Material type: materialTypeLabelBookPublisher: 2015Description: 44p.Subject(s): Department of Molecular Biology and BiotechnologyDDC classification: 2342-T Dissertation note: The saliva contains numbers of proteins which act as antimicrobial agents and these peptides called as antimicrobial peptides. The saliva contains numerous antimicrobial peptides the main salivary peptide present in saliva is Histatin protein rich in Histidine amino acid. Histatin is only antimicrobial peptides present in primates like monkey chimpanzees and human. It’s also contain anti-fungal as well as anti-bacterial effect against staphylococcus aureus. In this study showed the effect of human salivary Histatin against staphylococcus aureus. Salivary Histatin may show antibacterial activity against Staphylococcus aureus with its efficiency having link to age, gender and diabetic status. Total sixty-four saliva sample will be collected on the basis of gender, age and presence of diabetic status. The antibacterial activity of saliva was observed against Staphylococcus aureus by disc-diffusion method. DNA was extracted and HTN1 gene was amplified using specific primer. This study was helpful in demonstrating antimicrobial ability of Histatin proteins present in human saliva. It also provide insight with regards to age, sex and/or immunocompromising ailment (in this case, diabetes) having an effect on the ability of these proteins, thus, opening new doors when it comes to combating fungal infections in both human and animal subjects. The HTN1 gene sequenced and BLAST results proof that variation in Histatin anti-bacterial property in diabetic patients and was not due to mutation in the nucleotide sequences of the decreases in salivary Histatin was due to other reason not due to mutation in these individuals. The age bases study HTN1 gene BLAST results was found 99% similarity with the other age groups. Summary 40 The statistical analysis of healthy people with age and zone of inhibition was found ANOVA P<0.000. The increases of age will decreases the salivary Histatin anti-bacterial properties. The optimum antibacterial activity was measured 2cm in diameter. The present results indicated that healthy human saliva possess antibacterial ability against Staphylococcus aureus. The results indicated that salivary Histatin can be novel tool as antimicrobial peptides of future medical field.
