Discovery of a new avian bornavirus genotype in estrildid finches (Estrildidae) in Germany     

Dennis Rubbenstroth  Volker Schmidt  Monika Rinder  Marko Legler  Victor Max Corman  Peter Staeheli 《Veterinary microbiology》2014,168(2-4):318-323

Avian bornaviruses (ABV) are known to be the causative agent of proventricular dilatation disease (PDD) in parrots and their relatives (Psittaciformes). A broad range of ABV genotypes has been detected not only in psittacine birds, but also in other avian species including canary birds (Serinus canaria forma domestica) and Bengalese finches (Lonchura striata f. dom.), which are both members of the order songbirds (Passeriformes).During this study 286 samples collected from captive and wild birds of various passerine species in different parts of Germany were screened for the presence of ABV. Interestingly, only three ABV-positive samples were identified by RT-PCR. They originated from one yellow-winged pytilia (Pytilia hypogrammica) and two black-rumped waxbills (Estrilda troglodytes) from a flock of captive estrildid finches in Saxony. The ABV isolates detected here were only distantly related to ABV isolates found in passerine species in Germany and Japan and form a new genotype tentatively called ABV-EF (for “estrildid finches”).  相似文献   

Comparative Analysis of mRNA Expression of Surface Antigens between Histiocytic and Nonhistiocytic Sarcoma in Dogs     

H. Yamazaki  S. Takagi  N. Oh  Y. Hoshino  K. Hosoya  M. Okumura 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》2014,28(1):204-210

Background

Definitive diagnosis of histiocytic sarcoma (HS) in dogs is relatively difficult by conventional histopathological examination because objective features of HS are not well defined.

Hypothesis

Quantitative analysis of mRNA expression of selected cellular surface antigens (SAs) specific to HS in dogs can facilitate objective and rapid diagnosis.

Animals

Dogs with HS (n = 30) and dogs without HS (n = 36), including those with other forms of lymphoma (n = 4), inflammatory diseases (n = 6), and other malignant neoplasias (n = 26).

Methods

Retrospective clinical observational study. Specimens were collected by excisional biopsy, needle core biopsy, or fine needle aspiration. To determine HS detection efficacy, mRNA expression levels of selected SAs specific to HS in dogs, including MHC class IIα, CD11b, CD11c, and CD86, were quantitatively analyzed using real‐time quantitative polymerase chain reaction.

Results

Each SA mRNA expression level was significantly higher in HS dogs than in non‐HS dogs (P = .0082). Cutoff values for discriminating between HS and non‐HS dogs based on these expression levels were calculated on the basis of receiver‐operating characteristic analysis. Accuracy of the cutoff values, including MHC class IIα, CD11b, CD11c, and CD86, was 87.9, 86.4, 86.4, and 84.8%, respectively.

Conclusions and Clinical Importance

Our results suggest that quantitative analysis of mRNA expression of the selected SAs could be an adjunctive diagnostic technique with high diagnostic accuracy for HS in dogs. Substantial investigation is required for exclusion of diseases with similar cell types of origin to lymphoma.  相似文献   

肝片吸虫感染致斑纹角马死亡案例调查

首次报道了国内圈养斑纹角马肝片吸虫病确诊病例。诊断依据：（1）提示性临床症状：贫、消瘦、营养不良;（2）尸体剖检特征性病理变化：胆管显著扩张和胆管内挤排出大量肝片吸虫成虫的虫体;（3）肝片吸虫感染强度测定：运用麦克马斯特法测定了病死角马肝片吸虫感染强度为1 600个/g;（4）中间宿主调查：角马的饲养区内发现大量椎实螺,椎实螺体内含有大量的肝片吸虫尾蚴;（5）组织病理学检查：细支气管和肺泡腔内见有童虫的虫体结构。首次证实了角马肝片吸虫感染时,童虫在移行过程中可误移至肺,导致肺的病理变化。该病的发生与环境潮湿多水、环境中存在大量椎实螺而未被重视有关。肝片吸虫宿主范围广,应重视易感动物的生活环境,定期粪检确定感染率和感染强度,以及选择有效的药物防治,这是科学预防该病的关键。  相似文献
