In contrast, our MIC’s decreased when testing doxycycline, suggesting these deleted proteins may help power the efflux of this antibiotic. Intriguingly, deletions in the newly discovered TtpB2 and/or TtpD2 in the TonB2 system had to be present in order to see a decrease in MIC value, not a TonB protein specifically.

Our analysis shows a high prevalence of antibiotic-resistant microorganisms of the ESKAPE group, as well as epidermal staphylococci, which play a role in the occurrence of postoperative purulent-septic infectious conditions in patients treated in surgical hospitals. This situation requires constant monitoring of antibiotic susceptibility of microorganisms, the implementation of anti-epidemic measures to curb the spread of infection.

[VIRTUAL] In Vitro Activity of Tigecycline and Comparator Agents Against Gram-negative Isolates, Global 2016-2019 (Poster Hall) - May 9, 2021 - Abstract #WMF2021WMF_1459; Based on percent susceptibility (S), tigecycline (TGC), amikacin (AMK), and meropenem (MEM) were the most active agents against Enterobacterales isolates...Only TGC exhibited good activity against CRE, with 93.1% S. Cefepime, levofloxacin and piperacillin/tazobactam had reduced activity against all Enterobacterales and against the CRE subset. The most active agents tested against this global collection of GN isolates were TGC, MEM, and AMK, with >95% S. Antibiotic surveillance programs such as ATLAS are essential to determine global resistance patterns and to monitor changes worldwide.

[VIRTUAL] Short-chain Fatty Acids and Antibiotics Affect Local and Systemic Processes Relevant for Bone Healing () - May 9, 2021 - Abstract #WMF2021WMF_1101; Although butyrate treated animals only show a mild difference regarding bone healing outcomes compared to control mice, rifampicin-levofloxacin treated mice trend to have reduced mineral apposition at the healed fracture site and different mechanical properties of the contralateral, unoperated femur. In conclusion, the composition of the gut microbiota and the presence of bacterial-derived metabolites such as SCFAs may be an important contributor to numerous local and systemic processes relevant to general health and also bone healing.

Journal: Management of antibiotic-resistant Helicobacter pylori infection: current perspective in Iran. (Pubmed Central) - May 8, 2021 Due to increased antibiotic resistance in our region, empirical therapy must be replaced by more targeted treatment based on antimicrobial drug resistance profiles obtained from patients. Although we limited our investigation on the H. pylori eradication regimens in Iran, the results can be generalized to any region as long as the patterns of resistance are the same.
