The Role of Dietary Proteins During Infection with Covid-19 and the Effect of Infection on the Balance of Oral Microbiota in Different Regions of Iraq

Abstract

Abstract This study was conducted in the laboratories of the Department of Life Sciences - College of Sciences - Tikrit University and laboratories of the Department of Food Sciences - College of Agriculture - University of Anbar and public health laboratories - Anbar for the period from December 2021 to February 2022 AD. The study included 150 people from three Iraqi governorates (Baghdad, Anbar, and Erbil). (30 infected people and 20 healthy people from each governorate, with ages ranging from 18-80 years, randomly, men and women. The results of the blood biochemical parameters values when infected with the SARS-COV2 virus showed a significant decrease at the probability level (p<0.05) in the concentration of albumin in the group of patients who were in quarantine and using artificial respiration, compared with the group of patients outside the quarantine and the healthy group from the mentioned governorates. The concentrations are 26.3, 30.4, and 34.7 (g/l). It also caused a significant decrease in the total protein and albumin concentration in all patients compared to the healthy subjects. In contrast, globulin concentration decreased slightly to be close to its value in the healthy group. Cultural, phenotypic, biochemical, and confirmatory tests through the Vitec2 compact diagnostic system showed that oral bacterial isolates purified from patients in the three provinces were Gram-positive Staphylococcus and Enterococcus versus four Gram-negative genera: Sphingomonas, Rhizobium, Aeromonas, and Ochrobactrum, compared with isolates purified from healthy subjects, which belongs to four genera of Gram-positive Staphylococcus, Enterococcus, Kocuria, and Leuconostoc, and one genus of Gram-negative Pseudomonas.
