Microbiology study reveals link between dust and AMR

Dust Bunny has investigated the microbiological content of dust by isolating bacteria from dust obtained from a range of homes in Accra in Ghana. 

We tested the bacteria for resistance to a number of commonly used antibiotics and found that about 35% of those tested carried resistance to at least one antibiotic and some carried resistance to more than one. 

Some of antibiotic resistant bacteria were identified and no were found to be disease-causing but the majority were opportunist pathogens and could cause disease in people who were already suffering from infectious or non-infectious diseases. 

The most common bacterium found was a non-pathogenic bacterium found in soil but even so it carried a number of resistance which could pass to antibiotic sensitive pathogens making their treatment more difficult. 

Although the sample size was relatively small it showed us that although the dust was a low risk to health with respect to infectious disease, it provides a pool of antibiotic resistance that could compromise future infections.
