For those of you that might be interested, I am posting a study done in the Czech Republic in 2007 about testing Koi for KHV.  They too conclude that the best option is prevention!  Scroll down to read the article...

Copper is ubiquitous in our environment - from pesticides to pipe.  Some copper gets into our ponds and this study shows how even small amounts affect Koi in many damaging ways.  This study goes into great detail to show the effects on the brain, blood, liver, gills, and kidneys based on very low exposure to copper.

This study evaluates the toxic residual pharmaceuticals in the water as they affect algae, the environment and fish.  The results indicate that there are numerous other external factors that complicate the testing.  An interesting study, not directly related to our Koi, but certainly affecting our water sources.  The list of chemicals they tested for is staggering!

This research describes how monoclonal antibodies were successfully developed for use in diagnosing disease of carp (including Koi).  The results are then used to develop specific antibodies to detect Spring Viremia of Carp (SVC).  The hope is to develop a vaccination against SVC based on these findings.

This study examines the effects of nitrite poisoning, and how to prevent it.  As a further benefit, the study examines the carp's ability to recover.  This is something every Koi keeper needs to know, as it will be useful each time a filter is 'started.'

It was originally thought that analyzing white blood cells in carp was an indicator of the age of the fish.  This study refutes that finding.

This study investigates whether age or weight affects a Koi's resistance to bacterial disease. 

When a swab is sent to a lab for a bacterial identification (culture and sensitivity test), an API 20E test is commonly used.  But is it missing other pathogenic bacteria?

Heavy metals are toxic to fish, including our Koi.  Understanding the effects of heavy metals, and which metals are toxic is useful to Koi keepers.

In these 2 studies, other species of fish were tested to see if they could be carriers of KHV.
