The distribution and prevalence of Theileria buffeli in cattle in Queensland

The distribution and prevalence of Thelleria buffeli in Queensland cattle were investigated using serum samples and blood films collected primarily for brucellosis surveillance and tick fever diagnosis. Serums from 8654 cattle from 357 farms throughout Queensland were examined by an indirect fluorescent antibody test for antibody to T buffeli. In addition, 347 peripheral blood films collected from 147 farms in south-eastern Queensland were examined for piroplasms of T buffeli. The overall herd and animal prevalences for T buffeli were 75% and 41%, respectively. There was significant variation among regions in both herd and animal prevalences (P less than 0.001). Herd and animal prevalences were highest in the north and east decreasing westward. The results indicate that T buffeli is more widespread in Queensland than previously thought.     

Causes of disease and death from birth to 12 months of age in the Thoroughbred horse in Ireland

A retrospective study was carried out to investigate the causes of disease and death in a population of foals in Ireland during their first 12 months post partum. Foaling and veterinary records from 343 foals on four farms born between January 1, 2004 and May 30, 2008 were reviewed. Among 343 foals, 22 did not survive to 12 months of age. Over the five-year period, the incidence of stillbirth was 1.5% (5/343), mortality 5% (17/338) and overall morbidity was 88.5% (299/338). Morbidity was calculated to include all new conditions brought to the attention of the attending veterinary surgeon, no matter how minor. Of foals born alive: congenital abnormalities were the most common cause of death (35.3% 6/17 foals) followed by musculoskeletal trauma (5/17, 29.4%). Of 711 separate incidents of disease, 46.5% (331/711) were due to an infectious process, 25% (178/711) due to non-infectious musculoskeletal issues; and 14.9% (106/711) related to non-infectious gastrointestinal problems. Respiratory infection was the single most common disease accounting for 27.8% (178/711) of all disease incidents in this population. Findings from this study provide information regarding the causes and incidence of death and disease in the young Irish Thoroughbred population.     

Temporomandibular subluxation in the dog: A case report

Temporomandibular subluxation was diagnosed in a 2-year old Irish Setter dog. The presenting sign was frequent bouts of open jaw-locking. Tomographic evidence suggested that temporomandibular dysplasia was a factor in the aetiology of the condition. Surgical excision of rostral segments of the zygomatic arches effectively alleviated the clinical condition.
