The parasite in the bug bugs sucks blood that has been spread through mice

Trypanosoma-like blood-born parasite has been identified in the stink bug. Recently, scientists have also infected this parasite to white mice and only 48 hours later, in the body of the white mice infected.

Talking to VietNamNet on September 12, Dr. Truong Xuan Lam, Head of Experimental Insects at the Institute of Ecology and Biological Resources, Vietnam Academy of Science and Technology, said that he and his colleagues have taken blood in the stink bug sucked blood collected from the local people last time and directly injected about 40 white mice.

As a result, only 48 hours later, parasites of stink bugs were found in rat blood. That suggests, parasite adaptation to mice is very fast.

People indifferent .

Although there are no specific research results in Vietnam about this species, the collected samples of Dr. Lam are gradually increasing in the laboratory.

On the afternoon of September 10, the whole Nhan (85 years old) in hamlet 8A, Dong A village, Co Nhue commune, Tu Liem, Hanoi removed firewood to prepare dinner, and found 3-4 stink bugs. He quickly took a few sticks of firewood nearby to beat the stink bug constantly and saw the blood in the kitchen.

Seeing the beating tool like that, Mr. Dien (70 years old) came and went to see it and found that it was a kind of bug that sucked human blood - Mr. Dien himself had been burned twice before. Mr. Dien entered the kitchen area of ​​the kitchen. Removing a few sticks of wood, he still caught about 10 animals and put them in a bottle of lavie.

About 2 hours later, he received information that Dr. Truong Xuan Lam went to the scene to collect stink bugs. Stunned and surprised when the firewood was removed, the bugs came there, much unspeakable.

For decades, Nhan cooks in that kitchen and firewood are regularly bought and kept in addition, so they don't pay attention to it. Seeing a cow beetle, it was only beaten to death even though every time he saw blood, he didn't pay attention.

The bug bug was unloaded, and the shocked man recounted: "I do n't know how many children I have to say, but I have to go to a basket, brown-black-brown at a time of great fear ."

Nhan also added: "The kitchen in which the mouse kept running and running back and forth in the absence of people," acted "I am terrible! ".

Dr. Lam was also surprised and said, this is the biggest drive ever obtained with about 270 children all kissing bugs. " These stink bugs may not have been burned, but there are mice, lots of mice ," said TS. Lam said.

Mr. Nguyen Van Quynh, a person living nearby and also a doctor. Truong Xuan Lam considered the collaborator said that he once caught bugs directly in a bottle in his house. A few steps away, in June, his cousin Duan (from Quang Ninh) came to live with him - staying at Uncle Quynh's house - so that the university exam was once burned.

Functional industry . left open?

Most of the people in the districts in Hanoi city have never heard of the functional industry warning about this species of bugs, but mainly know the information through mass media.

Mr. Nhan had seen this bug when he boiled firewood and just died, but he had never heard of this insect and its harm before.

Mr. Quynh shared that there were also some people around the village, but there were no harms because the burned people found swelling and tiredness for about a week without serious symptoms. they are indifferent. Even, Mr. Quynh said, he also talked with the village health workers but they said that it was " unimportant " but now focused on preventing dengue fever, diarrhea, .

Until the afternoon of October 12, when we got to the scene where 270 stink bugs were caught (2 days ago), Nhan said that he did not see any village or commune functional branches spraying or moving. What is the outside of TS.Lam?

After sampling Nhan's house, Dr. Lam instructed the family to destroy all the habitat of this drive to kill the eggs. Also, note that people in that area must check the bed, small wooden slots.

And the kitchen is about 2m ² Nhan's house and some firewood were immediately " turned yellow " and the kitchen was built into the soil next to it.

Currently, in the laboratory of TS. Truong Xuan Lam is raising research on more than 400 kissing bugs from the local people in the past few months in Hanoi.

Previously, Mr. Lam said, the world has had a rather bad past for this insect. When the blood-sucking stink bug will transmit the parasite Trypanosoma cruzi intracellular causing Chaga's disease through blood. The disease becomes chronic, leading to death due to thrombosis .

However, there are no specific studies on this species in Vietnam. And these studies are just the start of the topic of the Department of Experimental Insects, assigned by the President of the Institute of Science and Technology.

The final goal of the study is to clarify, whether Trypanosoma-like blood-sugar parasites infect people.
