'''Three days after calving, a four-year-old Friesian cow became acutely ill, with brisket and submandibular oedema. She was stiff and grunted with respiration. Peritoneal fluid withdrawn from a site 5 cm cranial and 5 cm medial to the milk well had a TP of 48 g/l and an NCC of 37 ×109/l. A cytospun smear of the peritoneal fluid was prepared (Wright–Giemsa, ×50 oil).'''

<FlashCard questions="3">
|q1=What cells are present?
|a1=
*There is a lot of cell disruption and debris, making cell identification difficult. 
*However, the outline of neutrophils is visible in some cases and the disrupted cells are considered to be karyolytic neutrophils. 
*No microorganisms are seen.
|l1=
|q2=What is the fluid classification?
|a2=
An exudate.
|l2=
|q3=What is your diagnosis?
|a3=Acute peritonitis. <br><br>
Given the history and clinical signs, this is suggestive of foreign body reticuloperitonitis. <br><br>
Note: Reference values for NCCs and classification of effusions in large animals differ from those for small animal specimens.
