Is microscopy
dangerous or immoral?
You might get this impression with respect to the criticism professor Morten
Laane got last year. Norway’s leading expert on microscopy (b. 1940) was, in the
media, even accused of presenting artifacts and trash science when revealing
his research done together with the zoologist Ivar Mysterud in their search for
answers to what is causing chronic disease in humans after tick bites.

Story at-a-glance
✓ The retired biologists Morten Laane and Ivar Mysterud were subject
to heated debates in the Norwegian media last year due to their use of
microscopy as a tool to examine blood from people who have become
chronically ill following tick bites.
✓ In this interview Morten Laane deepens central aspects around
microscopy. In the previous interview Ivar Mysterud presents his view of
the criticism.
✓ The microscopy methods used have deep historical roots, however,
are now considerably improved for detailed observations and digital
recordings of bacteria and parasites which reside in red blood cells.
✓ Everyone can easily look through a microscope; however, it demands
great and time-consuming work and experience to become decent at
microscopy. An understanding of the mechanisms of the microscope is
required, and the person executing the microscopy needs to possess
interdisciplinary experience when interpreting what is observed in the
specimens.
✓ Studying the presence of microorganisms in blood is thus demanding.
✓ In comparison to other test methods, microscopy shows the immediate situation in a specimen.
✓ Laane rejects the criticism that they have not observed real spirochetes (spiral-formed bacteria) and co-infections in the blood of patients
sick after tick bites. The structures are not protein fragments from blood
cells during decomposition, by some called pseudo spirochetes. He
has techniques to distinguish beyond any doubt the difference between
spirochetes and pseudo spirochetes and has filmed spirochetes that
actively move in and out of red blood cells. Laane also finds it incorrect
to call anything pseudo spirochetes and he challenges the argument
from opponents suggesting that general basic concepts of blood microbiology may be wrong.
✓ Laane is equally strong in his persuasion that microscopy is an invaluable tool for studying blood of people who have become chronically
sick after tick bites. The results from a new, ongoing research project
might indeed become useful for this group of patients.

In spite of professional criticism, Laane
is equally strong in his persuasion that
microscopy is an invaluable tool for studying blood of chronically sick people. This
can provide a good indication of what is
really wrong with them.
It seems like microscopy as a method is
controversial in the eyes of some professionals. What is the reason for this?
– Lack of knowledge and loss of microbiological knowledge, Laane answers.
He explains that the first bacteria were
discovered in the 17th century by Antonie
van Leeuwenhoek (1632–1723). Among
lots of studies a “tooth spirochete” from a
biofilm in the oral cavity is described and
illustrated in his book Archana naturae
detecta, published in 1695. It is a collection of scientific letters to the Royal Society
of London. Laane emphasizes that this
meant approval at that time. – Physicians
who make statements about microscopy
should, at least, be able to repeat what van
Leeuwenhoek did, even if it is intricate,
Laane thinks.
The method you have used to identify the
presence of potential Borrelia spirochetes
is often presented as new. Why do you
disagree with this?
– Nothing is basically new. The methods
we are currently using are based on
insights in microscopy that gradually have
been developed throughout history, Laane
answers. – However, the techniques that

for a long time have been used for
observing spirochetes have now been
greatly improved. It is important to
create conditions with reduced oxygen
levels in the living blood specimens.
The reduction of oxygen content seems
to stimulate inactive, hidden bacteria
and parasites to move out of the red
blood cells and become more easily
observed and imaged, the researcher
continues.1
Is it easy to do microscopy?
– Everyone can easily look through a
microscope. However, it demands a
great extent of work and long experience to become good. Only experience
will give a good understanding of what
can be observed. – Thus it is time consuming, Laane points out.
– Modern DNA analyses usually work
in a way that the specimen is sent to a
special laboratory and the sequences are
then returned. Thereafter you search
on a computer. This is to a great extent
less time consuming than working with
a microscope and becoming good at it.
Perhaps this is partly the reason why
microscopy is not widespread and is
less popular today, Laane wonders.
You have for decades lectured students
in the use of the microscope. What is
the main emphasis you have exhorted
them with when they use the microscope?
– A person has to understand how
the microscope works, an essential
“quality” in order to be able to use
it well. Practice and experience in
interpreting what you observe in
specimens is crucial, and frequent
use is necessary to become good,
Laane answers. – It is a pity that
education in traditional microscopy
generally is reduced both in schools,
universities and colleges. Highly
specialized, so-called confocal microscopes are popular and can be linked
to advanced molecular techniques;
however, you lose a great deal which
could have been detected by much
simpler microscopes. We need both

Laane says.
Demanding to study blood
The eager researcher explains that it
is demanding to study blood. Blood
is namely a very complex substance.
– First of all around 40 possible cell
types exist in blood, all of which you

Society
need to be able to identify. For instance,
if you want to detect a bacterium or
parasite, you need to know something
about “the background conditions”
in blood, he emphasizes. Laane tells
that one needs insight into what fibrin
looks like, i.e. thin threads of protein
in the blood, and changes in cell types
and other structures in blood that can
vary both under preparation and with
disease.
He further states that for optic reasons
red blood cells normally hide both
bacteria and parasites. They are small,
biconcave lenses, causing optic disturbances. Such problems are solved
through a careful swelling so that they
become more flat.
– The Borrelia bacteria at steep angles
may become so long and thin that it is
difficult to see them in a light microscope. By using another technique –
dark field microscopy – you send the
light in from the side, and bacteria and
other structures lighten up against a
black background. This complements
what you see through a light microscope
where the light is sent from below.
The syphilis bacteria and Borrelia bacteria have morphological similarities
of significance for simple detection. In
this textbook effective and very simple
microscopic techniques are described
which later have become more or less
abandoned in medicine. Laane’s father
used these methods as a military field
physician (officer) in the Norwegian
army during the Second World War,
and later when he resumed his private
practice in Tønsberg. At that time Tønsberg was a significant seaport. Many
needed to be tested because sailors
brought contagion from abroad. In
those days microscopic survey methods
were common and accepted amongst
Norwegian physicians. Laane’s interest
for microscopy arose when he observed
this at his father’s office in 1947, i.e.
when he was around seven years old.
At that time he also discovered Bruusgaard’s textbook.
This background has since led to

professional career, as a biological

recognized as a highly respected expert
in microscopy. Laane is also the author

Laane has never doubted their observations in the blood of chronically sick
patients after tick bites: – It is without
doubt spirochetes, and they are probably Borrelia bacteria since the patients
have been bitten by ticks. However, the

very complex processes linked to red
blood cells. Some “pseudo spirochetes”
emerge because the bacteria have two
membranes, and are able to shed the
outer membrane. In the microscope
this will be observed as a thin residual,
and it often has chromosomes inside,
detectable with specific stains. Thus,
this has nothing to do with protein fragments from red blood cells, however,
it involves parts of a spirochete and
sometimes also the red blood cells, the
experienced researcher explains.
– In a microscope you can thus observe
products from the cell membranes of
the red blood cells. They often contain
some DNA from bacteria that were
inside the blood cell. Such products
conduct so-called Brownian motions.
It is possible to film what you observe
in the microscope and filtrate Brownian motions. On the film you will then
