“…As in humans afflicted with MD, the microscopic filaments seen in the canine cases were predominantly white, blue and red. However, in Citation: Middelveen MJ, Rotaru GM, McMurray JL, Filush KR, Sapi E, et al (2016) cases C-3 and C-4, in addition to blue and white microscopic filaments, thickened coarse black fibers were also present, and microscopic examination revealed scaling and follicular bulbs consistent with hair structures, thus indicating keratin composition. Dermatological specimens from dogs C-3 and C-4 also displayed deformed follicles.…”

“…in human Morgellons samples. Thus co-infecting pathogens or other spirochetes could be involved in Citation: Middelveen MJ, Rotaru GM, McMurray JL, Filush KR, Sapi E, et al (2016) MD-type filamentous dermatological manifestations. We speculate that tickborne co-infections and co-involved infections such as H. pylori and T. denticola could be contributing secondary factors in the development of filamentous borrelial dermatitis.…”

No Citation: Middelveen MJ, Rotaru GM, McMurray JL, Filush KR, Sapi E, et al (2016) laboratory method for detecting pathogens in bodily fluids and tissues is 100% sensitive and specific. Therefore, we relied on different methodologies that collectively provided corroborative evidence of Borrelia infection in this cohort of dogs.…”

Background: Although canine clinical manifestations of Lyme disease vary widely, cutaneous manifestations are not well documented in dogs. In contrast, a variety of cutaneous manifestations are reported in human Lyme disease caused by the spirochete Borrelia burgdorferi. A recently recognized dermopathy associated with tickborne illness known as Morgellons disease is characterized by brightly-colored filamentous inclusions and projections detected in ulcerative lesions and under unbroken skin. Recent studies have demonstrated that the dermal filaments are collagen and keratin biofibers produced by epithelial cells in response to spirochetal infection. We now describe a similar filamentous dermatitis in canine Lyme disease. Methods and Results: Nine dogs were found to have cutaneous ulcerative lesions containing embedded or projecting dermal filaments. Spirochetes characterized as Borrelia spp. were detected in skin tissue by culture, histology, immunohistochemistry, polymerase chain reaction (PCR) and gene sequencing performed at five independent laboratories. Borrelia DNA was detected either directly from skin specimens or from cultures inoculated with skin specimens taken from the nine canine study subjects. Amplicon sequences from two canine samples matched gene sequences for Borrelia burgdorferi sensu stricto. PCR amplification failed to detect spirochetes in dermatological specimens from four healthy asymptomatic dogs. Conclusions:Our study provides evidence that a filamentous dermatitis analogous to Morgellons disease may be a manifestation of Lyme disease in domestic dogs.

Las afecciones por NGI son consideradas como causa importante de pérdida en la productividad ovina, reducción de los niveles de producción y productividad, alteraciones reproductivas y altos costos de control, además de la mortalidad que pueden ocasionar (Charlier et al, 2014;Eisa et al, 2017;Grisi et al, 2014;Kenyon et al, 2017;Rodríguez-Vivas et al, 2017;Vercruysse et al, 2018).…”

La desparasitación selectiva dirigida (DSD) permite reducir la frecuencia de animales tratados con antihelmínticos (AH) en rebaños de ovinos. Se desconoce si la DSD pudiera funcionar en ovejas de raza Dorper, que es una raza muy susceptible a nemátodos gastrointestinales (NGI). Este estudio evaluó la estrategia de DSD en una granja de ovinos Dorper en la zona centro de Tamaulipas, México. Primero, se determinó cuál AH podía ser usado en la DSD. Se realizó el diagnóstico de resistencia con las tres clases de AH de amplio espectro (levamisol, fenbendazol, ivermectina) y la combinación de levamisol y febendazol, mediante la prueba de reducción de huevos en heces. Posteriormente, se estableció el esquema DSD mensual durante 6 meses, en una población de entre 74 y 98 ovejas adultas. A cada oveja se le determinó una vez al mes la FAMACHA©, condición corporal (CC) y se obtuvo una muestra de heces de los animales flacos (CC ≤ 2) o con mucosa pálida (FAMACHA© > 3). Las heces fueron procesadas mediante la técnica de McMaster y los animales con ≥ 750 huevos de NGI en heces fueron desparasitados. La granja tuvo una población de NGI multi-resistentes contra las tres clases de AH, pero la combinación levamisol-fenbendazol mostró 100 % de eficacia, por lo que se usó en el estudio. El uso de la DSD redujo el uso de AH, pasando de 100% de las ovejas tratadas en el semestre, a solo entre 33.63% y 1.35% de los animales en cada mes. El uso del umbral ≥ 750 huevo por gramo de heces (HPG) permitió mantener casi 75% de los animales flacos o de mucosa pálida sin ser desparasitados. En conclusión, la DSD puede disminuir el uso de AH en un rebaño de ovejas Dorper de la zona centro de Tamaulipas, México.
