#313  Common Bacterial Diseases of Koi

          This course will address bacteria in general and the common pathogens of Koi in particular.  The course CD includes animations and movies which are helpful in understanding the material presented.  Koi Keepers enrolling in this course will learn to understand bacteria, what the common bacterial diseases of Koi are, how to use gram stain procedures, options for bacterial treatment, and how to prevent bacterial disease in Koi.

          This course requires additional material which will need to be purchased in advance.  You will need to own, or have access to a microscope.  You will want to get a bacterial stain kit (e.g. Gram's stain) if you don't have one.  Suggested sites to obtain supplies are:  Connecticut Valley Biological product #ST 525A or Auspex Scientific # APGS100.  At these sites, you will also find the nutrient agar plates and inoculating loops which you will need.

          It is recommended that those enrolling in this course are not only competent in the use of a microscope but also have some knowledge of bacterial problems in Koi.  While this is considered an advanced-level course, even those with moderate Koi and scope experience will learn a tremendous amount, and have fun doing it!
