Genetic sequencing using 16S rRNA for pathogen identifi cation in retropharyngeal lymph nodes from wild elk
نویسنده
چکیده
Cervical region lymph nodes collected by hunters from 43 wild hunter-harvested elk (Cervus elaphus) in Utah were submitted to the Utah Veterinary Diagnostic Laboratory during fall 2009. We evaluated these lymph nodes as specimens for identifi cation of bacterial pathogens using 16S rRNA genetic sequencing. Thirty-seven bacterial species were identifi ed; each was found in 2 to 30 individual elk. Many common ruminant livestock pathogens were identifi ed in elk; pathogens previously reported in elk were Pasteurella multocida and Streptococcus spp. Cervical region lymph nodes harvested from wild ruminants appear to be acceptable samples for genetic sequencing of bacteria.

Nodeomics: Pathogen Detection in Vertebrate Lymph Nodes Using Meta-Transcriptomics
The ongoing emergence of human infections originating from wildlife highlights the need for better knowledge of the microbial community in wildlife species where traditional diagnostic approaches are limited. Here we evaluate the microbial biota in healthy mule deer (Odocoileus hemionus) by analyses of lymph node meta-transcriptomes. cDNA libraries from five individuals and two pools of samples...
متن کاملGenetic Characterization of Argas persicus From Iran by Sequencing of Mitochondrial Cytochrome Oxidase I (COX1) and 16s rRNA Genes
Background: Argas persicus has a great importance for health and veterinary, it can transmit many infectious agents such as Borrelia anserina (avian spirochetosis) and Aegyptianella pullorum. Distinguishing Argasidae due to close morphological relationship is difficult. OBJECTIVES: In the present study, we performed molecular analyses based on PCR and sequencing of Amplicon derived from 16S rRN...
متن کاملLevels of Abnormal Prion Protein in Deer and Elk with Chronic Wasting Disease
Chronic wasting disease (CWD) of deer and elk is a widespread health concern because its potential for crossspecies transmission is undetermined. CWD prevalence in wild elk is much lower than its prevalence in wild deer, and whether CWD-infected deer and elk differ in ability to infect other species is unknown. Because lymphoid tissues are important in the pathogenesis of some transmissible spo...
متن کاملEfficacy of antemortem rectal biopsies to diagnose and estimate prevalence of chronic wasting disease in free-ranging cow elk (Cervus elaphus nelsoni).
A reliable antemortem test is needed to understand the ecology of chronic wasting disease (CWD) in elk (Cervus elaphus nelsoni). We measured the ability of antemortem biopsy samples from the rectal mucosa to detect the abnormal prion protein associated with CWD (PrP(CWD)), the relationship between test results from the obex and rectal biopsies at varying stages of CWD progression, and the preva...

Preclinical diagnostic tests for transmissible spongiform encephalopathies have been described for mule deer (Odocoileus hemionus), using biopsy tissues of palatine tonsil, and for sheep, using lymphoid tissues from palatine tonsil, third eyelid, and rectal mucosa. The utility of examining the rectal mucosal lymphoid tissues to detect chronic wasting disease (CWD) was investigated in Rocky Moun...
