SUMMARY: We investigated an outbreak caused by non-tuberculous
mycobacteria (NTM) related to breast implant surgery in the city of
Campinas, Brazil, by means of a retrospective cohort and molecular
epidemiological study. A total of 492 records of individuals having
breast surgery in 12 hospitals were evaluated. Twelve isolates were
analysed using four different molecular typing methods. There were 14
confirmed cases, 14 possible cases and one probable case. One
probable, nine possible and 12 confirmed cases were included in a
cohort study; all occurred in eight of the hospitals and the confirmed
cases in five. Univariate analysis showed that patients who had had
breast reconstruction surgery in hospitals A and B were more likely to
have NTM infections. No risk factor was independently associated with
NTM infection in the multivariate model. The isolates obtained from
patients at each hospital showed different molecular patterns,
excluding isolates from hospital C that repeatedly showed the same
genotype for approximately one year. In conclusion, this outbreak was
caused by polyclonal strains at different institutions, and in one
hospital a unique genotype caused most cases. No specific risk factors
were found.
