Subcutaneous clostridial infection in broilers   总被引：2，自引：0，他引：2  

C L Hofacre  J D French  R K Page  O J Fletcher 《Avian diseases》1986,30(3):620-622

A flock of 12,500 broilers 36 days of age experienced a sudden increase in mortality. Post-mortem lesions were emphysema, severe enteritis, and a serosanguineous fluid in the subcutaneous tissue of the breast and thighs; there was no evidence of a loss in the integrity of the skin. Clostridium perfringens and C. septicum were isolated from the affected subcutaneous tissue. Histopathological and serological examination indicated previous infection with infectious bursal disease virus. The subsequent immunosuppression and severe enteritis may have permitted the clostridia access to the circulatory system, with localization in the subcutaneous areas of the breast and thighs. Mortality returned to normal 48 hours after potassium penicillin G was administered via the drinking water.  相似文献

Pathologic sideroblasts and siderocytes associated with chloramphenicol therapy in a dog     

Harvey JW  Wolfsheimer KJ  Simpson CF  French TW 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1985,14(1):36-42

Siderotic granules were recognized in blood erythrocytes from a male Boxer dog with suppurative prostatitis, cystitis and pyelonephritis that was being given high dosage chloramphenicol therapy. Siderotic inclusions were recognized in the cytoplasm of 96% of the rubricytes and metarubricytes in a bone marrow aspirate. Siderotic inclusions were numerous and in some cases formed a ring around the nucleus. This perinuclear location suggested that pathologic mitochondrial iron accumulation had occurred, resulting in the formation of "ringed" sideroblasts. The occurrence of pathologic sideroblasts was confirmed by electron microscopy. Blood siderocytes and bone marrow sideroblasts disappeared after cessation of chloramphenicol therapy.  相似文献   

Treatment of equine leg wounds using skin grafts: Thirty-five cases, 1975-1988          下载免费PDF全文

French DA  Fretz PB 《The Canadian veterinary journal. La revue veterinaire canadienne》1990,31(11):761-765

A retrospective study was conducted on 35 equine patients with lower leg wounds that were managed utilizing skin graft procedures. Two pinch graft, five punch graft, seven tunnel graft, eight split-thickness mesh graft and thirteen full-thickness mesh expansion graft procedures were performed in the initial treatment. The average wound size was 188 cm². Twentyfour cases had pregrafting complications: 10 wounds developed sequestra; three wounds were grossly contaminated and infected; and 11 cases developed granulation tissue complications prior to grafting. Graft failure following the initial procedure was seen in 12 cases and occurred with all techniques except pinch grafting. Graft failure was often attributable to poor quality of granulation tissue as well as anatomic site, especially the dorsal surface of the tarsus. An average of two additional grafting procedures was required to successfully treat initial failures. Pinch grafts took the longest time to epithelialize (70 days), followed by punch grafts (47 days). Both were similar in terms of being the least durable and least cosmetically acceptable of all techniques used. Split-thickness and full-thickness mesh expansion grafts were technically the most difficult, but showed the most rapid epithelialization (28 days), greatest durability, and the best cosmetic appearance. Tunnel grafts provided a practical technique for grafting cases which were either not suited for, or which had failed with, mesh expansion grafts.  相似文献

Network analysis of wildlife translocations in New Zealand     

M Van Andel  K McInnes  T Tana  NP French 《New Zealand veterinary journal》2016,64(3):169-173

AIMS: To identify network measures with relevance to disease spread in a network of movements derived from the Department of Conservation (DOC) translocation records from 1970 to mid-2014, and to identify conservation sites that should be prioritised for surveillance activities and improvements to data collection to make the best use of network analysis techniques in the future.

METHODS: Data included the source and destination of translocated specimens, the species and the dates the translocations were expected to occur. The data were used to construct a directed, non-weighted network in which a translocation event represented a tie in the network. Network density, in-degree (movements entering a node of interest) and out-degree (movements leaving a node of interest) and reciprocity were calculated.

RESULTS: The data analysed consisted of 692 unique translocations between 307 sites, with the majority (518; 73%) being for birds. The constructed network for bird, reptile and frog translocations comprised 260 nodes, with 34/260 (13%) having two-way movements and 47/260 (18%) non-reciprocal movements. The median degree score (sum of in- and out-degree) was two (min 0, max 36) with a mean of 3.5 in a right skewed distribution. Most sites acted as receivers or senders of consignments with only a few having both high in- and high out-degree, and thus had characteristics that made them sites of interest for surveillance activities. These included the National Wildlife Centre at Mount Bruce, Tiritiri Matangi Island and Te Kakahu (Chalky Island).

