Assessment of the immunogenicity of rabies vaccine preserved by vaporization and delivered to the duodenal mucosa of gray foxes (Urocyon cinereoargenteus)
Smith TG , Wu X , Ellison JA , Wadhwa A , Franka R , Langham GL , Skinner BL , Hanlon CA , Bronshtein VL . Am J Vet Res 2017 78 (6) 752-756 OBJECTIVE To assess the immunogenicity of thermostable live-attenuated rabies virus (RABV) preserved by vaporization (PBV) and delivered to the duodenal mucosa of a wildlife species targeted for an oral vaccination program. ANIMALS 8 gray foxes (Urocyon cinereoargenteus). PROCEDURES Endoscopy was used to place RABV PBV (n = 3 foxes), alginate-encapsulated RABV PBV (3 foxes), or nonpreserved RABV (2 foxes) vaccine into the duodenum of foxes. Blood samples were collected weekly to monitor the immune response. Saliva samples were collected weekly and tested for virus shedding by use of a conventional reverse-transcriptase PCR assay. Foxes were euthanized 28 days after vaccine administration, and relevant tissues were collected and tested for presence of RABV. RESULTS 2 of 3 foxes that received RABV PBV and 1 of 2 foxes that received nonpreserved RABV seroconverted by day 28. None of the 3 foxes receiving alginate-encapsulated RABV PBV seroconverted. No RABV RNA was detected in saliva at any of the time points, and RABV antigen or RNA was not detected in any of the tissues obtained on day 28. None of the foxes displayed any clinical signs of rabies. CONCLUSIONS AND CLINICAL RELEVANCE Results for this study indicated that a live-attenuated RABV vaccine delivered to the duodenal mucosa can induce an immune response in gray foxes. A safe, potent, thermostable RABV vaccine that could be delivered orally to wildlife or domestic animals would enhance current rabies control and prevention efforts. |
Juxtaarticular myxoma in a pigtail macaque (Macaca nemestrina)
Skinner BL , Johnson CH , Lacy SH . Comp Med 2016 66 (5) 420-423 A 10-y-old pigtail macaque presented with a subcutaneous, soft-tissue mass overlying the right stifle joint. Here we describe the clinical case and histopathologic and immunohistochemical analysis of this lesion. This case represents the first published report of juxtaarticular myxoma in a pigtail macaque. |
Natural infection of Burkholderia pseudomallei in an imported pigtail macaque (Macaca nemestrina) and management of the exposed colony
Johnson CH , Skinner BL , Dietz SM , Blaney D , Engel RM , Lathrop GW , Hoffmaster AR , Gee JE , Elrod MG , Powell N , Walke H . Comp Med 2013 63 (6) 528-35 Identification of the select agent Burkholderia pseudomallei in macaques imported into the United States is rare. A purpose-bred, 4.5-y-old pigtail macaque (Macaca nemestrina) imported from Southeast Asia was received from a commercial vendor at our facility in March 2012. After the initial acclimation period of 5 to 7 d, physical examination of the macaque revealed a subcutaneous abscess that surrounded the right stifle joint. The wound was treated and resolved over 3 mo. In August 2012, 2 mo after the stifle joint wound resolved, the macaque exhibited neurologic clinical signs. Postmortem microbiologic analysis revealed that the macaque was infected with B. pseudomallei. This case report describes the clinical evaluation of a B. pseudomallei-infected macaque, management and care of the potentially exposed colony of animals, and protocols established for the animal care staff that worked with the infected macaque and potentially exposed colony. This article also provides relevant information on addressing matters related to regulatory issues and risk management of potentially exposed animals and animal care staff. |
