Association of genotype III of dengue virus serotype 3 with disease outbreak in Eastern Sudan, 2019.

Background: Dengue fever (DF) is an arthropod-borne disease caused by dengue virus (DENV). DENV is a member of the genus Flavivirus in the family Flaviviridae. Recently, DENV has been reported as an important emerging infectious viral pathogen in Sudan.

Tuberculin reactivity in schoolchildren, Kassala State, Sudan.

Background: Tuberculin skin test (TST) is widely used for the assessment of Bacillus Calmette-Guérin (BCG) vaccine efficacy and screening of latent TB infection (LTBI). Poor or no data are available on the reactivity of tuberculin in Kassala State. The aim of the present study was to assess the response to the BCG vaccine and to estimate the prevalence of LTBI and the annual rate annual risk of tuberculous infection (ARTI) among vaccinated school children using TST.

Recent transmission of dengue virus and associated risk Facors among residents of Kassala state, eastern Sudan.

Background: Acute arboviral infections are distributed worldwide including Sudan, and dengue fever (DENV) is not an exception. The virus activity has recently been frequently reported in Kassala State, eastern Sudan. However, an appropriate epidemiological study would be necessary to provide accurate and precise estimates of the magnitude of recent DENV transmission in this area of endemicity.

Molecular identification of causing Pulmonary Tuberculosis in Sudan.

Background: Tuberculosis (TB) is a major public health problem in Sudan. However, the strains responsible for the epidemic of TB have been poorly characterized. The aim of this study was to characterize the causative agent of TB isolates circulating in Kassala and Gezira States during 2011-2012.

Tuberculosis drug resistance isolates from pulmonary tuberculosis patients, Kassala State, Sudan.

Background: This study was conducted in Kassala Teaching Hospital, Kassala State, Sudan (January 2006-June 2008) to determine the rate of mycobacterium drug resistance to anti-tuberculous treatment and to explore the genotype of Mycobacterium tuberculosis resistant isolates using rpoB gene.

Methods: 53 isolates of mycobacterium isolated from pulmonary tuberculosis (PTB) patients from Kassala State were subjected to drug susceptibility testing (DST) to anti-tuberculous drugs; 10 M.tuberculosis complex (MTBC) resistant isolates were subjected to polymerase chain reaction (PCR), and commercially the amplified DNA was sequenced.

Genotyping of Pulmonary Isolates from Sudan Using Spoligotyping.

Tuberculosis (TB) remains a major public health problem worldwide due to its high risk of person-to-person transmission, morbidity and mortality [1]. Sudan has a high burden of tuberculosis. Spoligotyping (spacer oligonucleotide typing) a rapid method for genotyping of using the principle of reverse hybridization.