CONCLUSIONS: The presence of linking sites that join larger clusters within the network creates the potential for rapid disease spread if a pathogen were to be introduced. The important sites that supply or receive specimens for translocations are already well recognised by those performing translocations in New Zealand, and this paper provides further information by quantifying their role within the network.  相似文献   

Non-disease problems influencing livestock production in developing regions     

M. H. French 《Tropical animal health and production》1970,2(1):1-12

Resumen Por falta de calorías y proteínas más de 300 millones de ni?os sufren de crecimiento y desarrollo retardado, al mismo tiempo que el desarrollo mental, la habilidad de aprender y comportamiento general de muchos puede da?arse. Desgraciadamente la producción mundial de alimentos no marcha al mismo paso que el aumento de población no obstante los ensayos actuales para aparejarlos. Además, esfuerzos en gran escala son necesarios para aumentar la calidad y cantidad de alimentos convencionales de fuentes agrícolas, pesqueras y pecuarias; se está haciendo algo también para producir alimentos proteínicos de tipo no convencional de fuentes vegetales, levadura, hongos, microorganismos y materiales sintéticos. Este artículo trata solamente con los aumentos de producción de proteínas animales tradicionales tales como carne, leche, huevos y sus derivados ya que tales alimentos son bien recibidos por un gran porcentaje de la problación mundial y van a seguir en demanda después de que se hayan desarrollado los nuevos substitutos.

Résumé A cause de l'insuffisance des rations en calories et en protéines, plus de 300 millions d'enfants souffrent de retard dans leur croissance et leur développement physique, tandis qu'un très grand nombre d'entre eux voit leur développement mental, leur capacité à apprendre et leur comportement général très altérés. Malheureusement la production alimentaire mondiale ne marche pas du même pas que l'accroissement des populations en dépit des efforts faits pour essayer de combler ce déficit. Par ailleurs, des essais à très grande échelle sont nécessaires pour augmenter la quantité et la qualité des aliments conventionnels issus de l'agriculture, des pêches et des productions animales; on essaie aussi de produire des protéines alimentaires non conventionnelles à partir de sources végétales, de levures, de champignons, de microorganismes et même de matériaux synthétiques. Cet article traite seulement des accroissements de rendement des protéines animales traditionnelles issues des viandes, du lait, des oeufs et de leurs sousproduits, étant donné que de tels aliments sont aisément acceptés par un haut pourcentage de la population mondiale et que leur demande continuera après que les aliments nouveaux auront été élaborés.

Phenylbutazone induces equine glandular gastric disease without decreasing prostaglandin E2 concentrations          下载免费PDF全文

S. K. Pedersen  A. E. Cribb  E. K. Read  D. French  H. E. Banse 《Journal of veterinary pharmacology and therapeutics》2018,41(2):239-245

In equids, phenylbutazone at high doses induces gastric disease, primarily in the glandular portion of the stomach. However, the mechanism of nonsteroidal anti‐inflammatory drug (NSAID)‐induced gastric disease in horses has yet to be determined. While phenylbutazone‐associated ulceration is often attributed to a decrease in basal gastric prostaglandins, this has not been demonstrated in the horse. Twelve horses were randomly assigned to treatment (n  = 6; 4.4 mg/kg phenylbutazone PO in 20 ml molasses q 12 hr for 7 days) or placebo (n  = 6; 20 ml molasses PO q 12 hr for 7 days) groups. Before treatment and 3 and 7 days after initiation of treatment, gastroscopy was performed and glandular gastric biopsies were collected and frozen at ?80°C. Glandular disease was assessed on a scale of 0–4. Prostaglandin E₂ concentrations in biopsies were measured using a commercially available enzyme‐linked immunosorbent assay. All phenylbutazone‐treated horses developed grade ≥2 glandular disease. Prostaglandin concentrations increased over time (p  = .0017), but there was no effect of treatment (p  = .49). These findings indicate that despite induction of glandular disease grade ≥2, phenylbutazone did not decrease basal glandular gastric prostaglandin E₂ concentration.  相似文献
