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 d

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
