QUESTION

Leucocytosis with shift to left is observed in bitches affected with?

OPTIONS

(A) Endometritis
(B) Vaginitis
(C) Pyometra
(D) Cervicitis

ANSWER

(C) Pyometra

EXPLANATION

Canine pyometra commonly causes a marked inflammatory leukogram, including neutrophilic leukocytosis and a left shift due to release of immature neutrophils. Localized vaginitis or cervicitis usually produces less pronounced systemic effects. Endometritis can also cause inflammation, but pyometra is the strongest association with a severe systemic leukogram. Advanced overwhelming infection may instead produce leukopenia, so leukocytosis is not obligatory.
