| Abstract |
An autopsy case of infectious aortic aneurysm in a 62-year-old diabetic male patient was reported. The causative pathogen isolated from blood culture was identified as Salmonella enterica serovar, Enteritidis. To confirm a patho-etiologic relationship we attempted a PCR-based detection of nontyphoid Salmonella genus-specific invA gene from formalin-fixed paraffin sections. By using DNA templates extracted from tissue sections prepared from the aneurysmal site, conventional PCR protocol was able to detect the Salmonella-specific invA amplicon with the primer set designed to amplify a short flanking region (107-bp) within the open reading frame of invA. The detection of pathogen-specific genes from various resources may serve as a diagnostic adjunct for determining the etiology of deep-seated infections, even when there are solely autopsy materials available. |
