In Vivo Biofilm Formation of Pathogenic spp. in the Vitreous Humor of Horses with Recurrent Uveitis.

Equine recurrent uveitis (ERU) causes painful inflammatory attacks and oftentimes blindness in the affected eyes. The disease is considered a late sequela of systemic leptospirosis. The most effective therapy is the surgical removal of the vitreous (vitrectomy), which is not only therapeutic, but provides vitreous material that can be assessed diagnostically.

The topographic and systematic anatomy of the alpaca stomach.

The gastric anatomy of the alpaca (Vicugna pacos) is adapted to the physiological process of ruminating and the degradation of plant cell wall contents to a great extent. Most alpaca husbandries consist of only few animals and with the still increasing number of alpacas worldwide the number of persons who are responsible for these animals is increasing as well. Despite this, little research has been done with regard to the clinical anatomy of the stomach of alpacas.

Adaptive Anatomical Specialization of the Intestines of Alpacas Taking into Account their Original Habitat and Feeding Behaviour.

The gastrointestinal tract of the alpaca (Vicugna pacos) is most efficiently adapted to its habitat at high altitudes. Alpacas, just like ruminants, feed on hardly digestible forage. However, it has been demonstrated that the anatomy of the camelid digestive tract has developed independently of ruminants and not in homology to them.

[Morphological investigations of deep sole ulcers in cattle. Part 2: Toe ulcers, white line disease in the heel and changes due to inappropriate weight bearing and deficient claw care].

Objective: To demonstrate the morphology of pathological changes to the inner structures of the claw in cases of toe ulcers, white line disease in the heel and changes due to inappropriate weight bearing and deficient claw care.

Material And Methods: Hind limbs of 55 cows displaying external signs of complicated sole ulcers were examined externally and internally. To examine the samples internally, a sagittal section was performed.

[Morphological investigations of deep sole ulcers in cattle. Part 1: The complicated Rusterholz ulcer].

Objective: In the context of a larger study on morphological changes of deep sole ulcers, claws with Rusterholz ulcer (RU) were investigated to describe the varied pathological changes of the RU.

Material And Methods: Hind limbs of 55 cows displaying external signs of complicated sole ulcers were examined externally and internally. To examine the samples internally, a sagittal section was performed.

Prevalence and characterization of small tympanic bone spicules and drumstick-like hyperostotic tympanic bone spicules in the middle ear cavity of dogs.

Rounded, sessile, hyperattenuating structures detected in computed tomography (CT) studies of canine tympanic bullae have been termed "otoliths." These have been proposed to represent dystrophic mineralizations or heterotopic bone formations in the middle ear that are potentially related to chronic otitis media. Aims of the current study were to describe the prevalence, macroscopic, and histological features of structures consistent with "otoliths" in the canine tympanic cavity.

Topographic and age-dependent distribution of subchondral bone density in the elbow joints of clinically normal dogs.

Objective: To investigate topographic and age-dependent adaptation of subchondral bone density in the elbow joints of healthy dogs by means of computed tomographic osteoabsorptiometry (CTOAM). Animals-42 elbow joints of 29 clinically normal dogs of various breeds and ages.

Procedures: Subchondral bone densities of the humeral, radial, and ulnar joint surfaces of the elbow relative to a water-hydroxyapatite phantom were assessed by means of CTOAM.

Mapping subchondral bone density of selected donor and recipient sites for autologous osteochondral transplantation in the canine stifle joint using computed tomographic osteoabsorptiometry.

Objective: To characterize donor and recipient sites for autologous osteochondral transplantation (AOT) in the canine stifle joint with respect to maximal subchondral bone density (mSBD).

Study Design: Descriptive laboratory study.

Sample Population: Femora (n=15) of dogs (>20 kg).

Accuracy of conventional radiography and computed tomography in predicting implant position in relation to the vertebral canal in dogs.

Objective: To compare the accuracy of radiography and computed tomography (CT) in predicting implant position in relation to the vertebral canal in the cervical and thoracolumbar vertebral column.

Study Design: In vitro imaging and anatomic study.

Animals: Medium-sized canine cadaver vertebral columns (n=12).

Mapping of split-line pattern and cartilage thickness of selected donor and recipient sites for autologous osteochondral transplantation in the canine stifle joint.

Objective: To characterize donor and recipient sites for autologous osteochondral transplantation in the canine stifle joint with respect to split-line pattern and cartilage thickness.

Study Design: In vitro study. Sample Population- Stifle joints (n=30) of dogs >20 kg.

Automatic image registration of three-dimensional images of the head of cats and dogs by use of maximization of mutual information.

Objective: To validate mutual information criterion as a ready-to-use technique for automated alignment (ie, registration) of 3-dimensional (3-D) multimodal image data of the head of cats and dogs.

Sample Population: Corresponding 3-D magnetic resonance imaging (MRI) and computed tomography (CT) brain scans of a 6-month-old Doberman Pinscher with a brain cyst; CT images of the head of a European shorthair cat with a meningioma before and immediately, 3, and 6 months after surgical resection; and CT and corresponding stacked anatomic cryosection images of the entire head of a 2-year-old sexually intact female Beagle.

Procedure: All images were matched retrospectively by use of an in-house computer program developed on the basis of a mutual information image registration algorithm.
