Expression and characterization of recombinant leptospiral outer membrane protein LipL32 from Leptospira interrogans serovar autumnalis.
Leptospira interrogans serovar autumnalis, a causative agent of leptospirosis in Thailand, was isolated from a patient for DNA extraction and amplification of LipL32 gene by polymerase chain reaction (PCR). The 782 bp PCR product was obtained, which was inserted into pAE plasmid with polyhistidine (His6 tag) to construct pAE-LipL32. This recombinant plasmid was transfected into E. coli BL21 (DE...
متن کاملIdentification of immunodominant linear B-cell epitopes within the major outer membrane protein of Chlamydia trachomatis.
Chlamydia trachomatis is one of the most prevalent sexually transmitted pathogens. Chlamydial major outer membrane protein (MOMP) can induce strong cellular and humoral immune responses in murine models and has been regarded as a potential vaccine candidate. In this report, the amino acid sequence of MOMP was analyzed using computer-assisted techniques to scan B-cell epitopes, and three possibl...
متن کاملVaccination with leptospiral outer membrane lipoprotein LipL32 reduces kidney invasion of Leptospira interrogans serovar canicola in hamsters.
The Leptospira interrogans vaccines currently available are serovar specific and require regular booster immunizations to maintain protection of the host. In addition, a hamster challenge batch potency test is necessary to evaluate these vaccines prior to market release, requiring the use of a large number of animals, which is ethically and financially undesirable. Our previous work showed that...
متن کاملPost-translational Modification of LipL32 during Leptospira interrogans Infection
BACKGROUND Leptospirosis, a re-emerging disease of global importance caused by pathogenic Leptospira spp., is considered the world's most widespread zoonotic disease. Rats serve as asymptomatic carriers of pathogenic Leptospira and are critical for disease spread. In such reservoir hosts, leptospires colonize the kidney, are shed in the urine, persist in fresh water and gain access to a new mam...
متن کاملTherapeutic epitopes of Leptospira LipL32 protein and their characteristics.
Two LipL32-specific mouse monoclonal antibodies (mAbLPF1 and mAbLPF2) which neutralized Leptospira-mediated hemolysis in vitro and rescued hamsters from lethal Leptospira infection were produced. In this communication, locations and characteristics of the protective epitopes of the mAbs were studied by using a truncated LipL32 recombinant protein based-immunoassay and phage consensus mimotope i...
