An antibiotic-resistant strain of the bacteria that causes typhoid fever has spread to many countries and reached epidemic levels in Africa, a new study warns.
The strain, H58, emerged in South Asia between 25 and 30 years ago and has slowly grown to become one of the predominant forms of the bacteria Salmonella Typhi, said study author Vanessa Wong, a microbiologist at the University of Cambridge in England.”This multidrug-resistant strain, H58, is resistant to a number of first-line antibiotics used to treat the disease and is continuing to evolve and acquire new mutations to newer drugs,” Wong said.
