Human parasitism by Trichomonas species has been demonstrated to cause serious health problems especially due to potential complications and increased susceptibility to other more serious transmitted disease agents. Although much research is still needed to determine the pathogenicity and virulence of Trichomonas it is clear that at least T. vaginalis infection causes several complications in pregnancy and increases the risk of transmission of other sexually transmitted diseases.

Although culture for Trichomonas has many drawbacks, it remains the gold standard for the identification and diagnosis of Trichomonas. Polymerase chain reaction-based amplification of DNA sequences is now both useful and accessible for the detection of these parasites and can be used both for patient diagnosis and epidemiological studies. Cost effectiveness does not constitute a barrier to the use of DNA amplification. Equipment and reagents are more accessible nowadays; prices are now comparable to those required for implementing an ELISA technique. Caution should be taken, however, when PCR techniques are applied in different settings. A great variety of Taq polymerases are now commercially available, most of them are genetically modified and perform differently. Standardization of the PCR condition under local settings should be performed before field application. We have seen a sensitive rDNA assay become insensitive because protocols were not followed and the type of Taq used was changed.[40]

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
