Streptococcal Profile in Oral of Iraqi Addicted

Abstract

The current study was included identify bacterial profile of the oral Streptococci asso-ciated with abuse substance in addict patients, Seventy oral swabs were collected from addict patients and twenty samples from healthy (control) with age ranged (19-53 ) years. During the period from August (2019) to February (2020) . Abuse sub-stance were detected by using by Immunoassay (ABON™ Multi-Drug - urine ) which is one step screen test panel used for the qualitative detection of multiple drugs in human urine , Isolation of bacteria was done using the enrichment media , differential media , and selective media , and diagnosed according to some examinations methods which included cultural characteristics , Gram-staining and microscopic examination , biochemical tests , and the final identification was performed with API-20 Strep. and Vitek-2 systems . The results appeared that the Streptococcus spp. were predominant in oral cavity , and the S.mutans of Viridans Streptococci species was more frequent with highest percentage in the addict patients when compared with from the healthy individuals , where the S. salivarius was more frequent with highest percentage . The conclusion of this study were the alteration of the normal flora in the oral cavity of addict patients which lead to increased susceptibility to opportunistic infectious pathogens.
