"Colorectal cancer is the fourth most common cancer and the fifth leading cause of cancer death worldwide. Two important hallmarks of the disease are faulty tumor suppressor genes and altered composition of the community of microbes that live in the colon. That prompted researchers to explore whether there is a connection between the two. They examined 33 tissue samples from patients with colorectal cancer. Protein-assisted DNA sequencing revealed the prominence of Fusobacterium nucleatum, pathogenic bacteria associated with gum disease, and Hungatella hathewayi, rod-shaped bacteria with no substantial track record of causing disease. Further experiments showed that these bacteria can actually mute genes that normally suppress cancer, promoting the spread of colorectal cancer cells. The findings are unexpected evidence that bacteria in the colon can regulate genes linked to cancer suppression and reveal at least a few targets for anti-cancer therapy..."

In this presentation, we talk about adaptation and evolution of bacteria. Furthermore, we will discuss how you can work with or against evolution, regarding the treatment of bacteria and biofilms.

This presentation introduces bacteria and biofilms. Where do we find bacteria? Is it possible to live without bacteria? Should we be scared of bacteria?

In this presentation, we will talk about diagnosis of bacteria and chronic infections in clinical practices. We will discuss why we need to diagnose bacteria in infections and what the biggest challenges are in diagnosing bacterial and chronic infections. Finally, we will discuss what the future will bring, regarding bacteria and diagnosis.

In this presentation, we will talk about bacteria, and the two life forms planktonic and biofilm growing bacteria. In continuation of this we will explain the difference between planktonic and biofilm growing bacteria.

The aim of this presentation is to expand the student knowledge about skin microbiology. The main skin microbes are bacteria, viruses and fungi, which normally are friendly without causing harms. However, the skin flora is constantly challenges by our every-day life activities.

"The birth of a child involves many big transitions, but one of these changes occurs inside the child, who transitions from the sterile womb to an outside environment full of microbes. While this has lasting effects on growth, inflammation, and immunity, remarkably little is known about how gut bacteria and viruses are acquired by infants. Recently, researchers used next-generation sequencing to evaluate microbes from the guts of 28 pairs of twins and their mothers. They found that the majority of the infant’s gut bacteria were similar to their mother’s gut bacteria. Viruses were less similar, suggesting they might be transmitted through other routes. Twins also shared more of their gut microbiota with each other, emphasizing the strong effect of environmental exposure, and mode of delivery had very little effect on how much of the infants’ gut microbiome was inherited from their mothers..."

"Crohn’s disease is an incredibly painful inflammatory bowel disease that frequently reoccurs after treatment. The growth of a certain type of abdominal fat has been associated with Crohn's disease recurrence. This fat, called mesenteric adipose tissue, is tucked up against the membrane connecting the intestines to the abdominal wall. Microbes can escape the intestines in Crohn's disease and may affect the mesenteric fat. Recently, researchers explored this relationship by investigating the mesenteric microbiome of patients with Crohn’s disease. Crohn’s disease patients had distinct mesenteric microbiomes, host gene expression patterns, and metabolites compared to controls. To explore the specifics, the researchers isolated bacterial strains from the mesenteric microbiome of these patients. In a mouse model of colitis, introducing a mixture of five of the isolated bacterial strains made disease symptoms worse. One of these strains, _A..."

"Microbes are all around us. With around the same number of bacteria as cells in each human body, our microbiomes are constantly interacting with microbes in the surrounding environment. And indoor environmental microbes can influence our health, affecting allergies, asthma, and other health conditions. To better characterize indoor microbial communities, researchers conducted an environmental assessment as part of an epidemiologic study of 50 elementary schools in a large city in the United States. They identified more than 2,000 bacterial species in floor dust collected from 500 classrooms. The most abundant bacterial phyla were Firmicutes and Proteobacteria, and interestingly, the genus Halospirulina was reported for the first time in a classroom sample. Outdoor-associated and gram-negative bacteria were more abundant in classroom floor dust compared to homes, where human-associated and gram-positive bacteria are more abundant..."

"Trees support so much life on Earth – but one important component might easily be overlooked. The phyllosphere – the aerial surfaces of plants, including leaves – is a microbial habitat for diverse microorganisms. Phyllosphere bacteria play key roles in plant health, human health, and ecosystem function, but unfortunately, not much is known about how plants and their associated microbes influence each other. A recent study evaluated this relationship in a diverse neotropical forest. Using shotgun metagenomics, researchers found that the metabolic functions of phyllosphere microbes varied based on their tree hosts. While overall there was low variability in plant-associated microbes, suggesting that certain microbes form a “core microbiota” for neotropical trees, bacterial metabolism and membrane transport functions varied between plant species..."

Biochemical Oxygen Demand" is an essential educational resource tailored for environmental science and engineering students, aiming to deepen their understanding of water quality assessment and pollution control. This unit comprises a series of engaging lessons, each meticulously designed to explore the dynamics of Biological Oxygen Demand (BOD) and its implications for aquatic ecosystems.Beginning with foundational concepts of dissolved oxygen and BOD, learners progress to advanced topics such as the Dissolved Oxygen Model and SAG (Submerged Aquatic Growth) curve analysis. Through interactive discussions and problem-solving exercises, students develop proficiency in calculating key parameters related to water quality, including DO concentrations and BOD levels.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This 18-minute video lesson provides an introduction to bacteria. [Biology playlist: Lesson 18 of 71].
