However, in a recent paper published in Environmental Microbiology, Dr Carla Pruzzo, Dr Luigi Vezzulli and Dr Rita R Colwell studied an environmental bacteria and it’s interaction with the environment and found that this provided them with vast amounts of information about how the organism causes disease.
The organism they studied was Vibrio cholerae – responsible for causing Cholera. In the aquatic environment this bacteria interacts with chitin, a naturally-occurring compound found in the cell walls of fungi, and in the exoskeleton of crustaceans and insects. This interaction in the aquatic environment was found to play a large part in determining how the organism survives, how it is spread and how it infects humans.
Dr Vezulli, one author of the study said:
“This knowledge provides a new framework for the understanding of the role of the non-human environment in affecting the spread of environmental disease-causing bacteria (pathogens), their evolutionary derivation and the way they infect humans to cause disease. This, in turn, can be applied to improve current approaches to risk assessments and epidemiology of infectious disease and to develop new responses for combating pathogens in the environment.”

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....
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....
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...
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...
