Four PCR-positive field shrimp do not create a tank diagnosis
The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.
What changed
The health guide now includes the first direct microsporidian field report in Neocaridina davidi and separates its one-site molecular detections from aquarium prevalence, visible diagnosis, disease severity, transmission and treatment.
Why it changed
The study screened 75 ethanol-preserved adults from one German stream and one date using PCR on muscle tissue. Four were positive, but only three randomly selected hosts received CO1 confirmation, only two of three E. hepatopenaei-like sequences entered the phylogeny, and the paper reported no histology, lesions, clinical signs, survival, transmission test or treatment comparison.

Affected practical guides
A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
