    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: Back ground: The goal of this cross-sectional descriptive study was to isolate and identify several bacterial species in mobile phones among hospital staff at Almak Nimer University Hospital and Shendi Teaching Hospital in Shendi town, River Nile State, North of Sudan. Between December 2019 and November 2020, the research was carried out. Methodology: One hundred (100) swabs were randomly taken from the phones of male and female medical staff volunteers from Almak Nimer University Hospital and Shendi Teaching Hospital, Blood agar and MacConkey agar were used to grow the specimens. Finally, colonial morphology, gram stain, and biochemical tests were used to identify the isolated bacteria. Results: Eighty-seven (87) mobile phones were discovered to be cultured positive in the research (87 %). The isolated organisms were: S. aureus (28; 32%), Coagulase gram negative staphylococci (26; 30%), Bacillus spp (16; 18%), P. aeruginosa (7; 8%), K. pneumonia (5; 6%), E. coli (4; 4%) and Diphteroid (1; 1%). Laboratory technicians (93%) were the most likely to be contaminated, followed by nurses (88%), physicians (80%), and pharmacists (50%). In terms of gender contamination, females account for 87%, while males account for (86 %). Conclusion: The results of this study showed that medical staff's phones might be a source of nosocomial infection.

    Seroprevalence of Treponema Palladium Infection among Blood Donors in Darfur Region, Western Sudan 201
    (جامعة الشيخ عبدالله البدري, 2021-04-10) Mohammed Ahmed Ibrahim Ahmed; Nassreldeen Khalid Abdelrahman; Nahla Ahmed Mohammed Abdurrahman; Mosab Nouraldein Mohammed Hamad; Marawa Ahmed and Mohammed Abd Erahman
    ABSTRACT Background: Treponema palladium (T.P) is a pathogenic bacteria induces syphilis, a systemic disease spread by sexual contact, blood transfusions. Objective: To recognize Treponema palladium seropositive blood donors and to explore the association between syphilis serological evidence and age as well as demographic information. Methods: In Darfur, Western Sudan, a retrospective analysis of sequential blood donation results from January to December 2017 was conducted. Percentages were used to measure the descriptive numbers. The p-value was used to assess the statistical significance of the measure, and the Chi-square was used to test trends. Results: A total of 4527 people volunteered to donate blood. They were all men between the ages of 17 and 49. A total of 493 (10.9 %) donors tested positive for syphilis, while 4034 (89.1 %) tested negative. study showed insignificant correlation between residence and serological evidence of syphilis (P = 0.23). Age was shown to be a strong indicator of transfusion-transmissible infections (P = 0.02). As compared to the other age classes, the frequency of (21-25) and (26-30) years was higher (51/428) 10.6% and (141/971) 12.7 %, respectively. Conclusions: In North Darfur, a high prevalence of Treponema palladium infection has been documented among blood donors. There was no statistically significant association between syphilis and occupancy, although there was a strong prevalence in a particular age demographic with a statistically significant correlation.

    Testicular Size and Male Infertility in Sudanese Patients Attending Khartoum Dermatology and Venereology Teaching Hospital
    (جامعة الشيخ عبدالله البدري, 2021-03-15) Marawa Ahmed Mohammed Abd Erahman; Essam Eldeen Elghazali; Mohammed Ahmed Ibrahim Ahmed; Nahla Ahmed Mohammed Abdurrahman; Mosab Nouraldein Mohammed Hamad; Nassreldeen Khalid Abdelrahman
    Abstract Objective: The study is conducted to evaluate the relationship between testicular volume measured by ultrasound and sperm parameters (volume, count, motility, significant leukocyte and morphology) in Sudanese infertile males attending KDTH, andrology department. Methods: Prospective cross sectional, investigational hospital based study .A total of 100 males were investigated for this study. The testicular volumes of all subjects were measured by ultrasonography. The serial semen samples were collected by the process of masturbation after 3-5 days of ejaculatory abstinence and were analyzed by CASA according to WHO criteria 2010. Results: 74 out of 100 of patients with low Testicular volume had low motility (74%).Correlation between testicular volume and volume of semen, sperm count, morphology and presence of significant leukocyte revealed no significant correlation. Conclusions: Testicular volume had a significant correlation with sperm motility. No significant relation between testicular volume and semen volume, sperm count and sperm morphology. Measurement of testicular volume cannot be helpful alone for assessing fertility at the initial physical examination.
