbreeding coefficient of 3.168% for the malformed calf and the exclusion of environmental causes for these malformations of the eyes let us suppose a hereditary problem...

..A significant alteration of fibrin generation induced by FDPs may not occur until the serum FDP concentration exceeds 60 mg/l...

..Macroscopically and histologically, all 3 equine cases displayed great similarities to cementomas in other species. However, due to their high degree of differentiation, hypercementosis must be considered as a differential diagnosis...
