Ultrasound has become more common in the investigation of the podotrochlear apparatus in the horse and the use of more sensible scanheads improved the quality of the images. This study shows six examples of the ultrasound anatomy of the distal podotrochlear apparatus in the transcuneal view performed with three different scanheads. The presented transcuneal scans of the podotrochlear apparatus of an 18 months old warmblood foal have been established post mortem on isolated feet. Modus of registration was real-timemotion, linear- and sectorscanheads working at 7.5 (linear) and 7.5 (microconvex) and 3.5 (convex) MHz were used. The echoanatomic structures of the soft tissue and bony surfaces in the distal podotrochlear region are compared by six images. The combination of the different scanheads permits an improved complete visualisation in this area. Therefore these ultrasound pictures show that ultrasonography is an useful complementary investigation method that enables to precise the diagnosis [less ▲]

Following international agreements and european legislation, risk analysis has become a systematic approach to control the food chain safety. The microbial risks in the food chain and their consequences for public health can be assessed and managed more effectively. This paper gives a general description of the risk analysis principles based on the Codex Alimentarius commission. This work highlights the advantages and disadvantages of risk analysis and also treats the problems to achieve a complete “farm to fork” model. Salmonella in different food types is taken as an example to illustrate quantitative risk assessment. Two models concerning eggs and broiler chickens developed by the World Health Organization/Food and Agriculture Organization consortium and a third model concerning pigs developed by the Veterinary Laboratories Agency of the United Kingdom are described. An analysis of the methods used for the construction of these two models is also presented. The interest of these three models is that they also include risk management options to limit the spread of food-borne infections. They also describe the final risk for a population following consumption of foodstuffs. These models are valuable tools for health officials but also for feed industry. [less ▲]

The erythrocyte, as an oxygen carrier, is submitted to areas where oxidative stress is important. The maintenance of the structure and fluidity of its membrane is essential to its function. Indeed, oxygen must diffuse through the membrane and the deformability of the cell is essential to its progression through capillaries. The structure and, as a consequence, the fluidity of the membrane influence these properties. The red blood cell presents antioxydant capacities, but in some cases, free radical production is increased and exceeds antiradical defences leading to irreversible defects of the membrane, and, as a consequence, of its function. Horse erythrocyte seems to be more sensitive to oxidative stress than other species and resulting hemorheological changes could have tissular and organic consequences. [less ▲]

An ovarian cyst is classically defined as a fluid-filled space larger than 24 mm, that can persist for more than 7 to 10 days in the absence of a corpus luteum. The frequenc y of this pathology is between 7 to 15%. Contrary to the follicular cyst, the luteinised follicular cyst is characterized by the presence in its periphery of a luteal tissue. The ovarian cyst is a dynamic structure. Its presence doesn't interfere with the follicular waves but can modify their characteristics. An ovarian cyst results from or induces an absence of ovulation. Ovarian cyst diagnosis and especially the differential diagnosis between follicular and luteal cysts necessarily imply the use of ultrasonography to clearly identified their diameter and thickeness. The ultrasonography sensibility is better than that of transrectal palpation. Progesteronemia interpretation supposes the preliminary definition of a threshold. Behavioural(anoestrus or nymphomany), uterine(tonicity of the uterine horns) or vaginal (mucus) abnormalities can help to direct the diagnosis. [less ▲]

The Tasmanian Devil is the largest carnivorous marsupial of Australia. Since 1996, this species faces an emerging transmissible and fatal disease that is characterized by eruption of tumors on the face and the neck. Having carried 75.000 animals off in only 8 years, the Tasmanian Devil’s transmissible tumor dramatically threatens the survival of the species, which would have disastrous ecological consequences because of its key role as a predator and as a scavenger. The following text gathers the information available on the features of the disease and brings to the light its astonishing etiology and mode of transmission [less ▲]

