Cell culture and neutralization have been considered the gold standard for enterovirus detection and identification for more than 50 years, but molecular amplification technologies are rapidly replacing the traditional methods in clinical and public health laboratories. Assays based on reverse transcription–polymerase chain reaction or nucleic acid sequence-based amplification may be used to de...

Historically, a number of typing methods have been evaluated for Staphylococcus aureus strain characterization. The emergence of contemporary strains of community-associated S. aureus, and the ensuing epidemic with a predominant strain type (USA300), necessitates re-evaluation of the discriminatory power of these typing methods for discerning molecular epidemiology and transmission dynamics, es...

In this Round Table, the application of several methods of molecular typing were discussed in reference to four important pathogenic fungi: Coccidioides immitis, Histoplasma capsulatum, Candida albicans and Paracoccidioides brasiliensis. Among the different methods the following were discussed: restriction fragment length polymorphisms (RFLP), single nucleotide polymorphisms, random amplified p...

OBJECTIVES Mycobacterium intracellulare is the major causative agent of nontuberculous mycobacteria-related pulmonary infections. The strain typing of M. intracellulare is important for the treatment and control of its infections. We compared the discrimination capacity and effective value of four different molecular typing methods. METHODS Antibiotic susceptibility testing, hsp65 and rpoB se...

serology and dna techniques are employed for human leukocyte antigen (hla) typing in different transplant centers. results may not always correlate well and may need retyping with different technique. all the patients (with aplastic anemia, thalassemia, and immunodeficiency) and their donors, requiring hla typing for bone marrow transplant were enrolled in the study. serological hla typing was ...

Molecular epidemiology (ME), a blend of molecular biology and epidemiology, is very useful to study the spread of tubercle bacilli in mini epidemics, outbreaks, to analyse the transmission dynamics of tuberculosis (TB) and to determine the risk factors for TB transmission in a community. ME has a great role in distinguishing between exogenous reinfection and endogenous reactivation. In the labo...
