Subcutaneous mycoses are rare and cause the spread of fungi when they enter the subcutaneous area. A common cause of such infections is Sporotrix schenckii, which causes sporotrichosis. This fungus spreads in soil, flowers and tree bark and causes infections mainly in gardeners, farmers and agricultural workers as a result of skin damage. After an incubation period of 1 week to 6 months, a small papule or nodule forms at the entrance door of the infection, which is accompanied by the formation of new nodes along the course of lymphatic vessels.
Mutation and selection.
Mutations are hereditary changes in the genotype that can occur spontaneously or be caused by chemical or physical treatment.
Exchange of genetic information.
Bacterial conjugation is the transfer of genetic material (plasmids) between bacterial cells by direct contact from cell to cell or by forming a bond between two cells. During conjugation, the donor cell provides a conjugating or mobilizing genetic element, most often a plasmid or transposon. Most conjugating plasmids have systems to ensure that the recipient cell no longer contains such an element.
The transmitted genetic information often benefits the recipient. Benefits may include antibiotic resistance, tolerance to xenobiotics, or the ability to use new metabolites. Bacterial endosymbionts can be considered such useful plasmids.
Viral infections of the skin.
Viruses that damage the skin can penetrate and then develop in the skin or cause damage after their systematic spread in the body. Those that remain in the skin include HPV (cause warts) and the smallpox virus, which causes the skin disease Moluscum contagiosum (contagious or infectious mollusc). Certain types of papillomaviruses have adapted to life in certain areas of human skin, which has led to the appearance of plantar warts, as well as warts on the fingers, knees and perineum.
Viruses harmful to the skin include:
Viruses such as herpes simplex, chickenpox, shingles and many others that can lead to the formation of vesicular skin lesions caused by the multiplication of viruses in them. Due to the presence of viruses in vesicles, they can be transmitted to another person through direct contact with them and are called infectious vesicles. スポーツベッティングがさらにエキサイティングになる ブックメーカー へようこそ。さまざまなイベント、高オッズ、多数のボーナスをご用意しています。当社のお客様は、信頼できるサポート、迅速な支払い、データのセキュリティを信頼できます。お気に入りのチームに賭けて、一緒に勝ちましょう!
