Fate of tetracycline in enhanced biological nutrient removal process.
Liu H, et al. Chemosphere 2018. PMID 29874776
These results clearly suggested that a substantial amount of tetracycline eventually ended up in sludge with the tetracycline content of 23 mg to 4.5 g kg(-1) sludge depending on the tetracycline concentration. ...Furthermore, phthalic anhydride was detected as a biodegradation byproduct of tetracycline, which has been known to be more toxic than tetracycline to aquatic organisms. ...

High Levels of Intrinsic Tetracycline Resistance in Mycobacterium abscessus Are Conferred by a Tetracycline-Modifying Monooxygenase.
Rudra P, et al. Antimicrob Agents Chemother 2018. PMID 29632012 Free PMC article.
Infrequently, tetracyclines can be inactivated by the TetX class of enzymes, also referred to as tetracycline destructases. Low levels of tolerance to tetracycline in Mycobacterium smegmatis and Mycobacterium tuberculosis have been previously attributed to the WhiB7-dependent TetV/Tap efflux pump. However, Mycobacterium abscessus is ∼500-fold more resistant to tetracycline than M. smegmatis and M. tuberculosis In this report, we show that this high level of resistance to tetracycline and doxycycline in M. abscessus is conferred by a WhiB7-independent tetracycline-inactivating monooxygenase, MabTetX (MAB_1496c). ...

Bioavailability of tetracycline to antibiotic resistant Escherichia coli in water-clay systems.
Zhang Y, et al. Environ Pollut 2018. PMID 30253298
The formation of biofilms on clay surfaces could increase bacterial access to clay-sorbed tetracycline. In addition, desorption of loosely sorbed tetracycline into bulk solution contributed to bacterial exposure and activation of the antibiotic resistance genes. Tetracycline sorbed by soil geosorbents could exert selective pressure on the surrounding microbial communities via bacterial exposure to tetracycline in solution from desorption and to the geosorbent-sorbed tetracycline as well....

Magnesium and Drugs
Gröber U. Int J Mol Sci 2019 - Review. PMID 31035385 Free PMC article.
., magnesium, calcium, and zinc can interfere with the gastrointestinal absorption of tetracycline antibiotics) and simultaneously the physiological function of minerals such as magnesium may be impaired by a drug (e.g., diuretics induce renal magnesium loss). ...

Stevensite-based geofilter for the retention of tetracycline from water.
Fernández R, et al. Sci Total Environ 2018. PMID 30016708
The antibiotic tetracycline, is considered a contaminant of emerging concern due to its presence in wastewater effluents, surface waters and groundwaters. ...Besides, the tetracycline is completely desorbed by the inflow of a saline solution (Mg(NO(3))(2) 0.5 M, at pH = 2) with capacity to replace the exchangeable positions, thus, recovering the geofilter and the tetracycline....

A tetracycline-dependent ribozyme switch allows conditional induction of gene expression in Caenorhabditis elegans.
Wurmthaler LA, et al. Nat Commun 2019. PMID 30700719 Free PMC article.
Here we describe tetracycline-dependent ribozymes as versatile RNA-based genetic switches in C. elegans. Ribozyme insertion into the 3'-UTR converts any gene of interest into a tetracycline-inducible gene allowing temporal and, by using tissue-selective promoters, spatial control of expression in all developmental stages of the worm. ...With these advantages tetracycline-dependent ribozymes significantly expand the genetic toolbox for C. elegans....

Tetracycline resistance of Neisseria gonorrhoeae in Russia, 2015-2017.
Shaskolskiy B, et al. Infect Genet Evol 2018. PMID 29883770
Partial recovery of N. gonorrhoeae tetracycline susceptibility was observed relative to the proportion of isolates with resistance detected ten years ago (75%). However, the current levels of tetracycline resistance still preclude the renewed use of these drugs for gonococcal infection therapy....

Simultaneous degradation of tetracycline and denitrification by a novel bacterium, Klebsiella sp. SQY5.
Shao S, et al. Chemosphere 2018. PMID 29913397
Polluted waters with a high residue of tetracycline also have a high concentration of nitrate. Thus, screening for both, highly efficient tetracycline biodegradation and nitrate transformation, is a key technical strategy. ...Biodegradation characteristics of tetracycline were studied under various environmental conditions; including inoculation dose (v/v), initial tetracycline concentration, temperature, and pH. ...
