Protection against a chlamydial respiratory challenge by a chimeric vaccine formulated with the Chlamydia muridarum major outer membrane protein variable domains using the Neisseria lactamica porin B as a scaffold

The major outer membrane protein of Chlamydia psittaci functions as a porin-like ion channel.

The major outer membrane protein (MOMP) of Chlamydia species shares several biochemical properties with classical porin proteins. Secondary structure analysis by circular dichroism now reveals that MOMP purified from Chlamydia psittaci has a predominantly beta-sheet content (62%), which is also typical of bacterial porins. Can MOMP form functional ion channels? To directly test the "porin chann...

Partial protection against chlamydial reproductive tract infection by a recombinant major outer membrane protein/CpG/cholera toxin intranasal vaccine in the guinea pig Chlamydia caviae model.

Chlamydia trachomatis is a major cause of sexually transmitted diseases worldwide. There is currently no vaccine to protect against chlamydial infection of the female reproductive tract. Vaccine development has predominantly utilised the murine model; however, infection of female guinea pigs with Chlamydia caviae more closely resembles chlamydial infection of the human female reproductive tract...

A chlamydial major outer membrane protein extract as a trachoma vaccine candidate.

PURPOSE As shown in infected humans and in animal models of chlamydial infection, the major outer membrane protein (MOMP) of Chlamydia trachomatis is immunogenically potent. The purpose of this investigation was to test in the cynomolgus monkey model of trachoma a new extract of MOMP as a candidate vaccine against ocular chlamydial infection. METHOD The nonionic detergent octyl-beta-D glucopy...

Chlamydia muridarum Challenge with Protection Elicited against a Vaginal Amphipols May Account for the Very Robust Epitopes in a Vaccine Formulated with Increased Immunoaccessibility of MOMP

Immunization with an acellular vaccine consisting of the outer membrane complex of Chlamydia trachomatis induces protection against a genital challenge.

The ability to induce protection against a genital challenge was studied in BALB/c female mice with three Chlamydia trachomatis mouse pneumonitis (MoPn) major outer membrane protein (MOMP) preparations as well as an acellular vaccine consisting of the chlamydial outer membrane complex (COMC). The MOMP preparations were extracted with three different types of detergents, sodium dodecyl sulfate (...
