Our Opinion & Studies

Translated by Celine Thoma and Rachel Landau


General informations

The following observations are meant to inform and to encourage reflection. We do not pretend to know everything about the complex and complicated interdependency that exists between pathogens (viruses, bacteria, fungi, protozoa, parasites, etc.) and the corresponding virulence factors between those pathogens and the immune system of the affected person, which is systematically involved with all pathogenic agents. However, it is decisive (imperative) in every case to know if the affected person is only infected or if s/he really manifests the infection, i.e. if s/he is developing symptoms and how seriously s/he diseased.

We would like to invite everyone to join us in the research of this complex field and to share ideas. The attached studies in every single chapter were not performed nor commissioned by the BCA-clinic. The author only collected these studies for your information and presentation.


To start, we would like to give a few incentives for discussions:

  • It is known that some bacteria and viruses have developed mechanisms to modulate, bypass and mislead the immune system, in order to persist in the organism and hence, to reactivate later (e.g. HSV, HIV, VZV, EBV, TBC, etc.). Even the general medical opinion does not exclude anymore the possibility of a sub-clinical (latent) infection with borrelias.


  • It is known that some types of bacteria and viruses (or strains) are capable of creating pleomorphic forms and biofilms (even in vivo). Some can also modulate T-lymphocytes and induce insensitivity (anergy). It appears that not only viruses but also bacteria can have this same effect (Staphylococcus aureus – Deutsches Ärzteblatt, Jg. 106, magazine # 43 – 28/10/2011, page 1902). Some pathogens are able to change their antigens and receptors on the surface, to block or are resistant against the complement system of the affected person, or even to „mislead“, for instance, the TH-system. Many of those mechanisms are also known to exist undeniably among the borrelias (1),(2),(7),(13).


  • Therefore, is it not possible that some auto-immune diseases (for an interesting articel, click here), allergies or endocrine diseases (malfunctions) can emerge? Normally, immune processes are triggered, pushed and maintained. Then, they must somehow be reduced and stopped. What if the permanent activation and/or disorder of the immune system are caused by the pathogens? Furthermore, it is also known that some pathogens can act upon the cerebral metabolism in order to cause dysfunction, for instance, in the metabolism of neurotransmitters (serotonin, dopamine, and noradrenalin). This can also happen through the inflammation that they cause. In this case, what could we say about some cases of depression?


  • There are many more factors that have an effect (often bad effects) on our immune system, such as environmental influences (specific food products, general diet, toxins, heavy metals, mould, softeners in toys and furniture, etc.). Hence, it is worth reflecting on the origin of our food in our globalized world of food industry and the conditions of production and processing. The media, for instance, reports more and more about these new methods (e.g. ethoxyquin used in salmon farming, antibiotics in animal breeding, etc.) Another interesting question would be regarding the methods used to manufacture our clothes (e.g. the tanning of leather using chromium, for instance) in countries of manufacture. Regrettably, there are many more environmental-medical factors that cannot be discussed in depths in this paper.


  • In cases of highly stressful situations and conflicts, it is known that our immune system may shut down (or weaken) due to a chronic overproduction of stress hormones such as adrenalin and cortisol. We can also include stress that the patient puts on himself, but also disturbances in the biological rhythm (e.g. night shifts), noise and infrasound. Any forms of stress have an effect. The reduction of those negative factors is surely helpful, but cannot be considered an exclusive and sufficient therapeutic approach.


  • Does our food still contain all necessary minerals and vitamins? Who actually can manages, in our busy life, to ingest those effectively?


  • Can a multi-systemic-disease, especially in case of a chronic course, be treated successfully with a short mono-therapy?


  • As mentioned before, we are familiar with the fact that some borrelia strains have the skill to modify or are resistant against the complement system of the affected person (1), (7), (13). This complement system is an important part of the innate immune system. This skill appears to be one important virulence factor of borrelia. A new study shows that this skill is distinctively strong depending on the borrelia strain (25).                                                                           We can deduce the following ideas from this:   A person becomes ill if the particular borrelia strain can block (or is resistent to) his/her complement system. If the borrelia strain is not capable of blocking (or not ressitant to) the complement system, then the patient is only infected but not sick. In both cases, we will be able to prove the presence of antibodies in the blood if the test method is efficient enough. The debilitated immune system, which results from the blockage of (or resistace to) the complement system, is a partial and functional weakness or ineffectivity of the immune system. There are no test methods to the date which can measure this; however, it does exist. The weakening (or ineffectivity) of the immune system is not as strong as for HIV, as borrelia only affects one part of the immune system. In the case of HI-virus, it is a massive and general weakening of the immune system. That we can measure. Wheather this ineffectivity of the immune system caused by borrelia has also an influence in other infections should be also investigated.


