Klebsiella pneumoniae U25 is a multidrug resistant strain isolated
from a tertiary care hospital in Chennai, India. Here, we report the complete
annotated genome sequence of strain U25 obtained using PacBio RSII. This is the first
report of the whole genome of K. pneumoniaespecies from Chennai. It
consists of a single circular chromosome of size 5,491,870-bp and two plasmids of
size 211,813 and 172,619-bp. The genes associated with multidrug resistance were
identified. The chromosome of U25 was found to have eight antibiotic resistant genes
[blaOXA-1,blaSHV-28,
aac(6’)1b-cr,catB3, oqxAB,
dfrA1]. The plasmid pMGRU25-001 was found to have only one
resistant gene (catA1) while plasmid pMGRU25-002 had 20 resistant
genes [strAB, aadA1,aac(6’)-Ib,
aac(3)-IId,sul1,2,
blaTEM-1A,1B,blaOXA-9,
blaCTX-M-15,blaSHV-11, cmlA1,
erm(B),mph(A)]. A mutation in the porin OmpK36
was identified which is likely to be associated with the intermediate resistance to
carbapenems in the absence of carbapenemase genes. U25 is one of the few K.
pneumoniaestrains to harbour clustered regularly interspaced short
palindromic repeats (CRISPR) systems. Two CRISPR arrays corresponding to Cas3 family
helicase were identified in the genome. When compared to K.
pneumoniaeNTUHK2044, a transposase gene InsH of IS5-13
was found inserted.
