AI Article Synopsis
- Associated abomasitis is identified as a possible cause of sudden death in lambs, but its characteristics are not well understood.
- A study described severe fibrinonecrotizing abomasitis in three lambs, highlighting pathological features like thickened submucosa, necrotic areas, and the presence of gram-negative coccobacilli.
- Clostridial co-infection was suggested, with additional complications seen in two lambs, indicating the need to include this condition in differential diagnoses for necrotizing abomasitis in lambs.
Article Abstract
-associated abomasitis has been clinically described as a cause of sudden death in lambs, but it is poorly characterized. We describe the pathological features of a severe fibrinonecrotizing abomasitis in 3 lambs that died suddenly. All 3 abomasums had a thickened submucosa due to edema and necrotic areas delimited by bands of degenerate neutrophils with slender nuclei (oat cells) and angiocentric distributions. The overlying mucosa was congested. Myriads of gram-negative coccobacilli were observed within the oat cell bands. was isolated from the abomasum in all 3 animals and was serotyped as A2 in one of them. Pericarditis and pleuritis were observed in 2 of the lambs. spp. were isolated in 1 lamb and detected by immunohistochemistry in the 3 animals, suggesting clostridial co-infection. should be considered among the differential diagnoses of necrotizing abomasitis in lambs.
