bacteria
bacteria are single celled microbes. the cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. instead their control centre containing the genetic information is contained in a single loop of dna. learn more about bacteria and why it matters to microbiology here.
-
microbiology today: microbial communities
in this issue of microbiology today we explore saliva and colonisation, eavesdropping on bacterial conversations, sugar-coated bacteria, biofilm development in urinary catheters and microbial ecology of activated sludge.

antibiotic treatment causes some bacteria to sacrifice survival traits
research has found that salmonella biofilms rapidly develop resistance when treated with antibiotics, but with this sometimes comes a trade-off: they do not grow as effectively.

research shows bacteria survive longer in contact lens cleaning solution
research shows that a bacterial strain associated with more severe infections shows enhanced resistance to a common contact lens disinfectant solution.

bacterial cause found for skin condition rosacea
rosacea is a common dermatological condition that causes reddening and inflammation of the skin, mostly around the cheeks, nose and chin. scientists are now closer to establishing a definitive bacterial cause for the skin condition rosacea.
-
microbiology editor’s choice: biofilm formation prevents colistin entry in cystic fibrosis
this study highlights the limitations of generic in vitro biofilm assays that are commonly used to test antibiotic efficacy and provides a tractable model for improved modelling of the cf lung environment and for monitoring drug entry into the biofilm matrix. this study thereby offers aid for antibiotic susceptibility testing in both diagnostics and drug development in the future.
-
bacteria discovered in cornwall
a species of bacteria has been discovered on a man in cornwall. the bacteria was found on a 64-year-old man seeking treatment for cellulitis.
-
what can affect the bacteria in your sink?
in this blog, we learn more about the research of harry ferguson, a third year biological science student who was awarded a harry smith vacation studentship. his project aimed to characterize the culturable gram-negative bacteria found in waste traps collected from a hospital.
-
looking into nature for novel biofilm-modulating agents
antimicrobial resistance (amr) is one of the most difficult problems we face. scientists are increasingly turning to nature to find novel antimicrobials and agents to help in the fight against amr. dr georgios efthimiou from the university of hull is looking for novel agents that can prevent biofilm formation, a phenomenon that can make infections incredibly difficult to treat.

washing your hands is a simple, cheap and effective way of preventing the spread of germs and disease. watch our short video to find out how maintaining hand hygiene can stop infections and help you stay healthy.
-
scratching the surface: how microbes adhere to worktops

jam talks: microbes and medicine
member liam rooney talks us through his research on how bacteria come together to organise in large communities, to how microbes move and swarm in flocks to seek out nutrients and prey.
-
mapping the microbes in your mouth
scientists from the forsyth institute have managed to visualise communities of bacteria in the human mouth, showing their spatial organisation for the first time in 'microbial maps'. the maps could help scientists understand the interactions between different oral bacteria and their potential role in disease.
-
do hand dryers spread viruses in public bathrooms?
seeing someone leave a public toilet without washing their hands is enough to make your stomach turn, but how someone actually dries their hands also has important implications for public health, according to research from the university of westminster.
-
conflict and cooperation in bacterial communities
like humans, bacteria in nature often live in communities. new research studying the interactions within these microbial communities shows how bacteria can cooperate with each other to resolve a form of social conflict.
-
bacterial intruder seeks a warm welcome
among hospital-acquired bacterial infections, staphylococcus aureus is one of the most prevalent. cunningly, this bacterium can evade the body’s natural defences by hiding within the host’s own cells. it seems, however, that s.aureus prefers some cells to others since it is found at varying levels in different bodily tissues.
-
sewage science: are bacteria just the tip of the fatberg?
at aberystwyth university, dr justin pachebat and professor jo hamilton volunteered to help analyse the contents of a london fatberg. we caught up with them to discuss their findings, how they became involved in their research and what challenges they encountered.
-
the bacteriophage - bacteria’s worst enemy?
bacteriophages are composed of proteins and a dna or rna genome that can be very simple, containing four genes, or complex, with hundreds of genes. the phages infect by injecting their genome into the bacteria which disrupts the bacteria’s normal replication cycle.

could household insects be carrying dangerous bacteria?
we all have insects in our homes, be it spiders, flies or bed-bugs. their presence, although sometimes annoying, is not seen as anything sinister. but what bacteria could the creepy crawlies hiding under the sofa be carrying?
