Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More
Patients getting medical care can catch serious infections called healthcare-associated infections (HAIs). While most types of HAIs are declining, one -- caused by the bacterium Clostridium difficile --continues to grow. C. difficile causes diarrhea linked to 14,000 American deaths each year. Pa...

Do you eat bread? Or drink beer? If so you've probably consumed yeast products from the National Collection of Yeast Cultures.
Yeasts are one of the earliest, if not the earliest, biological tools used by people. Brewers' yeast, Saccharomyces cerivisae, features widely in products we consume... Read More
During the April 2013 avian influenza A (H7N9) outbreak, more than 130 human infections with H7N9 were reported. Most patients had severe respiratory illness and 44 people have died. Studies suggest that the H7N9 virus has developed resistance to oseltamivir. A human interferon already in use fo... Read More
In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More
The disruption of the human microbiome through use of antimicrobials is a topic of growing interest among healthcare epidemiologists, not only because it is a major risk factor for C. difficile infection (CDI), but also because it could be a driving force behind the introduction and proliferatio...

A green alga with throat- and stomach-like structures can swallow and digest bacteria when deprived of light, further bolstering Lynn Margulis’s widely accepted idea that the origin of the plant-powering chloroplast was a fortuitous bout of indigestion.
Termed “Endosymbiotic Theory“, the idea... Read More

Research on bacterial movement tends to focus on the rod-shaped bacteria. With the aid of small waving flagella, each bacterial cell can push itself in the direction it wishes to go. They can also move in groups, forming large swarms that ripple and slide their way across Petri dishes. Spherical... Read More
Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis. Since the early 1980s, there has been an overall trend of an increase in reported pertussis cases. In this video participants discuss the resu... Read More
Dr. Tanya Parish and her TB Disco Team at IDRI use microbiology to develop new drugs for TB and improve the health of the world! Read More
In Pakistan IDUs is the highest HIV infected risk group, mainly because of frequent sharing of contaminated needles, paid blood donations and unprotected commercial sex. These IDUs are serving as bridge to transfer the HIV to general population transmitting the virus to their wives and children.... Read More
Relapsing clostridium difficile infection (CDI) is a disease that patients face after being medicated with antibiotics that damage their microbiota. A recent and effective treatment to eradicate this condition is known as “fecal material transplant” (FMT), where a healthy human will donate a sam... Read More
Quorum sensing is one of the most amazing things about bacteria. More and more research is focusing on potential quorum sensing applications in biomedicine and many other fields of life sciences.
This is a video that I made about QS for a competition in my University. No previous science bac... Read More
Microbes are essential partners in all aspects of plant physiology, but human efforts to improve plant productivity have focused solely on the plant. Due to the change in environment the pathogenic microbesare growing rapidly whcich gives the negative impact that is diseases to human, animal and... Read More
Growing cells – in a laboratory in space or on earth – forms a fundamental basis of modern microbiology, supporting everything from culturing microbes to novel drug design and growing human tissues for use in research and development. The problem is that cells grown on a 2D Petri dish do not ... Read More
Critically ill patients with the pandemic H1N1 influenza who received triple the standard dose of the influenza drug oseltamivir were 7 times more likely to completely clear the virus from their system in 5 days than those who received the standard dose. This discussion addresses the healthcare... Read More
What effect does the varroa mite, and the viruses it transmits, have on bee colonies? To find out, scientists have developed a new computer model to that simulates a honey bee colony over the course of several years.
Shown in the video on this page, the BEEHAVE model was c0-funded by BBSRC and... Read More
The human body hosts more than ten thousand different kinds of microbes. Most of these bacteria aren't harmful - in fact, many of them actually aid the immune system. From the Smithsonian Channel.

The Geiss Lab at Colorado State University is dedicated to finding ways to prevent or inhibit dengue virus (flavivirus) infection. Dengue virus causes significant worldwide suffering and death, and there are no drugs or treatment options currently available. We are investigating the viral cappin... Read More
