A number of commercial assays are available which use different molecular approaches to amplify and detect MTBC.
We used different molecular approaches as has been done i.e. for tumorigenesis in different p53 genetic backgrounds before [ 14, 15].
By using different molecular and genetic approaches, including a mutagenesis screen, several genes have been identified that regulate the response of this organism to acute anoxia (i.e., tps1 [7], ADAR [6], [8], and fau [9]).
Emergence of MRSP has led to several investigations of the phylogenetic background, diversity and clonal distribution using different molecular and phenotypical approaches e.g. [ 5- 8, 27].
In addition, studies using different molecular methods and more sophisticated approaches for assessing mutations in minor populations of malignant cells should be performed.

After previous demonstration of Y. pestis Orientalis-type multiple spacer type sequences in Justinian and medieval specimens (5 ), we now have cumulative evidence using 2 different molecular approaches that Y. pestis closely related to the Orientalis biotype was responsible for the 3 historical plague pandemics.
Using a different molecular approach, Irie and Sehara-Fujisawa (2007) also provide evidence for the vertebrate phylotypic stage.
It may be that these differences can be explained by the use of different molecular approaches.
