Recent evaluation of the\n            <jats:italic>in vivo<\/jats:italic>\n            therapeutic efficacy of the few potentially active antibiotics against\n            <jats:named-content xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" content-type=\"genus-species\" xlink:type=\"simple\">M. abscessus<\/jats:named-content>\n            was essentially performed using immunocompromised mice. Herein, we assessed the feasibility and sensitivity of fluorescence imaging for monitoring the\n            <jats:italic>in vivo<\/jats:italic>\n            activity of drugs against acute\n            <jats:named-content xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" content-type=\"genus-species\" xlink:type=\"simple\">M. abscessus<\/jats:named-content>\n            infection using zebrafish embryos.

The status of the infection with increasing drug concentrations was visualized on a spatiotemporal level. Drug efficacy was assessed quantitatively by measuring the index of protection, the bacterial burden (CFU), and the number of abscesses through fluorescence measurements. Both drugs were active in infected embryos and were capable of significantly increasing embryo survival in a dose-dependent manner. Protection from bacterial killing correlated with restricted mycobacterial growth in the drug-treated larvae and with reduced pathophysiological symptoms, such as the number of abscesses within the brain. In conclusion, we present here a new and efficient method for testing and compare the\n            <jats:italic>in vivo<\/jats:italic>\n            activity of two clinically relevant drugs based on a fluorescent reporter strain in zebrafish embryos.
