1. Antibacterial and anti-virulence effects of furazolidone on Trueperella pyogenes and Pseudomonas aeruginosa
Qin Chen, Kelei Zhao, Heyue Li, Kanghua Liu, Jing Li, Yiwen Chu, Balakrishnan Prithiviraj, Bisong Yue, Xiuyue Zhang BMC Vet Res. 2022 Mar 24;18(1):114. doi: 10.1186/s12917-022-03216-5.
Background: Trueperella pyogenes and Pseudomonas aeruginosa are two important bacterial pathogens closely relating to the occurrence and development of forest musk deer respiratory purulent disease. Although T. pyogenes is the causative agent of the disease, the subsequently invaded P. aeruginosa will predominate the infection by producing a substantial amount of quorum-sensing (QS)-controlled virulence factors, and co-infection of them usually creates serious difficulties for veterinary treatment. In order to find a potential compound that targets both T. pyogenes and P. aeruginosa, the antibacterial and anti-virulence capacities of 55 compounds, which have similar core structure to the signal molecules of P. aeruginosa QS system, were tested in this study by performing a series of in vitro screening experiments. Results: We identified that furazolidone could significantly reduce the cell densities of T. pyogenes in mono-culture or in the co-culture with P. aeruginosa. Although the growth of P. aeruginosa could also be moderately inhibited by furazolidone, the results of phenotypic identification and transcriptomic analysis further revealed that sub-inhibitory furazolidone had remarkable inhibitory effect on the biofilm production, motility, and QS system of P. aeruginosa. Moreover, furazolidone could efficiently protect Caenorhabditis elegans models from P. aeruginosa infection under both fast-killing and slow-killing conditions. Conclusions: This study reports the antibacterial and anti-virulence abilities of furazolidone on T. pyogenes and P. aeruginosa, and provides a promising strategy and molecular basis for the development of novel anti-infectious drugs to dealing with forest musk deer purulent disease, or other diseases caused by T. pyogenes and P. aeruginosa co-infection.
2. Furazolidone and Nitrofurazone Metabolic Studies in Crucian Carp by Ultra-Performance Liquid Chromatography Tandem Mass Spectrometry
Shuai Zhang, Zuisu Yang, Haixia Yu, Yan Chen, Falei Yuan, Xiaojun Zhang, Shuangqi Fang J Chromatogr Sci. 2022 Dec 13;60(10):963-969. doi: 10.1093/chromsci/bmac024.
In this work, the detection of the furazolidone (FZD) and nitrofurazone (NFZ) metabolites residuals in crucian carp are focused. Crucian carps of identical size were exposed to the mixed nitrofuran antibiotics under optimized bath conditions at a concentration of 50 mg/L, 26 ± 0.5°C for 24 h. Then, liquid chromatography-electrospray ionization-triple quadrupole mass spectrometry (LC-ESI-MSMS) was performed after the drug exposure experiments when the nitrofuran metabolites were enriched in organisms. During the period of 0-144 h, residue levels of the 3-amino-2-oxazolidinone (AOZ) gradually decreased with a prolonged sampling time. The changing trend in semicarbazide (SEM) with the sample collection duration is divided into two stages, and its concentration showed a trend of rising first and then falling. The metabolite concentration-time curve demonstrates that 24 h was used as a sampling time, and fish muscle was selected as tissue samples in the further quantitative study. A novel crucian carp-enrichment procedure coupled to LC-ESI-MSMS quantitative method was further explored based on much metabolite data. According to the exponential curve of the SEM-to-AOZ concentration ratio at a precisely designed FZD-to-NFZ mass ratio, the final FZD content of the veterinary NFZ antibiotics was 0.069 ± 0.005% (in terms of mass).
3. Furazolidone Increases Survival of Mice Exposed to Lethal Total Body Irradiation through the Antiapoptosis and Antiautophagy Mechanism
Shumei Ma, Zhao Jin, Yi Liu, Lin Liu, Hao Feng, Ping Li, Zhujun Tian, Minghua Ren, Xiaodong Liu Oxid Med Cell Longev. 2021 Feb 4;2021:6610726. doi: 10.1155/2021/6610726. eCollection 2021.
Exposure to total body irradiation (TBI) causes dose- and tissue-specific lethality. However, there are few effective and nontoxic radiation countermeasures for the radiation injury. In the current study, mice were pretreated with a traditional antimicrobial agent, FZD, before TBI; the protective effects of FZD on radiation injury were evaluated by using parameters such as the spleen index and thymus index, immunohistochemical staining of intestinal tissue, and frequency of micronuclei in polychromatophilic erythrocytes of bone marrow. The intestinal epithelial cell line IEC-6 was used to investigate the underlying mechanisms. Our results indicated that FZD administration significantly improved the survival of lethal dose-irradiated mice, decreased the number of micronuclei, upregulated the number of leukocytes and immune organ indices, and restored intestinal integrity in mice after TBI. TUNEL and western blot showed that FZD protected intestinal tissue by downregulating radiation-induced apoptosis and autophagy. Meanwhile, FZD protected IEC-6 cells from radiation-induced cell death by inhibiting apoptosis and autophagy. To sum up, FZD protected against radiation-induced cell death both in vitro and in vivo through antiapoptosis and antiautophagy mechanisms.