Selenium and iodine deficiencies are frequently present in cattle in Europe with a negative impact on animal health, reproduction and production. Deficiencies in animals also influence human health owing to consumption of their products. These deficiencies must be correctly diagnosed in order to avoid lack of diagnosis or wrong diagnosis. Since there are many interactions between nutrients, a nutritional approach only is of limited interest. Therefore, the diagnosis based on samples obtained on the animals is more reliable. Clinical signs of selenium and iodine deficiencies are rarely pathognomonic. Laboratory analyses are thus necessary to confirm the diagnosis. The present review relates the principal clinical signs of selenium and iodine deficiencies and the confirmation of the deficiency by the measurements of different nutritional and functional markers available for cattle, either on blood, milk, urine or tissues. Finally, a protocol for the diagnosis of selenium and iodine deficiencies is proposed [less ▲]

Foodborne disease have an important impact on the public health. In Europe and in the USA, Salmonella and Campylobacter are the two main bacterial causes because of their presence in the intestinal tract of poultry, pig and beef. For the monitoring of the bacterial contamination of food, the enumeration of certain groups or species of bacteria of intestinal origin is an alternative to the detection of the pathogenic microorganisms. They can be used as index indicating the possible presence of pathogenic agents having a similar ecology, or as indicators announcing the non-observance of the good practices. The most used are the total plate counts, E. coli and the Enterobacteriaceae. During meat production, they are counted at the level of environment, along the food chain, on carcasses at the slaughterhouse, on carcasses and in meat, in plants and distribution. Various surveys are carried out by the producers of food and the authorities for the control of the auto-control, the national inspection plans or to determine the national baseline. [less ▲]

The degenerative osteoarthritis is a common source of disease in the horse, causing pain and leading finally to the destruction of the cartilage in the diarthrodial joints. The synovial membrane is a constitutive element of the joint, but often neglected due to its less obvious alterations, despite its crucial role. This review of literature considers the embryology, the histology of synoviocytes in vivo and in vitro, gives information about the production of inflammatory mediators, degrading enzymes, free oxygen radicals, about the composition of the synovial fluid and the interaction with chondrocytes. The number of studies on equine synoviocytes in osteoarthritis is very restricted, therefore we included studies in other species and other types of joint diseases to achieve a more complete image of the complex, interdependent and mutual acting mechanisms.

Several scientific studies revealed that substances with hormonal (or antihormonal) activity are widely distributed in the environment as well as in food, either as natural constituents (as phytoestrogens), or as substances of anthropogenic origin (for example, Several observations concerning both the wild fauna and humans indicate that these products with hormonal activity are endocrine disruptors. Numerous ecotoxicological studies evidenced important disturbances of the fertility of the wild fauna in zones contaminated by pesticides. In humans, epidemiological studies revealed a significant increase of certain cancers (among others, that of the testicles) and a decrease of the male fertility. Substances with estrogenic activity are often considered, but other hormonal effects are more and more frequently discovered (i.e. anti-androgenic). Numerous worries appear concerning the long-term effects on human health linked to a chronic exposure to these substances by food ingestion. It is urgent to review, not only on the actual contamination of our food by endocrine disruptors (in terms of identification and quantification of every individual chemical), but also the potentially toxic activity of food containing a mixture of contaminants present at levels below their individual toxicity threshold.

The aim of this study was to assess the accuracy of judging age from teeth, with standard aging guides, of mares from 2 to 20 years old registered in the Belgian draft horse stud-book. The replacement of the deciduous incisors by permanent teeth occurred when expected as the disappearance of the infundibulum on the permanent lower intermediate incisors. The disappearance of the infundibulum was however observed until 16 months earlier than expected on the central incisors and until 18 months later on the corner incisors with 64 % and 50 % of the concerned mares respectively. The modifications of the shape of the occlusal tables from oval to round occurred from 1 to 4 years earlier than expected. The risk to attribute an older age than the true age during the so called round period is lower when taking into account the disappearance of the cup cement leaving only an enamel spot on the occlusal table surface. The modifications of the shape of the incisor tables from round to triangular and to biangular was also observed earlier than expected but only with the central and intermediate incisors, not with the corner incisors. The measurement on photographs of the profile angle of the corner incisors confirmed that this angle decreases with age from about 134 degrees at about 5 years to about 72 degrees at 20 years. Statistical analyses of the differences between real ages and those estimated on pictures by a college of three experts, show that ageing horses from their dentition is more accurate for animals of 8 years old or less, than for older ones. For those animals, the overestimation was about 10 % of the real age. [less ▲]