  • Why cannot humans develope persistent immunity against borrelia?


  • There are also interactions between the pathogens and strains (26).


An interdisciplinary and more complex consideration is necessary (holistic view) !

These points of discussion mentioned above are regularly documented in scientific studies of certain fields such as psychology, psychiatry, environmental medicine, occupational medicine, immunology, infection medicine and nutritional science.  However, the interdisciplinary intervention of all these factors and influences (a comprehensive observation) is missing in our understanding of disease processes and management of illness, because the patient is exposed to all those factors simultaneously, with varying intensities.  What does this mean, in summation, for the immune system, especially when the patient has a genetically weak immune system on top of all?


More incentives for discussions

  • The affected person is often exposed to several pathogens at the same time and the immune system is weakened by all these other influences. In the end, we human beings are constantly confronted and infected with a variety of pathogens throughout our lives, but we do not always get sick.


  • Could it be possible that some chronic infections may trigger multisystem and multi-organ disturbances that might also have multi-factorial origins that lead to the sickening of the infected? Therefore, do we not need individual, multimodal and holistic therapeutic approaches?


  • As we are all ‘unique’ in this world, surely we cannot expect everybody to react in the same way.  The immune system is the most important system in our ‘uniqueness’. The field of chronic infections (including Lyme disease) is probably much more complex than what initially presumed. It seems essential to gather and study literature from various areas, to use it as a “big frame” or in a different sequence in order to reach better understanding and causality. The possibility of a chronic (even bacterial) infection is, unfortunately, rarely considered.


  • A study of ticks that discovers how many are infected and by which pathogens (viruses, bacteria, protozoa, etc.) would be of great help. Such a study should then be realised in several countries (3), (4), (8), (11), (12) (16), (30). In this case, patient could be analysed more specifically (32). Further, the question arises how clinically relevant the findings may be; yet another topic of study.


The spreading of ticks

The proliferation of infected ticks depends on climatical, temporal and geographical variations.  In this sense, the living environment of the various wild animals and (already modified) immigration routes of some birds have to be considered. All of these animals are hosts for borrelias; they carry many ticks and spread them (3).  In the spreading of infected ticks by birds we may focus on birds living mainly in grass, hedges and undergrowth. They got the ticks there and then starts the transport (5), (14), (27), (28), (29). It seems that also dogs are interesting (15) and other animals (18). Furthermore, we wonder if due to climate changes, more ticks and pathogens may be able to survive in different (new) regions.  And finally, our travel behavior in this new globalised world also favours the spreading of infected ticks (means of transport, clothing, and luggage).  There are also various types of ticks that are infected with different pathogens (31). Indeed, a new borrelia strain was discovered as human-pathogenic, the borrelia miyamotoi (6), (13). It is questionable if our current test procedures for antibodies are capable of detecting this strain since neither the strain nor its antigens were known until now as necessary. It is a matter of fact that this strain was transported and distributed by birds. Who knows how many more undiscovered and human-pathogenic borrelia strains (33) and other tick-borne pathogens there are?


Mixed infections and complex survival mechanisms

Another fact appears to be important: borrelias can survive and live in various hosts such as different types of animals, e.g. many mammals, birds, ticks and even humans.  This is why the infector has to have a complex survival mechanism (escape-mechanism) (1), (2), (7), (13) i.e. creation of persistent forms, blocking or resistant against the complement-system, hiding in tissues with poor blood supply, to mention only a few.

In this contribution, we would like to focus on intra-cellular pathogens (e.g. chlamydia and ehrlichia among others) or even intra-cellular forms that some pathogens can develop (e.g. mykoplasma and rickettsia, to mention a few). Intra-cellular pathogens are often acid-resistant and fat-dissolving, just as the pathogens of tuberculosis or leprosy. These intra-cellular pathogens and their various shapes have a number of mechanisms to avoid the immune system of their host and the effects of antibiotics. They also change their appearance according to their environment. They are pleomorphic and therefore, difficult to identify for the diagnosis. The spiral form of borrelias does not fit into
an erythrozyten (red blood cells) but maybe other persistent forms of borrelias and in bigger cells.

