TB. Details concerning specimen collection and processing are also touched on. Bibliography lists 8 sources. SA136TB.rtf Tuberculosis to many
westerners is a throwback to another era, but from a scientific point of view, tuberculosis (TB) also seems out of character when examining twenty-first century medicine (Enserink, 2001). In other
words, it is something that should have been eradicated long ago. While most cases that crop up today are treatable, it still ranks among the worlds most serious infectious diseases
(2001). Still, TB has been controlled for the most part in well to do countries with a combination of vaccines, antibiotic treatment and screening processes (2001).
While there is a call for more effective vaccines, and treatment is certainly successful for the most part, screening processes have received a great deal
of attention. The sooner that TB can be diagnosed, the better. Rapid methods for detecting Mycobacterium tuberculosis have erupted and include new techniques which focus on Polymerase Chain Reaction, Ligase
Chain Reaction, Gas Chromatography, High Performance Liquid Chromatography, DNA sequencing, Nucleic acid amplification and hybridization, DNA Probes for Culture Confirmation, and IS6110 RFLP.
Kaul (2001) explains that nucleic acid amplification technologies like PCR have revolutionized the detection of infectious pathogens such as tuberculosis. Amplification technology can now provide the potential for diagnosing TB
in just a few hours with an adequate degree of sensitivity as well as specificity (2001). At the same time, molecular assays cannot replace or reduce the necessity for performing
a conventional smear and culture, speciation, in addition to antibiotic sensitivity assays (2001). Still, the sutlization of rapid methods provide some indication with a good degree of accuracy as to
