Are we in post antibiotic era?
The ‘post-antibiotic’ era is near, according to a report released today by the World Health Organization (WHO). The decreasing effectiveness of antibiotics and other antimicrobial agents is a global problem, and a surveillance system should be established to monitor it, the group says.
What is the difference between MDR and XDR TB?
Extensively drug-resistant TB (XDR TB) is a rare type of multidrug-resistant tuberculosis (MDR TB) that is resistant to isoniazid and rifampin, plus any fluoroquinolone and at least one of three injectable second-line drugs (i.e., amikacin, kanamycin, or capreomycin).
What is the meaning of XDR?
Extended Detection and Response (XDR) is a consolidation of tools and data that provides extended visibility, analysis, and response across networks and clouds in addition to apps and endpoints. XDR is a more sophisticated and advanced progression of endpoint detection and response (EDR) security.
