Gigantic Petri Dish Shows Bacteria Evolving Antibiotic Resistance

The rectangular petri dish has been a staple tool in microbiology laboratories for over a century. It was first invented by Julius Richard Petri in 1877, and since then it has been used to grow and observe bacteria, fungi, and other microorganisms. However, researchers from Harvard Medical School and Technion-Israel Institute of Technology have taken the use of petri dishes to a whole new level.They have build a gigantic rectangular petri dish, measuring over two meters long and half a meter wide. This petri dish is not just impressive in size, but also in the way it visualizes the evolution of bacteria. The researchers coated the dish with a gel containing both antibiotics and a nutrient source for the bacteria to grow on. They then created a gradient of antibiotic concentration across the gel, so that the bacteria could gradually adapt and evolve to become antibiotic-resistant.The result is a stunning and terrifying visualisation of how bacteria can quickly adapt to new environments and develop resistance to drugs. As the bacteria move across the dish, they encounter higher and higher concentrations of antibiotics, which kills off weaker and more susceptible bacteria. However, the few bacteria that are already resistant to the antibiotics survive and thrive, and they pass on their resistance genes to their offspring.Over time, the petri dish becomes a landscape of bacterial colonies, each with their own distinct shape, color, and resistance level. Some bacteria form clusters and tendrils, while others spread out in a smooth and even layer. Some bacteria turn bright green, while others remain red or yellow. The most striking thing about this petri dish is that it shows how quickly and dramatically bacteria can change and adapt to new conditions.This research has important implications for the ongoing problem of antibiotic resistance. Antibiotics have been one of the greatest medical advancements of the past century, but their overuse and misuse has led to the emergence of superbugs that are resistant to most or all antibiotics. This makes it harder and harder to treat infectious diseases and puts millions of lives at risk.By visualizing the process of bacterial evolution in a rectangular petri dish, this research highlights the urgent need for smarter and more responsible use of antibiotics. It also provides new insights into how bacteria evolve and adapt, which could help researchers develop new strategies for combating antibiotic resistance.In conclusion, the gigantic rectangular petri dish created by the researchers from Harvard Medical School and Technion-Israel Institute of Technology is a powerful and fascinating tool for visualizing the evolution of bacteria and understanding the problem of antibiotic resistance. It is a reminder that the world of microorganisms is constantly changing and adapting, and that we need to keep up with them if we want to stay ahead of the curve.

Sterile Non-Treated U-Bottom 96-Well Cell Culture Plates - Pack of 100

IntroductionCell culture is an essential technique used in many fields, including biotechnology, medical research, and pharmaceutical research. It involves growing and maintaining cells from different organisms under controlled conditions in a laboratory setting. Researchers use cell culture plates to cultivate cells efficiently.In this blog, we will discuss 96-well cell culture plates, particularly U-bottom, non-treated, sterile plates, and their use in cell culture applications.What is a 96-Well Cell Culture Plate?A 96-well cell culture plate is a multi-well plate used to grow and maintain cells in vitro. It consists of a plastic plate with 96 individual wells, each with a capacity of 0.32 ml. The wells are arranged in a 12 x 8 matrix, which makes it easy for researchers to handle and analyze multiple samples simultaneously.U-Bottom vs. Flat-Bottom PlatesOne of the critical differences between cell culture plates is the shape of the bottom of the wells. U-bottom plates have a U-shape bottom, which provides more surface area for cell growth and better cell retention compared to flat-bottom plates. Additionally, U-bottom plates are useful for applications such as sedimentation assays and suspension cell culture.Non-Treated vs. Treated PlatesCell culture plates can either be treated or non-treated. Non-treated plates have no surface treatment, which allows researchers to covalently attach various coatings, such as extracellular matrix proteins or growth factors, to the wells. This feature makes non-treated plates ideal for cell differentiation studies and applications that require specific cell culture conditions.On the other hand, treated plates come with a surface treatment that enhances cell attachment. For instance, poly-L-lysine or collagen coatings improve adhesion, while poly-D-lysine coatings facilitate in suspension culture applications. Treated plates are suitable for standard cell culture and analysis experiments.SterilizationCell culture plates must be sterile to prevent contamination by unwanted microbes. Manufacturers use various sterilization techniques, such as gamma irradiation, ethylene oxide treatment, and autoclaving, to ensure sterility. Additionally, the plates are packaged in a controlled environment to prevent contamination during shipping and storage.ApplicationsCell culture plates have numerous applications in various fields. Here are some of the common applications of 96- well cell culture plates:1. Drug DiscoveryCell culture plates are used extensively in the drug discovery process to screen potential drug candidates for their efficacy and toxicity. The 96-well format allows for high throughput screening of multiple compounds simultaneously.2. Cell-Based AssaysCell-based assays are used to measure cellular responses to different stimuli, including drugs, toxins, and environmental changes. The 96-well format allows for the measurement of multiple assays simultaneously.3. Stem Cell ResearchStem cell research requires specialized culture conditions, such as specific extracellular matrix coatings, to maintain cell viability and differentiation. Non-treated 96-well plates provide researchers with the flexibility to coat the wells with their preferred coatings for better stem cell culture.Conclusion96-well cell culture plates are versatile tools in cell culture applications. The U-bottom, non-treated, sterile plates offer a high surface area for cell attachment, better cell retention, and flexibility to customize the culture conditions. In addition, the 96-well format allows for high-throughput screening and simultaneous analysis of multiple samples. When choosing the right cell culture plate, it's essential to consider the application, surface treatment, and shape of the bottom for optimal cell culture conditions.
