While 16S rRNA sequence-based identification of Nocardia species has become the gold standard, it is not without its limitations. We evaluated a novel approach encompassing the amplification of the Nocardia 16S-23S rRNA intergenic spacer (IGS) region followed by fragment analysis by capillary gel electrophoresis (CGE) of the amplified product for species identification of Nocardia. One hundred ...
16S rDNA sequence analysis is the most accurate method for definitive species identification of nocardiae. However, conflicting results can be found due to sequence errors in gene databases. This study tested the feasibility of species identification of Nocardia by partial (5'-end 606-bp) 16S rDNA sequencing, based on sequence comparison with "reference" sequences of well-annotated strains. Thi...
A bacterial isolate (IMMIB R-145(T)) from a human abscess was subjected to a polyphasic taxonomic study. Chemotaxonomic investigations revealed the isolate to have cell wall chemotype IV and mycolic acids consistent with characteristics of the genus NOCARDIA: Comparative 16S rRNA gene sequencing showed that the isolate constituted a distinct subline within the genus Nocardia, displaying greater...
Nocardia infection following anterior cruciate ligament (ACL) allograft reconstruction is a rare occurrence. We report a case of Nocardia infection of an allograft ACL reconstruction and septic arthritis of the knee joint due to an organism most similar to the novel Nocardia species Nocardia aobensis.
A soil isolate, strain F829T, which had provisionally been assigned to the genus Nocardia, was subjected to a polyphasic taxonomic study. An almost complete 16S rDNA sequence was determined for this strain; the sequence was aligned with available sequences for nocardiae and phylogenetic trees were inferred using three tree-making algorithms. The organism showed a combination of phenotypic prope...
identification of clinically significant nocardia species is essential for the definitive diagnosis, predict antimicrobial susceptibility, epidemiological purposes, and for an effective treatment. conventional identification of nocardia species in routine medical laboratories which is based on phenotypic (cellular morphology, colonial characteristics), biochemical and enzymatic...
مقدمه: جنس نوکاردیا جزو اکتینومیستهای هوازی هستند که یک گروه بزرگ از باکتریهای ساکن خاک را شامل میشوند، که در جهان پخش شدهاند. در این مطالعه، با استفاده از آزمونهای تشخیصی رایج، مرسوم و مولکولی گوناگون، چندین ایزولههای نوکاردیا جداسازی و تشخیص داده شد. مواد و روشها: در این پژوهش، برای جداسازی از خاک، روش slip-buried و برای استخراج dna، روش microwave oven استفاده شد و در این روشها، سویه...
Authors of the present letter reviewed the letter conducted by Fatahi-Bafghi entitled as "Phenotypic and molecular identification of nocardia in brain abscess."[3] Nocardia is a filamentous bacteria, branched Gram‐positive Bacilli, aerobic, and partially acid-fast, and its diagnosis depends on staining and culture.[4] In this case, microscopic study of the brain abscess specimen revealed, long ...
New methodologies were developed for the identification of Nocardia but the initial diagnosis still requires a fast and accurate method, mainly due to the similarity to Mycobacterium, both clinical and bacteriologically. Growth on Löwenstein-Jensen (LJ) medium, presence of acid-fast bacilli through Ziehl-Neelsen staining, and colony morphology can be confusing aspects between Nocardia and Mycob...
Nocardia is an opportunistic pathogen that causes respiratory infections in immunocompromised patients. The aim of this study was to analyze the epidemiology, clinical significance and antimicrobial susceptibility of Nocardia species isolated from eight children with cystic fibrosis. The isolated species were identified as Nocardia farcinica, Nocardia transvalensis, Nocardia pneumoniae, Nocardi...
