General description

Thioglycollate Medium is a powdered broth medium designed for the cultivation of both aerobic and anaerobic microorganisms. The medium contains dextrose, tryptone, yeast extract, and L-cystine providing essential growth factors for bacterial proliferation. Sodium thioglycollate and L-cystine serve as reducing agents that prevent the accumulation of lethal peroxides, enabling the growth of Clostridium even under aerobic conditions. Resazurin acts as an oxidation-reduction indicator, appearing pink when oxidized and colorless when reduced. The minimal amount of agar in the medium supports the growth of both aerobes and anaerobes, regardless of the presence of sodium thioglycollate. Sodium thioglycollate also neutralizes the toxic effects of mercurial preservatives and peroxides, promoting anaerobiosis and making the medium suitable for testing materials containing heavy metals. Any increase in oxygen content is indicated by a color change in resazurin from colorless to pink. The small agar content helps maintain a low redox potential, stabilizing the medium.

Application

Thioglycollate Medium is widely used in clinical testing, environmental monitoring, food and beverage testing, and sterility testing. It supports the growth of both aerobic and anaerobic microorganisms, making it ideal for sterility control in pharmaceutical products and for testing materials containing heavy metals with bacteriostatic effects. The medium is also used to determine an organism′s oxygen requirements and its ability to grow in anaerobic or microaerophilic environments.

Extracellular SQSTM1 mediates bacterial septic death in mice through insulin receptor signalling.

Borong Zhou et al.

Nature microbiology, 5(12), 1576-1587 (2020-10-21)

Sepsis is the most common cause of death for patients in intensive care worldwide due to a dysregulated host response to infection. Here, we investigate the role of sequestosome-1 (SQSTM1/p62), an autophagy receptor that functions as a regulator of innate

Artesunate protects immunosuppression mice induced by glucocorticoids via enhancing pro-inflammatory cytokines release and bacterial clearance.

Yan Wang et al.

European journal of pharmacology, 890, 173630-173630 (2020-10-13)

Glucocorticoids are commonly used in clinic, but the immunosuppression seriously hinders their usage. Herein, immunomodulatory effect of artesunate (AS) on hydrocortisone (HC)-induced immunosuppression was investigated. HC-induced immunosuppression mice (HC mice) were established by intramuscular administration with HC (20 mg/kg) once a

Macrophage ABHD5 promotes colorectal cancer growth by suppressing spermidine production by SRM.

Hongming Miao et al.

Nature communications, 7, 11716-11716 (2016-05-18)

Metabolic reprogramming in stromal cells plays an essential role in regulating tumour growth. The metabolic activities of tumour-associated macrophages (TAMs) in colorectal cancer (CRC) are incompletely characterized. Here, we identify TAM-derived factors and their roles in the development of CRC.

Sialyltransferase ST3Gal-IV controls CXCR2-mediated firm leukocyte arrest during inflammation.

David Frommhold et al.

The Journal of experimental medicine, 205(6), 1435-1446 (2008-06-04)

Recent in vitro studies have suggested a role for sialylation in chemokine receptor binding to its ligand (Bannert, N., S. Craig, M. Farzan, D. Sogah, N.V. Santo, H. Choe, and J. Sodroski. 2001. J. Exp. Med. 194:1661-1673). This prompted us

The Ap-2α/Elk-1 axis regulates Sirpα-dependent tumor phagocytosis by tumor-associated macrophages in colorectal cancer.

Xiaojiao Wang et al.

Signal transduction and targeted therapy, 5(1), 35-35 (2020-04-17)

The inhibitory receptor signal regulatory protein-α (Sirpα) is a myeloid-specific immune checkpoint that engages the "don't eat me" signal CD47, which is expressed on tumor and normal tissue cells. However, the profile and regulatory mechanism of Sirpα expression in tumor-associated
