The findings of a new study have advanced significantly researchersknowledge of immunity for these pathogens. Information about the immune responses that occur in animals following haemoplasma infection is relatively unknown largely due to the fact that researchers struggle to study these bacteria as they are unable to grow them in the laboratory.

Lu says. his is slow, and obviously not ideal for the food industry. All these improvements contribute to the assay speed,

Thus, by sourcing from nature, we can adapt the platform to other pathogens and applications,

which proved effective in preventing surrogates of two well-known pathogens, Escherichia coli o157: H7 and Listeria monocytogenes, from attaching,

Since many other pathogens use the same host cell receptor for invasion the nanomimics might also be used against other infectious diseases.

In other applications bloodborne pathogens and other infectious agents could be minimized with antibiotic-carrying nanoparticles.

This capability should open up entirely new strategies for fields ranging from computer miniaturization to energy and pathogen detection n
