IL17 Responses in Rabbits Primed with E. coli-P. aeruginosa Bacterin Combinations

Abstract

This chapter aimed for the developing prototype E. coli - P. aeruginosa heat killed bacterin balanced and unbalanced bacterin combinations, as well as monotypic E. coli and single P. aeruginosa bacterins. Microbial vaccines specific immune primed to different mammalian immune systems shown an array of IL17 responses as; increase, decrease, or variable from controls. The evolution of genetic engineering techniques has enabled the construction of recombinant microorganisms capable of expressing heterologous proteins in different cellular compartments, improving their antigenic potential for the production of vaccines against viruses, bacteria, and parasites. From a series of patients with urinary tract infections, a uropathic gram negative isolates were purified and identified by VITEK identification system as E. coli and P. aeruginosa. At the end of the specific immune-priming protocols, rabbits were bleed and sera were saved in 0.5 ml aliquots at -18C till testing due time. IL17 ELIZA assay was done on the test and control sera. In comparison to double balanced, unbalanced, and control bacterin combinations, a single strength balanced combined bacterin combination increased the mean IL17 concentrations. Inhibition in IL17 concentration means was observed in the other combinations compared to the control. The immunological interference correlated like follows: one bacterium amplifies the other, while another attenuates the other. Enhancement of IL17 response single strength combination might be a promise for the efficacy of such combination in regulation and protection against natural or experimental infectious challenges.
