STUDY OF THE SYNERGISTIC EFFECT OF BACTERIOCIN PRODUCED FROM Leuconostoc mesenteroides ssp. cremoris With Antibiotics Against Multi Resistance Diarrheal Bacteria: STUDY OF THE SYNERGISTIC EFFECT OF BACTERIOCIN PRODUCED FROM Leuconostoc mesenteroides ssp. cremoris With Antibiotics Against Multi Resistance Diarrheal Bacteria

The study included the collection of samples of raw cow milk to isolate Leuconostoc bacteria, samples were sub cultured on De-Man Rogosa Sharpe-Vancomycin medium, the pure colonies were selected and subjected to the cultural and microscopically tests, according to that 25 cocci bacterial isolates were obtained, then isolates were subjected to biochemical tests. Result of tests showed that 12 isolates belong to the genus Leuconostoc out of 25 cocci bacterial isolates, Vitek2 system was used as a supplementary step. Results of final identification showed that 3 sub species were obtained included Leuconostoc mesenteroides ssp. cremoris 9 out of 12 isolates, while it was 2 isolates of Leuconostoc mesenteroides ssp. mesenteroides and one isolate Leuconostoc mesenteroides ssp. dextranicum. The study included the collection of 15 isolate of diarrhea causative bacteria which subjected to cultural and microscopically, biochemical tests and Vitek 2 system, about the results of identification, 9 isolates out of 15 isolates belonged to Escherichia coli,3 isolates of Shigellagroup,2 isolates of Salmonella ser. paratyphi A and one isolate of Vibrio cholerae, the selected isolates were tested to Antibiotic sensitivity test against 11 antibiotics, the results showed that all isolates were resistant to Ampicillin and sensitive to Imipeneme. Screening of L. mesenteroides ssp. cremoris isolates was done to select the more efficient isolate producing bacteriocin by using well diffusion method, the result showed that L. mesenteroides ssp. cremoris (Lc3) and L. mesenteroides ssp. cremoris (Lc4) isolates gave the highest inhibition against E. coli, Shigella group, Salmonella ser. paratyphi A and Vibrio cholerae, the diameters were 13, 12, 12 and 12 mm respectively for the L. mesenteroides ssp. cremoris (Lc3) isolate, while the L. mesenteroides ssp. cremoris (Lc4) isolate diameters were 13, 12, 12 and 11mm respectively. The synergistic effect between bacteriocin of both isolates L. mesenteroides ssp. cremoris (Lc3) and L. mesenteroides ssp. cremoris (Lc4) with antibiotics was studied against multidrug resistant diarrhea causative bacteria. Synergistic effect between bacteriocin of both isolates with antibiotics was observed. The activity of antibiotics with bacteriocin was increased, like Cefixime, Tetracycline, Trimethoprim-sulfamethoxazole, Ampicillin antibiotics against E. coli, and Cefotaxime, Ceftriaxone, Trimethoprim-sulfamethoxazole, Cefixime antibiotics against Shigella group, and Trimethoprim-sulfamethoxazole antibiotic against Salmonella ser. paratyphi A and Ampicillin, Trimethoprim-sulfamethoxazole, Cefixime antibiotics against Vibrio cholerae.

The effect of autologous bone marrow-derived stem cells with estimation of molecular events on tooth socket healing in diabetic rabbits (Immunohistochemical study)
...Show More Authors

Background: Healing of a tooth extraction socket is a complex process involving tissue repair and regeneration. It involves chemotaxis of appropriate cells into the wound, Transformation of undifferentiated mesenchymal cells to osteoprogenitor cells, proliferation and differentiation of committed bone forming cells, extracellular matrix synthesis, mineralization of osteoid, maturation and remodeling of bone. These cellular events are precisely controlled and regulated by specific signaling molecules. Some of these like transforming growth factor beta (TGF-?), vascular endothelial growth factor (VEGF), bone morphogenetic proteins (BMP) and insulin like growth factors (IGF) are well conserved proteins involved in the initial response to injur

The Effect of Different Types of Separating Medium On Some Physical Properties of Processing Acrylic Denture-base with Two Investment Materials: A comparative Study
...Show More Authors

Objective(s): In the present study, glycerin is used as a substitute for tin-foil and cold mold seal (Alginate mould seal)
in the process of curing heat and cold-cure acrylic resin denture base against stone and plaster.
Methodology: 60 specimens were prepared from heat-cure acrylic resin and cold-cure acrylic resin denture base. The
study includes 12 groups of specimens depending on the type of processing, investment material and type of
separating medium that are used in curing process. Each group of them contains 5 specimens for each test.
Some of physical properties of the processed acrylic denture base that (water sorption and solubility) have been
compared with those processed using tin-foil and tin-foil substitut

The impact of the reserve requirement ratio in the activity of the bank credit: Applied Research in a sample of Iraqi private banks
...Show More Authors

The research topic (The Impact of the Compulsory Reserve on the Banks Credit-an applied  research on    a sample of Iraqi banks), was chosen on basis of the Iraqi  private Banks attempts to increase their credit activities in hope to gain more profits.This coincided with  the CBI aim to back the private banking market.It is thus apparent why the CBI issued its regulation to those banks to increase their capitals up  to IDB250. On the other hand,the CBI acted as an obstacle in the way of increasing the private banks of their capitals,that is by implementing the quantitive  monetary tool  so called the compulsory reserve.This is why we intended to overlook at this contradictional  problome