Certains Escherichia coli producteurs de Shigatoxines (STEC) sont responsables de toxi-infections d’origine alimentaire qui se traduisent par des diarrhées mais aussi par des syndromes plus graves pour l’homme comme le syndrome hémolytique urémique pouvant provoquer la mort. Il s’agit d’agents zoonotiques dont le réservoir principal est le bovin et les autres ruminants. Les principaux modes de transmission des infections à STEC à l’homme sont la consommation d’aliments contaminés (viande de boeuf peu cuite, produits laitiers non pasteurisés), la transmission de personne à personne, l’ingestion d’eau contaminée et le contact avec des animaux (notamment les bovins) et leur environnement. Les facteurs de virulence des Escherichia coli producteurs de Shigatoxines sont principalement les protéines codées par un îlot de pathogénicité, « Locus of Enterocyte Effacement », impliquées dans la formation de la lésion d’attachement et d’effacement et de la diarrhée et les toxines de Shiga codées par des bactériophages et impliquées dans les syndromes extraintestinaux. La souche de STEC du sérotype O157:H7 est responsable d’épidémies dans le monde causant des milliers de malades et des dizaines de morts. De nombreuses méthodes de diagnostic ont été développées pour identifier ce pathogène à partir des aliments. Elles regroupent des méthodes de bactériologie classique, des méthodes immunologiques et des méthodes moléculaires. Des mesures d’hygiène sont particulièrement importantes pour éviter la contamination des animaux à la ferme et celle de la viande à l’abattoir. Enfin, des modèles d’évaluation du risque ont été développés notamment afin de modéliser le comportement des STEC dans l’aliment. [less ▲]

Infectious respiratory diseases also called ‘cat flu’ are nowadays one of the most relevant areas of feline medicine. Epidemiologic surveys revealed that 80% of the cases are due to feline calicivirus and Felid herpesvirus 1 (FeHV-1). FeHV-1 is an alphaherpesvirus that has a worldwide distribution in cat population. It is responsible for feline viral rhinotracheitis. This disease can be acute, chronic or latent. It is characterized by fever and respiratory or ocular signs among which conjunctivitis and keratitis are the most common. Severe cases can cause complete blindness of the cat mostly following repetitive reactivations. Latent viral carriers are epidemiologically important because they are the main source of infection to susceptible cats. Nowadays no vaccine can prevent infection. At best, available vaccines help to reduce clinical signs but fail to prevent establishment of latency or reactivation. Consequently, feline viral rhinotracheitis still represents a major problem in domestic cats. This review focuses on the current knowledge about feline viral rhinotracheitis and its etiologic agent, FeHV-1. [less ▲]

The lipopolysaccharide (LPS) is a major component of the surface of the Gram negative bacteria. The LPS is composed of three separately synthesized entities: the lipid A, the core oligosaccharide and the O antigen, that will be linked together after their respective synthesis. The lipid A, embedded inside the outer membrane, is the proximal part of the LPS and the core is the medial part, whereas the O antigen represents the distal part free in the external environment. Amongst the Enterobacteriaceae family, the lipid A is structurally highly conserved and the variation in the structure of the core oligosaccharide is limited whereas the O antigen is the hypervariable region. Diverse biological activities have been associated with LPS, amongst which the endotoxinic activity carried by the lipid A, and the strain immunogenic specificity carried by the O antigen. In this review manuscript we summarize the state of knowledge on the structures and biosynthesis of the different components of the LPS of Escherichia coli and on their respective roles in the virulence of pathogenic bacteria.
