Doping in Racing Pigeons (): A Review and Actual Situation in Belgium, a Leading Country in This Field.

Pigeon racing is a sport in which trained homing pigeons () are released between 60 and 1200 km from their loft and then have to return home as quickly as possible. The first race was held in 1818 in Belgium and since then, Belgium has led the world in pigeon breeding. Unfortunately, as in other sports, doping has become a major issue and doping controls have been implemented.

Effects of a Single Opioid Dose on Gastrointestinal Motility in Rabbits (): Comparisons among Morphine, Butorphanol, and Tramadol.

The aim of this study was to evaluate and compare the effects of single doses of butorphanol, morphine, and tramadol on gastrointestinal motility in rabbits () using non-invasive imaging methods, such as radiographic barium follow through and ultrasonographic contraction counts. Time-lapse radiographic and ultrasound examinations were performed before and after a single intramuscular dose of 5 mg kg butorphanol, 10 mg kg morphine, or 10 mg kg tramadol. Pyloric and duodenal contraction counts by ultrasonography and radiographic repletion scores for the stomach and caecum were analysed using a mixed linear model.

In vitro and in vivo assessment of eprociclovir as antiviral treatment against testudinid herpesvirus 3 in Hermann's tortoise (Testudo hermanni).

Tortoises belonging to the Testudinidae family are infected by Testudinid herpesviruses. Testudinid herpesvirus 3 (TeHV-3) is considered the most pathogenic and affects several tortoise species, particularly those from the Testudo genus. As most species of this genus are endangered contribute to ecological concerns over this virus.

Influence of a single dose of buprenorphine on rabbit (Oryctolagus cuniculus) gastrointestinal motility.

Objective: To establish a noninvasive imaging protocol for rabbit gastrointestinal transit evaluation. To assess the effect of a single injection of buprenorphine on the digestive transit of rabbits via this new technique.

Study Design: Prospective, parallel study.

The Genome of a Tortoise Herpesvirus (Testudinid Herpesvirus 3) Has a Novel Structure and Contains a Large Region That Is Not Required for Replication In Vitro or Virulence In Vivo.

Unlabelled: Testudinid herpesvirus 3 (TeHV-3) is the causative agent of a lethal disease affecting several tortoise species. The threat that this virus poses to endangered animals is focusing efforts on characterizing its properties, in order to enable the development of prophylactic methods. We have sequenced the genomes of the two most studied TeHV-3 strains (1976 and 4295).

Improving adjuvant systems for polyclonal egg yolk antibody (IgY) production in laying hens in terms of productivity and animal welfare.

The antibody production in the egg yolks of immunized laying hens is seen as a way of improving animal welfare compared with conventional production by mammals. Immunoglobulin Y (IgY) technology, however, has still to address welfare issues linked to the widespread use of an adjuvant in vaccines. Currently, Freund's adjuvants, complete (FCA) or incomplete (FIA), remain the standard.

Detection of Usutu virus in a bullfinch (Pyrrhula pyrrhula) and a great spotted woodpecker (Dendrocopos major) in north-west Europe.

In October 2012, a 3-year-old bullfinch (Pyrrhula pyrrhula) held in captivity for its entire lifespan and a wild adult great spotted woodpecker (Dendrocopos major), both with neurological signs, were found 4 km from each other and 5 days apart in the Meuse Valley, Belgium. Non-suppurative encephalitis and mild degeneration and necrosis were identified in the brain and cerebellum, and Usutu virus antigen and RNA were detected by immunohistochemistry and real-time reverse transcriptase PCR, respectively. The two cases reported here represent the most western distribution of clinical disease in birds due to Usutu virus in Europe.

Epizootic rabbit enteropathy inoculum (TEC4): antibiograms and antibiotic fractionation.

Epizootic rabbit enteropathy (ERE) emerged and spread in Europe within the last 13 years causing major economical loss. The aims of the study was to evaluate antibiograms of TEC4, an inoculum composed of an extract of intestinal content of affected rabbits, and to test the potential of different antibiotic-based TEC4 fractions to reproduce the disease. Twenty nine different antibiotic discs were incubated for determining bacteria resistance.
