…a patent infection is the Baermann technique on fresh feces obtained on rectal exam (Question 3).1Β It is not recommended to obtain feces from the ground, as environmental contamination can confound results. The BaermannΒ test identifies first-stage larvae, which are approximately 300 β 360 ΞΌm long.2 Alternatively, identification of the white long (up to 8.0 cm in length) mature adult lungworms in the bronchi, mainly in the caudal lobes, on necrop…
…ncentrated urine (the concentration of which is determined by the degree of tonicity of the medulla). This is accomplished as follows: 1. Normally the glomerular filtrate has a similar osmolality to plasma (300 mOsmol/kg). In the descending limb of the loop of Henle, the NaCl cannot be absorbed, but water is passively resorbed (#1), creating a hypertonic urine (>1200 mOsmol/kg) as it enters the ascending limb. 2. When this NaCl-rich fluid enters…

This dog had a marked leukocytosis (300,000/uL) consisting of large blasts with a concurrent pancytopenia (non-regenerative anemia, neutropenia, severe thrombocytopenia. Some of the cells had coarse red-purple granules. A few eccentrocytes are evident, indicating a degree of oxidant injury (not uncommon in dogs with cancer) (Wrightβs stain, 500x magnification). This indicates an acute leukemia, which could be myeloid or lymphoid. A bone m…

…. The next day, a persistent cough was noted. Lung sounds were mildly harsh cranioventrally with little nasal discharge. Nostrils were bilaterally patent, with normal bronchovesicular sounds over the trachea. Thoracic radiographs and ultrasound confirmed mild bilateral cranioventral disease, with an interstitial-to-alveolar pulmonary pattern. Results from the hemogram are shown below. A fibrinogen byΒ heat precipitation was 300 mg/dL (0-200…
