How one bacterium inhibits predators with poison:

Microbiologists in South Korea report that the bacterium Chromobacterium piscinae produce cyanide when under attack from Bdellovibrio bacteriovorus HD100, a microbial predator found in streams and soils that ingests its prey from the top to bottom. Scientists found that the prey delivered levels of cyanide sufficiently high to hinder, but not kill, the B. bacteriovorus HD100.
Examinations demonstrated that C. piscinae secrete the defensive cyanide in a nutrient-rich broth. In a medium without supplements, it didn't secrete the cyanide and was consumed. The scientists suspect that the microorganisms likely uses some ingredients in the broth to secrete the cyanide. That perception suggests that microscopic organisms' defenses may depend on location-- and, more generally, that microorganism may harbor defensive components that are activated in a suitable environment, but not in others.
To test whether cyanide alone was dependable or whether some other compound likewise went about as an inhibitor, scientists performed the additional experiments, cleansing and treatment of the supernatant with vitamin B12a. Their outcomes affirmed that cyanide is the main, if not sole, inhibitor responsible. Additionally, experiments likewise demonstrated that vitamin B12a has detoxifying properties that help with the activation of B. bacteriovorus HD100. Along these lines, B. bacteriovorus HD100 can stay away from these guarded components and manage pathogens.
Studying such systems may lead researchers to more readily see how some pathogenic microorganisms protect themselves against antibiotics, says microbiologist and study pioneer Robert Mitchell. His lab at the Ulsan National Institute of Science and Technology, in South Korea, focuses on how microbial prey defends themselves from predators. They are researching how bacterial predators like B. bacteriovorus HD100 may be improved as "living antibiotics " that can target bacterial pathogens.

The research proposes that Microorganisms may have means for resisting predation that exclusive appear in certain environs.

Neisseria gonorrhoeae: Combating a Multidrug-Resistant Organism: The worldwide spread of anti-toxin resistant sexually transmitted diseases (STD) has received increased consideration in the course of recent years from health institutes including the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). In this post we will give a background marked by multidrug-safe Neisseria gonorrhoeae taken after by a depiction of the test techniques clinical labs are utilizing to decide the antimicrobial susceptibilities of N. gonorrhoeae isolates. About Gonorrhea Gonorrhea is a worldwide widespread disease caused by N. gonorrhoeae, a Gram-negative bacterium. As per CDC, roughly 470,000 new gonorrheal diseases were accounted for. Notwithstanding, on the grounds that numerous cases are asymptomatic, and consequently unreported, it is evaluated that there are roughly 820,000 new cases every year. Furthermore, it is assessed that 246,000 of these cases conv

The antibiotic that is active against drug-resistant tuberculosis:  A naturally occurring antibiotic called kanglemycin A is effective against Mycobacterium tuberculosis, the bacteria that cause tuberculosis, even in drug-resistant strains, according to an international team of researchers who used chemistry, molecular biology, microbiology, and X-ray crystallography to show how the compound maintains its activity.  The compound, kanglemycin A, is related to the antibiotic rifampicin, according to Katsuhiko Murakami, professor of biochemistry and molecular biology at Penn State and one of leaders of the project. "Rifampicin is already part of the cocktail of antibiotics used to treat tuberculosis, but many strains of the tuberculosis-causing bacteria have developed resistance to it," Murakami said. "Tuberculosis is the leading cause of death by infectious disease worldwide," said Murakami. "Development of rifampicin resistance in M. tuberculosis has m
