As a greater number of research teams begin to use molecular technology rather than standard cultivation mechanisms to detect bacteria in their samples, it is becoming increasingly obvious why doctors and researchers are unaware that their patients with chronic inflammatory disease are infected with large quantities of L-form and biofilm bacteria – the techniques they are using to look for bacteria prove rather useless in actually identifying the pathogens.
This month yet another paper was published whose results confirm that the Petri dish is a thing of the past. The study, which was published in BMC Microbiology, used a series of molecular techniques to identify the species of biofilm bacteria present inside several different kinds of wounds.
Bioflims are formed when a complex and varied group of bacteria aggregate together inside a protective and adhesive protein matrix. The bacteria inside a biofilm cooperate to promote their own survival and the chronic nature of an infection. While dentists have long realized that bacteria in the mouth often reside inside biofilms – they form much of the goo that they remove from teeth – researchers are just starting to investigate bioflim communities that form in other areas of the body.

Could people 800 years ago have benefited from the Marshall Protocol? Did cave men suffer from infection with L-form bacteria? Nobody knows for sure when these stealthy pleiomorphic bacteria first began to infect human beings, but a new study published in the Proceedings of the National Academy of Sciences by researchers at Pennsylvania State University suggests that Th1 disease was already common during the middle ages.
The team analyzed 490 skeletons from a London cemetery for Black Death victims – the name given to those people who succumed to the plague epidemic of 1347 to 1351. Black Death – named after the black spots the bubonic form of the plague caused on the skin – was one of the deadliest recorded in human history, killing about 75 million people, according to some estimates, including more than a third of Europe’s population.

For decades, scientists working with L-form bacteria have warned that the pathogens are not killed by the purification processes used when pharmaceutical companies creates vaccines. A recent drug trial by Merck and Co., Inc. suggests that the failure of mainstream medicine to take the presence of L-form bacteria seriously has put a large group of people of people for developing a wide range of chronic diseases.
Several months ago, two international trials aimed at testing an experimental AIDS vaccine were stopped after it became clear that the vaccine did not prevent infection with the AIDS virus. The trials were conducted in the United States, Peru, Brazil, Dominican Republic, Haiti, Jamaica, Australia and South Africa. Today, the researchers conducting the trial are faced with another problem. Earlier this month they reported “worrying” indications that the thousands of people who received the vaccine are now at greater risk for infection. They have already begun counseling volunteers about the fact that they could be at higher risk for acquiring HIV – the fatal and incurable virus that causes AIDS.

“Bacterial L-forms are among the most unusual creatures in nature. Once one has seen their strange habits and life style, one starts to work on L-forms with great enthusiasm because their existence in vivo and in vitro gives rise to more questions in classical microbiology, immunology and infectious diseases.
Researching L-forms is like trying to catch a fish that appears on the surface and quickly dives back into the sea. It is almost impossible to catch it with bare hands. There are better chances of catching the fish by hook and line but chance is always powerful when efforts are joined and fishing nets are put into use.”
And just who is able to describe the process of culturing L-form bacteria so eloquently? She’s an Associate Professor at the Department of Pathogenic Bacteria Institute of Microbiology at the Bulgarian Academy of Sciences, who’s worked with L-form bacteria for the last 15 years. Meet Nadya Markova.

I graduated as a medical doctor, but my interest in microbiology led me to the Bulgarian Academy of Sciences (where I defended my PhD thesis in the field of medical microbiology). Researchers already working there at the time had great experience in L-form research and had made many interesting observations about the bacteria, all of which sparked my interest. They were my teachers, who inspired me to continue their research in the same field.
I started thinking about how L-form bacteria change form in the beginning of the 90s, and my interest in them has risen ever since. Unfortunately, our research team is comprised of only 5 people. One of them must be mentioned, my teacher Professor Lilia Michailova. She is an excellent electron microscopist and, without her, our achievements wouldn’t have been possible. I’m really glad that she is still active and that we continue to work together.

A wide body of research has shown that classical forms of bacteria often transform into tiny variants of the same species, losing their cell walls in the process. They are then referred to as L-form or cell wall deficient (CWD) bacteria. Although researchers have known about L-form bacteria for over a century, up until recently they have not fully understood their connection to chronic disease. It is now known that these bacteria are responsible for causing a wide array of chronic diseases including rheumatoid arthritis, Chronic Fatigue Syndrome, Lyme disease, and sarcoidosis.
Over the past century researchers have identified over 50 different species of bacteria capable of transforming into the L-form and it is likely that even more species will be discovered in the coming years. The vast majority of researchers and doctors are not aware that L-form bacteria are present in their patients because the pathogens will not grow under standard laboratory conditions and must be cultured in a different medium and at a different temperature than classical bacteria.
In 2005, a team of researchers at the Royal Brompton Hospital in London published a paper that reviewed the clinical significance of the L-form as an infectious agent. The review discussed the work of hundreds of researchers who have cultivated the L-form and implicated it in a wide array of diseases.
