Humoral Antibody Response to Experimental Sarcoptes scabiei var. vulpes Infection in the Dog
Authors: BORNSTEIN SET , ZAKRISSON GORAN 
Published: March 2008

Abstract— Humoral antibody responses to experimental Sarcoptes scabiei var. vulpes infection in 10 beagle dogs were demonstrated by an ELISA in three experiments. In the first experiment, four dogs, infected with a relatively high dose of S. scabiei, seroconverted 2 weeks post infection. All four animals showed clinical signs of sarcoptic mange. In the second experiment, six dogs were infected with a relatively low dose of S. scabiei. Three of the dogs developed clinical signs of sarcoptic mange and only in these three were antibodies to S. scabiei demonstrated. Seroconversion occurred 4–5 weeks post infection. The six dogs infected with a low dose of Sarcoptes were re‐infected with a relatively low dose of mites 7 weeks after the spontaneous clinical recovery of the three dogs that had exhibited mange following the primary infection. The later three dogs showed a specific antibody response within 1 week and the other three dogs within 2 weeks following the re‐infection.Resumen  En tres experimentos se demostraron las respuestas humorales de anticuerpos a la infección con Sarcoptes scabiei var. vulpes en 10 perros de la raza Beagle por medio de pruebas ELISA. En el primer experimento cuatro de los perros infectados con una dosis relativamente alta de Sarcoptes, seroconvirtieron 2 semanas despues de la infección. Estos cuatro animales mostraban cuadro clínico de infección. En un segundo experimento seis de los perros se sometieron a una dosis relativamente baja del ácaro. Solo tres de estos perros demostraron cuadro clínico de la infección, y en éstos animales exclusivamente se encontraron anticuerpos de S. scabiei. Cinco o seis semanas después de la infección se produjo la seroconversión de los mismos. Los seis perros infectados con una dosis baja se volvieron a re‐infectar con otra dosis relativamente baja siete semanas después de la recuperatión clínica espontánea de los tres perros que habían padecido el cuadro clínico de la sarna, después de la infección previa. Los últimos tres perros produjeron una respuesta de anticuerpos específica en una semana, y los otros tres perros en dos semanas después de la infección.
Double‐blind Comparison of Three Concentrated Essential Fatty Acid Supplements in the Management of Canine Atopy
Authors: BOND ROSS , LLOYD DAVID H. 
Published: March 2008

Abstract— A randomised double‐blind parallel study lasting 16 weeks compared the efficacy of a concentrated essential fatty acid supplement containing 280 mg of GLA and 50 mg of EPA (HGF 500 mg capsules, Efamol Vet) with supplements containing 350 mg of GLA (HGG capsules), and 250 mg of EPA (HGE capsules). Twenty‐eight atopic dogs whose clinical signs were well‐controlled by HGF either continued to receive HGF or were switched to HGG or HGE. The dogs were clinically examined by the same veterinary surgeon at 4‐week intervals and assessments of pruritus, scaling, erythema, infiltration, coat condition and overall severity recorded. Clinical scores for each criterion assessed and plasma phospholipid concentrations for four fatty acids measured did not vary significantly (P > 0.05) during the study period, indicating that the three supplements assessed were of comparable therapeutic efficacy in the atopic dogs studied.Resumen  Un estudio paralelo al azar de tipo doble ciego que duró diecieséis semanas, comparó la eficacia de un suplemento concentrado de ácidos grasos esenciales conteniendo 280 mg de GLA y 50 mg de EPA (HGE 500 mg cápsulas, Efamol Vet) con suplementos que contenían 350 mg de GLA (HGG cápsulas), y 250 mg de EPA (HGG cápsulas). Veintiocho de los perros atópicos en los que el cuadro clínico estaba bajo control con HGF continuaron recibiendo el mismo suplemento, o se les cambió a la medicación con HGG o HGE. Los perros fueron examinados por el mismo veterinario periódicamente cada 4 semanas, evaluándose el prurito, descamación, eritema, infiltración, condición del pelo, y severidad de la enfermedad cutánea. La evaluación clínica para cada criterio evaluado, y las concentraciones de fosfolipídos de los cuatro ácidos grasos medidos, no varió significativamente (P > 0.05) durante el periodo de estudio, indicando que la eficacia de los 3 suplementos comparados fue similar para los perros atópicos de éste estudio.Résumé— Une étude en double aveugle de seize semaines a été réalisée pour comparer une préparation en acides gras essentiels contenant 280 mg de GLA et 50 mg d'EPA (capsules HGF 500 mg, Efamol Vet), un supplément contenant 350 mg de GLA (capsules HGG) et un contenant 250 mg d'EPA (capsules HGE). Vingt huit chiens atopiques dont les symptômes étaient controlés par l'HGF ont soit continuéá recevoir de l'HGF soit de l'HGE, soit de l'HGG. Les animaux ont été examinés par le même vétérinaire toutes les quatre semaines et l'évolution du prurit, du squamosis, de l'érythème, de l'infiltration, de l'état du pelage et de la sévérité générale a été enregistrée. Les scores cliniques de chaque critère et les concentrations plasmatiques de quatre acides gras n'ont pas varié de facon significative (P > 0,05) pendant la durée de l'étude, indiquant que ces trois suppléments avaient une efficacité comparable chez les chiens atopiques étudiés.

