This study was conducted to compare the pathogenesis of acute and latent infections with closely related bovine herpesvirus types 1 (BHV-1) and 5 (BHV-5) in their natural host. Two groups of eight calves were inoculated intranasally with BHV-1 or BHV-5. Although BHV-1 and BHV-5 similarly replicate in the nasal mucosa after inoculation, both viruses differ markedly in their ability to cause disease, BHV-5 being responsible of some fatal encephalitis while BHV-1 inducing rhinotracheitis. Virus isolation and immunohistochemistry demonstrated that BHV-5 replicates extensively in neurons of the central nervous system (CNS) and in respiratory cells of lungs, tracheal and nasal mucosae. Invasion of the CNS likely occurs through the trigeminal and olfactory pathways. Both groups developed cross-neutralising antibodies during this experiment suggesting partial clinical cross-protection afforded by the two infections. Three months after primary infection, experimental reactivation showed that BHV-5 was able to establish latency in the trigeminal ganglia but also the CNS of surviving calves. Moreover, laboratory findings suggested that BHV-5 could also persist in the tracheal and nasal mucosae. These results indicate that, after primary infection, BHV-1 and BHV-5 displayed similar biological features and consequently need to be considered together for the control of BHV-1 infection.

Navicular bones from the four limbs of 95 horses, classified in 9 categories, were studied. The effects of age on navicular bone morphometry and histomorphometry were estimated, after adjustment of the data to even out the effects of front and rear limbs, morphometrical type, sex, weight, and size. All the external measurements of the navicular bone decreased significantly with increasing age. From the histomorphometrical data, cortical bone volume decreased with age in most horses, whereas cancellous bone volume and, in particular, the marrow spaces increased. The increase in the cancellous bone volume could have resulted from tunnelling of the internal part of the cortex, which converted it progressively into a porous trabecular-like structure. Trabecular bone volume also decreased with age and the trabecular lattice changed dramatically to become disconnected in aged horses. These observations corresponded closely to those reported for ageing of the skeletal system in humans. However, in sporting horses, the navicular cortical bone volume increased with age and the cancellous bone volume decreased. Exercise appeared to have decreased bone resorption and increased bone formation at the endocortical junction. The cancellous bone architecture was also improved. in that the trabecular lattice and trabecular bone volume remained unchanged in aged sporting horses. Our findings confirmed that exercise may be good practice to prevent age-related bone loss. [less ▲]

Mast cell (MC) phenotypes may vary with respect to tissue site, sensitivity to degranulating agents, dependency on T lymphocytes and, above all, the composition of their granules. Proteinases (either trypsin-like or chymotrypsin-like) are granule constituents which provide an important means of distinguishing subtypes of MCs in man and rodents. The purpose of this study was to compare the distribution of MC trypsin-like protease (tryptase) in a variety of bovine tissues with the aim of examining MC heterogeneity. Tryptase was found in MCs regardless of their location within tissues. With respect to tryptase content, bovine MC distribution resembled more that of human and canine tissues than that of mice and rats. Comparison of the results yielded by enzyme- and immuno-histochemical staining suggested that a tryptase-negative, dual-specific chymase-positive MC subset occurred, at least in duodenal lamina propria, around bronchioles and within alveolar septa. The study also suggested that monoclonal antibodies raised against human tryptase can be used for quantitation of bovine tryptase in biological fluids; this offers a promising tool for evaluating the role of MC activation in disease.

