Objective Our study planned to investigate the current positivity rate and distribution of the serologic markers of TTIs among male blood donors of the White Nile state, Sudan. Results The overall reported seropositive cases of TTIs was 15.91%, and percentages of anti-Human immunodeficiency virus 1/2 (anti-HIV1/2), Hepatitis B virus surface antigen (HBVsAg), anti-Hepatitis C virus (anti-HCV), and anti-Treponema palladium (anti-T. palladium) were 2.61%, 5.57%, 1.40%, and 5.72%, respectively. Out of 10897 donors examined, 0.59% had a serological sign of multiple infections. Furthermore, the odds of testing positive for TTIs were higher in the 28–37 age group (OR: 2.620, 95% CI: 2.324–2.955) and lower in the 38–47 age group (OR: 0.671, 95% CI: 0.567–0.794) compared to individuals of 18–27 years old. Likewise, it is more in individuals of Kosti (OR: 1.122, 95% CI: 0.987–1.277) and Rabak (OR: 1.354, 95% CI: 1.188-1.543) localities compared to Al Douiem locality. Anti-HIV/anti-T. palladium (27.70%) and anti-HIV/HBVsAg (23.07%) were the most frequently detected serologic markers of co-infections, P = 0.002.

Background: Hemodialysis patients are exposing to many harms as blood borne viruses. This study was sought to determine the frequency of anti-HIV1/2, and anti-HCV seropositivity among hemodialysis patients attending Kosti Renal Dialysis Center. Materials and methods:A total of 100 blood samples (68 men ,and 32 women) were included in this study that was carried out in Kosti Renal Dialysis center, during the period from 15 August to 20 November 2017. Each sample was tested for anti-HCV , and anti-HIV1/2 by immunochromatographic tests (Humasis) according to manufacture instructions. Results:The frequency of anti-HCV, and anti-HIV1/2 were 5% (5/100), and 0% (0/100) respectively. There is non significant difference in the frequency of anti-HCV between men (4.4%) and women 6.3% or among the duration of hemodialysis.Conclusions: Hemodialysis can expose patients to harms, and infections. Emergence of Blood borne pathogenic infections among hemodialysis patients has become a major public health threat worldwide. Continuous surveillance and implementation of control program can aid in the elimination and eradication of these problems.

Background: Globally, Streptococcus pharyngitis is a major public health challenge. The current study investigates the prevalence of Streptococcal pyogenes among children under 17 years old in ENT Kosti Teaching Hospital and examines the susceptibility of isolated S. pyogenes strains to commonly used antibiotics.Methods: A total of 384 throat swabs were obtained from children under the age of 17 who attended the Kosti Teaching Hospital between 2019 and 2021. Streptococcus pyogenes was isolated by conventional microbiology procedures. Each S. pyogenes strain was subjected to antibiotic susceptibility testing according to the CLSI guidelines.Results: Most participants of this study were females 219 (57%) and aged between 5 and 10 years 259 (67.4%). Out of the 384 participants, 134 (34.9%) and 255 (66.4%) suffered from lymphadenopathy and tonsil hyperplasia, respectively. Interestingly, lymphadenopathy and tonsil hyperplasia were more (P 0.05) in the 5–10 age group than those aged 11–16 years. Moreover, 41.4% of the participants were infected by a GAS sore throat. GAS sore throat is significantly associated with lymphadenopathy (AOR: 2.375, 95% CI: 1.479–3.815, P 0.000) and tonsil hyperplasia (AOR: 3.374, 95% CI: 1.939–5.874, P 0.000). Notably, males (AOR: 0.853, 95% CI: 0.549–1.325, P 0.479) and individuals aged 5–10 years (AOR: 0.867, 95% CI: 0.464–1.618, P 0.654) were less likely to have a GAS sore throat. In our study, all isolated strains were sensitive to penicillin. Clindamycin, azithromycin, and erythromycin resistance were observed in 7 (4.4%), 44 (27.7%), and 47 (29.6%) isolates, respectively.Conclusion: The study displayed the current situation of GAS sore throat in the White Nile state. Penicillin was found to be the effective drug to cure S. tonsillitis but a high rate of resistance to macrolides was noticed which is an alarming sign.
