Discover the Microbes Within! Wolbachia Project
Приєднався 15 кві 2021
Discover the Microbes Within: The Wolbachia Project is an integrative lab series designed to bring real-world scientific research into middle, high school and college biology classes through inquiry, discovery, biotechnology, and a culture of excellence. Our goals are to engage students in nature and real-world research, and to contribute new scientific data on the bacterial endosymbiont Wolbachia pipientis.
Discover the Microbes Within! The Wolbachia Project
Join members of the Wolbachia Project as we engage students in nature and real-world research while contributing new scientific data on the bacterial endosymbiont Wolbachia pipientis. The Wolbachia Project covers biodiversity, biotechnology, and bioinformatics, and teaches lab techniques such as DNA extraction, PCR, and gel electrophoresis. Students and scientists collect arthropods in their communities and discover the frequency and distribution of Wolbachia, a bacteria studied for its potential for vector-borne disease control. In addition, they can barcode the insects to determine identity and learn basic bioinformatics skills. They will then report their findings to The Wolbachia Project Database, where they can view entries from participants around the world. We provide PCR primers, controls, and sequencing at no cost thanks to support from the One Health Microbiome Center at Penn State University.
To get started and join the hundreds of classrooms around the globe engaging in the project, visit our website at wolbachiaproject.org/ or contact us at info@wolbachiaproject.org.

Wowwwwwwwwwww just kidding do the full process dude
Woah! Microbes!
please comment your video
Why are you not making other videos cDNA, RNA extraction
Great explanation and visuals!
Thankyou so much from Gadjah Mada University ❤
How about i incubate single body mosquito in 3 hours? Is that more effective than ine hour ?
Thankyou so much ❤️
Please I am looking for lab contact work on Wolbachia, I am looking for a postdoc position
My lab is worried about splash risk while working with field-collected mosquitoes that may contain human pathogens, so pestle homogenization is not ideal for me. Would 3mm stainless steel beads work fine?
i have one question. can we preserve whitefly in 70% Ethanol and extract DNA after 2 months? is it possible?
3:37 You only mentioned ethanol here. The protocol I have suggests an ethanol(90ml)-AL(86ml) mixture. Thanks for the video though. For someone like me who never worked in a lab, it was very useful.
really Thank you so much for sharing those information, as a debutant in molecular biology, I learned a lot from you
thank you for the informative video, / this is Dr Takwa from Tunisia, recently I defended my phd thesis. during my phd I screened wolbachia in the insect I work on. As a post doc, I am very interested to find an internship in this field of work to build my skills and learn more. could you please help me in that?thank you
We Didn’t get dna. All lines we followed except 200 protinase K. We used 30 protinase K. Among 8 samples, we got for two.
This protocol is optimized with a shorter incubation time for classroom use. If you reduce the amount of proteinase K, we recommend increasing the incubation time to enhance lysis. Also make sure to efficiently grind the sample with micropestles.
Hi, your video really helped me! it is well presented short videos, with easy understanding language for science student, and the explanation was really awesome!
Can we extract the DNA from the legs of insects? And do we need to get a fresh sample or alive insects for DNA extraction
Romario, its good that u also watched this video.😄
@@saranga6304 🤣🤣🤣🤣
Yes, Wolbachia can be detected in legs as reported here: www.ncbi.nlm.nih.gov/pmc/articles/PMC3342236/. Most of our participants isolate from fresh samples, but some have successfully amplified DNA from from dead organisms. Make sure to indicate the state of your organism along with any reported data.
I wonder how many people disliked

This is a great introduction. Thanks, Athena!
Thanks for video! It has helped me a lot. I just have one question. I noticed that in the DNA precipitation step, you didn't use the AL buffer as is described in the manual of the product. So, is that buffer optional or just for specific samples?
Great question. Buffer AL is categorized as a lysis buffer, so we added it at 2:47 during the "Cell Lysis and DNA Precipitation" portion of our protocol. Here's a link to the protocol we use, which uses the DNeasy kit for insect extraction: www.qiagen.com/us/resources/resourcedetail?id=cabd47a4-cb5a-4327-b10d-d90b8542421e&lang=en I hope that helps, please let us know if you have further questions! Also feel free to email us at wolbachiaproject(at)vanderbilt(dot)edu.
Great VIdeo! Waiting for Lab 5 ;)
We're hoping bioinformatics whisperer Sarah Bordenstein will feature in Lab 5! :)
This was very helpful!
We love to hear that, thanks!
These videos are great! I'm planning to participate in the Wolbachia Project next year and will definitely use these videos with my students. Thanks!
Thanks, Dan! We're excited to be able to be able to produce these kinds of videos to help students. Let us know if you need anything!
