A, Exudate. Septic peritonitis. Dog.

Numerous degenerate neutrophils are noted with a large number of pleomorphic bacteria seen, both in the background and within neutrophils. This concentrated smear was made from a dog with a ruptured pancreatic abscess. (Modified Wright; HP oil.) B, Septic exudate. Pleural. Cat. Degenerate neutrophils are bloated, with foamy or vacuolated cytoplasm and also swollen lytic nuclei. Note presence of small gram-positive, pleomorphic bacterial rods. Aerobic and anaerobic cultures are recommended in cases of pyothorax. This sample contains many nucleated cells (greater than 100,000 cells/μL) and greater than 3.0 g/dL protein. (Gram; HP oil.)
