Previous surveys showed a high prevalence of hepatitis B infection in Yemen. Hepatitis B vaccination is the most efficient way to prevent hepatitis B virus infection and its outcomes (such as hepatocellular carcinoma, cirrhosis, and liver failure). Aim: To measure the immune status of hepatitis B virus amongst first-year students at the faculties of Thamar University during the academic year 2021-2022. Methods: A total 196 of first-year students participated in this cross-sectional study and tested for anti-HBsAg and the antibody to HBV core antigen (anti-HBc) and HBsAg by using ELISA during the period from January to May 2022 at Thamar University. An anti-HBs antibody titer ≥10 mIU/mL was regarded as being protective against HBV infection. Results: In this study, 22.4% of the students had protective levels against hepatitis B, while 77.6% had a non-protective level. HBV markers showe...

Research paper thumbnail of Urinary Tract Infections in Post Operative Patients: Prevalence Rate, Bacterial Profile, Antibiotic Sensitivity and Specific Risk Factors

This investigation seeks to determine prevalence rate, bacterial features, antibiotic sensitivity and risk factors for urinary tract infection in postoperative patients in tertiary hospitals in Sana’a, Yemen. Methods: This prospective analysis included 390 patients undergoing surgery between 2017 and 2018 at Al-Thawra Hospital. The study includes 258 male and 132 female between the ages 5 to 80 years. Clinical and demographic data and factors affecting UTIs were collected in the standard questionnaire, and the sample was obtained after catheter removal; or, in patients with a clinical indication of continuous catheterization, a sample was obtained after the replacement of a new catheter. The samples were cultured, examined for significant possible bacterial pathogens, isolated and identified by...

Research paper thumbnail of Epidemiology, Bacterial Profile, and Antibiotic Sensitivity of Lower Respiratory Tract Infections in Sana’A and Dhamar City, Yemen

The study aimed to identify the general characteristics of LRTI, the causative bacteria and the results of sensitivity to antibiotics. Subjects and methods: A multicentre prospective study was performed at 3 University hospitals. The study included 555 clinical diagnostic cases as LRTI cases, 328 male and 227 female, aged 3 to 69 years. Clinical and demographic data were collected in the standard questionnaire, and samples included sputum or bronchial lavage (BAL) staining and culture. Samples were cultured in 3 different bacterial media, blood agar and LJ slope, chocolate agar with Co2; cultures were then examined for possible bacterial pathogens of LRTI. Possible bacterial pathogens were isolated and identified by standard laboratory techniques, and microbial sensitivity testing was carried out by disc diffusion method...
