Sheep persistently infected with Border disease readily transmit virus to calves seronegative to BVD virus.

Bovine viral diarrhea- and Border disease viruses of sheep belong to the highly diverse genus pestivirus of the Flaviviridae. Ruminant pestiviruses may infect a wide range of domestic and wild cloven-hooved mammals (artiodactyla). Due to its economic importance, programs to eradicate bovine viral diarrhea are a high priority in the cattle industry. By contrast, Border disease is not a target of eradication, although the Border disease virus is known to be capable of also infecting cattle. In this work, we compared single dose experimental inoculation of calves with Border disease virus with co-mingling of calves with sheep persistently infected with this virus. As indicated by seroconversion, infection was achieved only in one out of seven calves with a dose of Border disease virus that was previously shown to be successful in calves inoculated with BVD virus. By contrast, all calves kept together with persistently infected sheep readily became infected with Border disease virus. The ease of viral transmission from sheep to cattle and the antigenic similarity of bovine and ovine pestiviruses may become a problem for demonstrating freedom of BVD by serology in the cattle population.

[Severe inflammation of the muzzle caused by a nose ring in a breeding bull]. / Schwere Flotzmaulentzündung infolge Nasenrings bei einem Zuchtstier.

This report describes the findings in a bull with severe inflammation of the muzzle and nose attributable to a nose ring. The most striking finding was that the bull continually licked the right side of the upper lip. The muzzle and right upper lip were swollen, hard, reddened and partially depigmented. Mucopurulent nasal discharge and salivation were also noted, and palpation of the right upper lip was extremely painful. Based on the findings, purulent infection of the right side of the muzzle, right naris and external nasal passage was diagnosed. After removing the nose ring the affected areas were washed daily for four days with a camomile-containing solution after which a chlorhexidine and dexpanthenol salve was applied. The bull also received ceftiofur and ketoprofen. The general condition and appetite of the bull normalised within a few days, and the inflammatory lesions resolved with the exception of the areas of depigmentation. After ten days of treatment, the bull was considered healthy and discharged from the clinic.

Sonographic findings in an alpaca with Mycobacterium kansasii infection.

This case report describes the clinical, ultrasonographic and postmortem findings in an alpaca with Mycobacterium kansasii infection. The alpaca was referred because of chronic weight loss and weakness. The results of clinical examination, haematology and serum biochemistry were not diagnostic. Ultrasonography of the liver revealed multiple, hyperechogenic lesions with a diameter of 1 to 3 cm. Histological evaluation of a liver biopsy sample showed acute, multifocal, suppurative, necrotising hepatitis. Despite treatment with antibiotics, the alpaca died. Postmortem examination revealed nodular to coalescing lesions in the liver, lungs, mediastinum, pleura and greater omentum, which could not be differentiated macroscopically or histologically from lesions caused by tuberculosis. Ziehl-Neelsen staining showed massive numbers of rods within epithelioid macrophages, which were identified as Mycobacterium kansasii by polymerase chain reaction analysis.

An unusual cause of traumatic reticulitis/reticuloperitonitis in a herd of Swiss dairy cows nearby an airport.

This report describes the findings in five cows from one dairy herd, in which all 31 cows were slaughtered or euthanised because of traumatic reticuloperitonitis. All the cows had numerous thin sharp pieces of metal attached to a magnet in the reticulum, giving the magnet a hedgehog-like appearance. Investigation revealed that the cattle had eaten forage harvested from a field immediately adjacent to an airport. The snow was cleared from the airport runways with a machine that had a wire-bristle brush attachment. Mechanical wear resulted in numerous wire bristles breaking and these were blown with the snow onto the field in question. The wire then became accidentally incorporated into the hay and grass silage at harvest the next summer and was ingested by the cattle in the fall and winter. To prevent further cases, approximately 200 tonnes of hay and grass silage contaminated with wire were discarded and 30 hectares of the 50-hectare field were cultivated and re-sown. The wire-bristles of the snow plow were replaced with plastic bristles. The cost of this and the livestock loss was several hundred thousand Swiss Francs.

Comparing satisfaction levels of inpatients and outpatients with a diabetes teaching program.

With the changing climate of health care there is an increasing need to offer diabetes education in outpatient rather than inpatient settings. This study was conducted to determine if there is a significant difference in the satisfaction level between inpatients and outpatients receiving diabetes teaching in the same program. Patient satisfaction with the practitioner is a determinant of patient learning and compliance. The study included 42 inpatients and 47 outpatients who participated in the same program and were taught by the same teaching nurses and dietitians. A questionnaire developed for this study examined six areas: (1) demographics; (2) patients' perception of understanding their diabetic condition and treatment; (3) comfort in class; (4) perception regarding treatment as an individual; (5) life satisfaction; and (6) influence of recommendations on future health. The results of the study showed a significant difference (P less than 0.05) in two areas: (1) inpatients felt that more interest and concern were shown towards them than outpatients and (2) more inpatients than outpatients felt they were treated more like individuals than cases. The results indicated that the personalized and ongoing contact inpatients have with the practitioner determine the degree of satisfaction with diabetes teaching received in these important areas.
