Scientists Discover Gut Bacteria That Improve Bee Memory

London [UK], November 25 (ANI): An international research team has discovered certain types of gut bacteria in honeybees that can improve memory.

Led by scientists at Gangnam University in China in collaboration with researchers at Queen Mary University in London and Oulu University in Finland, the study is a gut microbiota species known as lactobacillus apis in the memory of Bumblebee. Shown to be related to enhancement.

Researchers have shown that bumblebees, which are high in this type of bacteria in the intestine, have better memory than individuals with low bacteria. We also found that bumblebees that ate foods high in this type of intestinal bacteria had longer memory lasts than those who ate a normal diet.

To test the memory and learning abilities of honeybees, researchers created artificial flowers of different colors. Five colors were associated with a sweet sucrose solution, and the other five were associated with a bitter solution containing the bee repellent quinine.

Next, the researchers observed how quickly the bees were able to find out which color was associated with sugar rewards, and whether they were able to retain this information in a follow-up test three days later.

By sequencing honeybee intestinal samples, individual differences in bumblebee learning and memory abilities could be compared to the levels of various bacteria found in the intestine.

To confirm that the number of Lactobacillus apis in the gut is directly involved in the observed memory differences, researchers added these bacteria to the bumblebee diet and measured their response to the same task. bottom.

This study, published in Nature Communications, increases evidence that the gut flora (trillions of microbes that live in the gut) can affect animal behavior.

The cognitive abilities of bees vary from individual to individual, and the relatively small community of gut microbiota compared to mammals makes them an ideal model for investigating the role of specific gut microbiota in cognitive differences between individuals. I am.

Researchers suggest that the microbiome variability observed between individual bumblebees may result from differences or changes in nest environment, activity, pathogens, social interactions, and pollination environments. ..

Dr. LiLi, the lead author of the study and a postdoctoral fellow at Gangnam University, said: The same bacterial species as the bee diet can enhance their memory. “Further research is needed to determine which bacterial species have the same effect on humans and which bacterial species have the same effect.” Chitka of Queen Mary University in London said, “This is. A fascinating finding that may apply to humans as well as honeybees. Our findings increase evidence of the importance of intestinal-brain interactions in animals, and natural bacterial populations. It provides insight into the causes of cognitive differences in London. “” It’s amazing to find a specific memory-enhancing bacterial species. The result is that we have the cognitive ability to regulate the intestinal flora. ” rice field.
