HEAVY VETTING - by Mark Purdey Further
despatches from the front line of the UK’s TB "hazard"
zone .
The current approach of the UK
veterinary establishment towards the control of TB remains rooted
to the reductionist mindset of bygone times; the uncivilised world
of blanket slaughtering and badly managed "Badgerogeddons"
that are naively aimed at achieving the impossible – to
annihilate the TB agent from the face of the earth.
Whilst livestock farms have been
subjected to these mandatory measures of mass slaughter for
several decades, the long term epidemiological pattern of TB
outbreaks would appear to have remained unaffected by these
invasive modes of control. In stark contrast to the predictions of
the most astute TB research teams, TB epidemics have continued to
rear their ugly heads with ever increasing frequency. The ‘experts’
remain privately baffled.
The problem is that their whole
policy is based upon a totalitarian science that is both derelict
and defunct of academic integrity. It fails to cater for the most
fundamental property of TB mycobacteria - that these agents are
endemic within the open environment and can therefore never be
controlled by a total wipe out mode of control. We
need to be learning how best to live alongside the TB agent, and,
more importantly, to be learning how best to boost our natural
immunity to defend ourselves against these elusive mycobacteria.
Yet, despite the obvious benefits that could be gained in building
up our understanding of the answers to these questions surrounding
our immunity against TB, no research has been commissioned in the
UK to date which looks at this crucial perspective of TB
pathogenesis.
In light of the fact that the
incidence of this disease is currently escalating out of all
proportion across the UK, it is high time that the Veterinary
establishment let go of its intransigent position on TB control,
and adopted a more open minded and inquisitive approach towards
solving the problem.
Whilst it is encouraging that the
likes of the UK Minister of Agriculture , Margaret Beckett, has
repeatedly stated " what’s the point in killing badgers if
it is not going to achieve anything in the fight against TB
", it is sad that so few other people in positions of power
seem to be listening to such a common sense approach.
Internationally recognised role
of iron in the cause of TB gets outcast by UK veterinary reviewers
as ‘unscientific’.
Last week I experienced the
Pavlovian -like response of the British Veterinarian Association
towards my plea to develop an investigation into an alternative
‘environmental/dietary’ strategy of control - as a best means
of strengthening resistance to TB infection. Their dismissal was
no doubt based upon their inability to stomach the radically
different perspective that I had presented to them. – one which
would not only require a radical about turn in their position on
the pathogenesis of TB , but in their position on the pathogenesis
of a plethora of other parasitic infections – the
ironmonger group of pathogens whose survival is totally
dependent upon the free iron supply in their host’s tissues.
If this concept is ever shown to
be correct in respect of playing a causal role in bovine TB , then
it would seriously threaten the credibility of the UK
establishment’s mass slaughter programme, as well as undermining
the vested interests and professional reputations of the powerful
egos involved in the upper echelons of the UK veterinary
establishment.
I had written a mere letter to
the editorial of the Vet Establishment’s flagship publication
which was submitted as an attempt to woo the vets away from their
unilateral policy of ‘overkill’. It presented a nutshell
version of the science surrounding the causal role of elevated
iron in the foodchain, and how this can compromise the relevant
component of our immunity, placing mammals at an
increased risk of contracting TB infection. As I had recently
written in RedFlagsdaily, the growth and survival of the TB
mycobacteria is totally dependent upon a supply of free iron
within the host’s tissues. This high iron facet
pinpoints a golden opportunity for devising a means of dealing
with this disease. If you can influence the levels of free iron
within the host, then you can control the overall outcome of the
disease; eg; The TB infection could be arrested by starving the
agent of its iron supply, which could effectively cure the
disease.
But, true to form, my letter was
rapidly subjected to a short sharp burst of "heavy
vetting", and I was not surprised to receive the classic
prudish rejection for lack of scientific rigour at
the end of the day – the stereotype response that is wielded
onto anyone who is out front about promoting fresh ideas. But I
can’t help but wonder why they do not apply the same style of
rigorous scientific scrutiny when reviewing the volumes of data
that have been published in support of the popular ‘infectious
badger’ theory of TB origins ? The whole conventional consensus
on TB science appears to have been
founded upon a series of unproven assumptions that have never
really been called to question.
