tapeworm is not new to the medical world. The latest one is turned out tapeworm can infect humans with tumors.
Scientists from the Centers for Disease Control shocked to find 'a disease like cancer is discovered on a man aged 40 who is believed to come from tapeworms.
The discovery of a case
In January 2013, a Colombian man see his doctor and complained because it always feels tired, fever, cough, and experienced a significant weight loss. Doctors later found that the man heavily infected tapeworm known as Hymenolepis nana and grow many tumors in many organs.
A biopsy tests found that the lung and spleen the man filled with tumors that any doctor had never seen. The tumor size 10 times smaller than human cancers.
"These tumors are similar to cancer in humans, but the CDC laboratory studies conducted found that the cancer-like tumor that is not from men," according to a CDC statement quoted from the Medical Daily,
The set of tumors appeared to have the same DNA as the tapeworm in his body.
The discovery that has never existed before
Initially, the researchers were not sure of what they are facing, said Atis Muehlenbachs, a CDC pathological study of a special unit strange diseases. When talking to the Washington Post, Atis revealed that these cells have a pattern similar to cancer cells, but united in a way that is very unusual for human cells. Researchers originally thought such cells is a newly infected organism, but after discovering that cell contains the DNA Hymenolepis nana, they realize that they face a completely different thing.
"In the early months, we wonder if this is a human
cancer cells is unusual, or infection arising from protozoa-amoeba-like cells." Said Muehlenbachs. "Finding that these cells contain DNA tapeworm is a big surprise, it was very surprising," he continued.
He said this case represents the first time the CDC saw cancer cells caused by parasites spread in the human body.
Although previously known viruses and bacteria capable of causing a person to cancer, such as human papillomavirus 'famous' as the cause of cervical cancer and the bacteria Helicobacter pylori is able to cause stomach cancer. However, before this no one knew that tapeworms can cause such a scary thing.
"This is a rare occurrence," said Muelenbachs told NBC News. "However, tapeworms can be found in humans around the world who have a disease that attacks the immune system such as HIV. So the possibility of other cases that have not been found to be very large. It requires further research, "he said.
await developments
The discovery of this case for concern. Scientists have long known some few animals are very susceptible to cancer, while others are almost immune to the disease. However, until now, there has been no evidence found that the parasite found in humans may give cancer cells. American Cancer Society knows that certain parasites were able to increase the human risk for cancer, but not as a carrier of the cell itself.
The invention is also directed question back to what the true cause cancer, and whether other organisms that live in humans are also capable of moving the mutant cells. The Washington Post reported that scientists have stressed that the body of the ecosystem of the human body is made only from 10 percent human cells and 90 percent longer made of microbial cells.
Although the ability to move certain microbes are still unclear, the CDC did not find any risk of the cancer cells tapeworm can be transmitted from human to human.
This case should have been able to spur their deeper research to diseases like this cancer, and the ability of parasites and other microbes in transmitting the disease.
"The interaction of parasite and host that we have just reported is supposed to stimulate a deeper exploration of the relationship of infection and cancer," says the author of the CDC report.
