Subject: Emergency Management Warning : Rabbit Hemorrhagic Disease
(ViralHemorrhagic Disease of Rabbits ) in Flushing, New York
> Rabbit Hemorrhagic Disease Confirmed in a Captive Exotic Animal Facility
> Flushing, New York
> Two out of six rabbits on exhibit in the domestic animal section at a
> captive exotic animal facility were found dead on Saturday, December 1 and
> Sunday, December 2, 2001, respectively. Two additional rabbits were in an
> off exhibit area for a total of eight rabbits in the collection. This is
> not considered a zoonotic disease. Animals were necropsied by zoo
> pathologists and lesions consistent with rabbit hemorrhagic disease (RHD)
> were found. Samples from the dead rabbits were sent to the Foreign Animal
> Disease Diagnostic Laboratory (FADDL) on Plum Island, NY. Test results
> were positive by hemagglutination on one rabbit and negative on the other
> on Friday, December 7, 2001. A third exhibited rabbit died on Sunday,
> December 9, 2001.
> The remaining rabbits were quarantined and isolated from other animals.
> The five remaining rabbits were euthanized on Monday, December 10, 2001,
> and additional samples will be sent to FADDL. Cleaning and disinfection
> the area will be done.
> From the epidemiological data gathered so far, the source of the virus is
> APHIS, Veterinary Services (VS), the State Department of Agriculture of
> York, and facility managers are working together to address this
> VS will assist the affected State in the depopulation and cleaning and
> disinfecting of the premises.
> VS will also investigate reports of suspect RHD as part of its foreign
> animal disease surveillance program and will continue to diagnose suspect
> cases at FADDL.
> DNA Sequencing Results from the Utah/Illinois RHD Outbreak in August 2001
> The sequence alignments were taken from the polymerase region of the RHDV
> genome. It showed distinct differences between the 3 isolates (Mexico,
> Korea, Utah) and the Iowa isolate. The sequence pair distance of the 3
> isolates had percent similarities of over 95% while the Iowa isolate
> differed more from the others. The biggest difference was between the
> and the Utah isolates at 14.5%.

- I don't remember seeing DNA sequencing in other posts about VHD.
Does this mean there have been three different strains of VHD in the
I honestly don't know, Val. Seemed rather unclear; I left a message for Dr. Boghossian today and will be calling again first thing in the morning to find out just what that meant :).
I will post all information I have ASAP, as before, in regards to this latest outbreak.
If anyone has further info, please let me know.
