Phytophthora ramorum
Trials of silvicultural methods for treating "P. ramorum" began in Humboldt County in northwest coastal California in 2006. The trials have taken place on a variety of infested properties both private and public and have generally focused on varying levels and kinds of host removal. The largest () and most replicated trials have involved removal of tanoak and bay laurel by chainsaw throughout the infested stand, both with and without subsequent underburning designed to eliminate small seedlings and infested leaf litter. Other treatments included host removal in a modified “shaded fuelbreak” design in which all bay laurel is removed, but not all tanoaks; bay and tanoak removal using herbicides; and removal of bay laurel alone. The results of these treatments are still being monitored, but repeated sampling has so far detected only very small amounts of "P. ramorum" in the soil or on vegetation in the treated sites.
Erythrasma
Recent research for Erythrasma is mainly focused on the treatments and which methods work best to treat the patient depending on the severity of the condition. In a 2016 study performed by Prathyusha Prabhakar and H. Hema, they looked into comparing 2% clotrimazole cream and 2% Fusidic cream in treating erythrasma. This was a one year long hospital based study in South India that resulted in stating that the groin was the most common site for the symptoms of itching and discloloration being predominant and also mostly in men. The general conclusion made was that topical 2% fusidic acid cream was found to be more effective than 2% clotrimazole cream in patients with erythrasma. The topical 2% clotrimazole cream was more effective only when an associated fungal infection was present.
