This review, aimed primarily at general practitioners, focuses on quality assurance/quality control principles for all three phases of clinical pathology testing: preanalytic, analytic, and postanalytic. Specific emphasis is placed on the preanalytic phase of diagnostic modalities for identifying neoplastic cells, specifically flow cytometry, PCR for(More)
The macrocyclic lactones are the only anthelmintics used to prevent heartworm disease, but it is very difficult to reproduce their in vivo efficacy against Dirofilaria immitis larvae in experiments in vitro. These assays typically measure motility, suggesting that paralysis is not the mode of action of the macrocyclic lactones against D. immitis. We(More)
Dear Editor, We are writing regarding the recently published article by Andrew Davis and Kerry Holcomb (2008) entitled “Intraerythrocytic inclusion bodies in painted turtles (Chrysemys picta picta) with measurements of affected cells”. In our diagnostic pathology services we see intraerythrocytic inclusion bodies similar to those described in this article(More)
BACKGROUND Although delays between blood sample collection and analysis are common in veterinary medicine, the effect of prolonged serum-clot contact time on serum glucose concentration is not well established and species differences have not been elucidated. OBJECTIVES The objective was to investigate the effect of storage time and temperature on serum(More)
A 2-tiered histologic grading scheme for canine cutaneous mast cell tumors (MCTs) is based on morphologic characteristics of neoplastic cells, including karyomegaly, multinucleation, nuclear pleomorphism, and mitotic figures. Aspirates from MCTs may provide the same information more quickly, inexpensively, and less invasively. This study used these criteria(More)
The purpose of this document is to educate providers of veterinary laboratory diagnostic testing in any setting about comparative testing. These guidelines will define, explain, and illustrate the importance of a multi-faceted laboratory quality management program which includes comparative testing. The guidelines will provide suggestions for implementation(More)
Although elasmobranch species are increasingly displayed in public aquaria, knowledge of disease in wild and captive elasmobranchs, as well as the agents involved, remains limited, and descriptions are often incomplete. This report describes papillomatous skin lesions in a juvenile giant guitarfish Rhynchobatus djiddensis associated with intranuclear viral(More)
Host genetic resistance against disease-causing pathogens can be enhanced through family-based selective breeding. At present, there is an incomplete understanding of how artificial selection of fish alters host physiology and response following pathogen exposure. We previously reported the generation of selectively-bred rainbow trout Oncorhynchus mykiss(More)
