Study TitleResistance to NaFAc of in vitro maturated Toxoplasma gondii bradyzoites in human myotubes.
Study SummaryThe apicomplexan parasite Toxoplasma gondii forms bradyzoite-containing tissue cysts that cause chronic and drug-tolerant infections. Here, we developed a human myotube-based in vitro culture model of functionally mature tissue cysts. In contrast to fast replicating tachyzoite forms of T. gondii these tissue cysts tolerate exposure to the aconitase inhibitor sodium fluoroacetate. These data characterize bradyzoites and tachyzoites treated with NaFAc.

Analysis ID:AN003343
Instrument Name:Thermo Q Exactive Plus Orbitrap
Instrument Type:Orbitrap
MS Comments:The injection order of the samples was randomized, blanks and PBQCs were injected periodically. The samples were analyzed on a Q-Exactive Plus mass spectrometer (Thermo Fisher Scientific) via 70k MS1 scans, with intermittent 35k data-dependent 35k MS2 scans in positive and negative mode separately.XCalibur 4.2.47 software and Compound Discoverer 3.1 software (Thermo Fisher Scientific) was used for recording and used for peak detection, combination of adducts and compound annotation, respectively. Metabolite identifications were based on either retention time and accurate mass match to an in-house library of 160 authentic standards, or by matching accurate mass and MS2 fragments to m/z cloud database (mirrored offline in m/z vault v in May 2020) (Thermo Fisher Scientific). Data were exported to Excel for grouping, combination of datasets from positive and negative ionization runs and blank subtraction..
