Encephalitic listeriosis was diagnosed in 2 adult llamas. Both had a multifocal suppurative encephalitis with mixed lymphocytic and neutrophilic perivascular infiltrates. Listeria monocytogenes was cultured from the brain stem of 1 llama using cold enrichment techniques; the other llama was culture negative. Formalin-fixed and paraffin embedded sections of(More)
Cytologic samples of popliteal lymph node, proximal femoral bone marrow, and the buffy coat fraction of blood were obtained from 56 dogs. The number of mast cells on 1 slide of each sample was determined by microscopic examination. Eleven of 46 slides of lymph node aspirate contained mast cells (range, 1 to 16; mean, 6.4; median, 5 mast cells/slide).(More)
BACKGROUND Immunocompromised patients are vulnerable to severe or complicated influenza infection. Vaccination is widely recommended for this group. This systematic review and meta-analysis assesses influenza vaccination for immunocompromised patients in terms of preventing influenza-like illness and laboratory confirmed influenza, serological response and(More)
Antiplatelet therapy remains a cornerstone of modern management of atherothrombotic vascular disease. For many years, aspirin has been the mainstay of initial antiplatelet drug management in coronary heart disease, while the need for inhibition of other platelet activation pathways has led to the development of various other antiplatelet drugs, such as(More)
A laboratory cat died 12 days after intraperitoneal inoculation of a 1 ml suspension containing 1.5 x 10(6) blood mononuclear cells from a Florida panther (Felis concolor coryi). Gross, histologic and ultrastructural investigations revealed the cause of death to be infection by Cytauxzoon felis, a protozoal parasite known to cause a rapidly fatal disease(More)
Vaccination of immunocompromised patients is recommended in many national guidelines to protect against severe or complicated influenza infection. However, due to uncertainties over the evidence base, implementation is frequently patchy and dependent on individual clinical discretion. We conducted a systematic review and meta-analysis to assess the evidence(More)
Clostridium spiroforme enterotoxin-mediated diarrhea can be a common cause of mortality among weanling age rabbits. Definitive diagnosis of this disorder requires detection of the causative enterotoxin. Using filtered cecal supernatant from necropsy specimens, antibodies to C. spiroforme and its products and Vero cells, a cytotoxicity assay was performed on(More)
The course of naturally acquired infection with feline immunodeficiency virus was monitored in a cat over an 18-month period after diagnosis. The cat was admitted with diarrhea, poor body condition, a bite wound abscess, gingivitis, chronic fever, and splenomegaly. The cat's condition improved after splenectomy and remained stable for approximately 15(More)
As many as 1 in 10 patients is harmed while receiving hospital care in wealthy countries. The risk of health care-associated infection in some developing countries is as much as 20 times higher. In response, in many global regions, increased attention has turned to the implementation of a broad program of safety research, encompassing a variety of methods.(More)
