SUMMARY AND CONCLUSION
This current study aim to the utilization of some marine algal extracts instead of using antibiotics for treatment of some bacterial skin diseases by safe way and avoid the danger of increasing use of antibiotics such as side effects, resistance and high cost.
Thirty two bacterial isolates and ten fungal isolates were randomly collected from patients attending the outpatient clinic of the dermatology of Tanta university hospital, and El Menshawy hospital. Isolates were grown on nutrient agar media and tested for determination of the level of susceptibility to antibiotics, antifungal and to be compared with some algal extracts. Results were summarized as following:
Bacterial isolates were distributed as 13 gram negative bacterial isolates and 19 gram positive bacterial isolates, representing (40.62%) and (59.37%), respectively. The multi-drug resistant bacterial isolates (24 isolates) which were resistant to more than 50% of tested antibiotics were selected and identified by biochemical properties.
Fourteen bacterial isolates (1,2,3,4,9,12,13,17,25,26,28,29,30 and 32) may be Staphyllococcus aureus, three bacterial isolates (6, 7 and 8) may be Pseudomonas, three bacterial isolates (5, 15 and 16) may be E. coli and finally four bacterial isolates (19, 20, 23 and 24) may be Klebseilla. Among the tested bacterial isolates number 9 and 17 recorded the highest multi-drug resistance, so bacterial isolate number 9 was subjected to molecular identification by using 16S rRNA gene sequence. By applying the biosystem 16S ribosomal RNA sequence,
