Workshop über Mykoplasmen
Published on January 7 2013
Liebe Freunde und Interessierte,
der 2. Workshop, an dem ich teilnehmen werde, befasst sich mit Mykoplasmen als Mastitiserreger. In westdeutschen, milchproduzierenden Betrieben werden Mykoplasmen als Mastitiserreger nicht häufig nachgewiesen. Dafür kommen im Wesentlichen 2 Ursachen in Frage: Mykoplasmen kommen als Mastitiserreger selten vor und/oder die Diagnostik bei Mykoplasmen ist insuffizient.
Zukünftig wird in Deutschland die Bedeutung von Mykoplasmen als Mastitiserreger zunehmen, weil die Betriebe rasant größer werden und dadurch das Mastitisgeschehen an Dynamik zunehmen wird. Die Erfahrungen und Kenntnisse mit Mykoplasmen als Mastitiserreger sind in den USA eindeutig umfangreicher als in Deutschland. Durch die Teilnahme an dem Workshop erwarte ich mir einen spürbaren Erkenntniszuwachs.
Herzliche Grüße
Reinhard T.

Course 3: Update on Mycoplasma Mastitis -- Transmission and Control
Date and time: Sunday, January 27, 6:30 pm - 9:30 pm
Class size limit: 40
Fee: $115
Level: Intermediate
Instructors: Larry Fox, Washington State University, Pullman, Washington; Allan Britten, Udder Health Systems, Boise, Idaho
Mycoplasma mastitis was first described in the 1960s in Connecticut, and within ten years had been reported to infect cattle across several countries around the world. Although it is most often described as a contagious pathogen, there are several reports indicating that milking time hygiene alone does not control, nor prevent, the mycoplasma mastitis disease complex. The most significant risk factor for the disease appears to be importation of cattle into a herd. Culling cows with mycoplasma mastitis is often advocated as a control element, although some reports suggest it is not universally successful. Recent studies have documented the spread of Mycoplasma species in herds with cows with mycoplasma mastitis to other cows and their replacements, almost invariably the infecting strain is involved in all transmissions. Carriage in the nose seems to be the most prevalent site of colonization. Findings indicate that strains are unique to a herd and some suggest that the udder is the primary reservoir, although other body sites (lungs, joints, and urogenital tracts) are clearly affected. These findings might suggest that udder to udder spread is not the sole means of transmission. An understanding of the transmission pathways of Mycoplasma sp. will aid in the control of the disease complex. The focus of the short course will be to discuss the new findings describing the epidemiology of mycoplasma mastitis and how it can be controlled. Participants will be provided with printed handouts of slides and supportive material.
Topics
• Mycoplasma mastitis transmission
• Mycoplasma mastitis control
• Mycoplasma prevalence within a herd contrasted between herds/countries
