While the bacterium has been recognized to cause Johne's disease for more than 100 years, methods for satisfactory diagnosis, treatment and prevention are lacking" (Scientists Crack Genome Sequence Of Major Dairy Pathogen 2002). This problem would not have aroused studies and researches a few centuries ago. This study would not have been conducted in other countries because almost all the world's countries and their people possess unifying attributes that make them distinct and unmistakable for any other nationality, race, culture and language. Therefore, by understanding that sheep's make up is a valuable organism whose genome has been sequenced so that there is a greater knowledge of human make up. From there, by understanding the genome sequences of a sheep, researchers can gain further insight into human genome sequences. In most cases, using virtual sheep is more in-depth for some researchers rather using real sheep. "The real sheep genome sequence assembly covers approximately...

are not mappable and are not displayed. In contrast, the virtual sheep genome contains markers, BAC-end sequences etc. mapped using comparative approaches and therefore is much more comprehensive in it's coverage" (Sheep Genomes 2001). With that, it has become easier to break down the human genome sequences after having an in-depth analysis of sheep genome sequences.
