Diagnostic ultrasonography in cattle with diseases of the mammary gland.
Fifty-two cattle with diseases of the udder were evaluated by means of sonography between 2000 and 2004. The udders were examined with 3.5 and 5.0 MHz convex transducers and 7.5 and 13.0 MHz linear transducers. Bacteriological examinations were also performed on individual quarter samples. Ultrasonography gave additional information on the status of the udder and showed findings specific for some causal agents, e.g., Enterobacteriaceae and Arcanobacterium pyogenes as well as udder haematomas. All forms of mastitis required bacteriological confirmation for the final diagnosis.
