Drug-opposing bacteria accountable for lethal hospital-obtained infections lock out antibiotics by blocking tiny doors in their cell walls. The new research by scientists at Imperial College London cab permit scientists to develop new drugs that “choose the locks” of these blocked doors and let antibiotics into bacterial cells. The outcome is posted in Nature Communications.
The Klebsiella pneumoniae bacterium is responsible for infections in the blood, lungs, and wounds of people in hospitals, and individuals that have damaged immune systems are particularly vulnerable. Over 20,000 infections from K. pneumoniae were seen in the past year in UK hospitals. Like various bacteria, K. pneumoniae is tuning out to be more and more resistant to antibiotics, specifically a series of drugs dubbed as Carbapenems. Carbapenems are employed as antibiotics in hospitals when others are ineffective or have failed.
Hence, the increasing resistance to Carbapenems can radically impact our capability of curing infections. For this purpose, Carbapenem-opposing K. pneumoniae are categorized as “serious” World Health Organization Priority 1 organisms.
On a related note, a new technique for enduringly marking cells affected with chikungunya virus can disclosed how the virus carries on to cause joint pain for a long time after the original infection, as per a research posted in the PLOS Pathogens journal by Washington University School of Medicine’s Deborah Lenschow and his colleagues. As per the authors, disclosing the mechanisms for long-term disorder can help in the development of preventative measures and treatments for this virally induced, incapacitating chronic arthritis.
Chikungunya virus causes severe muscle & joint pain and is distributed by mosquitoes. Almost 30–60% of people suffering from the virus carry on experiencing joint pain for a long time after the original infection. On the other hand, the reason of this unrelenting joint pain is not clear, as replicating virus can’t be identified at the time of the chronic stage.
