Aeromonas hydrophila is an important bacterial pathogen which causes the hemorrhagic septicemia in fishes, amphibians and humans. Genetic relationships of diverse isolates of A. hydrophila were recovered from fish and water sources. These isolates were investigated by flanked region of 16S and 23S Ribosomal DNA (rDNA) internal transcribed spacer (ITS). Here we analyzed polymorphism of PCR-amplified 16S-23S rDNA ITS and their revealed band pattern consisting of one to four DNA fragments. The fragment size ranged from 500 to 1000 bp. The DNA band patterns revealed a considerable genetic diversity in interaspecies. The 750 bp size of band was common in all isolates of A. hydrophila except one Isolates AH21. The tRNA-Glu sequences were identified from 750 bp size of ITS region that could be used as strain level potential genotypic markers.

Disease and sufferings lead religious persons nearer to almighty in search of mercy. Not much is known about how to design and disseminate programs of spiritual exercises and spiritual indicators for persons suffering with some disease (sufferers). Research is required to advance the understanding of prioritized internal and external indicators responsible for spiritual awakening among these sufferers. In this paper, an attempt is made to compute OFDP (overall futuristic decision priority) weights to generate spiritual scenarios for spiritual awakening by using MCFDM (multi-criteria futuristic decision-making) methodology. The generated prioritized spiritual scenarios responsible for spiritual awakening among sufferers were then used to assess the effect of some kind of disease (physical problem, suffering, disorder, etc.) on strengthening their religious faith and defining their optimal spiritual trajectories towards ultimate reality. In this research work, a two-phased DRFI (disease-religious faith-interaction) experiment is also designed and developed. The results derived from Phase-I pilot research study based on prioritized spiritual scenarios on 20 male and female sufferers are also presented.
