CVD Disease and your Oral Flora
Among the collection of microbes that live with us are the ones inside our mouths. Between 8 and 20 billion microbes representing 700 species of bacteria, fungi, viruses and archaea live there. Studies have shown that poor oral hygiene leads to changes in oral microbiome that directly links to cardiovascular disease.

Even One Course of Antibiotics Can Alter Your Gut Microbiome for Years
While antibiotics save lives, long term or repeated use of it is linked to obesity, type two diabetes, heart disease and even cancer – likely because they disrupt our gut microbiome. A single course of antibiotics causes drastic changes within days and a big drop in the diversity of the microbes. And a new study reveals that certain antibiotics cause changes that can last four to eight years.

A New Tick Spit Protein is a Potent Immunomodulator
Behind mosquitos, ticks pose the greatest health risk to us among all creepy crawlies and animals. They can transmit microbes that cause serious diseases such as Lyme disease and babesiosis, an infection of red blood cells. Ticks pass on pathogens when they latch onto our skin using their mouths to feed on our blood. Proteins in their saliva immobilize our immune response, and scientists have been studying this mechanism for ways to manipulate it to our benefit.

Just in the US, we would have had one and a half times more infections, nearly 4 times more people hospitalized, 4 times more deaths, and more than $1 trillion in added medical costs.
