Kenyan patients who spend more than three days in the nation’s hospitals are more likely to harbor a form of bacteria resistant to one of the most widely used antibiotic classes, according to a recent study. The research team found that 66% of hospitalized patients were colonized with bacteria resistant to third-generation cephalosporins, compared to 49% among community residents. Third-generation cephalosporins are typically used for serious infections, and resistance to these antibiotics leaves limited options for treating patients with some bacterial infections. The study was part of a pair of projects in Kenya and a third in Guatemala to determine the prevalence of antibiotic-resistant bacteria. The research also aimed to identify risk factors for colonization with bacteria resistant to important and frequently used classes of antibiotics, including third-generation cephalosporins.