It is ironic that the Vet
Establishment had rejected the science proposed in my letter, even
though it was founded upon hard experimental data of reputable
international research teams. Yet, despite referencing these
studies, they had conveniently ignored the supporting publications
and then rejected my letter on the illusory notion that my
arguments were exclusively based upon some bar-stool whims derived
from my own amateurish observations down on the farm !! In this
respect, one begins to question the real motives for their
rejection.
The UK scientific community needs
to educate itself and recognise the redoubtable role that is
played by elevated iron in the pathogenesis of TB and a myriad of
other parasitic infections. To the contrary, the merest mention of
the iron-TB association to their scientific counterparts in the
USA is met with a totally opposite reception. For example, when I
casually mentioned my own observations of increased iron on my TB
farm to a colleague at the US EPA, he instantly responded by
saying , " Iron and TB. You bet. We are cleansing land of
mycobacteria by directly spraying the open environment with iron
microcrystals. These chelate the mycobacteria, diverting the dirty
little fungal buggies into an early grave."
In the light of the repeated
failure of the badger culls to eradicate bovine TB, why on earth
aren’t the UK veterinary authorities paying serious attention to
the positive results of these foreign studies by the Americans and
Germans? Why are they resisting this alternative ray of hope?
Isn’t it time that they begin
to capitalise upon the highly successful trials where TB affected
mice were treated with the iron chelator protein, lactoferrin,
which reduced the incidence of TB by 100 fold ? Or the trials
where lime was spread on the soil of farms infested with
mycobacteria across Michigan reducing the incidence of TB
infection ten fold as a result – highly impressive results which
should be instantly taken aboard by any open minded and
intelligent authority who is working to design foolproof control
programmes to safeguard public/animal health.
Nonetheless, the following
reviewer comments comprised the mainstay of the veterinary
establishment’s response to my letter ;
"The evidence is sometimes
based on studies not directly relevant to cattle and Mycobacterium
avis, but refers to results from Mycobacterium avium subspecies
paratuberculosis (Map) and findings in mouse experiments. The inferences which are drawn from these studies and other
reported data in the letter are not rigorously supported.
For example, the observation that TB hotspots are all in
areas where iron is mined and rainfall is high is not proven
and does not explain why TB occurs elsewhere i.e. TB is not proven
to be directly correlated with soil pH or where iron is mined or
where rainfall is high. Similarly there are several
references to TB incidence changes over time which could be
explained by a host of other factors, for example changes in the
iron levels on the author's farm only proves that iron levels
have changed on the farm and is at the best weak evidence of an
associative link and at the worst insufficient proof of cause and
effect. The communication ignores the vast scientific
body of information on the epidemiology of bovine TB".
I responded to this by pointing
out that I had only submitted a letter to the
editor which was largely intended to alert veterinary
readers to this fresh perspective on TB aetiology,
and to further ask the vet practises whether I could be connected
to additional TB farmers in the hotspot zones in order to expand
my geochemical survey.
I also informed the Veterinary
establishment that their comments were too fastidious and ‘over
the top’ for a mere letter; particularly since they had implied
that I ought to be providing the full spectrum of hard evidence
for TB cause within the limited confines of my
first letter on this subject to the academic
literature!
Whilst the reviewers had
correctly raised the issue that hotspots of TB are not always
sited in areas where iron mining has existed (albeit only two
areas that I can see), their comment had failed to grasp
the bottom line prerequisite of the theory which distils
down to "elevated iron in the bovine food chain", a
problem which can arise in various contexts where iron ore
beds are not sufficiently concentrated in local bedrock
to justify the economic mining of the ore, but nonetheless, where iron is still highly concentrated in top soils for a raft
of other geochemical reasons. I had merely capitalised my argument
upon this striking correlation between the iron mining areas and
TB hotspot zones, and then utilised this as a means of providing a
generalised yardstick for demonstrating that the high iron factor
offered a plausible explanation for the distribution of TB
incidence across the UK.
