“Near Absence” of Antibiotics to Combat Deadly New Bacterial Strains
New forms of bacteria are posing nightmarish threats to human health due to the serious lack of antibiotics to combat them.
The Infectious Disease Society of America (IDSA) warned several years ago that cases of infections unresponsive to existing antibiotic drugs were going up, while at the same time the number of medications being developed to treat this problem was low.
Little has changed since then, only now there is a “near absence” of antibiotic candidate drugs capable of combating new strains of bacteria, the IDSA said in a new report (pdf).
The new strains have been called “nightmare bacteria,” due to their resistance to treatments currently available, and that they often result in death. Furthermore, the strains are able to spread their genetic materials to other bacteria, thereby making them resistant to medications as well.
The Centers for Disease Control and Prevention warned in March that there was a fourfold increase in the number of hospitals reporting common Enterobacteriaceae infections that couldn’t be treated with many types of antibiotics. As many as half of the patients infected with Enterobacteriaceae died as a result.
Only two new drugs have come on the market in the last four years since IDSA issued its warning. Those are televancin (marketed as Vibativ) and ceftaroline fosamil (Teflaro). Only Teflaro is capable of combating the new “nightmare” bacteria in its treatment of skin infections and pneumonia.
The slow pace of new antibiotic development by biotech and pharmaceutical firms is primarily due to its lack of financial profitability, a problem that IDSA believes must be addressed by federal government support.
