Complete Genome Sequences of Microbacterium paraoxydans Phages Cassita and Fransoyer.

Phages Cassita and Fransoyer were isolated from soil in northwestern Wisconsin using Microbacterium paraoxydans as the host. The genomes of Cassita and Fransoyer are 61,868 bp and 62,277 bp, respectively, with direct terminal repeats. Both phages exhibit siphoviral morphology and are predicted to have lytic life cycles.

Quantitative and Qualitative Behavioral Measurements to Assess Pain in Axolotls ().

Effective pain relief in animals relies on the ability to discern pain and assess its severity. However, few objective measures exist to assess the presence and severity of pain in axolotls, and few resources are available regarding drugs and appropriate doses to provide pain relief in this species. This study evaluated behavioral tools for cageside pain assessment and validated a reproducible and reliable quantitative method to evaluate analgesic efficacy in axolotls.

Metastatic Osteolytic Angioleiomyosarcoma Induced by a Foreign Body in a Kangaroo (Macropus giganteus).

An adult female Eastern Grey kangaroo (Macropus giganteus) was examined for lameness due to a mass located at the right tibiotarsal joint. Radiographs revealed a metal arrowhead-shaped foreign body within the mass alongside a pathologic fracture. Grossly, at necropsy, there was a multilobulated and haemorrhagic mass with intralesional metal fragments, associated osteolysis of the tibiotarsus and pulmonary metastatic nodules.

Multicentric plasmacytoma in a harbor porpoise Phocoena phocoena off the coast of Whidbey Island, Washington State, USA.

Necropsy of a female adult pregnant harbor porpoise Phocoena phocoena revealed a multicentric plasmacytoma. The plasmacytoma infiltrated the cranial lung lobes, mediastinal lymph nodes and the spleen. Diagnosis was based on gross, histopathologic and immunohistochemical studies.

Biodistribution and Clearance of Stable Superparamagnetic Maghemite Iron Oxide Nanoparticles in Mice Following Intraperitoneal Administration.

Nanomedicine is an emerging field with great potential in disease theranostics. We generated sterically stabilized superparamagnetic iron oxide nanoparticles (s-SPIONs) with average core diameters of 10 and 25 nm and determined the in vivo biodistribution and clearance profiles. Healthy nude mice underwent an intraperitoneal injection of these s-SPIONs at a dose of 90 mg Fe/kg body weight.