There are always going to be
different environmental influences that will bring about exactly
the same end effect of elevated iron within the biosystem, which,
in turn, will influence the outcome of any TB infection in the
same way.
Anti-Lactoferrin insecticides
hammer long term immunity to TB.
For example, use of the anti-lactoferrin
insecticide wormer, Levamisole, is currently very prevalent on UK
livestock farms where it is used in various drench or systemic
pour-on wormer formulations. Although exposure to this molecule
will initially create an acceleration in the synthesis/secretion
of the immune protein ‘lactoferrin’, thereby creating an
unnatural boost to the immune defence, the long term repercussions
of such an exposure are going to be a bit like driving a car at
full throttle throughout its entire road life. You will burn the
car out, driving it to a premature grave in the scrap yard. In
this respect the long term effect of exposures to levamisole
causes a down regulation of lactoferrin secretion; due to the
disrupting effects of this chemical at its target receptors on the
T lymphocytes – eg; the receptors which mediate the secretion of
lactoferrin.
This down regulation
effect represents a well known toxicological mechanism by which a
receptor can adapt to a toxic insult, by becoming sensitised and/or reducing the rate at which receptors are replenished. The net
effect is a long term, perhaps permanent, deficiency in the
secretion of lactoferrin, which , in the context of this study,
brings about a markedly decreased level of immunity to TB
infection.
Lactoferrin is an immune protein
that is a component of exocrine secretions. It is manufactured in
the epithelia of the gut, lungs, tear ducts (as well as in the
granulocytes) where it is used as an iron chelator/antioxidant
in the armoury of immune defence against invading pathogens. In
this respect, Lactoferrin performs a pivotal role in the defence
against invading TB, where it competes against the mycobacteria
for the supply of free iron within the tissues, ultimately ‘ironing
out’ the lifeblood of the TB agent.
In this respect, the simultaneous
exposure of mammals to high iron food-chains and anti-lactoferrin
toxic agents (eg the pesticide wormer) could be sufficient to
escalate the levels of free iron in the tissues to a threshold
that is ripe for a full blown TB takeover.
Whilst I understand the
reviewer's point that the elevation of iron on my own TB affected
farm does not supply an adequate amount of hard evidence to
substantiate the theory, my letter did not actually
attempt to convey any pretentions to this effect. In the light of
the published experimental evidence surrounding high iron and TB
infection, I had merely indicated that these observations on my
own and other farms could turn out to be extremely important, and
were sufficient to warrant the expansion of a full scale
comparative geochemical investigation covering all of the main TB
foci regions across the UK.
I feel that the higher impact
mainstream journals ought to be publishing the more plausible
speculative creative leaps in scientific thinking, rather than
rejecting them outright. For the history of science has repeatedly
shown that the majority of advancement within academia has
invariably stemmed from intuitive sparks of speculative insight
– usually originating from the layperson. Yet whenever these so
called heretic ideas have been successfully suppressed by the
mainstream in the past - due to peer prejudice, commercial or
political pressures, etc – the healthy evolution of
scientific knowledge usually always suffers a severe set
back as a result.
Consider the negative
outcome for medicine, if Jenner's original
observations on the immunisation of milkmaids against small
pox had been outright rejected at the start? For his initial
observations were based upon a group of milk maidens who were
working with cowpox infected cattle in a cowshed on a single
farm in Gloucestershire. The, milkmaids had unwittingly
immunised themselves against small pox as a result. If Jenner’s
hypothesis had been blocked on grounds that his
initial observations were only sourced from a single farm (and therefore could not be shown to hold true for every milk
maid operating across the UK) then his important discovery may
never have been permitted to see the light of day.
