An unusual complication in the development of ringworm has led some scientists to question whether the condition was triggered by a genetic defect or environmental factors.

Scientists in Japan say they’ve found that the ringworms that appear on the skin of infected children have gone extinct in a large number of cases.

Scientists are puzzled by the fact that ringworm can appear on children without any symptoms, such as the itchiness or other symptoms associated with the disease.

Ringworm was first discovered in the U.S. in 1991.

It’s an infectious infection caused by a bacterium called Rhodobacterium spirochaetes, which is present in soil, dust, and other surfaces.

The virus attacks and kills cells that produce the body’s own antibodies to protect the host from infection.

Although most people do not get the disease, ringworm causes significant problems in children.

Rhodobacteriosis can be spread by contact with contaminated surfaces and from infected people, as well as through contaminated food.

According to the Centers for Disease Control and Prevention, about 1.3 million Americans have ringworm.

Most adults don’t get the condition, which can cause severe headaches, joint pain, and fatigue.

Researchers have been studying the condition since the 1980s, but have yet to identify a cause.

Until recently, scientists thought that the virus could be responsible for the ring worms, which have been spotted in the lungs of children.
