Genetic Diversity

According to certain characteristics, two groups of have been described in Europe as Polish and Belgian. In the United States, the designations are groups I and II, and in Australia the groups are called assemblages A and B or genotype A and B.[17-19] Molecular studies have also revealed the existence of genetic differences within assemblage A, named Cluster AI and AII. The latter has been isolated only from humans. Molecular analyses showed that the genetic distance partitioning these two assemblages can be used to delineate other species of protozoa. Nevertheless, at present, two important questions are posed: ''Is giardiasis a disease of animals that is transmitted to humans (zoonosis)?'' and ''What is the taxonomic status of the parasitic protozoan species isolated from humans and animals?'' because molecular analysis shows that the same Giardia genotype can be found in humans as well as other mammalian species.

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.
