Ein Gentest für die GM1-Gangliosidose beim Alaskan Husky

Gegenstand und Ziel: Die GM1-Gangliosidose der Alaskan Huskies ist eine angeborene Erkrankung, die durch einen autosomal rezessiv vererbten Defekt des Gens für die saure β-Galaktosidase (GLB1) hervorgerufen wird. Klinisch zeigen die Tiere Minderwuchs sowie, beginnend im Alter von sechs bis acht Wochen, neurologische Ausfallerscheinungen wie Ataxie und Dysmetrie. Zur gezielten Vermeidung dieser Erkrankung ist es für Zuchtentscheidungen wichtig, Anlageträger für den Defekt sicher identifizieren zu können. Material und Methode: Die Spezifität und Sensitivität eines kürzlich beschriebenen Gentests zum direkten Nachweis des genetischen Defekts bei der GM1-Gangliosidose des Alaskan Husky wurde mit der biochemischen Bestimmung der enzymatischen Aktivität der β-Galaktosidase aus isolierten Hautfibroblasten, klinischen und pathologischen Befunden sowie einer Stammbaumanalyse verglichen. Ergebnisse: Die β-Galaktosidase- Enzymaktivitäten von Anlageträgern lagen im Durchschnitt niedriger als die Enzymaktivitäten homozygot gesunder Hunde. Da sich jedoch die Werte der beiden Gruppen überlappten, war eine sichere Identifizierung von Anlageträgern mit der biochemischen Analyse nicht möglich. Demgegenüber erlaubte der Gentest eine eindeutige Unterscheidung zwischen homozygot gesunden Tieren und Anlageträgern. Schlussfolgerung: Der Gentest ist der biochemischen Diagnostik überlegen. Klinische Relevanz: Mithilfe des Gentests können die phänotypisch unauffälligen Anlageträger sicher identifiziert werden. Damit lassen sich Anpaarungen von zwei Anlageträgern verhindern und das Auftreten der GM1-Gangliosidose kann zukünftig vermieden werden.

[Field validation of a real-time PCR test for the detection of Mycoplasma hyopneumoniae in nasal swabs of live pigs]

Enzootic pneumonia (EP) of pigs, caused by Mycoplasma hyopneumoniae has been a notifiable disease in Switzerland since May 2003. The diagnosis of EP has been based on multiple methods, including clinical, bacteriological and epidemiological findings as well as pathological examination of lungs (mosaic diagnosis). With the recent development of a real-time PCR (rtPCR) assay with 2 target sequences a new detection method for M. hyopneumoniae became available. This assay was tested for its applicability to nasal swab material from live animals. Pigs from 74 herds (average 10 pigs per herd) were tested. Using the mosaic diagnosis, 22 herds were classified as EP positive and 52 as EP negative. From the 730 collected swab samples we were able to demonstrate that the rtPCR test was 100% specific. In cases of cough the sensitivity on herd level of the rtPCR is 100%. On single animal level and in herds without cough the sensitivity was lower. In such cases, only a positive result would be proof for an infection with M. hyopneumoniae. Our study shows that the rtPCR on nasal swabs from live pigs allows a fast and accurate diagnosis in cases of suspected EP.

Does emergency vaccination make sense as a supporting element in control of foot-and-mouth disease in Switzerland

The outbreak of foot and mouth disease (FMD) in Great Britain in 2001 let to discussions and especially emergency vaccination was deemed as an alternative to the culling of vast numbers of healthy animals. The project emergency vaccination for FMD in Switzerland was conducted to compare the effectiveness of conventional control strategies during a FMD outbreak alone and with ring vaccination of 3 km and 10 km, respectively. The results of this project showed that emergency vaccination conducted at the beginning of an epidemic was not favorable compared to conventional disease control strategy in Switzerland. In case of an advanced FMD epidemic, a 10 km ring vaccination could support the disease control in a positive way. However, the goal of emergency vaccination to save animal live can hardly be achieved due to actual legal basis and the consequent restriction measures within vaccination zones which will lead to welfare culling.

Tierversuche: Wie viel Nutzen muss Forschung erbringen? : Sicherheitsrechtliche Implikationen der bundesgerichtlichen Bestätigung des Verbots von zwei Tierversuchen mit Rhesusaffen

Das Bundesgericht untersagte 2009 zwei Tierversuche der neurologischen Grundlagenforschung mit Rhesusaffen. Erstmalig wurden damit in der Schweiz umstrittene Tierversuche auf dem Rechtsweg verhindert. Das Gericht fordert für Tierversuche eine differenzierte Abwägung zwischen dem Erkenntnisgewinn und der Belastung der Tiere sowie eine Berücksichtigung ihrer entwicklungsmässigen Nähe zum Menschen. Der im August in der Zeitschrift Sicherheit & Recht (2/2010) erscheinende Beitrag gibt einen Überblick über die rechtlichen Rahmenbedingungen von Tierversuchen in der Schweiz, erläutert die Hintergründe der beiden Entscheide und zeigt ihre sicherheitsrechtlichen Implikationen auf.

Attitudes of Swiss veterinarians towards pain and analgesia in dogs and cats.

A survey was performed to evaluate the use of perioperative analgesia in dogs and cats by veterinary practitioners. Questions were grouped in seven sections recording personal data, education in veterinary analgesia, general ideology regarding treatment of perioperative pain, personal experience, assessment, and use of main analgesics to treat perioperative pain. A total of 258 received forms were analyzed. Based on 5 questions, 88 % showed excellent motivation to use perioperative pain therapy. The main reason declared for the use of analgesics was to relieve the patient from pain (64.1 %). Most veterinarians reported to routinely administer analgesics before (71 - 96 %) or after (2 - 23 %) surgery. The most used analgesics were non-steroidal anti-inflammatory drugs (carprofen, meloxicam) and opioids (butorphanol, buprenorphine). Animals were routinely evaluated for pain after recovery. Only 43.8 % of veterinarians declared to use loco-regional anaesthesia. Swiss veterinarians appear to recognize well the need for perioperative pain treatment. However, weakness was shown in evaluating pain severity, distinguishing between opioid classes, and using loco-regional anaesthesia.

First cases of besnoitiosis in cattle in Switzerland

Bovine besnoitiosis has been diagnosed in neighboring countries but not in Switzerland so far. This disease occurs endemically in France and focal outbreaks have been reported in Germany and Italy. To determine if Besnoitia besnoiti is introduced into Switzerland through the import of breeding cattle from France, a systematic serological survey was performed. A total of 412 breeding cattle (from 114 farms) imported from France into Switzerland between 2005 and 2011, were serologically examined for antibodies against B. besnoiti using a commercial ELISA kit (PrioCHECK© Besnoitia Ab 2.0, Prionics AG, Zurich, Switzerland). Sixty-four (15.5 %) animals reacted positive in ELISA. The serologic diagnosis was confirmed by an indirect immunfluorescence test (IFAT) and a Western blot (WB) in only 2 Limousin cows imported from France on a farm in Eastern Switzerland. Subsequently, this whole herd (n = 16) was examined clinically and serologically and 2 additional Limousin cows imported from Germany also reacted positive in the three serological tests. One of these cows presented B. besnoiti tissue cysts in the scleral conjunctiva and typical skin lesions in the head region. The infection was further confirmed cytologically, histopathologically and by PCR. It can be concluded that the parasite is most likely being introduced into Switzerland through the import of infected animals.
