Phage in the diagnosis and treatment of tuberculosis.

23:17 EDT 19th April 2014 | BioPortfolio

Summary of "Phage in the diagnosis and treatment of tuberculosis."

The serious global TB epidemic coupled with limited diagnostic and therapeutic technologies necessitate the study of the role phage in TB treatment. Mycobacterium phage have been used for TB diagnosis, but the accuracy of such methods needs to be improved. Phage have various advantages in treating many kinds of bacterial infection, and coupled with the abuse and misuse of antibiotics, and the increasing prevalence of drug-resistant bacteria, they have been studied as a novel therapy to support antibiotics. The study of phage in TB therapy has developed from the selection of appropriate phage to the simultaneous use of multiple phage and even the use of purified lyase proteins. Though phage have great potential in TB therapy, the technology is still in the in vitro and animal experiment stages, and needs further study.

Medical and Biotech [MESH] Definitions

Voluntary agencies concerned with prevention and treatment of tuberculosis.

A protein extracted from boiled culture of tubercle bacilli (MYCOBACTERIUM TUBERCULOSIS). It is used in the tuberculin skin test (TUBERCULIN TEST) for the diagnosis of tuberculosis infection in asymptomatic persons.

The dormant form of TUBERCULOSIS where the person shows no obvious symptoms and no sign of the causative agent (Mycobacterium tuberculosis) in the SPUTUM despite being positive for tuberculosis infection skin test.

Bacteriophages whose genetic material is RNA, which is single-stranded in all except the Pseudomonas phage phi 6 (BACTERIOPHAGE PHI 6). All RNA phages infect their host bacteria via the host's surface pili. Some frequently encountered RNA phages are: BF23, F2, R17, fr, PhiCb5, PhiCb12r, PhiCb8r, PhiCb23r, 7s, PP7, Q beta phage, MS2 phage, and BACTERIOPHAGE PHI 6.

Tuberculosis of the brain, spinal cord, or meninges (TUBERCULOSIS, MENINGEAL), most often caused by MYCOBACTERIUM TUBERCULOSIS and rarely by MYCOBACTERIUM BOVIS. The infection may be limited to the nervous system or coexist in other organs (e.g., TUBERCULOSIS, PULMONARY). The organism tends to seed the meninges causing a diffuse meningitis and leads to the formation of TUBERCULOMA, which may occur within the brain, spinal cord, or perimeningeal spaces. Tuberculous involvement of the vertebral column (TUBERCULOSIS, SPINAL) may result in nerve root or spinal cord compression. (From Adams et al., Principles of Neurology, 6th ed, pp717-20)
