stained blood smear is an essential component of a CBC, as automated analyzers do not detect hemoparasites.
Photomicrograph of the feathered edge of a blood smear showing pleomorphic RBC inclusions in a sample from a 5-month-old sexually
smear allows for confirmation of the automated cell counts and screening for potentially clinically relevant abnormalities, such as band neutrophils, toxic changes, hemoparasites, or nucleated RBCs. Preparation and examination of the blood smear does
-needle aspirate obtained from a nodule in the left caudal lung lobe revealed a predominant population of moderately degenerate neutrophils, fewer macrophages, and erythrocytes containing a heavy burden of extracellular hemoparasites consistent with Mycoplasma
The neurologic findings were most likely a result of a neuromuscular lesion.
Differential diagnoses considered for the dog included metabolic (electrolyte disturbances, endocrinopathies), infectious (hemoparasites
, salmonellosis, colibacillosis, clostridiosis, mycoplasmosis, and infection with Plasmodium spp or other hemoparasites and viruses), bacterial septicemia, aflatoxicosis or other toxicoses (eg, lead, zinc, or crude oil), neoplasia, drug reaction, vaccine
hemofelis, Mycoplasma hemominutum, Mycoplasma turicensis, Rickettsia rickettsia , and Rickettsia felis . Although bobcats are natural reservoir hosts for Cytauxzoon felis , 1,2 no evidence of hemoparasites was observed on clinicopathologic assessment of
]) to assess whether the morphology of the cells (eg, agglutination, schistocytosis, spherocytosis, leptocytosis, hemoparasites, and leukemic cells) was consistent with the clinical diagnosis in the medical record. This led to the exclusion of samples
In the US, feline cytauxzoonosis is a rapidly progressive and often fatal condition of domestic cats caused by Cytauxzoon felis (CF). CF is a tick-transmitted protozoal hemoparasite endemic to the southeastern and south
Romanowsky-type stain c was performed by the attending veterinarian at the clinic, and intracellular inclusions consistent with hemoparasites were detected within RBCs.
The attending veterinarian immediately sent the blood smear to the University of
the unique features of avian blood cells, with a review of the hematologic differences among the various avian orders. The final chapters cover physiologic and pathological effects on avian blood cells as well as a description of avian hemoparasites
