Unvaccinated Vaccinated babies

It is not a new idea that a mothers milk provides immune protection against a number of pathogenic agents via the transfer of antibodies, and indeed recently it was observed that the mothers immune defence plays a key role in the development of asthma and allergies in newborns and young children.

This process is known as “passive immunity”, however a team at the University of California have recently shown that breast milk can also contribute to the development of the baby’s own immune system by a process they are calling “maternal education immunity”.

Antibiotic ‘Last line of defence under threat’ say researchers

You may have read in the news recently that our last line of defence against bacterial infection has come under serious threat. While hospitals are already forced into using ‘last-resort‘ antibiotics, new research results suggest we may reach breaking point soon.

This final stand against the tide of antibacterial infection comes in the form of Polymyxin. A group of antibiotics with a general structure of a cyclic peptide and a long hydrocarbon tail. They kill bacteria by binding with lipids in the phospolipid membrane and thus disintegrating it. While this group of antibiotics was developed around 60 years ago they are rarely used. This is because they are both neuro- and nephrotoxic; affecting both the nervous system and the kidneys.

In some developing countries plants are still the only source of medicinal compounds with up to 80% of the population depending upon traditional medicines.
