Ultrasonographic findings in the bladder of cattle at different stages of evolution of bovine enzootic hematuria in Brazil.

Despite the diagnostic capacity of ultrasonography (US) in cases of bovine enzootic hematuria (BEH), it has been underused in the medical clinic for ruminants. Studies comparing ultrasound findings in healthy animals (HA) with subclinical (SCH) and clinical (CH) BEH are scarce in the literature. As a result, the present work aims to describe the US findings of cattle at different stages of BEH evolution, evaluating the diagnostic capacity and precocity of the technique.

Molecular and Cellular Evaluation of Horses With Summer Pasture Associated Asthma Syndrome.

Equine asthma is an airway disease that affects a large number of horses annually leading to considerable economic losses in the horse industry. Despite advances in research in this area, there is still a lack of information on its etiology and molecular characterization in pasture associated asthma. The objective of the current study was to characterize the inflammatory disease of lower airways in horses maintained on pasture through cytologic and immunologic profile during the summer in a tropical environment by analysis of the gene expression of Th1 cytokines (IFN- λ, IL-8), Th2 cytokines (IL-4 and IL-5), and pro-inflammatory cytokines (IL-1, TNF-α) in the bronchoalveolar lavage (BAL) fluid in healthy and asthma horses on pasture.

Serum proteins and electrophoretic profile in horses undergoing crotalid venom hyperimmunization.

Indisputably, the use of antivenoms for the treatment of snakebite envenoming is beneficial for the victims. However, there are few studies addressing the effect of long-term hyperimmunization in inoculated horses. It is known that the injection of snake venoms and adjuvants leads to local and systemic reactions in horses, but little is known about the response of inflammatory proteins.

Evaluation of acquired passive immunity in mule foals up to 60 days of age.

Ten mule foals were used to investigate serum IgG concentration. Blood was collected from mares and foals on the day following parturition (D1), at 48 and 72 hr after birth (D2 and D3), and on D7, D14, D21, D28, D35, D42, and D60. Serum IgG concentration was determined by zinc sulfate turbidity test and was above 400 mg/dl at all time points, except for one foal on D2.

Association between exercise-induced pulmonary hemorrhage and inflammatory airway disease in polo ponies.

The respiratory system is essential for health and high athletic performance in horses. Respiratory diseases have been recognized as having a major impact on training equine animals and are commonly cited as the second most common cause of wasted training time. Inflammatory airway disease (IAD) is an important cause of poor performance in young racehorses.
