The extracting of personal sprite from the whole image faced many problems in separating the sprite edge from the unneeded parts, some image software try to automate this process, but usually they couldn't find the edge or have false result. In this paper, the authors have made an enhancement on the use of Canny edge detection to locate the sprite from the whole image by adding some enhancement steps by using MATLAB. Moreover, remove all the non-relevant information from the image by selecting only the sprite and place it in a transparent background. The results of comparing the Canny edge detection with the proposed method shows improvement in the edge detection.

Antibacterial and therapeutic effects of vancomycin-resistant Staphylococcus aureus bacteriocin (VRSAcin) in the treatment of VRSA skin infection in mice

Vancomycin Staphylococcus aureus (VRSA) is a strain of S. aureus that is considered the main cause of bacterial skin and soft tissue infections. It has acquired resistance to vancomycin and represents a therapeutic challenge. The current study aimed to compare the possible therapeutic effects of VRSA bacteriocin (VRSAcin) on the treatment of skin infection in mice with those of an antibiotic (linezolid). The results showed that of the fifty swabs obtained from human skin wounds. One isolate was selected for VRSAcin extraction depending on its antibiotic resistance using an antibiotic susceptibility test.An agar well diffusion test was used to determine bacteriocin’s antibacterial activity

as well as its a minimum inhibitory concentration

minimum bactericidal concentration

and antibiofilm efficiency against gram-positive and gram-negative bacteria that were resistant to many medicines. The freshly developed antibacterial substance VRSAcin shows promise. Bacteriocin from VRSA was extracted and studied the optimal conditions for the Production following Purification of bacteriocin by ammonium sulfate precipitation followed by cation-exchange chromatography. The molecular weight of bacteriocin about (29 kDa) were determined by Sodium Dodecyl Sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The typical conditions for the production of VRSAcin include a pH of 7 and a temperature of 37 ◦C for 48 h. In mice

VRSA-contaminated wounds revealed severe tissue distraction and inflammation that extended to the hypodermis

while VRSA-treated skin showed mild changes and localized lesions to the epidermis and upper dermis. The skin of linezolid ointment-treated mice showed moderate to severe changes. In conclusion

VRSA strain infections in human burned skin were more common than expected. In vivo studies in mice indicated that wounded skin infected with VRSA can be treated with VRSAcin as an antibacterial agent that promotes healing processes with obvious superiority to linezolid ointment. As a result

the VRSA develops bacteriocins that are appropriate for regulating AMR

Gram-positive and Gram-negative bacteria

and may be useful in wound dressings.
