The biology of Besnoitia besnoiti, the cause of bovine besnoitiosis, is poorly understood. Its definitive host is unknown, and information on potential intermediate hosts is scarce. In order to investigate potential definitive and intermediate hosts for European isolates of B. besnoiti, domestic dogs, cats, rabbits, guinea pigs (Cavia porcellus), gerbils(More)
BACKGROUND The transition period of dairy cows, around parturition and the onset of lactation, involves endocrine and metabolic changes to compensate for an increased energy requirement aggravated by reduced feed intake. Transition cows adjust to the resulting negative energy balance with the mobilization of lipids from the adipose tissues yielding(More)
This case report describes a three-year-old Friesian stallion with hypospadias. Physical examination revealed a ventrocaudal deviation of the shaft of the penis and an incomplete glans penis. The urethral opening was 4 cm in length, slit-like and had a mucous membrane covering. A short fold ran from the ventral aspect of the anus and ended with a(More)
Aquaculture is a burgeoning industry, requiring diversification into new farmed species, which are often at risk from infectious disease. We used a mesocosm technique to investigate the susceptibility of sharpsnout seabream (Diplodus puntazzo) larvae to potential environmental pathogens in seawater compared to control borehole water. Fish exposed to(More)
OBJECTIVE To compare ultrasonographic and histologic examination findings for eyes of animals with ocular diseases. DESIGN Retrospective case series. ANIMALS 116 eyes of 113 animals examined at 2 facilities. PROCEDURES Diseased eyes of animals were examined by means of ultrasonography, removed via enucleation or exenteration, then histologically(More)
A 12-month-old beagle presented for anorexia, pyrexia and vomiting. The dog had been treated intermittently with antibiotics and corticosteroids for inappetence and lethargy since five months of age. Previous laboratory abnormalities included macrocytosis and neutropenia. At presentation, the dog was lethargic, febrile and thin. Laboratory examination(More)
BACKGROUND Gastric acid suppressants frequently are used in cats with acid-related gastric disorders. However, it is not known if these drugs effectively increase intragastric pH in cats. OBJECTIVES To examine the effects of PO administered ranitidine and omeprazole on intragastric pH in cats and to compare the efficacy of once-daily versus twice-daily(More)
BACKGROUND Although gastroesophageal reflux (GER) often is assumed to be causative for upper gastrointestinal and respiratory signs in dogs, no attempts have been made to verify this assumption. OBJECTIVES To monitor esophageal pH with the Bravo pH system in healthy dogs and client-owned dogs displaying signs commonly attributed to GER. ANIMALS Seven(More)
OBJECTIVE Pathologic gastroesophageal reflux (GER) has been demonstrated experimentally in dogs, and it is suspected to occur naturally in dogs, yet its clinical significance is unknown. The aim of the study was to demonstrate clinical indicators of pathologic GER in dogs with idiopathic esophagopathies. MATERIALS AND METHODS Dogs with clinical signs(More)
An Argentine boa (Boa constrictor occidentalis) of 5 yr 7 mo of age was presented for respiratory problems and regurgitation. Radiographs revealed evidence of cardiomegaly and pneumonia. Blood smear examination revealed the presence of intracytoplasmic inclusion bodies in peripheral lymphocytes, consistent with inclusion body disease. Cultures of a tracheal(More)
