"Antibiotics are becoming less effective, but big money is in drugs for cancer, diabetes and other conditions, not antibiotics," Anand Anandkumar, CEO of Bugworks, told the BBC.

Bacteria are constantly evolving to evade death. Even the most powerful "last resort" drugs are becoming less effective due to resistance. [3] Without an arsenal of effective antibiotics to treat infections, modern medical procedures – such as chemotherapy and surgeries – are more risky and put patients' lives at risk. [4]
A person cannot become resistant to antibiotics. Resistance is a property of the microbe, not a person or other organism infected by a microbe. [14] All types of microbes can develop drug resistance. Thus, there are antibiotic, antifungal, antiviral and antiparasitic resistance. [4] [8] Antibiotic resistance is a subset of antimicrobial resistance.
Antibiotics such as penicillin and erythromycin, which used to have a high efficacy against many bacterial species and strains, have become less effective, due to the increased resistance of many bacterial strains.
“Antibiotics are chosen very carefully based on the patient being treated — e.g., age, weight, kidney function — the type of infection being treated and the bacteria causing the infection ...
In viruses, an equivalent "cost" is genomic complexity. The high metabolic cost means that, in the absence of antibiotics, a resistant pathogen will have decreased evolutionary fitness as compared to susceptible pathogens. [34] This is one of the reasons drug resistance adaptations are rarely seen in environments where antibiotics are absent.
An antibiotic already in use in Europe to treat pneumonia controlled deadly bloodstream infections with Staphylococcus aureus bacteria just as effectively as the most powerful antibiotic currently ...
