I'm studying biochemistry and actually did my bachelor thesis about isoniazid resistance in tuberculosis. It might actually get published soon! :D

That's awesome! I am familiar with isoniazid as a serendipitous (as all the pathbreaking discoveries were until recently) discovery in psychopharmacology. IIRC, it was abandoned in favor of iproniazid, which was, in turn, abandoned in favor of isocarboxazid. Unfortunately, I only ever took one chemistry course in high school, so I don't understand much about the physicochemical aspects of all of this. Have you ever read a detailed account of the discovery of its antidepressant efficacy? It's an interesting story. I was wondering if you could briefly explain what it is about these drugs antibiotic effect especially effective for Tuberculosis, as I have never understood it. Hydrazine drugs are interesting to me because they have so many different effects. You can use phenelzine for many different conditions; it is also an inhibitor of SSAO, and its major metabolite, phenethylhydrazine, is a potent inhibitor of GABA-T and could be used as a GABAnergic drug in its own right. It probably should be, actually, as it is so much less toxic than vigabatrin. But I digress. Cheers!

@@ashiammi33351 Hi, i'm assuming you mean how this gets tested in the lab? They basically take a swab and try to grow it in a culture where multiple drugs at certain concentrations are added. There are defined thresholds set by WHO. If the sample manages to grow, it means it is multidrug resistant. They are also working on using genetic screening to predict the resistance level of a certain strain, but the culture method remains the golden standard for now.

This video is quite accurate, good job on it. I would add, because I think its important to why TB remains such a problem even to this day, that the current drug regimin the antibiotic course is 6-9 months long AND the drugs make you nauseous. This can obviously cause major issues with compliance. It is difficult enough to get someone in a developed nation to take just a full course of 7 days of antibiotics....imagine trying to get people in poor areas or underdeveloped areas of the world to commit to 9 months of a 2-4 drug cocktail (4 drugs for 2 months, then 2 of those for 4-7 additional months) that makes them feel terrible and lethargic.

Mdr tb might transmit to people around you while talking,coughing, laughing etc. I hope you'd take great care. Wear a mask around people and stay in a well ventilated room. Also,have a healthy diet. It would help you to recover soon and will help your body to response to the medicine. I hope you get well soon. Take care.
