Molecular Identification and Typing of Enteroviruses Isolated from Clinical Specimens

Identification of enteroviruses in clinical specimens by competitive PCR followed by genetic typing using sequence analysis.

A sensitive method based on competitive PCR was developed to detect and quantitate enteroviral RNA in clinical specimens, with special emphasis on controlling contamination and the presence of potential inhibitory factors in the specimens. Oligonucleotide primers from the conserved parts of the 5' untranslated and VP2 capsid protein-coding regions were selected to differentiate between enterovi...

PCR and RFLP Analysis for Identification and Typing of Helicobacter pylori Strains from Gastric Biopsy Specimens

Preliminary identification of mycobacteria isolated from clinical specimens.

From March 1979 to June 1980, we preliminary identified mycobacteria at the time of their initial isolation by colonial morphology, pigmentation, and growth rate. The definitive identifications were predicted accurately for 92% of the mycobacteria isolated from 108 patients. For laboratories that isolate relatively few different species of mycobacteria, the advantages of this approach are its s...

Identification of viridans streptococci isolated from clinical specimens.

Of 532 strains of viridans streptococci isolated from clinical specimens, 517 were identified by using a scheme based on the work of Facklam (R. R. Facklam, J. Clin. Microbiol. 5:184-201, 1977). The strains were distributed among nine of the species described by Facklam and an additional group of physiologically homogeneous streptococci not recognized in Facklam's scheme. The method for identif...

Antibiotic Resistance Patterns and Molecular Typing of Acinetobacter Baumannii Strains Isolated from Burn Patients in Iran

Background and Aims: Acinetobacter baumannii (A. baumannii) is an important multidrug-resistant opportunistic pathogen frequently causing various nosocomial infections and is a serious threat to burn patients. These infections are usually caused by the outbreak strains. The aim of this study was to show antibiotic resistance pattern and molecular typing of A. baumannii genes isolates collected ...
