Enzymes are vital to metabolism and drive countless biological processes in humans, plants, and industry. Yet, when overwhelmed by excess substrate, some enzymes slow down — a phenomenon known as substrate inhibition. This can hinder drug effectiveness and industrial efficiency. Researchers at the Technical University of Munich (TUM) have explored this mechanism and found that beta-carotene may help counteract it.

It’s tick season, and University of Missouri researcher Roman Ganta is fighting back.

As summer heat fuels the rise of lone star ticks across the Midwest and beyond, so too emerges a microscopic menace: Ehrlichia chaffeensis, the dangerous bacterium behind the disease human monocytic ehrlichiosis (HME).

Like all bacteria, this tick-borne killer has potential to evolve and outsmart the antibiotic currently used to treat HME.

How do trees regrow roots after being cut? A new study sheds light on this question using cutting-edge spatial transcriptomics to track how poplar stems regenerate roots. 

A pesky fish may be the culprit behind bleached tropical coral off the coast of the Florida Keys, according to research from the University of Georgia.

Researchers have developed an improved vacuum-infiltration system that overcomes long-standing barriers in tomato genetic engineering. 

Objective: To describe the case of V. ​vulnificus infection and to review the literature, emphasizing the importance of laboratory pathogen biology examination in clinical diagnosis and treatment. Methods: A retrospective review and analyzed a case of a patient infected with septic shock secondary to V. ​vulnificus due to trauma in Nanfang Hospital, Southern Medical University on August 9, 2023. This includes an examination of the symptoms, laboratory results, and treatment process. The BD Phoenix-M50 automatic bacterial identification analyzer was used to identify and test the susceptibility of cultured bacteria, the French Mérieux VITEK® MS IND MALDI TOF was used for identification by mass spectrometry. Results: Skin secretion culture and blood cultures are Vibrio vulnificus bacteria, according to select sensitive antimicrobial drug susceptibility results and surgical treatment after calcitonin original and CRP in patients with infective index returned to normal. Conclusions: Vibrio vulnificus can infect humans through damaged skin and cause wound infection and bloodstream infection. Early wound culture and blood culture are must. Early surgical operation combined with anti-infection therapy is the key to the treatment of Vibrio vulnificus infection to prevent secondary infection endangers the patient’s life. In addition, publicity and education such as preventive measures can also effectively reduce the infection rate of vibrio vulnificus.
