Altogether 786 isolates from time interval 2008-2010 were grouped into 90 PCR ribotypes and eleven of them were shared among all host types and the environment. Ribotypes that were most common in humans were also present in water and different animals (014/020, 002, 029). Interestingly, non-toxigenic isolates were very common in the environment (30.8%) in comparison to humans (6.5%) and animals (7.7%). A high degree of similarity was observed for human and animal isolates with PFGE.
There are six types of asbestos minerals that occur naturally within the Earth's environment. The Environmental Protection Agency (EPA) has classified the types as such: Chrysotile : Chrysotile is one of the most common and most dangerous forms of asbestos found within our Earth. This type of asbestos accounts for approximately 90 percent of commercially-used asbestos in the world. Chrysotile asbestos fibers are long, white, and curly. Amosite : Amosite asbestos is recognized by its straight fibers and brown color. Amosite asbestos contains iron and magnesium, and was most used within different types of insulation products.
