Survey of the Clinical, Cytological, and Histopathological Features Associated with Neoplasms in Captive Avian Species in Melbourne, Australia.

Over a 3.5-year period, tissue samples from 141 companion and aviary birds with clinically suspected, naturally occurring solid neoplasms were collected via surgical biopsy (n = 53) or at necropsy examination (n = 88) from a population of birds presenting to an avian veterinary clinic in Melbourne, Australia. Neoplastic processes were identified in 73.

Immunoreactivity of canine, feline, and equine D-dimer with antibodies to human D-dimer.

Background: Commercially available D-dimer assays use antibodies against human D-dimer, with limited sensitivity and specificity data in companion animals.

Objectives: To evaluate the immunoreactivity of D-dimer in plasma of dogs, horses, and cats with commercially available antibodies to human D-dimer.

Animals: Plasma samples were collected from healthy dogs and horses, and from surplus feline plasma submitted for diagnostic purposes.

Analytical errors in nucleated red blood cell enumeration.

Background: Enumeration of nucleated red blood cells (NRBCs) in peripheral blood of dogs and cats is performed by manual counting during blood film evaluation. Automated methods have increased precision and accuracy; however, most analyzers cannot distinguish leukocytes and NRBCs. The Sysmex XN-V Series may distinguish NRBCs and leukocytes; however, analytical errors occur.

Prevalence of failure of passive immunity transfer in Australian non-replacement dairy calves.

Failure of passive immunity transfer (FPIT) increases the risk of morbidity and mortality in dairy calves. The prevalence of FPIT in dairy calves has generally been reported to be high, with FPIT estimated to occur in 38%-42% of Australian dairy calves. However, the focus of previous studies has been on replacement heifer calves.
