Title: 
De Maréchal-Vétérinaire in de Grande Armée van Napoleon (1805-1815)
Author(s): 
P.E.J. BOLS, E. DUMAS, J. OP DE BEECK, H.F.M. DE PORTE
Abstract: 
Op 18 juli 2015 was het precies tweehonderd jaar geleden dat Napoleon met zijn GrandeArmée werd verslagen door de geallieerde strijdkrachten in wat de geschiedenis zou ingaanals de Slag bij Waterloo. Tijdens de tien jaar die aan deze nederlaag voorafgingen, bouwde deFranse keizer een gigantische troepenmacht uit waarin de bereden component of cavalerie eenzeer belangrijke rol speelde. Omdat de paarden die hierin figureerden eerder al het onderwerpwaren van een publicatie in dit tijdschrift, richt dit artikel specifiek de aandacht op de militaireveeartsen die als paardenarts instonden voor de verzorging van de honderdduizenden legerpaardendie tijdens het verloop van het keizerrijk onder de wapens werden gebracht. Na eenkorte inleiding over het ontstaan van het veeartsenijkundig onderricht, wat hand in hand gingmet de geboorte van de militaire veearts, wordt dieper ingegaan op zijn rekrutering, statuut enwerkomgeving. Hierbij wordt de rol van de keizer zelf beschreven met een bespreking van hetdecreet van Moskou dat voor het veeartsenijkundig onderwijs van zeer groot belang is geweest.Tenslotte worden de werkomstandigheden van de militaire veeartsen belicht aan de hand vanenkele ooggetuigenverslagen.

Abstract: 
A presumably female intact French bulldog of ten months old was presented to the Faculty of VeterinaryMedicine of the Ghent University with an enlarged clitoris and purulent vaginal discharge. It wassuggested to remove the enlarged clitoris as to avoid further irritation and to perform a gonadectomyat the same time, since the owners were not planning to breed with the dog. An abnormal reproductivetract was observed during surgery. A normal uterus was present, but both gonads resembled testes.Histologic examination of the resected tissues confirmed the presence of bilateral testes in combinationwith a normal uterus. Karyotyping and molecular analysis of the SRY-gene resulted in a 78,XX SRYnegativekaryotype. The French bulldog was diagnosed with a 78,XX SRY-negative testicular disorderof sex development (DSD).

Title: 
Multiple dermoid sinus cysts on the head of a miniature schnauzer
Author(s): 
D. BUIJTELS, B. VAN GOETHEM, H. DE COCK, H. DE ROOSTER, S. VANDENABEELE
Abstract: 
A one-year-and-nine-months-old, neutered, female Miniature schnauzer was presented to the primarycare veterinarian with a skin lesion between the eyebrows. There were multiple papulae presentat birth, and later, small fistulae with protruding hair bundles appeared. Topical antibiotic therapy andepilation of the hairs only brought temporary relief and a presumptive diagnosis of dermoid sinus cystswas made. The dog was referred and the skin lesions were surgically excised. During histopathologicalexamination, the lesion was diagnosed as multiple dermoid sinus cysts, a consequence of the incompleteseparation of the ectoderm during embryogenesis. Depending on the depth of the tubular dermalinvaginations and the location of the lesions, different types have been recognized. This is the third dogdescribed in the literature with dermoid sinus cysts on the head.

Title: 
Evaluation of two intensive treatment schedules against Psoroptes ovis mange in Belgian blue cattle on nine Flemish farms

Abstract: 
Psoroptic mange, caused by Psoroptes ovis, is a problem on many Flemish farms where Belgianblue beef cattle are bred. Two intensive treatment schedules were evaluated on nine Belgian blue farmswith a persistent mange problem. On farms 1 to 7, all animals were treated twice (with a seven-to-tendaysinterval) with an injectable macrocyclic lactone (ML), while on the two remaining farms, theinitial treatment consisted of one injection with the long acting (LA) formulation of moxidectin (10%).Skin scrapings were taken after treatment, and when living mites were found on at least one animal,all animals (farms 1 to 7) or only positive animals (farms 8 and 9) were treated consecutively with aninjectable ML. On all farms, the treated animals were clinically healthy and P. ovis free at the end ofwinter, after two to nine treatment rounds (two injections with a seven to ten-days interval or one LAinjection). Although mange reappeared on the first seven farms after the subsequent grazing season, thedisease was less severe and easier to control.

Title: 
Pathogenesis of Actinobacillus pleuropneumoniae infections in pigs and its relevance to vaccine development
Author(s): 
G. VAN DEN WYNGAERT, E. DE BRUYNE, F. BOYEN, F. PASMANS, F. HAESEBROUCK
Abstract: 
Contagious porcine pleuropneumoniae is caused by Actinobacillus pleuropneumoniae. The agent isable to adhere to the epithelium of the lower respiratory tract and lung alveoli. Type IV fimbriae play,amongst other virulence factors, an important role in the adhesion phase. Transferrin binding proteinsmediate the uptake of iron by this bacterium, which is necessary for its multiplication. The typicalhemorrhagic to necrotizing lesions in the lungs are primarily caused by the production of Apx toxins.By forming biofilms and producing proteases, Apx toxins and ammonia, A. pleuropneumoniae is ableto circumvent the immune system of the host. Antibodies directed against the lipoprotein PalA mayaggravate the course of infection, and counteract the protective effect of antibodies targeting the Apxtoxins. In-depth knowledge on host-pathogen interactions may lead to the development of efficientvaccines. The protection observed after vaccination with bacterins, such as autologous vaccines, isserotype-specific and variable. This may be attributed to variable levels of PalA in these vaccines. Untilnow, the best results have been obtained using an experimental vaccine containing type IV fimbriae,transferrin binding proteins and Apx toxins.
