    Abstract: Background: In both industrialized and developing nations, contact lenses have become a popular substitute for eyeglasses. However, unpleasant reactions can develop during contact lens usage in some cases, and a variety of microorganisms—including bacteria, fungus, and free-living amoebae—may cause a variety of eye infections. The goal of this study was to identify contaminated bacteria from contact Wearers. Method: With the use of sterilized cotton swabs, samples were taken from eye lens solution bottles and cultivated directly on solid medium. All samples were inoculated onto blood agar and MacConkey's agar and cultured at 37°C for 24-48 hours. Cultures were declared negative if no growth was detected after 48 hours. On the basis of culture diagnosis by growing on medium and completing biochemical tests, bacteria were identified using Gram's staining. A structured interview questionnaire was used to collect data, which included demographic data as well as risk variables. For data input and analysis of the patient demographic information, the Statistical Package for Social Sciences application (SPSS Inc., Chicago, IL, USA) version 20 was used. Simple descriptive statistics were used to assess the results of the culture, biochemical test, gram stain, and demographic data. Every two variables were compared using the Chi-square test. A statistically significant p value was less than 0.05. Result: A total of 150 samples were taken from an aqueous solution of contact lenses in order to isolate microorganisms. Bacteria were isolated from 84 samples in an aqueous solution, whereas 66 samples were found to be growth negative. Pseudomonas aeurogenosa was the most often isolated bacterium, with 39 (46 %), Stapylococcus epidermidis 27 (32%), Staphylococcus aureus 12 (14 %), and Escherichia coli 6 (7%), respectively. Conclusion: The research demonstrates a range of bacteria in the contact lens solution under evaluation, with pseudomonas bacteria being the most frequent. In addition, users who shared contact lenses had more isolated bacteria encounters. The most preventive factor was found to be high compliance with lens care practices, whereas inadequate compliance with hand washing before wearing lenses was associated to a high contamination rate.

    Abstract Background: Because syphilis is often asymptomatic, it might go unrecognized. Furthermore, infection transfer from mother to unborn child is a concern. Preventing poor pregnancy effects in relation with maternal infection by screening and treating women for syphilis throughout pregnancy. Aiming at exploring anti treponemal antibodies among pregnant women in Berber Teaching Hospital our study was implemented. Methods: A cross-sectional, hospital based study was performed at Berber Teaching Hospital in River Nile State. Encompassed pregnant women who attended Hospital. Following an explanation of the study’s goal, 100 serum samples were taken, and data was collected from each respondent using an interview questionnaire, 100 blood samples were obtained to identify syphilis anti bodeis. All specimens were analyzed using the Rapid Plasma Reagin test (RPR), which was confirmed by an enzyme linked immune sorbent assay (ELISA) (fortress diagnostics/UK). Statistical Package for Social Sciences (SPSS version 19) was used to manage informational gathered. Results: ELISA found 9% of syphilis positive patients, whereas RPR identified 10%.Age of respondents ranged between 16 to 43 years, 53 % of study participants categorized at (30 – 36 years) and 62 % at third trimester of gestational. The highest prevalence of syphilis was 4 % reported in age group (23 – 29 years) and 5% at third trimester. Conclusion: The syphilis sero-prevalence among pregnant women in the current research was 9% by ELISA and 10% by RPR. More precise and sensitive procedures, such as PCR, must be used to corroborate the findings.
