BACKGROUND: Urinary tract infections (UTIs) are among the most prevalent
microbial diseases and their financial burden on society is substantial. The
continuing increase of antibiotic resistance worldwide is alarming so that
well-tolerated, highly effective therapeutic alternatives are urgently needed.
OBJECTIVE: To investigate the effect of bacteriophages on Escherichia coli and
Klebsiella pneumoniae strains isolated from the urine of patients suffering from
UTIs. MATERIAL AND METHODS: Forty-one E. coli and 9 K. pneumoniae strains,
isolated from the urine of patients suffering from UTIs, were tested in vitro for
their susceptibility toward bacteriophages. The bacteriophages originated from
either commercially available bacteriophage cocktails registered in Georgia or
from the bacteriophage collection of the George Eliava Institute of
Bacteriophage, Microbiology and Virology. In vitro screening of bacterial strains
was performed by use of the spot-test method. The experiments were implemented
three times by different groups of scientists. RESULTS: The lytic activity of the
commercial bacteriophage cocktails on the 41 E. coli strains varied between 66%
(Pyo bacteriophage) and 93% (Enko bacteriophage). After bacteriophage adaptation
of the Pyo bacteriophage cocktail, its lytic activity was increased from 66 to
93% and only one E. coli strain remained resistant. One bacteriophage of the
Eliava collection could lyse all 9 K. pneumoniae strains. CONCLUSIONS: Based on
the high lytic activity and the potential of resistance optimization by direct
adaption of bacteriophages as reported in this study, and in view of the
continuing increase of antibiotic resistance worldwide, bacteriophage therapy is
a promising treatment option for UTIs highly warranting randomized controlled
trials.
