For example, Microsporum audouinii was the predominant etiological agent in North America and Europe until the 1950s, but now Trichophyton tonsurans is more common in the US, and becoming more common in Europe and the United Kingdom. This shift is thought to be due to the widespread use of griseofulvin, which is more effective against M. audounii than T. tonsurans; also, changes in immigration patterns and increases in international travel have likely spread T. tonsurans to new areas. Another fungal species that has increased in prevalence is Trichophyton violaceum, especially in urban populations of the United Kingdom and Europe. See also

Guinness Book of World Records
On 10 December 2010, the Guinness Book of World Records rested its "longest dreadlocks" category after investigation of its first and only female title holder, Asha Mandela, with this official statement:

Following a review of our guidelines for the longest dreadlock, we have taken expert advice and made the decision to rest this category. The reason for this is that it is difficult, and in many cases impossible, to measure the authenticity of the locks due to expert methods employed in the attachment of hair extensions/re-attachment of broken off dreadlocks. Effectively the dreadlock can become an extension and therefore impossible to adjudicate accurately. It is for this reason Guinness World Records has decided to rest the category and will no longer be monitoring the category for longest dreadlock. See also
