Abstract
We determined the fecal carriage rate of serotype K1
Klebsiella pneumoniae in healthy Koreans and studied their
genetic relationship with liver abscess isolates. We compared
the carriage according to the country of residence. The stool
specimens were collected through health promotion programs
in Korea. K. pneumoniae strains were selected and tested for
K1 by PCR. Serotype K1 isolates were characterized by
multilocus sequence typing and pulsed field gel electrophoresis.
A total of 248K. pneumoniae isolates were obtained from
1,174 Koreans. Serotype K1 was identified in 57 (4.9%), of
which 54 (94.7%) were ST 23 and were closely related to the
liver abscess isolates. Participants aged >25 years showed a
higher fecal carriage rate than those ≤ 25 (P=0.007). The
proportion of serotype K1 out of K. pneumoniae isolates in
foreigners of Korean ethnicity who had lived in other
countries was lower compared with those who had lived in
Korea (5.6% vs 24.1%, P=0.024). A substantial proportion of
Koreans >25 years carries serotype K1K. pneumoniae ST23
strains, which are closely related to liver abscess isolates.
Differences in carriage rates by country of residence suggests
that environmental factors might play an important role in the
carriage of this strain.
