Giardia intestinalis can cause disease in several different mammalian species, including humans. Giardia organisms G. intestinalis) that infect humans are similar morphologically to those that infect other mammals; thus, they have been considered a single species, though other species in the Giardia genus infect other organisms. However, G. intestinalis has been divided into different subgroups based on their host and a few other characteristics.
In 1999, a DNA sequence comparison study tested the hypothesis that these subgroups actually constitute different species. T following phylogenetic tree was constructed from the sequence comparison of rRNA from several subgroups of G. intestinalis few other morphologically distinct species of Giardia. The researchers concluded that the subgroups of Giardia are sufficiently different from one another genetically that they could be considered different species. T. Monis et al. 1999.

Definitions:

Computing Depreciation

The process of systematically allocating the cost of a tangible asset over its useful life, representing how much of the asset's value has been used up.

Units-of-production

A depreciation method that allocates an asset's cost based on its usage, output, or units produced, rather than the passage of time.

Salvage Value

The estimated residual value of an asset at the end of its useful life, after accounting for depreciation or amortization.

Depreciation Expense

The allocated amount of an asset's cost over its useful life, used to account for declines in value over time.
