In an attempt to keep these lectures on antibiotics from becoming too expansive (and thus difficult to complete their viewing), I chose to focus just on those bacteria that cause acute infections. I've gotten a number of requests for other topics, so I can't give a projected time this will happen, but I definitely hope to come back to spirochetes and mycobacteria, along with fungi, HIV, and some highly prevalent tropical diseases not otherwise covered (e.g. malaria). Thanks for watching!
Knowledge of the catalase test (which is primarily used to differentiate staph and strep) is not helpful outside of the micro lab and med school tests. Differentiating GAS vs. GBS, and pneumoniae vs. viridans is really important however, as each causes different diseases and responds differently to abx. It's just that the knowledge of the tests used to make that final distinction are usually not needed by people interacting directly with patients. But critical if you are a microbiologist.
214kennedy, I'm glad you have been enjoying the lectures here. Unfortunately, my exposure to online discussion of any kind is more or less limited to RU-vid comments and Facebook posts. Best of luck with your endeavors.
Great thanks a lot!! For the first time I could understand microbiology and antibiotics 👍🏻👍🏻 can I have this lecture as pdf document? It was so helpful for me
thanks for the response and for the effort of putting this information together in a way that was not just a great review and also a great learning tool. I only wish this had been available to me when I was in vet school in the early 90s. I look forward to what you present in regards to zoonotic diseases and (if u fancy) the nuances of the veterinary world. Unfortunately veterinary microbiologist wouldn't create such a wonderful tool as u have. thanks again
Omg thank you so much my microbiology professor is terrible he didn’t tell my class about the classification of bacteria he told us to google it. I really wish you were my professor you made this lecture so relaxing and easy to understand. Can you do a video on Growth Media (Chocolate Blood Agar, TSA, MSA, and Nutritive Agar) and tell me what I should look for as in diseases. Can you also explain the difference between SBA and Chocolate Agar and why some organisms grow on one plate but not the other and lastly can you explain what’s the selective and differential agent in each plate I have no idea what my professor is talking about. Hope you can help. I will keep looking to see if you have anymore Microbiology videos. Thanks for all your help you are fantastic! 😁⭐️⭐️
Great review. I wish you hadn't skipped the Veterinary related bacteria. Now I understand the intense confusion and delayed diagnosis when one of my colleagues come in after being injured by an animal. Human med seems to be slow to look outside of their own box.
+CurlyAnji11 I'm sorry you found the video to not be completely thorough. It was only intended to cover "conventional" bacteria, not because zoonotic organisms (and TB and syphilis for that matter) aren't important, but because learning micro is easier if it's done in digestible chunks. I've got notes written up of about 15 zoonoses, with the intention of eventually having a video for each one. But there have been so many other requests and competing priorities that I just haven't gotten to it yet.
This particular playlist is focused on abx to treat acute bacterial infections. Since TB tends to cause subacute & chronic infections, I hope to cover them at a future time (along with malaria, HIV, and a few others). The length of the videos would just be too long if I tried to cover everything at once. In the meantime, the Khan Medicine RU-vid channel has an informative 6 video series on TB that I'd recommend if this is a topic of particular interest to you. Thanks for watching!
Strong Medicine The video is very well made, You are doing an amazing job..... just quickly wanted suggest maybe Spirochete (in particular T pallidum) should have been included here. Thank you.
Which Bacterium in your opinion Eric, do you think is the most dangerous? I for one think Mycobacterium, Yersinia and Streptococcus are the most dangerous
It depends what you mean by "most dangerous". The bacterial species that causes the greatest numbers of deaths worldwide is probably mycobaterium tuberculosis, but that's largely a consequence of inadequate access to treatment in many parts of the world - although multidrug resistant TB is a growing problem. While Streptococcus has a relatively low fatality rare (with treatment), given the enormous number of Streptococcal infections, it leads to an enormous number of deaths as well. And Yersinia pestis was responsible for the Black Death, in which 100 million+ people were killed. If we consider species subtypes with specific antibiotic resistance patterns as separate options, then I would be particularly concerned to discover a patient was infected with VRSA (vancomycin resistent staph aurues), though luckily, this is profoundly rare. Probably the two bacterial infections that are routinely encountered in American hospitals that most worry me to find in a patient are MRSA bacteremia and acinetobacter pneumonia in patients on mechanical ventilators.

thank you for the lecture, very good as a means of repetition, however I could not help but notice that you left out som very important types of bacteria, Like Spirochetes, campylobacter, helicobacter and Mycobacteria, among others, was this intentional?
did i find this useful? Yes my friend, very. I done horribly in my mid terms on the microbiology part of one module... this is great to get to grips with the basics :)
That's a great question. Spirochaetes are in their own category not listed here. From a clinical standpoint, spirochaetes are as different to the categories I've described (e.g. gram positives, gram negatives, anaerobes, atypicals), as they are from one another. I didn't include them, or mycobacteria, here because this particular video series is focused on acute bacterial illness, and both spirochaetes and mycobacteria are more likely to cause subacute and chronic illnesses. I hope to cover both of them in their own video series at some point in the future.
+Eric's Medical Lectures I was going to ask about Mycobacteria and Spirochaetes too, maybe you could put this information on the description box. Thank you so much for all of your videos. Regards from Brazil.
Wonderful lecture. Thank you Dr. Strong. One question: how is it possible that the bacteria survive being flushed with alcohol or acetone during the gram test?
im a pharmacist i can confirm microbiology is absolutely the sort of thing that is included in your pharmacy education. along with a whole host of other areas- pharmacology, medicinal chemistry and drug design, human physiology and pathophysiology, physics and mathematics, pharmacy practice and law, health psychology and professional skills to name but a few- it is a very varied course! good luck!
This covered the whole class of microbiology. If detect B-hemolytic bacteria in mouth, do we need use medicine kill them? I remember my assignment in microbiology class was identification of unknown bacteria, my bacteria was gram negative, and I did again the next week because gram positive🧐. Then I got that one gram variable, I found in book this one gram negative when they are “baby”, gram positive when they “adult”. Are anatomy, physiology and microbiology can meet the biology requirements for med school ?
