Researchers attempt to solve problems of antibiotic resistance and bee deaths in one

14.03.2012
The stomachs of wild honey bees are full of healthy lactic acid bacteria that can fight bacterial infections in both bees and humans.

A collaboration between researchers at three universities in Sweden – Lund University, the Swedish University of Agricultural Sciences and Karolinska Institutet – has produced findings that could be a step towards solving the problems of both bee deaths and antibiotic resistance.

The researchers have now published their results in the scientific journal PloS ONE and the legendary science photographer Professor Lennart Nilsson from Karolinska Institutet has illustrated the findings with his unique images.

Today, many people eat healthy lactic acid bacteria that are added to foods such as yogurt.

“In our previous studies, we have looked at honey bees in Sweden. What we have now found from our international studies is that, historically, people of all cultures have consumed the world’s greatest natural blend of healthy bacteria in the form of honey”, says Alejandra Vasquez, a researcher at Lund University.

In wild and fresh honey, which honey hunters collect from bees’ nests in high cliffs and trees, there are billions of healthy lactic acid bacteria of 13 different types. This is in comparison with the 1–3 different types found in commercial probiotic products, she explains.

The honey bees have used these bacteria for 80 million years to produce and protect their honey and their bee bread (bee pollen), which they produce to feed the entire bee colony. The researchers have now also shown that the healthy lactic acid bacteria combat the two most serious bacterial diseases to affect honey bees.

In the journal article, the researchers describe how the bees have these healthy bacteria in their honey stomachs and that they get the bacteria as newborns from the adult bees that feed them. The researchers have also seen that large quantities of harmful microorganisms such as bacteria, yeasts and fungi are found in the nectar and pollen that the bees collect from flowers to make honey and bee bread. These microorganisms could destroy the food through fermentation and mould in just a couple of hours, but in fact, the healthy bacteria in the honey stomach kill all the microorganisms.

“As humans have learnt to use honey to treat sore throats, colds and wounds, our hypothesis is that the healthy bee bacteria can also kill harmful disease bacteria in humans. We have preliminary, unpublished results which show that this could be a new tool to complement or even replace antibiotics”, says Alejandra Vasquez.

The present study also shows that bees’ healthy bacteria die when beekeepers treat bees preventively with antibiotics, which primarily happens in the USA. The bees have their own defence system against disease in the form of cooperative healthy bacteria. However, this system is weakened in commercially farmed bees that are treated with antibiotics, suffer stress, eat synthetic food instead of their own honey and bee bread and are forced to fly in fields sprayed with pesticides.

“Our results provide the research community with an undiscovered key that could explain why bees are dying worldwide in the mysterious ‘colony collapse disorder’”, says Tobias Olofsson.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
