| Summary: | Leptospirosis caused by infection with pathogenic leptospires, which is the most prevalent zoonotic disease in
the world. The outer membrane proteins (OMPs) of pathogenic leptospires such as LipL41 play a crucial role
in pathogenesis of this disease. Therefore a major challenge to develop an effective vaccine against
leptospirosis is application of basic research on the OMPs of leptospires to improve vaccine development. The
aim of this study was cloning and analyzing of the lipL41 gene from vaccinal serovars of leptospires in Iran, in
order to identify genetic conservation of this gene. Three vaccinal serovars of Leptospira were used in this
study. The lipL41 gene of these serovars were amplified and cloned in the pTZ57R/T vector. The recombinant
clones were confirmed by colony-PCR and sequencing. The sequenced genes were analyzed for their
homology between them and other submitted sequences in Genbank database using the BLAST and
MegAlign program. PCR amplification of the lipL41 gene resulted in the 1065 bp gene product in vaccinal
serovars tested. In our study, nucleotide sequencing results showed high similarity (>94%) within the
leptospiral vaccinal serovars. The genetic conservation of the lipL41gene among different serovars of Leptospira
indicated the capacity of utilization of this gene for development of recombinant vaccine against leptospirosis. |
