S/O: Client has been dealing with a few patients that continue to lose weight and are not eating.  Client first noted affected individuals were passing long mucoid fecal casts that would remain attached at the patient’s vent and under microscopy contained numerous protozoal parasites.  This was first observed 4-5 months ago.  Based on images the client captured under microscope, the tank was treated with several courses of medications including praziquantel, levamisole, metronidazole, and a fluroquinolone.  Mild and brief improvement was noted. Repeat fecals revealed some similar and some new parasitic species, but no real improvement in clinical signs. 
The poorest doing of the affected fish was selected for euthanasia and histopathology.
Assessment/Procedures: Patient extremely emaciated.  Does show mild interest in food, but regurgitates immediately.  Patient was isolated from tank mates in 1 gallon bucket and 500mg/L buffered MS-222 added.  Patient was non-responsive and floating upside down within 3 minutes.  Patient was retrieved and placed in 10% formalin.
Pathology Results: See attached report for full interpretation.  Major finding: Severe necrotizing subacute to chronic bacterial enteritis.           
Discussion: So seems we were fighting the wrong pathogen all along.  There is some mention of mild parasitic branchitis (inflammation of the gills), but this is most likely secondary to his debilitated state.  There was also some inflammation noted of gallbladder and hepatopancreas, but this is more than likely the result of parasitic migration from the gi tract.  We were not able to discern the specific species of bacteria affecting this individual however it does appear to be a gram negative species that we can focus our future treatments towards.  Acid fast stains were negative so we do know we are not dealing with Mycobacteria, which is always a good thing. Likely those individuals that may have already developed granulomas may be too far gone.  Let’s plan a visit soon to discuss the current condition of all individuals and decide on a course of antibiotic treatment.