Likewise, where would we be in
our understanding of the role that vitamin C performs in the
prevention of scurvy, had the solo observations of the
"limey sailor" been ignored .
I also take issue with the
veterinarian establishment where they state that the
arguments in my letter were not based upon rigorous scientific
studies. Whilst my own analytical studies to date clearly provide a limited amount of hard
evidence, I feel that their comments are misappropriated in
respect of the true validity and relevance of the experimental
data that was referenced in my letter.
In relation to the veterinary
critique written above, I should point out that my letter had
clearly indicated that these experiments had involved mice rather
than bovines, and mycobacteria paratuberculosis rather
than mycobacteria tuberculosis. Furthermore, I cannot see how
the differences between the species/strains involved in these
experiments should weaken the overall relevance of these trials to
the context of bovine TB outbreaks in the UK. In fact, It is
counterproductive to be ignoring this work.
My letter had also pointed out
that all strains of mycobacteria require a source
of iron to manifest their pathogenicity, irrespective of whether
the paratuberculosis or tuberculosis strain is involved .
I was particularly annoyed over
their failure to recognise the potential relevance of
the positive study in which the number of TB pathogens in
infected mice had been reduced 100 fold after treatment with the
iron chelator lactoferrin. The Vet Establishment had rejected this
valuable research on the basis that the work relates to TB in mice
and not TB in bovines.
Aren’t the reviewers aware of
the universal use of misfortunate lab mice in millions of drug
licensing trials where animal reaction to pharmaceutical exposure
is exploited as a best means of assessing the potential health
effects of those chemicals upon human beings. Furthermore,
the entire global establishment has heralded the
results of the mice studies carried out by Dr Moira Bruce at
Edinburgh, as a plausible means of proving the causal connection
between human consumption of BSE affected cow tissues and the
development of variant CJD in humans - presumably because
Moira Bruce’s conclusions were in support of the
prevailing 'politically correct' theory at that time!
The Pavlovian-like rejection of
outsider scientists .
Once again, it seems that the
work of outsider scientists has to rank at the top end of the
scale; where the quality of their protocols and presentation of
their data has to be as white as white can be. But it is a totally
different story for those who operate from within the inner circle
of incestuous expertise. They can get away with any old hotch
potched piece of epidemiological data as long as it supports
the establishment line.
One good example of pathological
prejudice against ‘outsiders’ was enacted via the peer review
system operated by "The Veterinary Record" journal. One
of my own papers on TSEs was outright rejected in 2004 after being
subjected to the usual stereotype accolade of "lack of
scientific rigour", despite having presented some ground
breaking data from the analyses of 200 soil and antler samples
that I had collected across chronic wasting disease cluster zones
in the USA/Canada. Ironically, a few weeks later, a hopelessly
unscientific paper aimed at discrediting my data by Chihota et al
( from the prestigious Compton Labs in the UK) was published by
the Vet Record despite the admission by the author that they could
not afford to carry out any analyses !! ...... "
to carry out blood testing and analysis on the necessary scale
would have been prohibitively expensive. Instead, we sent a
questionnaire survey to farmers asking them what minerals were
deficient in their area and compared this with data from the
National Soil Inventory".
But the Chihota paper had
completely misrepresented the bottom line prerequisite of my
published research into TSEs, which decrees that the loss of
copper binding at the prion protein is a primary prerequisite of
TSE pathogenesis. This can be achieved via several routes; copper
deficiency in the environment, copper lock up in the biosystem due
to contamination with copper chelating chemicals, or displacement
of copper binding at PrP due to competitive binding at the protein
ligands by substitute metals such as silver, etc, etc.
Chihota et al had only considered
one of the many possible routes for achieving the all important
end point that induces scrapie; so when they had failed to stand
up their select criteria (eg environmental copper deficiency) in
all of the scrapie clusters that they had studied , they
arrogantly pronounced the theory as totally flawed!
