In age-adjusted univariate analysis, TB predicted the carriage of OXA-1(p = 0.02), catB3 (p =  < 0.01), and dfrA14 (p < 0.01); length of stay in hospital predicted carriage of NDM-7 (p = 0.02) and CMY-2 (p = 0.04); and antibiotics use predicted carriage of CMY-2 (p = 0.03) (Additional File 9: Table S8). The gene discussed is OXA1L; the disease is tuberculosis.
