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.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
