“Our standard treatment now is already two weeks of antibiotics and then if they are resistant, then they get an extra two weeks, and then if they are resistant to that, there’s another lot of antibiotics. When people presenting to the clinic have a resistance to antibiotics, they are prescribed multiple rounds of antibiotic treatments, Ong said. “It is very difficult to treat this bug,” he said. Ong said that 15 years ago, MG resistance to antibiotics was around 10-20% among patients at the Melbourne Sexual Health Clinic, but now it was closer to 80-90%. “We are not just seeing this in our modelling work, but in real life.” “It might reduce the prevalence a little bit and control the burden of disease in the community, but actually it makes things worse because the end product of a lot of screenings is we will build a lot of resistance,” the sexual health physician Associate Prof Jason Ong, the lead author of the study, told Guardian Australia. The researchers discovered that while endemic MG prevalence could go down from its current level of 9.1% to 6.4% if all men who have sex with men were offered screenings, it would lead to a high proportion of antibiotic-resistant MG. In a research paper, published in March in journal EClinical Medicine, researchers built a mathematical model of MG transmission based on screening strategies and the prevalences of MG among men who have sex with men attending the Melbourne Sexual Health Clinic.
