The study aimed to investigate the effect of anti-lysozyme and IgA antibodies in tear film on the occurrence and growth of microorganisms (bacteria and/or fungi) causing eye keratitis infection. For this purpose (105) corneal scraping samples were taken from patients suffering of microbial keratitis referred to Ibn Al-Haitham Eye Teaching Hospital in Baghdad.
The main aim of this study was obtaining efficient bacteria capable of desulfurizing and/or utilizing organosulfur compounds that found in petroleum and its derivatives. For this purpose oil contaminated soil samples with a history of oil pollution were collected from forty different sites in Iraq.Sixty three bacterial isolates were obtained and these isolates capable to utilize dibenzothiophene (DBT). Results showed that most of these isolates were capable to grow on DBT in the presence or without glycerol (carbon source).
In order to isolate Streptococcus mutans, 80 swab samples were collected from dental caries of patients attended Al-Dora Health Center and Al-Zewiya Health Center in Baghdad city. From these samples, 98 bacterial isolates were obtained. Results of identification depending on morphological, cultural and biochemical tests showed that 10 of these isolates were belonged to Streptococcus mutans. The results of identification were confirmed by using VITEK-Π system. All isolates were screened to examine their ability to mutacin production.
