Here, we present the draft genome sequence of ITALIC! Mycobacterium bovisBCG S4-Jena, a tuberculosis vaccine strain. The genome of S4-Jena is represented by 48 scaffolds, consisting of 132 scaffolded contigs and amounting to a size of about 4.2 Mb. New genes potentially encoding a phage fragment were identified in the genome.

When Mycobacterium bovis BCG and Staphylococcus aureus were plated on agar containing increasing concentrations of fluoroquinolone, colony numbers exhibited a sharp drop, followed by a plateau and a second sharp drop. The plateau region correlated with the presence of first-step resistant mutants. Mutants were not recovered at concentrations above those required for the second sharp drop, there...

A substantial change has taken place in recent years in the approach to the prevention of leprosy through antituberculosis vaccination. Since 1939 efforts have been made to start trials of BCG vaccine on humans as a prophylactic measure against malign leprosy. The third Pan-American Conference on Leprosy held in Buenos Aires in 1951, in connection with a subject of its agenda, "Actual Status of...

Mycobacterium bovis BCG is one of the most commonly administered vaccines. Complications, including disseminated BCG disease, are rare but increasingly reported in immunodeficient children. There is growing recognition of the importance of differences between BCG vaccine strains. We determined the susceptibilities of five genetically distinct BCG vaccine strains to 12 antituberculous drugs.

Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB), infects one-third of the world’s population. While most infected individuals develop latent TB, 5–10% of infected individuals develop active TB. In addition, although most infected people with latent TB remain asymptomatic, they have approximately 10% lifetime risk of developing into active TB. This results in approxima...

In 10-week-old infants vaccinated at birth with Japanese Mycobacterium bovis BCG, the number of dermal needle penetrations correlated positively with frequency of proliferating CD4(+) T cells in whole blood following BCG stimulation for 6 days but did not correlate with secreted cytokine levels after 7 h or interferon CD4(+) T-cell frequency after 12 h of BCG stimulation.

An effective new vaccine for the control of tuberculosis is badly needed. While current research attempts to improve vaccination are concentrating on new prophylactic or immunotherapeutic vaccines, virtually no emphasis has been placed on boosting individuals already inoculated with Mycobacterium bovis BCG. It is shown here that mice vaccinated with BCG gradually lose their capacity to resist a...

In this study, the clinical and immunogenetical features in a cohort of Chinese patients with BCGosis/BCGitis were investigated. For the patients with abnormal immunological functions, Sanger sequencing was used to identify the involved genes. There were 74 confirmed cases of BCGosis/BCGitis during 2007-2012. Classified by infected tissues and organs, no cases only had local infection, 39 patie...

Mycobacterium bovis bacillus Calmette-Guérin (BCG) is the only vaccine available against tuberculosis, and the strains used worldwide represent a family of daughter strains with distinct genotypic characteristics. Here, we report the complete genome sequence of M. bovis BCG Korea, the strain that will be actually used in Korea for vaccine production.
