Birds use herbs to protect their nests

27.05.2004


Researchers from Ohio Wesleyan University suggest that some birds may select nesting material with antimicrobial agents to protect their young from harmful bacteria. They present their findings at the 104th General Meeting of the American Society for Microbiology.



"If the fresh herbs and plant materials that parent birds bring into the nest have a sufficient concentration of antimicrobial compounds, they could protect the nestlings from harmful bacteria," says researcher Jann Ichida.

To find out if plants brought into the nest might prevent disease, Ichida and colleagues tested twelve different volatile plant materials against feather-degrading bacteria. Results showed that several types of plant materials and extracts including usnic acid, ascorbic acid, yarrow, and two oak species inhibited the growth of a number of harmful bacteria.


"If the fresh herbs have a sufficient concentration of these chemicals, they could protect the nestlings from harmful bacteria," says Ichida. "By practicing medical botany, parent birds exercise effective home nest security and protect their offspring from select biodegrading microbes that affect the health of their young."


This release is a summary of a presentation from the 104th General Meeting of the American Society for Microbiology, May 23-27, 2004, in New Orleans, Louisiana.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
