Long-term, intermittent, low-level elephant endotheliotropic herpesvirus 1A viremia in a captive Asian elephant calf.

A 2-y-old male Asian elephant ( Elephas maximus), with an elevated platelet count (1,100 × 10/L [1,100 × 10/mm]), tested positive for elephant endotheliotropic herpesvirus 1A (EEHV-1A) on conventional PCR (cPCR) of EDTA whole blood. No clinical signs were ever reported and no treatment was administered, but low-level viremia persisted for 2.5 y based on results of cPCR and/or real-time PCR (rtPCR).

OUTBREAK OF MYCOBACTERIUM TUBERCULOSIS IN A HERD OF CAPTIVE ASIAN ELEPHANTS ( ELEPHAS MAXIMUS): ANTEMORTEM DIAGNOSIS, TREATMENT, AND LESSONS LEARNED.

Tuberculosis (TB) was diagnosed in four Asian elephants ( Elephas maximus) in a zoo in the United States. The first case was detected by isolation of Mycobacterium tuberculosis during routine trunk wash (TW) culture testing of a herd of eight elephants. Retrospective antibody analyses revealed seroconversion 1 yr before diagnosis.

Diagnosis of Tuberculosis in Three Zoo Elephants and a Human Contact - Oregon, 2013.

In 2013, public health officials in Multnomah County, Oregon, started an investigation of a tuberculosis (TB) outbreak among elephants and humans at a local zoo. The investigation ultimately identified three bull elephants with active TB and 118 human contacts of the elephants. Ninety-six (81%) contacts were evaluated, and seven close contacts were found to have latent TB infection.

Conjunctival-corneal intraepithelial neoplasm in an Asian elephant (Elephas maximus).

An adult female Asian elephant (Elephas maximus) presented with an enlarging nasal limbal mass of the left eye. The mass was excised and the surgical bed treated with liquid nitrogen cryotherapy. Histopathologic examination of the excised tissue showed the mass to be a superficial dysplastic ocular lesion, or conjunctival intraepithelial neoplasm.

A Pasteurella-like bacterium associated with pneumonia in captive megachiropterans.

A novel Pasteurella-like organism was recovered postmortem from lung tissue of two captive Wahlberg's epauleted fruit bats (Epomophorus wahlbergi), with severe, unilateral pneumonia. The bats had been recently shipped and died shortly after release from a 30-day quarantine. One presented with clinical signs of anorexia and lethargy before death; the other died without prior clinical symptoms.