Navicular bones from the 4 limbs of 95 horses, classified in 9 categories, were studied. The anatomical bases were established for the morphometry of the navicular bone and its variations according to the category of horse, after corrections were made for front or rear limb, sex, weight, size and age. In ponies, navicular bone measurements were smallest for light ponies and regularly increased with body size, but in horses, navicular bone dimensions were smallest for the athletic halfbred, intermediate for draft horse, thoroughbreds and sedentary halfbreds and largest for heavy halfbreds. The athletic halfbred thus showed reduced bone dimensions when compared with other horse types. Navicular bones from 61 horses were studied histomorphometrically. Light horses and ponies possessed larger amounts of cancellous bone and less cortical bone. Draft horses and heavy ponies showed marked thickening of cortical bone with minimum intracortical porosity, and a decrease in marrow spaces associated with more trabecular bone. Two distinct zones were observed for the flexor surface cortex: an external zone composed mainly of poorly remodelled lamellar bone, disposed in a distoproximal oblique direction, and an internal zone composed mainly of secondary bone, with a lateromedial direction for haversian canals. Flexor cortex external zone tended to be smaller for heavy ponies than for the light ponies. It was the opposite for horses, with the largest amount of external zone registered for draft horses. In athletic horses, we observed an increase in the amount of cortical bone at the expense of cancellous bone which could be the result of reduced resorption and increased formation at the corticoendosteal junction. Cancellous bone was reduced for the athletic horses but the number of trabeculae and their specific surfaces were larger. Increased bone formation and reduced resorption could also account for these differences. [less ▲]

The scoring system based on the different types of navicular distal border canals is a good method to quantify and relativise the anomalies in number, shape and localisation of the canals. The distal border score varies significantly with the limb (fore or rear), the morphological type, the gender and the age of the horse. These anatomical variations are of importance and must be taken into account when examining a suspect bone. The score is larger for the fore navicular bone than for the rear. It could be interesting to compare both scores: rear navicular bone score is generally equal to half (or slight less) that of the fore. The score is larger for heavy types of horses and ponies (drafthorse, heavy halfbreds and Fjords). This phenomenon could be related to a larger pressure within the distal interphalangeal joint. The score is lower for the athletic half bred than for other halfbreds. This could be the result of the changes in bone architecture induced by exercise and particularly bone densification. The score is lower for the female than for the male. We think that navicular bone quality is better for the female and this idea corroborates that of other authors that consider that the risk to develop navicular disease is smaller for the female than for the male. The score increases with age. it is particularly small in young horses less than two years old and then increases strongly. This phenomenon is to be related to the progressive development, in the first year of life, of the groove between articular cartilage and distal impar ligament, canals developping only later one. In athletic horses, the score is higher between 7 and 12 years of age. During this time, we also observe more degenerative changes within the navicular bone, which could mean that bone is of lesser quality. [less ▲]

Navicular bones collected from the four limbs of 95 sound horses were studied. The anatomic bases have been laid down about morphometry of the navicular bones and their variations according to limbs, after corrections have been made for morphologic type, gender, weight, size and age. All the dimensions of the navicular bone (except for the thickness) were larger in the fore limb. This phenomenon probably reflects an attempt to compensate for the greater forces exerted upon the fore limbs during exercise and at rest. Navicular bones collected from the four limbs of 61 sound horses were studied and the anatomic bases were described for histomorphometry of the fore and rear navicular bones. Fore navicular bones possess less cortical bone at the level of the articular surface, as well as at the level of the flexor surface and proximal border, but larger amounts of cancellous bone. Articular and flexor surface cortical bone show a larger porosity in the fore navicular bones and a larger amount of mineralized cartilage. The mineralized portion for distal impar- and collateral sesamoidean ligaments are also larger for the fore navicular bones. Two distinct zones are observed for the flexor surface cortex that have never been reported in the literature before: an external zone, which is mainly composed of poorly remodelled lamellar bone, arranged in a disto-proximal oblique direction, and an internal zone, which is mainly composed of secondary bone, with a latero-medial direction of Haversian canals. Bone architecture is discussed with regard to the mechanic load, encountered by the bone during locomotion. [less ▲]

This study is a part of a work to design a radiographical method to objectively define the conformation of an equine digit and to assess the individual appropriate trimming of a horse. Various angles were measured directly from the phalangeal bones. The authors observed that the bone relief of the sesamoid ligament insertions on the proximal phalanx was an essential landmark to determine the phalangeal alignment. The same angles were measured from specific radiographs and made it possible to quantify the rotation imposed to the proximal phalanx. The authors also noticed that the phalangeal rotation had little influence on the radiographic image of articular asymmetry. [less ▲]
