A Study on IFN-γ and IL-10 Gene Expression Changes in Gallus gallus Embryo Infected with Pseudomonas aeruginosa and Its Possible Restoration by Bakreshwar Hot Spring Water

Abstract

Bakreswar hot spring is a naturally occurring hot spring located at Birbhum district in West Bengal, India. The surface temperatures of the hot springs varies between 35°C to 66°C. The water of hot spring is alkaline with pH 9 and has curative properties. Pseudomonas aeruginosa is an important pathogen causing hospital acquired infections and in this study we used multi-drug resistance (MDR) isolate. The motive of the study is to compare the IL-10 and IFN-γ gene expression changes in Gallus gallus domesticus embryo infected with Pseudomonas aeruginosa by using the Bakreswar hot spring water.The curative properties of the hot spring water collected from Agnikund (65°C) was studied on 14thdays old chick eggs infected with Pseudomonas aeruginosa. After harvesting and allantoic fluid collection, RNA extraction was done and cDNA synthesis and RT-PCR were performed. After infection of the chick embryo with MDR Pseudomonas aeruginosa, both IL-10 and IFN-Ƴ gene expressions were increased, but in the curative sets those were challenged with Bakreswar hot spring water IL-10 and IFN- γ both gene expressions were decreased. From this study we may conclude that hot spring water of Bakreswar has antimicrobial activity against Pseudomonas aeruginosa due to which it decreses the cytokine gene expressions.