In this report, we describe a case of severe generalized apocrine cystomatosis in an Old English Sheepdog. Although the condition is usually regarded as a non‐neoplastic process, the behaviour and histology of the lesions in our case are compatible with a benign tumor. Furthermore, we detected the expression of the receptor for epidermal growth factor, a potent mitogen for glandular epithelia, in secretory cells lining apocrine cysts.

Résumé— La dermatose lupoïde du Braque Allemand doit être considéré comme une génodermatose bien que le nombre de cas décrit soit faible. Cette maladie concerne de jeunes chiens. Aucune prédisposition sexuelle n'est notée. Pour l'instant, cette maladie n'a été observée que chez le Pointer. Le diagnostic repose sur l'examen clinique et l'examen histopathologique des biopsies cutanées. Le pronostic est généralement réservé, mais l'utilisation des acides gras et un traitement symptomatique peuvent être préconisés. [Vroom, M.W., Theaker, M.J., Rest, J.R., White, S.D.

Abstract  Impetigo and fürunculosis appeared in a dairy cattle herd in association with intensive showering of the lactating cows during the summer months. Heifers and dry cows in the same herd, as well as those in a neighbouring herd in the same village, which was not showered and served as a comparison herd, remained unaffected.Skin lésions declined with the termination of showering. Only six animals [three cows (7.3%) and three first‐calving cows (20%)] had to be treated parenterally with antibiotics.Resumen  En un rebafio de vacas de leche aparecieron cuadros de impetigo y fürunculosis asociados a las duchas frecuentes aplicadas durante los meses de verano a las vacas lactantes.

Published: March 2008

Abstract: Purpose:  Post‐Transplant Lymphoproliferative Disorder (PTLD) is a life threatening complication in organ transplant recipients. Risk factors include primary Epstein‐Barr virus infection, intensity of immunosupression and cytomegalovirus infection.Objectives:  To evaluate the incidence, clinical presentation, risk factors, histopathologic appearance and outcome of pediatric liver recipients with PTLD at our institution.Method:  Retrospective, descriptive and observational analysis. Between November 1992 and December 2005, 383 liver transplants were performed. The diagnosis of PTLD was based on clinical history and physical examination and confirmed by histologic appearance and immunohistologic staining. Knowles’ classification was used for histopathologic diagnosis.Results:  The incidence of PTLD was 5.7% (n: 22p). The average onset after tansplantation (OLT) was 24.9 months. Clinical manifestations were malaise, anorexia, fever of more than 3 days, peripheral adenopathy, tonsillar hypertrophy, abdominal mass, hepatosplenomegaly, snoring, interstitial pulmonary infiltrate, G.T.‐tract bleeding, rash, submaxilar mass. Histopathologic diagnosis were Plasmocytic Hyperplasia (n: 10), Polymorphic Lymphoproliferative Disorder (n: 8), Non‐Hodgkin Lymphoma (n: 4). Mortality was 18%.Conclusion:  The clinical presentations were protean and not specific. A high index of suspicion is important for early diagnosis as it correlates with more benign lesions and more favorable outcume. The lower mortality rate in our series is concordant with that reported in more recent articles.
Do Conversational Gutturals Help Florida Scrub‐Jays Coordinate Their Sentinel Behavior?
Authors: Bednekoff Peter A. , Bowman Reed , Woolfenden Glen E. 
Published: March 2008

