Reduced capability of refrigerated white rhinoceros whole blood to produce interferon-gamma upon mitogen stimulation.

Ante-mortem surveillance for Mycobacterium bovis (M. bovis) infection in the Kruger National Park (KNP) rhinoceros population currently relies on results from the QuantiFERON-TB Gold (In-Tube) Plus (QFT)-interferon gamma (IFN-γ) release assay (IGRA). However, same-day processing of rhinoceros blood samples for this test is a logistical challenge.

Epidemiology of infection in free-ranging rhinoceros in Kruger National Park, South Africa.

Mycobacterium bovis infection, which is a prominent cause of bovine tuberculosis, has been confirmed by mycobacterial culture in African rhinoceros species in Kruger National Park (KNP), South Africa. In this population-based study of the epidemiology of M. bovis in 437 African rhinoceros (Diceros bicornis, Ceratotherium simum), we report an estimated prevalence of 15.

Mycobacterium bovis Infection in Free-Ranging African Elephants.

Mycobacterium bovis infection in wildlife species occurs worldwide. However, few cases of M. bovis infection in captive elephants have been reported.

EVALUATION OF A PARTIALLY REVERSIBLE IMMOBILIZATION PROTOCOL USING MEDETOMIDINE, BUTORPHANOL, ZOLAZEPAM-TILETAMINE, AND KETAMINE IN FREE-RANGING WARTHOGS () IN KRUGER NATIONAL PARK, SOUTH AFRICA.

Twenty-one free-ranging warthogs () in the Kruger National Park, South Africa, were immobilized with a combination of medetomidine (0.07 ± 0.01 mg/kg), butorphanol (0.

Evaluation of Physiological Parameters and Effectiveness of an Immobilization Protocol Using Etorphine, Azaperone, and Butorphanol in Free-Ranging Warthogs ().

Twenty free-ranging warthogs () in the Kruger National Park, South Africa, were immobilized with a combination of etorphine (0.039 ± 0.005 mg/kg) and azaperone (0.

AN INTERFERON GAMMA RELEASE ASSAY FOR THE DETECTION OF IMMUNE SENSITIZATION TO IN AFRICAN WILD DOGS ().

In South Africa, the largest proportion of the African wild dog () population resides in regions where buffaloes have a high prevalence of , the causative agent of bovine tuberculosis (bTB). Recent reports of deaths of wild dogs associated with bTB have raised concerns regarding the threat this disease might pose for this species. In order to understand the potential impact of the disease in wild dogs, diagnostic tools are required to identify infected individuals.

Conservation of White Rhinoceroses Threatened by Bovine Tuberculosis, South Africa, 2016-2017.

During 2016-2017, when Kruger National Park, South Africa, was under quarantine to limit bovine tuberculosis spread, we examined 35 white and 5 black rhinoceroses for infection. We found 6 infected white rhinoceroses during times of nutritional stress. Further research on Mycobacterium bovis pathogenesis in white rhinoceroses is needed.
