摘要： The present invention relates to the field of immunogenic compositions and vaccines, their manufacture, host cells which can be used in their manufacture and the use of such immunogenic compositions and vaccines in medicine. More particularly, it relates to Klebsiella pneumoniae O-antigens, conjugates comprising a K. pneumoniae O-antigen, host cells suitable for their production and immunogenic compositions or vaccines containing at least one Klebsiella pneumoniae O-antigen.

摘要： A process for engineering a host cell comprising the steps of a) integrating a first polynucleotide cassette including a first selection marker flanked by a first pair of recombination sites; b) removing the first selection marker by the action of a recombinase which recognises the first pair of recombination sites; c) integrating a second polynucleotide cassette including a second selection marker flanked by a second pair of recombination sites; and d) removing the second selection marker by the action of a recombinase which recognises the second pair of recombination sites. The first and second pairs of recombination sites have identical nucleic acid sequences within each pair, sharing 90-98% nucleic acid sequence identity. Also disclosed is a host cell genome polynucleotide comprising two recombinantly engineered regions, each adjacent to a single recombination site sharing 90-98% identity with each other and any additional recombination sites present in the host cell genome polynucleotide.

Also disclosed is a host cell genome polynucleotide comprising a first recombinantly engineered region and a second recombinantly engineered region, wherein a first single recombination site is adjacent to the first recombinantly engineered region, and a second single recombination site is adjacent to the second recombinantly engineered region.
