Calodium hepaticum (syn. Capillaria hepatica), a nematode parasite commonly found in the liver of wild rodents, infects a wide variety of mammals, including humans. A retrospective study of black-tailed prairie dogs (Cynomys ludovicianus) at the Baltimore Zoo showed that 5 of 21 (24%) of the prairie dogs submitted for postmortem examination between 1981 and(More)
A high prevalence of urinary bladder transitional-cell carcinoma (TCC) has been noted in captive fishing cats (Prionailurus viverrinus). Of the 91 adult deaths between 1995 and 2004, 12 (13%) were attributed to TCC. To help elucidate mechanisms of carcinogenesis, archival sections of urinary bladder from 14 fishing cats were examined histologically and(More)
This report documents a case of spontaneous, fatal, and likely recrudescent human herpesvirus type 1 (HHV-1) infection in a captive white-handed gibbon (Hylobates lar) confirmed by polymerase chain reaction (PCR). An approximately 44-year-old, captive, female, white-handed gibbon with a history of recurrent conjunctivitis and occasional seizures became(More)
PURPOSE Variation in the effects of selective estrogen receptor modulators (SERMs) on the estrous cycle and reproductive organs during aging could play an important role in the observed heterogeneity of tamoxifen chemoprevention efficacy against breast cancer. METHODS Of the 1,022 female Sprague Dawley rats enrolled in a long-term tamoxifen(More)
Infectious disease is an important factor in Asian elephant health and long-term species survival. In studying disease pathogenesis, it is important to consider not only the pathogen, but also the effectiveness of the host immune response. Currently, there is a paucity of information available on elephant immune function. Measurement of cytokine levels(More)
Mycobacterium spp. infection is an important health concern for Asian elephant (Elephas maximus) populations worldwide. The disease is of particular concern considering its potential to affect not only the individual animal but also herd and public health. Although elephant tuberculosis susceptibility is poorly understood, immune function alterations are(More)
Although Mycobacterium tuberculosis infection is an important health concern for Asian elephants (Elephas maximus), no studies have evaluated the associated local immune responses or histologic lesions. In primates including humans, latent tuberculosis is distinguished by well-organized granulomas with TH1 cytokine expression, whereas active disease is(More)
Tuberculosis is an important health concern for Asian elephant (Elephas maximus) populations worldwide, however, mechanisms underlying susceptibility to Mycobacterium tuberculosis are unknown. Proliferative responses assessed via brominated uridine incorporation and cytokine expression measured by real-time RT-PCR were evaluated in peripheral blood(More)
A novel herpesvirus was detected in a captive mob of eastern grey kangaroos (Macropus giganteus) during diagnostic workup for individuals with ulcerative cloacitis. Virus was initially detected in tissues using a consensus herpesvirus PCR. No viral inclusions or particles had been evident in routine histologic or transmission electron microscopic sections(More)
Nanoparticle-encapsulated thiazole antibiotic, thiostrepton, has been shown to be an effective agent for inhibiting tumor growth in solid tumor models through the inhibition of proteasomal activity by the induction of apoptosis in cancer cells. Here, we show the efficacy of thiostrepton-micelles in inhibiting tumor growth in a DEN/PB-induced liver cancer(More)
