The main purpose of microbial typing is to evaluate the relationships between microbial isolates. Microbial typing can use for identifying the source of infection by detecting a clonal link between the strains. Moreover, it can analyze outbreaks, antimicrobial-resistant strains, and evaluate the effectiveness of control measures so, the efficiency of monitoring systems would increase. HAIs can affect hospitalized patients in all age ranges with any clinical situation, and lead to death. Molecular epidemiology is useful to determine genetic relatedness between isolated pathogens from patients, and design proper prevention plans to prevent infection through the hospital and community. Nowadays, typing methods for a wide range of bacterial strains are known as essential epidemiological tools to prevent and control infections in hospitals and communities. Although basic typing methods were more focused on phenotypic techniques like antibiogram and serotyping, new methods are based on molecular techniques including PCR-based methods and sequencing-based methods. Due to the high frequency of methods, choosing the right one for research applications seems difficult and requires basic knowledge about all of them. In this review, we aim to introduce the most useful and practical molecular typing techniques. Also, their utilization, advantages, and disadvantages were compared.

Letters to Editor
Given that CMBR Journal's policy in accepting articles will be strict and will do its best to ensure that in addition to having the highest quality published articles, the published articles should have the least similarity (maximum 18%). Also, all the figures and tables in the article must be original and the copyright permission of images must be prepared by authors. However, some articles may have flaws and have passed the journal filter, which dear authors may find fault with. Therefore, the editor of the journal asks the authors, if they see an error in the published articles of the journal, to email the article information along with the documents to the journal office.
CMBR Journal welcomes letters to the editor ([email protected]) for the post-publication discussions and corrections which allows debate post publication on its site, through the Letters to Editor. Critical letters can be sent to the journal editor as soon as the article is online. Following points are to be considering before sending the letters (comments) to the editor.
 Letters that include statements of statistics, facts, research, or theories should include appropriate references, although more than three are discouraged.
 Letters that are personal attacks on an author rather than thoughtful criticism of the author’s ideas will not be considered for publication.
 There is no limit to the number of words in a letter.
 Letter writers should include a statement at the beginning of the letter stating that it is being submitted either for publication or not.
 Anonymous letters will not be considered.
 Letter writers must include Name, Email Address, Affiliation, mobile phone number, and Comments
 Letters will be answered as soon as possible