Vets in a spin to promote their
propaganda for continued slaughter
Back on the TB battle front, the
British veterinary establishment’s Pavlovian-like rejection of
the widely recognised ‘high iron’ perspective of TB
pathogenesis, betrays their determination to remain wedded to the
deadlock of the current slaughter strategy – a universally
adopted policy of control that is rigidly upheld across the more
affluent sectors of the developed world. Furthermore, these
uncivilised strategies of mass slaughter are by no means exclusive
to the control of TB. They have been repeatedly implemented over
the last century to suppress the outbreaks of a whole raft of
supposedly ‘infectious’ diseases; for example, the pseudo
infectious TSEs (mad cow group of diseases).
In one respect, it is both sad
and ironic to witness such a mindset for the mass murder of
animals amongst those who are trained in the skills of saving
animal life. Why are they so eager to close the door on any
serious alternative that offers a more plausible and lucrative
strategy for dealing with this problem? Surely, it is the
foremost duty of any responsible authority to try to provide a
more civilised option of disease control before resorting to the
final, farcical solution of blanket slaughter?
The Badger-Bashers.
But the infectious myth
surrounding TB controls has been transmitted across the entire
rural community – to the extent that various vigilante groups
have been taking the law into their own hands and illegally
gassing the badgers into oblivion within the TB areas.
I was appalled to learn that one
of these insidious cyanide sessions had taken place on my own
farm, down at the most vibrant badger sett in our valley. The
Local badger community had become the full scale target of one of
these moonlight gas attacks, where the intruders were acting so
complacently, that they had forgotten to take their empty gas
bottles away. I had found the steely cylinders not far from the
entrances to the sett - slumped incongruously across a clump of
bluebells .
If only these insensitive idiots
had been aware that the bluebell tubers provide the dietary source
of concentrated iron that actually enables a TB infection to take
a hold in the badgers.
In this respect, these badger
bashers would have carried out a much more effective job
at cleansing the animal kingdom of TB, if they had uprooted the
bluebell tubers and left the poor old badgers well alone
Feed trials ‘ iron out’ the
TB from some of my cows ?
But perhaps the most positive
piece of news from behind the iron curtain of the TB hazard zone
involves the results of some pilot studies that I had conducted on
a batch of "inconclusive" TB reactor cows residing on my
farm.
I had intensively fed these cows
with a mineral-protein formulation that was designed to chelate
the iron, as well as impair the uptake of iron into the
cow. I was running this pilot experiment with the aim
of starving the TB parasite to death, The results
so far have been encouraging;
With a total of
six inconclusive animals residing on my farm, five were
milking cows who had been fed the formulation during each
milking over a one month period. At the TB test last
week, the government vets decreed that four out of the five
treated animals had recovered and reverted to TB-free status,
whilst the remaining one had retained her TB ‘inconclusive’
status. The sixth TB inconclusive animal - who was a
beef steer and never fed the formulation - was found to have
progressed to full ‘TB reactor’ status and is committed to
slaughter.
Whilst the positive results of
this pilot study are hardly significant in scientific terms –
because of the small numbers of animals involved - they do however
indicate the possibility that all bar one of these inconclusive
cattle are no longer reacting to the TB test because they had been
treated with a feed that was designed to chelate and compete for
the iron supply upon which the TB agent survives. In this respect,
it is imperative that this investigation is advanced to the next
stage, and tested upon a much larger group of animals.
Sadly, independent researchers
such as myself, who invariably have to spend their own money to
kick off pioneer investigations that go against the Establishment
grain, are all too frequently ignored by the mainstream -
irrespective of the true value of the data that they can produce
at the end of the day.
Just as the UK veterinary
association have subjected my letter to their classic ‘knee-jerk’
rejection, the infectious myth surrounding TB is gathering
momentum and spreading to all quarters of the UK Establishment.
Today, my farm and family find ourselves subjected to a steady
derisory trickle of ridicule and dirty tricks, all for the crime
of trying to get to the root cause of disease, so that the
needless and reckless slaughter of mammalian life can be
prevented. We are sadly living in retrograde times.
