An ovine model for investigation of the microenvironment of the male mammary gland.

The specific biology of the male breast remains relatively unexplored in spite of the increasing global prevalence of male breast cancer. Delineation of the microenvironment of the male breast is restricted by the low availability of human samples and a lack of characterisation of appropriate animal models. Unlike the mouse, the male ovine gland persists postnatally.

In the Murine and Bovine Maternal Mammary Gland Signal Transducer and Activator of Transcription 3 is Activated in Clusters of Epithelial Cells around the Day of Birth.

Signal transducers and activators of transcription (STAT) proteins regulate mammary development. Here we investigate the expression of phosphorylated STAT3 (pSTAT3) in the mouse and cow around the day of birth. We present localised colocation analysis, applicable to other mammary studies requiring identification of spatially congregated events.

Arcanobacterium haemolyticum in a badger (Meles meles).

A 7.5-kg female European badger (Meles meles) was submitted under the United Kingdom Government's Wildlife Incident Investigation Scheme to the Thirsk Regional Laboratory of the Animal Health and Veterinary Laboratories Agency. Postmortem examination revealed a large, poorly encapsulated retropharyngeal abscess full of necrotic debris and pus.

Reassortant Pandemic (H1N1) 2009 virus in pigs, United Kingdom.

Surveillance for influenza virus in pigs in the United Kingdom during spring 2010 detected a novel reassortant influenza virus. This virus had genes encoding internal proteins from pandemic (H1N1) 2009 virus and hemagglutinin and neuraminidase genes from swine influenza virus (H1N2). Our results demonstrate processes contributing to influenza virus heterogeneity.