There must to be persistent forms of borrelia “in vivo”, otherwise there would be no research to develop new strategies for treating those (2).

Many affected patients do not show single infections, but a mixture of various infections which are, in turn, affected by the mentioned environmental influences and mental stress factors.  A lack of vitamins, minerals and trace elements may exist simultaneously.  A healthy person might not need substitutions, but sick people can benefit from them (e.g. vitamin B12, H, D, zinc, etc.). The importance of vitamin- D is ever more evident (9), (10). Maybe it is important not only for the bone metabolism (24).  To reduce the risk of an overtreatment during a substitution therapy, the vitamin levels can be checked.


An important immunological organ 

Concurrently, do we know everything about the intestine where also many immune processes take place? Probiotics were added to the S3-guidelines for treating irritable bowel syndrome. This shows how important it is to study further in this field. For now, we do not have enough information to discuss (17,21). Thankfully, there are already a handful of professors who have embraced this task (1st Microbiom conference in Berchtesgaden).



Patients react differently. We know today that some patients have problems with their metabolism (absorption, processing und detoxification) also of medicine (keyword: cytochrom P450-enzymes and cascades, etc.) There are also indications of a direct influence of an infection on the cytochrome P450-system (19). We also know today that females, males (keyword: gender medicine) and children have differing metabolisms. Therefore, every therapy must be designed according to every person’s profile and specific needs.


Dosage of Doxycycline

Lastly, we would like to mention that doxycycline is often used to treat Lyme disease.  Officially, 200mg/d is recommended, but sometimes 400mg/d is applied.  It is indeed possible to measure the doxycycline levels in the patient’s blood after around 3 or 4 days of the treatment, in order to verify that the prescribed 200mg/d is sufficient to place the patient within the therapeutic range.  If those aims are not met, then a higher dose can be adapted individually.  Due to a variety of reasons, there are indeed patients who do not reach a therapeutic range when using 200mg/d of doxycycline.  In this case, the patient would be under-dosed and this would obviously not be ideal. Measuring the doxycycline levels in the blood can also help to explain or discover some “therapy failures”. Other reasons for so called “therapy failures” may also be an incorrect intake of the antibiotic, i.e. in combination with milk products.


Economical reasons for insurance companies

It is important for us to trigger discussions and hopefully apply efficient therapies to these patients all around the world. As long as there is no solution to the suffering, patients will understandably continue to search. This fact should not be underestimated – be it for economical reasons (20).  The aim should be that patients’ symptoms improve or disappear all together so that repeated visits to the doctors or hospitals resulting in multiple diagnostics and unsatisfactory therapies are avoided, as they may result in long term incapacity to work. In an recent article from the Johns Hopkins Bloomberg School of Public Health have researchers concluded, that the problems with this diesease are apparently more common than previously assumed. This costs much money, but on the other hand seems it also doesn’t make sense to continue to ignore the patients and this disease. We quote:” These patients are lost. No one really knows what to do with them. It’s a challange, but the first thing we need to do is to recognize this is a problem…” (23).


Suction period of the tick (nymph) and transmission of infectious pathogens

Fortunately there is an overview of an indenpent researcher ( after checking of scientific studies ) regarding the often emotionally debate concerning “suction period of the tick (or nymph) and the likelihood of transmission of germs (pathogens) esp. borrelia. The overview states that the transmission of borrelia could also be possible in less than 24 or 48 hours. The possibility that the pathogen could be transmitted earlier, can not be excluded. Because Borrelia were also detected in the salivary glands of ticks (and nymphs). The next question is the time for transmission of other infectious pathogenes (ehrlichia, rickettsia, bartonella, babesia.. etc.). Furthermore, the person affected often can not state an exact time specification, since when the tick (or nymph) has been sucking; if he/she even notice the tick (nymph). Perhaps this overview also helps to conduct the debate on this topic more factual (22).


We think, there are problems with tick-borne diseases generally. We are not allone with this opinion. Also the Entomological Society of America (ESA) and Dr. John Aucott from the Johns Hopkins University in the USA see these problems and ask for more research, studies and a factual discussion about it. The problems are not only in the USA.

For anyone who is interested, we have selected just a few points of discussion so that you can now research further and develop your own opinions.

It would also be a pleasure to organize constructive and factual discussions through presentations and workshops, which may lead to many more points of discussion.
