Signalment: Two calves, 3 days old and 7 days old
History: Farm unsure if calves got colostrum, their navels were not dipped
Clin Signs: No suckle reflex, depressed, dull, recumbent
Calves died while undergoing treatment at SVM, brought to pathology lab.
Pathology: Limbs revealed the presence of a suppurative arthritis, erosion of cartilages within many limb joints. This was evidenced by the thinning of the cartilage on the articular surfaces, the presence of blood and yellowish material (possibly pus) in the joint cavity.
Cytology was done on some of the joint fluid aspirated, the slide revealed a massive number of neutrophils present.
The brains of the calves were removed also. One of them showed pus within the sulci of the brain especially on the ventral surface. This indicated a suppurative meningitis.
For now, there hasnt been any identification on the organism. As more is revealed, anyone can update this post.

'Pussy joints'
Avian case from Group D.
Chicken farmer complained of lame birds and said they had pus in their joints. On Friday 22nd Aug approx ten 25-day old chicks were sent for post-mortem examination. The PM was done on Tuesday 26th.
Findings in all birds: soft bones, enlarged costo-chondral junctions (rachitic rosary)
No other significant lesions were seen, and no pus was seen in any joint of any bird.
Conclusion: the flock is suffering from rickets due to Vitamin D3 deficiency, which can lead to severe lameness in chickens. The claim of pus in the joints was likely an incorrect assumption on the part of the farmer. Vitamin D supplementation will be prescribed.
