Introduction: Burns are common medical infections that examined in hospitals. Cytokines are produced by innate immune response; cytokines determine the type of adaptive immune response. This study aims to screen and evaluate the role of IL-2 and IL-6 levels in the serum of patients who have suffered from burns by ELISA technique. Methods: Seventy serum samples were collected from burned patients in Baghdad city hospitals and tested by ELISA technique to detect IL-2 and IL-6 levels. Results: Shows great differences in IL-2 level of male patients (30.16 pg/ml) compared to males control group by an average of (29.66 pg/ml). While IL-6 shows significant differences in female patients with range (63.39 pg/ml) and male (66.47 pg/ml) compared to females control group (2.48 pg/ml) and males (22.80 pg/ml). Moreover cytokines shows significant differences between the three age groups of burned patients in comparison with the control group. In conclusion the result of present study showed significant difference in level of some cytokines IL-2,IL-6 for patients with burns. Conclusion: the result of present study showed significant difference in level of some cytokines IL-2, IL-6 for patients with burns.
Introduction:Klebsiella pneumoniae are Gram-negative which cause many diseases such as urinary tract infections, respiratory tract infections and septicemia. Inulinase is an enzyme used in food manufacture and pharmaceuticals. Inulinase is used in decreasing lipid ratio and, cholesterol in blood and considered as a prebiotic factor inside intestine. Many microorganisms can produce inulinase, such as yeast, fungi and bacteria; among such bacteria: Bacillus spp., Arthrobacter spp., and Pseudomonas spp. but there are no studies about inulinase production by K. pneumoniae have been reported. So the current study aims at investing the ability of producing and purification inulinase by K. pneumoniae. Method: K. pneumoniae were isolated from many hospitals and screened for the production of inulinase. Isolation percentage was 32%. A combination between the enzyme and the ceftazidime were assayed for detecting the antibacterial activity agonist Gram positive and Gram negative bacteria were done. Results: It is found that K. pneumoniae K4 isolate is the best producer of this enzyme. Inulinase, purified with ammonium sulfate at 70% saturation with specific activity 7.01 U/mg protein. As well, it's found that inulinase had increased the activity of ceftazidime against bacteria when combination between this enzyme and the antibiotic had done. Conclusion: This study proves for the first time that K. pneumoniae can produce inulinase which can be used in tremendous applications and also proves the broad spectrum bioactivity of inulinase against microbial pathogens. Ceftazidime antimicrobial activity against bacteria, is increased when a combination between inulinase and ceftazidime had done.
Background: Various microbes involved in alkanes degradation or reducing organics oil products have been identified among. The goal of this work was to screen the soil bacteria with potential ability to degrade alkanes and characterized using a combination of genetic and physiological methods.Methods: The microbial species of soil sample was isolated and the loss of hydrocarbon was calculated periodically by gravimetric analysis. Isolated bacterial strain with potential ability to degrade the engine oil in Baghdad city was further tested for hydrocarbon-degrading abilities using 2, 6-DCPIP. Colonies of bacteria were counted using serial dilution methods of the soil sample. One of the highly bioactive degrading strains ISN53 was selected and a different fraction of crude extract were analyzed for their hydrocarbon degrading activity. The purified active fraction characterised in LC/MS and SDS PAGE. Presence of chlorocatechol dioxygenases was checked by PCR and expression was analyzed in RT PCR. The envelope of ISn21 isolate was checked for any changes under different conditions using microbial adhesion to the hydrocarbon test (MATH). Results: Serratia marcesens (Sm53) and Acinetobacter venetianus (ISn21) were isolated and ISn21 showed maximum growth on the third day and up to 72% degradation on the 7th day of incubation. LC-MS/MS spectrometry analysis identified the bioactive enzyme catechol dioxygenases in crude extract. The purified catechol dioxygenases enzyme had 35 kDa weight which showed the maximum activity between 48 to 72 hour of incubation. The expression of its gene was 2 fold more than control the maximum expression was observed at 60 to 72 hours of incubation. ISn21 was extremely hydrophobic both in MMV and in LB medium.Conclusion: Using a naturally available resources would be better with efficiency at degrading diesel. Use of like microorganisms during bioremediation operation might supply worthy advances in this important biotechnological/ biological domain.
