Bovine viral diarrhea virus (BVDV) is an emerging infectious pathogen of concern to the alpaca industry. A 4-month-old, intact, male alpaca cria was diagnosed as persistently infected with BVDV on the basis of repeated positive antemortem polymerase chain reaction (PCR) and virus isolation (VI) assays and negative serologic titers to BVDV.(More)
A 10-year-old Akita mix became acutely paraplegic. Upon magnetic resonance imaging, multiple, slightly T2-hyperintense, T1-isointense extradural masses, relative to spinal cord were found in the vertebral canal. The retroperitoneal masses had mixed T2-signal intensity. The contrast enhancement pattern for the spinal masses was both homogenous and(More)
We describe the development and analytical validation of a 7-plex polymerase chain reaction assay coupled to a bead-based liquid suspension array for detection of multiple ruminant Mycoplasma spp. The assay employs a combination of newly designed and previously validated primer-probe sets that target genetic loci specific for Mycoplasma bovis, Mycoplasma(More)
The use of automated watering systems for providing drinking water to rodents has become commonplace in the research setting. Little is known regarding bacterial biofilm growth within the water piping attached to the racks (manifolds). The purposes of this project were to determine whether the mouse oral flora contributed to the aerobic bacterial component(More)
Three dogs were examined for clinical signs ultimately attributed to systemic fungal infections. One dog was evaluated for chronic, ulcerated dermal lesions and lymphadenomegaly; one dog was examined for acute onset of unilateral blepharospasm; and one dog had diarrhea and hematochezia. Two of the dogs were diagnosed with blastomycosis (one with(More)
A 2-yr-old male intact alpaca (Vicugna pacos) was admitted for a 4-day history of anorexia and colic. Five months prior, the alpaca had undergone surgical removal of a duodenal trichophytobezoar and had recovered uneventfully. The alpaca died under anesthesia, and diaphragmatic herniation of the third gastric compartment (C3) was diagnosed at necropsy. A(More)
