ROB FAIRLEYIf you require brain histology performed, you should ideally send the whole brain, fixed in formalin, to the laboratory. If you need to take a fresh sample, you can remove a small portion no problem.We receive submissions every now and then that consist of cerebral cortex only. If you are specifically checking for polio […]
BERNIE VAATSTRAThis month we present two cases caused by the same aetiological agent.Case 1:Seven first-calving Friesian heifers from a Waikato dairy herd developed fever and respiratory distress and three died after returning from grazing and presumably being exposed to BHV-1 circulating in the home herd. Necropsy findings included severe necrotising tracheitis (Figure 1) and pneumonia. […]
We featured an article in June 2019 regarding factors that can interfere with ACTH testing for diagnosis of Pars Pituitary Intermedia Dysfunction (PPID) in horses. Since both non-PPID and PPID horses display higher ACTH concentrations in autumn (March, April, May) compared with other times of the year, now is a timely reminder of these interfering factors.>> […]

(Figures 1-3). The cat’s skin was otherwise unremarkable, and the only other clinical findings were lean body condition and […]
GEOFF ORBELLDo you often have small or fragile biopsies or samples for histology that would benefit from some TLC?We stock special cassettes with an extremely fine mesh that prevents tissue loss during processing and protects small or fragile biopsies. These are great for endoscopic biopsies, nasal biopsies, crusts from skin disease, or small biopsies where […]
