what are the causes of Lobo's blastomycosis and what are the causes of Lobo's blastomycosis

The main etiology of blastomycosis is caused by tuberosporum Loboa

First, the cause of the disease

There have been several reports of Robertinia infecting dolphins, suggesting that its life history includes saprophysis in watery environment. The artificial culture of this strain needs to be improved and the yield of animal inoculation is very small. Its pathogenicity is very low, and infection may be related to trauma.

Second, the pathogenesis

Infection may be related to trauma. Pathogenic bacteria enter the skin along the wound, and produce nodules at the invasion, which are higher than the skin surface, brown or purplish red, with smooth and elastic surface and no flush around, and the damage is often concentrated in one place. With further reproduction, through self-spread or self-inoculation, the damage gradually increases, and the conscious symptoms are mild, slightly itchy and painless, similar to benign tumors or keloids. In a few cases, due to trauma, there may be ulceration and exudate, and the surface is scabbed. Occasionally, it can spread through lymph nodes, resulting in enlargement of nearby lymph nodes, but no involvement of mucous membranes, viscera and bones.
