Abstract

ABSTRACT

        Background and Objective: In this study, we compared the susceptibility of Salmonella typhimurium phoP mutant and its parent to stress conditions that the pathogen may encounter in a host.

        Methods: For this purpose, we used the phoP deletion mutant constructed in our previous study. In order to test the in vitro susceptibility of the mutant to stress factors, the effect of acidic pH, heat, bile salts and polymyxin on growth of the mutant was examined. Then, minimum inhibitory concentration and minimum bactericidal concentration of bile salts and polymyxin were determined. Salmonella typhimurium 14028 was used as the parent strain.

         Results: The mutant was highly susceptible to bile salts and polymyxin in comparison with the parent strain, but no difference was observed in their susceptibility to acid and heat.

          Conclusion: This study confirms the role of the phoP in resistance of Salmonella to polymyxin and bile salts. Mutation in the phoP leads to susceptibility of the mutant to bile and cationic antimicrobial peptides.

         Keywords: In vitro, Mutant, Salmonella typhimurium, Disease Susceptibility.

Abstract
Introduction: COVID 19 pandemic caused by SARS-COV2 virus has taken a toll all over the world. The susceptibility of various diseases like Helicobacter Pylori, Hepatitis B virus and Norwalk Virus and even SARS Corona Virus 1 have been associated with ABO blood groups. However, very limited data is available regarding the COVID 19 susceptibility and ABO blood groups. Methods: In the present report we investigated 500 admitted patients who were RTPCR positive for corona virus. Significant Tests were applied to study association of blood groups vis a vis disease severity, ICU admissions and assisted ventilation. Results:  We found out that Type A blood group is more susceptible to severe COVID 19 infection, even though maximum patients were of type B blood group. We also found that type A blood group needed more ICU admission and assisted ventilation then non type A groups and difference was statistically significant. Conclusion: Patients with type A blood group COVID 19 patients with type A blood group might require more vigilant surveillance and aggressive treatment measures. Further studies are required to validate the disease susceptibility.
