ROB FAIRLEYDid you know that encephalitic listeriosis and enteric listeriosis are two quite separate diseases? It would be uncommon for these two conditions to occur at the same time.Enteric listeriosis mainly occurs when sheep are fed poor-quality baleage or silage, and clinical signs develop within a few days of consuming the poor-quality feed as large […]

(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 […]

MICHAEL HARDCASTLEIt is very common for clinicians to call the laboratory asking how long they should wait before sampling a skin problem that has already been treated empirically with glucocorticoids.If one consults standard texts on veterinary dermatology, these generally contain recommendations to wait because “anti-inflammatory agents can dramatically affect the histologic appearance of many dermatoses”.1,2 […]
ROB FAIRLEYHere are some tips from our pathologists that may be useful during sample collection or out in the field.1. For PCR, dry swabs are preferred over transport media swabs. We have had success with transport media swabs but the material you collect on the swab is diluted by the media and there is a risk […]
KATHRYN JENKINSDid you know you can submit up to six slides per site, for each cytology case?Cytology tip:Increasing the number of sites sampled from each lesion, increases the diagnostic power for a more accurate interpretation. In many cases, increasing the sample number taken, improves the chances of a diagnostic sample (often we find that the […]