AbstractFlorida scrub‐jays, Aphelocoma coerulescens, perform sentinel behavior in which individuals alternate bouts of watchfulness with little overlap. We examined how calls might facilitate sentinel coordination. Small soft calls labeled conversational gutturals were heard more often from sentinels than from foraging birds. Calls occurred infrequently throughout sentinel bouts but were more common later in bouts. The pattern of calling does not match predictions for a ‘watchman’s song’ at regular intervals nor for a signal at the end of a sentinel bout. Thus, our quantitative assessment of calling by sentinels did not find support for either standard hypothesis. Although Florida scrub‐jays clearly have information on each other’s sentinel behavior, our results suggest that calls provide perhaps a fraction of this information.
Carotenoid‐Based Plumage Coloration Predicts Leukocyte Parameters during the Breeding Season in Northern Cardinals (Cardinalis cardinalis)
Authors: Maney Donna L. , Davis Andrew K. , Goode Christopher T. , Reid Allison , Showalter Christopher 
Published: March 2008

AbstractDichromatism in songbirds is often associated with polygyny and dimorphic parental investment, and is thought to arise via sexual selection. Northern cardinals (Cardinalis cardinalis) are not only dichromatic but also monogamous and biparental, suggesting that plumage coloration in this species may serve different functions than in more typical dichromatic species. In order to explore the role of sexual selection in the evolution of plumage coloration in cardinals, we used reflectance spectrophotometry to investigate whether two carotenoid‐based ornaments, the male’s red breast and the female’s underwing coverts, contain information that potential mates or competitors could use to assess condition. We found that whereas coloration was not related to body condition (measured as the residual body mass from a regression of body mass on wing chord), more saturated carotenoid coloration was associated with higher heterophil to lymphocyte ratios in males, and with higher white blood cell counts in females. Thus, in both sexes, carotenoid coloration was positively linked to immune measures normally associated with higher levels of stress and infection. These results do not indicate that carotenoid‐based coloration functions as a signal of low levels of stress or disease in this species. We propose instead that because plumage coloration may be related to competitiveness, the more saturated individuals increase their risk of injury, stress, and infection by engaging in more competitive behavior or by secreting more testosterone, or both. Our finding that carotenoid pigmentation is positively associated in males with the size of the cloacal protuberance, an androgen‐sensitive sex character, supports this hypothesis.
Seasonal Changes of Vocal Rates and Their Relation to Territorial Status in Male Galápagos Sea Lions (Zalophus wollebaeki)
Authors: Kunc Hansjoerg P. , Wolf Jochen B. W. 
Published: March 2008

AbstractMale vocal displays play an important role in sexual selection through both male–male competition and female choice. While this is supported by numerous studies in birds, much less attention has been paid to the role of such displays in mammals. We investigated the function of vocal displays in a polygynous mammal, the Galápagos sea lion (Zalophus wollebaeki). In our study population a large proportion of mature males are unable to establish a territory, providing the opportunity to compare the vocal behaviour between territorial and non‐territorial males. We examined how seasonal patterns of vocalizations differed between territorial and non‐territorial males and how the number of females present in a territory influenced behaviour of territorial males. We found that territorial males vocalized at higher rates than non‐territorial males, and territorial males vocalized more at the onset than towards the end of territory tenure. During the onset of territory‐tenure vocalizations of territorial males were directed more often towards other males than females. Furthermore, we found that vocalizations of territorial males were not only given in male–male interactions, but were also actively directed towards females. Territorial males vocalized at higher rates when more females were present in their territory. Our results suggest that vocalizations are important in male–male interactions, are relevant in territorial disputes and are used as a proxy for females to assess a male’s quality.
