Bovine CBC reveals concurrent BLV and Anaplasmosis
Bovine CBC reveals concurrent BLV and Anaplasmosis By Julie Piccione, DVM, MS, DACVP An adult angus bull was presented to a veterinarian for lethargy and weakness. The bull died shortly after blood collection. Blood and tissue samples were submitted to the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL). The complete blood count revealed a marked leukocytosis characterized by a lymphocytosis at 43,000 lymphocytes/µL (reference interval...

Coombs Direct & CBC Profile – Small Animal
Detection of IgG, IgM or C3 on erythrocytes via direct antiglobulin test (direct Coombs test); measurement of WBC, RBC, HGB, HCT, MCV, MCH, MCHC, RDW, reticulocytes, PLT, PCT, MPV; and microscopic blood smear review for WBC differential, cellular morphology, and hemoparasites. A positive Coombs can support the diagnosis of immune-mediated hemolytic anemia (IMHA) when compatible clinical and CBC findings are present.

Juvenile lymphoma in an Angus calf
...ry (TVMDL) for a complete blood count (CBC) and cytologic examination. The CBC showed a marked lymphocytosis, marked anemia, and thrombocytopenia (see Table 1). A pathologist reviewed the blood smear and lymph node aspirates. The lymph node aspirates showed a monomorphic population of intermediate to large lymphocytes (see Figure 1a). Similar cells were observed in the blood smear (see Figure 1b). A diagnosis of juvenile lymphoma was made. Result...

Ehrlichia canis discovered in dog
...for CBC and chemistry panels. The chemistry panel was unremarkable. On the CBC, there was a marked thrombocytopenia (20,000 K/µL), mild lymphocytosis, and minimal decrease in HCT. Blood smear examination confirmed the thrombocytopenia. On the feathered edge of the blood smear, rare monocytes containing morula (Figure 1) were observed. Based on this finding, TVMDL’s Tick-Borne Pathogen Multiplex (rtPCR) test was performed and confirmed the presence...

The Advia 120 hematology analyzer was able to report a WBC count of 160.0 K/µL (reference interval 6.0 – 17.5 K/µL). While performing a microscopic exam of the peripheral blood smear, rare gamonts were noted within WBCs (Figure 1). Figure 1. One of several rare gamonts noted in WBC. These gamonts were co...

Tick-borne disease in a dog with no known history of ticks

The CBC findings were compatible with Tick-Borne Relapsing Fever, which was later confirmed with the TickPath Layerplex qPCR test at TVMDL. In the state of Texas, Tick-Borne Relapsing Fever (TBRF) is caused by Borrelia turicatae, which is spread by Ornithodoros turicata, a soft-bodied tick. These ticks are nocturnal, feeding on their hosts briefly at night. Therefore, it is not...

How to properly prepare a blood smear
...C). At the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL), all CBCs include manual blood smear examination by a highly skilled clinical pathology technician, a clinical pathologist, or both. Ideally, blood smear evaluation should be performed on a properly prepared blood smear to improve the assessment of all cell lines. Freshly prepared blood smears should be submitted with all EDTA blood for CBC tests. Blood smear evaluation can help...

IMHA in dogs secondary to Babesia gibsoni diagnosed at TVMDL
...ple samples for Coombs testing came from young to adult Pit Bull dogs with CBC data suggestive of IMHA. Evaluation of blood smears at TVMDL revealed numerous organisms consistent with Babesia gibsoni (see image), which were later confirmed by PCR. Babesia gibsoni is most commonly observed in pit bull terriers and greyhounds and infections are reported in several states throughout the US. IMHA is suspected when compatible CBC findings are observed,...

Onion (Allium sp.) and wilted maple leaf (Acer sp.) ingestion were suggested as possible differentials. Several days later, the vet called back to let us know that a tree in the horse pasture had been badly damaged by storms and branches had been down for several days before the horse began...

A minimum data base (CBC, Chemistry, and urinalysis) was performed in-house and revealed only a markedly increased ALKP activity, low lymphocyte count, and a low urine specific gravity (specific values were not provided). The veterinarian suspected Cushing’s disease and the next day the dog returned for a low dose dexamethasone suppression test. A “pre” blood sample was collected and then 0.01...
