Border disease (BD) is a congenital infection of sheep characterised by still-birth, abortion and the birth of weak lambs with nervous symptoms and sometimes an abnormally hairy birthcoat. The lambs are almost constantly trembling or shaking, they often have an erratic gait and in severe cases are unable to rise. The nervous signs are due to a defective myelinogensis of the central nervous system and tend to disappear at a later age. Many affected lambs die shortly after birth and those which survive usually show retarded growth. The disease is caused by a virus which is closely related to the virus of bovine virus diarrhoea (BVD). The virus may be isolated from every organ and is excreted with saliva, nasal discharge, urine and faeces. Clinically the diagnosis can be made with high probability when nervous signs and hairy birthcoat are both present. Laboratory diagnosis is based on the detection of antigen by immunofluorescence or virus isolation. In addition ewes of BD-affected lambs usually possess antibodies against BVD-virus. In some lambs, an immune response starts during prenatal life, others show a transient or lasting low level response at a later age, whereas still others remained serologically negative for at least 2 1/2 years. Asymptomatic virus carriers occur among lambs as well as among adult sheep. The persistently infected animals are continously shedding virus and thus maintain the infection in the flock.

A repeated dose toxicity study of montirelin hydrate (NS-3), a new drug for the treatment of disturbance of consciousness, was conducted in beagle dogs. Male and female dogs were given the drug intravenously for 26 weeks at doses of 0 (control), 0.02, 0.2, 2 and 20 mg/kg. After discontinuation of the treatment, a 9-week recovery test was also conducted. No deaths related to the treatment were observed. Nasal discharge in all dose groups, and tremor, salivation and emesis in the 0.2 mg/kg group and over were seen. Decrease in body weight gain was observed in the 2 and 20 mg/kg groups. There were no abnormalities in body temperature, and food and water consumptions. Urinalysis and electrocardiographic, ophthalmoscopic and hematologic examinations failed to show any abnormalities attributable to the treatment. In blood chemical examination, increase in T3 level was observed in the 2 and 20 mg/kg groups of females. There were no pathological findings attributable to the treatment. The changes mentioned above were satisfactorily reversible. The nasal discharge seen in the 0.02 mg/kg group was considered to be of no toxicological significance. These results show that the NOAEL of montirelin hydrate is 0.02 mg/kg for 26-week repeated dose toxicity in dogs.

Clinical and pathologic findings of avian paramyxovirus type 1 (PMV-1) in 19 houbara bustards (Chlamydotis undulata macqueenii) imported from Pakistan into the United Arab Emirates and one captive-bred bird are reported. Clinical signs included circling, walking backward, ataxia, opisthotonos, torticollis, recumbency, head tilt, head shaking, head tremor, tucking of head under keel, nasal discharge, conjunctivitis, and diarrhea. The length of time imported birds exhibited clinical signs varied from 4 days to 18 mo after importation. Hemagglutinating antibodies against PMV-1 were detected in the sera of all 17 birds from which blood samples were collected, and PMV-1 was isolated from pooled brain, spleen, and lung tissues from two birds with acute clinical signs. There were no distinctive gross lesions at necropsy, and histologic findings were consistent with but not pathognomonic for PMV-1. All houbara bustards managed in a captive breeding and restoration program established by the National Avian Research Center have been vaccinated against PMV-1 since October 1992, and no case of PMV-1 has been reported in this collection since that time.

Four Merino lambs were intranasally inoculated with bovine herpesvirus type 5 (BHV-5) reference strain N569. Two lambs were mock-inoculated as negative controls. The virus-inoculated animals developed apathy, inappetence, rhinitis, nasal, ocular and genital discharge, slight diarrhea and neurological disorders, like tremor and salivation. BHV-5 was isolated from the nasal discharge in two of the animals, while the polymerase chain reaction (PCR) detected the virus in all the infected lambs. Two lambs died on post infection day (PID) 13, while the other two infected animals were euthanized on PID 15 and 30. Gross pathological changes were not observed, however, histopathological examinations revealed diffuse nonsuppurative meningo-encephalitis in all infected animals. Viral antigen was detected by immunohistochemistry and viral nucleic acid was revealed by in situ hybridization in the brain of the two lambs, which died on PID 13. The virus was demonstrated by virus isolation and by PCR from different organs of all the infected animals. Slight rise of antibodies was observed in the infected animals from PID 15. The results show that BHV-5 is able to cross the species barrier and may establish infection in sheep.

We report clinical and pathological features of enzootic nasal adenocarcinoma (ENA) in one sheep in Algeria. A one-year-old Ouled Djellal sheep from a large herd (~1240 animals), located in Bordj Bou Arreridj, Algeria, was clinically diagnosed by the presence of persistent seromucous nasal discharge, head shaking, muzzle licking, dyspnoea, exophthalmia and frontal protrusion. The sheep was euthanized, and the necropsy was performed. Gross examination showed soft touch, pinkish-white tumour masses in the nasal cavities with distortion of the turbinates and of the medium septum. According to clinical and pathological findings, the tumour has been defined as a low grade mixed nasal adenocarcinoma, with the presence of tubular and papillary structures. This is, to our knowledge, the first report of ENA in Algeria known to be associated with enzootic nasal tumour virus (ENTV) infection. However, such association requires confirmation by direct and/or indirect viral investigation.
