I always remember that I am a temporary visitor in a living and vibrant landscape; a landscape that offers both guest and host alike the necessary support as we measure our progress towards a planned, but ultimately unknown, destiny.
To our experience, it is of utmost importance to first set up a local database hosting only the necessary data.
To construct case and control groups, the analyst has to specify a logical expression based on which the hosts perform the necessary comparisons and output the two index vectors in secret shared form.
By losing its dependency on tsetse flies, which are ecologically restricted to a specific area in Africa, T. evansi has travelled unlimited distances and found vicariant hosts and the necessary reservoirs and vectors for its successful expansion.
Even if specialization is a pervasive pattern, the process is not irreversible and occasional episodes of host expansions could conceivably generate the necessary variation in host use to drive speciation.
Further studies to determine if biofilms also occur in vivo, i.e. on the surfaces of the respiratory tract in M. bovis infected calves, and if or how they contribute to the persistence of the agent in the host, are necessary.
While it is reassuring that the reservoir for Lassa virus is M. natalensis, as reported in the literature since the 1970s, our study demonstrates that proper taxonomic identification of the host is necessary before drawing inferences about the ecology of Lassa virus infection.
And these changes in host use may be the necessary injection of new variation that facilitates diversification [5], [9].
Occasional lateral transmission events, bringing two distinct bacterial symbionts together in the same host background, would provide the necessary opportunity for recombination in this lineage leading to this observed result: a mosaic of evolutionary histories throughout the genome [ 32].
On the host all necessary information is extracted from the data.
