Study results show K12 probiotic helps prevent rheumatic fever
As the Government launches a new rheumatic fever awareness campaign this week, results from a recent European clinical
trial show that the daily use of a Kiwi-developed oral probiotic, BLIS K12
TM, is associated with a significant and ongoing reduction in throat infections and other streptococcal diseases among
Rheumatic fever is a complication of a throat infection caused by Streptococcus pyogenes bacteria. Left untreated, the bacteria can cause serious health problems, including heart failure or heart valve
damage. Children and young people from Pacific and Māori communities are the most vulnerable.
The Government’s $65 million programme to reduce the number of new rheumatic fever cases by two-thirds by June 2017 is
falling behind its target and the goal might not be reached till 2019 or later.
BLIS K12 or Streptococcus salivarius K12 is the world’s first probiotic for the mouth and throat and is hostile to the growth ofStreptococcus pyogenes, the most important bacterial cause of throat infections in humans.
“BLIS K12 populates the mouth and throat with a beneficial strain of Streptococcus salivarius which not only crowds out the bad bacteria, but produces antimicrobial peptides that add a level of protection against
them coming back. As this latest study shows, it is effective in preventing streptococcal throat infections. We believe
this probiotic should be considered, alongside other strategies, as one way of reducing streptococcal sore throats and
the possible complications such as rheumatic fever in our communities,” explains BLIS Technologies chief technology
officer, Dr John Hale.
The study, published in the Drug Healthcare and Patient Safety Journal by a team from Velleja Research led by Dr Francesco Di Pierro in Italy, ran an observational study of 124 schoolchildren
in 2014. The treated group of 48 children with a recent history of recurrent pharyngeal streptococcal disease (sore
throats) received a daily oral dose of BLIS K12 for 90 days. A control group of 76 children with no recent history of
sore throats who were not given BLIS K12 was also monitored.
During the trial the incidence of throat infections (streptococcal pharyngo-tonsillitis) was reduced by 90 percent in
the treated group compared to the previous (pre-treatment) year and was lower than the untreated low risk control group.
The authors reported that the results agree with previous findings that BLIS K12 offers benefits to children in reducing
streptococcal disease along with some other throat and ear infections.2
BLIS K12 is present in ThroatGuard Lozenges and ToddlerProtect powder, both of which are available over-the-counter from
pharmacies and online at www.blis.co.nz

About BLIS Technologies
Blis Technologies Limited was formed to commercialise advanced probiotic strains that work outside the gut. Professor
John Tagg of the Microbiology and Immunology Department at the University of Otago gathered and extensively catalogued a
collection of more than 2000 of these bacteria over a period of more than 30 years. Blis Technologies acquired the
rights to this unique collection of bacteria from the University of Otago and in July 2001, the company was listed on
the New Zealand Stock Exchange. In the time since its listing, the company has developed consumer products for throat
health, halitosis (bad breath), immune support and teeth and gum health.
