Zusammenfassung Gegenstand und Ziel: Diagnostische Abklärung von Lähmungserscheinungen, die vereinzelt bei Mastschweinen bis 60 kg in einem Bestand mit 900 Mastplätzen auftraten. Material und Methoden: Ein männlich-kastrierter Mastläufer aus dem Bestand wurde in die Klinik für Schweine der Ludwig-Maximilians-Universität München eingeliefert und klinisch, labordiagnostisch und pathologisch- anatomisch untersucht. Ergebnisse: Der schlecht genährte Läufer befand sich in rechter Seitenlage mit Kopfschiefhaltung nach rechts. Er hatte kein Stehvermögen und Gehversuche waren auch mit Unterstützung nicht möglich. Die neurologische Untersuchung ergab einen normalen Analreflex, normale After- und Zwischenklauenreflexe an allen vier Gliedmaßen sowie eine erhaltene Hautsensibilität. Der Kornealreflex des rechten Auges war erloschen. Die serologische Untersuchung lieferte keine Hinweise auf Aujeszky‘sche Krankheit (AK), Klassische Schweinepest (KSP) und Leptospira spp. Die Werte der hämatologischen und klinisch-chemischen Parameter lagen im Referenzbereich. Pathologisch-anatomisch wurde eine rechtsseitige Hirnstamm-Meningoenzephalitis mit Isolierung von Arcanobacterium pyogenes nachgewiesen. Der neuropathologische Befund ergab als Ursache für die Meningoenzephalitis eine Zahnfach- und Kieferhöhlenentzündung mit Ausbreitung über den Nervus maxillaris. Schlussfolgerung und klinische Relevanz: Als Ursache für Lähmungen der Gliedmaßen bei Läufern sollten auch aufsteigende Zahnfachentzündungen durch Zahnfrakturen oder falsch durchgeführte zootechnische Maßnahmen (Zähnezwicken) in Betracht gezogen werden.

Ovine ulcerative balanitis and vulvitis in sheep of the Dorper breed has been observed in South Africa since 1979. Its aetiology has not been conclusively resolved, and there is some discrepancy in descriptions of its clinical features. In order to identify the pathogenic microorganism / s that contribute to the occurrence of the disease, the microflora in the genital tracts of both clinically healthy and affected sheep were isolated and compared. Bacteriological examination of materials from affected and unaffected sheep resulted in the isolation of Arcanobacterium pyogenes from 44.2 % and 17.2 % of them respectively. This difference is statistically significant (P < 0.01). Seventy-four per cent of the isolates originated from severe clinical cases. Mycoplasmas were isolated from 49.3 % of 116 clinically normal sheep and 78.2%of 104 affected sheep. There were significant differences in their rates of isolation in clinical groups (P < 0.05). Of all the mycoplasma isolates, Mycoplasma mycoides mycoides large colony variant (MmmLC) was isolated from 61.5 % of clinically diseased sheep while 6.0 % of the isolates were from apparently healthy animals (P < 0.05). The study threw light on the prevalence of mycoplasmas in the genital tract of apparently healthy sheep and, at the same time the identity of the mycoplasma pathogen associated with ulcerative balanitis and vulvitis was revealed. The findings of this investigation therefore confirmed the involvement of mycoplasma, particularly that of MmmLC large colony, in the disease in Dorper sheep in South Africa, and it was concluded that this microorganism is an important pathogen of balanitis and vulvitis in them. The study furthermore demonstrated a probable synergism between A. pyogenes and MmmLC. Finding these 2 organisms together occurred 53.4 times more frequently in the affected sheep than in the unaffected, which emphasises the probable multifactorial nature of the disease. The association between age and the presence of clinical signs was statistically significant. It was found that young sheep were more likely to have lesions than adult sheep. Clinical observations showed that the typical ulceration appears to be confined to the glans penis and lips of the vulva; no ulceration was observed on the shaft of the penis and prepuce or vaginal vestibule. In uncomplicated cases inflammation of the prepuce and vaginal vestibule is not a regular feature of the disease. Therefore the names ulcerative balanitis and vulvitis most accurately describe the nature of the disease in South Africa.

Arcanobacterium Pyogenes

Trueperella is a harmless bacterium in intestinal tracts of ruminants like deer, cattle, and pigs, but if it migrates out of the intestine to other areas of an animal’s body and proliferates, it can make the animal sick. Trueperella causes many problems in deer, including lesions, abscesses, and pneumonia, and it is one of the types of bacteria that is known to contribute to the disease lumpy jaw. In young fawns, it is a common cause of death. This 3-page fact sheet written by Kathryn D. Pothier, Katherine A. Sayler, and Samantha M. Wisely and published by the Department of Wildlife Ecology and Conservation explains how to spot and treat trueperella, or, better yet, prevent it in the first place.­http://edis.ifas.ufl.edu/uw427

ABSTRACT Arcanobacterium pyogenes, a common inhabitant of the mucosal surfaces of livestock, is also a pathogen associated with a variety of infections. In livestock, A. pyogenes is exposed to antimicrobial agents used for prophylaxis and therapy, notably tylosin, a macrolide used extensively for the prevention of liver abscessation in feedlot cattle in the United States. Many, but not all, tylosin-resistant A. pyogenes isolates carry erm(X), suggesting the presence of other determinants of tylosin resistance. Oligonucleotide primers designed for conserved regions of erm(B), erm(C), and erm(T) were used to amplify a 404-bp fragment from a tylosin-resistant A. pyogenes isolate, OX-7. DNA sequencing revealed that the PCR product was 100% identical to erm(B) genes, and the erm(B) gene region was cloned in Escherichia coli. The A. pyogenes Erm B determinant had the most DNA identity with an Erm B determinant carried by the Clostridium perfringens plasmid pIP402. However, the A. pyogenes determinant lacked direct repeat DR1 and contained a deletion in DR2. Flanking the A. pyogenes erm(B) gene were partial and entire genes similar to those found on the Enterococcus faecalis multiresistance plasmid pRE25. This novel architecture suggests that the erm(B) element may have arisen by recombination of two distinct genetic elements. Ten of 32 tylosin-resistant isolates carried erm(B), as determined by DNA hybridization, and all 10 isolates carried a similar element. Insertion of the element was site specific, as PCR and Southern blotting analysis revealed that the erm(B) element was inserted into orfY, a gene of unknown function. However, in three strains, this insertion resulted in a partial duplication of orfY.
