Please enjoy this gif I made from footage of a Tetrahymena thermophila cell (the big boi) and E.coli (the smol floaty bits). I don't remember the exact magnification, but I believe it's around 100x. My lab partners and I took this video in my bio lab a couple weeks ago.

Anyone can use it, all I ask is that you credit me if you do.

It is, as tetrahymena are prone to doing, eating and slowly dying at the same time.

Quick and accurate diagnosis of bacteria is often a key element not only in identifying the etiological factor, but also in its fight against it. On a daily basis, whether in "human" or "veterinary" microbiology, we use a set of main microbiological media, which are a quick way to identify these main pathogens. Can we trust them implicitly? NO. Most pathogens will show a characteristic pattern on a given medium, but a few percent will look quite different. And so it was this time. What in macromorphology, gram staining resembled a little larger coccobacilli and there were forms of quite long threads, but the most important on MacConkey's medium were colorless colonies with a slightly pink center. At a glance: Providencia spp.

However, no. After careful identification panel it was lactose negative E. coli. Very rare in veterinary medicine.

Let's remember that all quick tests, identification media or even MALDI TOF are only tools that are supposed to help put a solution, not be the final result. As it is in nature, there are always extremes that we like to forget.

3D-printed chip sensor identifies foodborne pathogens to ensure safer products

- By Nuadox Crew -

Food recalls due to contamination are a common occurrence, often leading to consumer distrust in the safety and reliability of their food and drink. Unfortunately, these recalls frequently happen too late to prevent some individuals from falling ill.

Despite significant efforts by the food industry to combat pathogens, contaminated products still reach consumers, causing illness. A major issue lies in the limitations of the current tools used to screen for harmful pathogens, which are not always effective enough to protect public health.

Researchers from Guangdong University of Technology and Pudong New District People's Hospital, published in AIP Advances by AIP Publishing, have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their goal is to enhance screening processes and prevent contaminated food from reaching consumers.

Detecting pathogens in food is inherently challenging due to their diverse nature and the various environments they can thrive in. According to author Silu Feng, the task is further complicated by factors such as low pathogen concentrations in large food samples, the presence of similar non-pathogenic organisms, and the complex nature of different food types. Existing detection methods, including cell culture and DNA sequencing, are difficult to employ on a large scale, meaning not every batch of food can be thoroughly tested, and some contaminants inevitably slip through.

Current methods also face several limitations, such as lengthy result times, the need for specialized equipment and trained personnel, and difficulties in detecting multiple pathogens simultaneously. These limitations underscore the need for improved detection techniques.

The researchers' innovative solution is a microfluidic chip that uses light to detect multiple types of pathogens simultaneously. This chip, fabricated using 3D printing, can be produced in large quantities and easily modified to target specific pathogens. The chip is divided into four sections, each designed to detect a specific pathogen. When a pathogen is present in the sample, it binds to a detection surface, altering its optical properties. This design allows for the quick detection of several common bacteria, including E. coli, salmonella, listeria, and S. aureus, even at very low concentrations.

Silu Feng highlights that this method significantly improves detection efficiency, as it can rapidly and effectively identify multiple pathogens, with results that are easy to interpret. The research team plans to further develop their device to enhance its applicability for food screening, aiming to make the food supply safer for consumers.

Good E. Coli – Bad E. Coli

In the human gut, there's this tiny bacteria called Escherichia coli, or E.

coli for short. It's like a tiny worker, doing important jobs to keep us healthy, including the good E. coli. It helps with digesting food, taking in nutrients, and keeping our gut happy. But sometimes, it can cause trouble if it leaves the gut, like making us sick or polluting the environment. So, it has two sides: it can be a helpful buddy or a bit of a problem. We need to learn more about it to use its good parts and handle the bad ones. This article aims to show the good side of this bacterium while also talking about the problems it can cause. It's all about understanding and dealing with this tiny but important part of our bodies.

Understanding Good E. coli: The Gut's Microbiome Champion

E. coli, is a bacteria that naturally lives in our intestines. Here there is a lot of good this little guy does. While it can be harmful if it isn't in our intestintes, it is actually helpful. In fact, it is essential to our health. No doubt, it does a lot of good work. For instance, t helps break down tricky foods and makes sure we soak up important stuff like vitamins B and K. Plus, it keeps the balance right in our gut, stopping harmful bacteria from taking over and keeping our whole system healthy. Some studies even show that it can produce chemicals that fight off other bad bacteria. So, having E. coli in our gut isn't just normal, it's actually really helpful for our digestion and keeping us healthy overall.

Get The BEST Probiotics

Harnessing the Power of this Bacterium for Human Health

Using E. coli to help people opens up lots of cool possibilities. Whether it's making probiotics or delivering medicine straight to where it's needed, this little bacterium can do it all. Probiotics with good E. coli can boost our digestive system by adding more helpful bacteria to our gut. Scientists have even changed this bacterium to carry medicine right to specific parts of our body, making treatments more effective. Plus, it's fast growth and ability to make useful stuff have made it super useful in science. It can clean up pollution and even help make fuels. By using it in smart ways, scientists are finding new ways to make people healthier and improve technology.

Good E. coli, Bad E.: Beyond its Natural Habitat

When E. coli leaves the gut, it can cause big problems. While most lives happily in our guts, some types can make us really sick if they get into our food or water. These bad strains, like E. coli O157:H7, make toxins that can cause serious stomach issues and even life-threatening problems. Plus, when these harmful bacteria get into the environment, like in water or on food, it's a big worry for public health. Even though it does important work in our guts, we have to be super careful about it being in the wrong place. That's why we need strict rules about food safety and keeping our environment clean—to stop these potentially harmful E. coli from making us sick.

Navigating the Balance: Maximizing Benefits, Minimizing Risks

To handle this bacterium well, including the good E. coli, we need to do a lot of different things. First, we need to teach everyone about washing up and keeping food safe so they don't get sick from it. We also need rules and ways to check our food and water to make sure they're not contaminated with this bacterium. Scientists are working hard to understand how different strains work, so we can find ways to control them better and treat people who get sick. By getting scientists, leaders, and health experts to work together, we can use the good E. coli while keeping everyone safe from the bad ones. It's all about staying watchful and doing things to make sure it  helps, not hurts, our communities.

Get The BEST Probiotics

Conclusion

Handling this bacterium means doing a lot of things to keep us safe We teach people about washing up and keeping food clean. We make rules to check our food and water for E. coli. Scientists study it to find better ways to control it. When everyone works together, we can use the good side of E. coli while keeping the bad side in check. It's about keeping an eye out and taking action to make sure helps us, without hurting us.
