The objectives of this study were (1) to evaluate the indications, complications and outcomes of multiple red cell transfusions (MrcTs) in cats; of these cats (2) to describe those that received massive transfusion and (3) compare them with those who received MrcTs over a longer time course. Twenty-seven cats were identified which received a total of 110 transfusions, with a median of three transfusions (range 3-15) per cat. The transfusions consisted of 47 units of whole blood and 63 units of packed red blood cells. The median age of cats was 6 years (range 6 months to 15 years). Cats were hospitalized for a median of 6 days, with a range of 1-38 days. No acute transfusion reactions were documented, although due to the critical nature of the cats, they may not have been appreciated. Sixteen cats survived to discharge and 11 died or were euthanased. Indications (and % survival) for transfusions included bone marrow failure (n=8; 50%); surgical loss (n=4; 100%), sepsis (n=3; 0%), neoplasia (n=3; 33%), acute renal failure (n=3; 66%), trauma (n=2; 100%), gastrointestinal bleeding (n=1; 100%), and cats with multiple disease processes (n=3; 33%). MrcTs are well-tolerated in cats and may be associated with a favorable outcome. 相似文献

OBJECTIVE: To evaluate canarypox-vectored equine influenza virus (EIV) vaccines expressing hemagglutinins of A/equine/Kentucky/94 (vCP1529) and A2/equine/Ohio /03 (vCP2242) for induction of antibody responses against canine influenza virus (CIV) in dogs. ANIMALS: 35 dogs. PROCEDURES: Dogs were randomly allocated into 4 groups; group 1 (n = 8) and group 2 (9) were inoculated SC on days 0 and 28 with 1.0 mL (approx 10(5.7) TCID(50)) of vCP1529 and vCP2242, respectively. Dogs in group 3 (n = 9) were inoculated twice with 0.25 mL (approx 10(5.7) TCID(50)) of vCP2242 via the transdermal route. The 9 dogs of group 4 were control animals. All dogs were examined for adverse reactions. Sera, collected on days -1, 7, 13, 21, 28, 35, and 42, were tested by hemagglutination inhibition (HI) and virus neutralization (VN) assays for antibodies against CIV antigens A/Canine/FL/43/04-PR and A/Canine/NY/115809/05, respectively. RESULTS: Inoculations were tolerated well. The HI and VN antibodies were detected by 7 days after primary inoculation. Most dogs of groups 1 and 2 and all dogs of group 3 had detectable antibodies by 14 days after initial inoculation. The second inoculation induced an anamnestic response, yielding geometric mean HI titers of 139, 276, and 1,505 and VN titers of 335, 937, and 3,288 by day 42 (14 days after booster inoculation) in groups 1, 2, and 3, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: Canarypox-vectored EIV vaccines induce biologically important antibodies and may substantially impact CIV transmission within a community and be of great value in protecting dogs against CIV-induced disease. 相似文献

BACKGROUND: Based upon alloantibodies produced after sensitizing dogs with transfused blood, more than a dozen blood group systems have been recognized thus far, and some have been classified as dog erythrocyte antigens (DEA). HYPOTHESIS: A new canine red cell antigen was suspected, based on the development of specific alloantibodies in a Dalmatian previously sensitized by blood transfusions. ANIMALS: Twenty-six Dalmatians (including 1 Dalmatian in need of blood compatibility studies); 55 canine blood donors. METHODS: Serologic tests, including blood typing, crossmatching, and direct Coombs' test were performed by standard tube techniques and a novel gel column technology adapted from human blood banking. RESULTS: By day 40 after transfusion of an anemic Dalmatian, all major crossmatch tests to 55 non-Dalmatian dogs were incompatible. The 2 initial donors, who were compatible before transfusion, were also now incompatible, suggesting the development of an alloantibody to a common red cell antigen. No siblings were available, but 4 of 25 unrelated Dalmatians were crossmatch compatible, suggesting that they were missing the same red cell antigen. The patient was blood typed DEA 1.1, 3, 4, and 5 positive, but DEA 7 negative. Further blood typing and crossmatching results did not support an association to any of these known blood types. The alloantibodies produced were determined to be of the immunoglobulin G class. CONCLUSIONS AND CLINICAL IMPORTANCE: Based upon the identification of an acquired alloantibody in a Dalmatian, a presumably new common blood type named Dal was identified. Dalmatians lacking the Dal antigen are likely at risk of delayed and acute hemolytic transfusion reactions. 相似文献

A 6-year-old Dachshund was presented with a 2-day history of lethargy, anorexia and cutaneous erythema, edema, and multifocal erythematous papules affecting the ventral abdomen, axillae, and groin. Microscopic examination revealed a sterile neutrophilic dermatitis resembling Sweet's syndrome; however, extracutaneous lesions were not present. The condition responded rapidly to corticosteroid therapy. 相似文献

The use of a molecular assay for quantifying conidia of Ophiognomonia clavigignenti‐juglandacearum, the fungal pathogen responsible of butternut canker, was investigated. Purified DNA from conidia collected on glass fibre filters of a passive rain collectors was quantified using a TaqMan real‐time quantitative polymerase chain reaction (qPCR) assay. The qPCR assay could specifically discriminate the target species from all other North American known species of Ophiognomonia, and it was sensitive enough to repeatedly detect one conidium. A linear relationship between numbers of conidia and qPCR Ct values was determined, and used to assess the sporulation of the pathogen under trees that were released to promote their vigour. In total, 977 samples of field‐captured conidia from 49 trees, at two locations, and from two successive growing seasons were analysed. No significant difference of sporulation was observed under control and release treatments. However, our results demonstrated that qPCR assay was reliable for detecting and quantifying O. clavigignenti‐juglandacearum from environmental samples, which will be useful to assess further control methods for this disease. 相似文献
