Equine blood cultures: Can we do better? Blood culture is considered the gold standard test for documenting bacteraemia in patients with suspected bacterial sepsis in veterinary and human medicine. However, blood culture often fails to yield bacterial growth even though the clinical picture is strongly suggestive of bacterial sepsis, or contaminating organisms can overgrow the true pathogen, making accurate diagnosis and appropriate management of this life-threatening condition very challenging. Methodology for collecting blood cultures in equine medicine, and even in human hospitals, is not standardised, and many variables can affec...

Establishment of a protocol for preventive vaccination against equine insect bite hypersensitivity. Insect bite hypersensitivity (IBH) is a seasonal dermatitis of horses caused by IgE-mediated reactions to bites of Culicoides midges characterized by an imbalance of T-cell subsets. Iceland is free of the causative species but the prevalence of IBH in exported Icelandic horses is especially high. We have shown that intralymphatic (i.l.) vaccination with r-Culicoides allergens in Aluminum hydroxide (alum) and monophosphoryl lipid A (MPLA) adjuvants induces a desired Th1/regulatory T-cell response. The aim of this study was to compare i.l. to subcutaneous (s.c.) injection. Twelve healthy Iceland...
Survey on the recognition, attitudes, and experience of horse owners during episodes of equine colic in Rio Grande do Norte, Brazil. Horse owners are crucial in recognizing colic because they are responsible for identifying the signs of colic and deciding whether to seek veterinary intervention. Common reasons for delayed response to clinical issues include lack of understanding or knowledge of the subject and difficulty in recognizing subtle clinical signs of abdominal pain. Examining horse owners' basic knowledge of colic, their motivations, obstacles in seeking veterinary care, and their responses to the various clinical symptoms manifested during colic will identify current knowledge gaps and decision-making barriers. T...
