Cellwall is present in Rickettsial organisms

[@emeraldo4122]

They actually do lack a cell wall but they have a unique cell membrane made of lipopolysaccharides ... I hope this helps

I'm enjoying studying with the help of your videos😃and collecting pieces of information while watching your sketches & your wonderful effort to help us knowing the knowledge by heart easily👍very waiting with passion to solve the question at each episode end🥳but it has been long time since I'm thinking of another easier way instead of trying to know all the details of the sketches, in a way that connect all the data together briefly🤔I'll write you doen an example & hopefully you can offer us soon such way if you just liked it😁for example "Borrelia" why you are not using its letters writing or drawing it differently to inform us about the organism details just on mentioning the name or thinking how it's written with extra-minor details!😃for example the letter "l" of borrelia why you don't draw it as zegzag line, then you reming us it's a spirochete, while using the letter "O" to be the bull's eye drawing it like that🎯and yhe letter "B" reminds us with bell's palsy, also with bull's eye, using both curves of "B" to be the eyes👀but vertically with eyebrows as if it's shaking as cartoons💓then we remember the a-b block of the ht.causing arrhythmias, using also the big bellies of "B" to remind us of the pregnant women using amoxycillin instead of doxycyclin in ttt, double "rr" to remind us with the 2nd generation cephalosporin, the dot of "i" letter also can remind us with the bull's eye (a 3rd way to remember)😃while drawing the "i" dot horizontally as a dash "-" to remind us that it's gm -ve bacteria, using the zigzag line of "l" to remind us with the migratory arthritis of 3rd stage of c/p, you may wrote yhe zigzag with only 3 turns to remind us with the 3 stages of the c/p, using the "r" letter to remind us with an electric lamp💡at the end of the "r" to remind us with dark field microscopy, also "O" can help us remember the recurrent fevers with an arrow on the frame of "O" as it's done on downloading, dot of "i" also can remind us with flu-like symptoms😪making it blue dropping💧also putting "O" with sparkling surrounding remind us with Giemsa stain as if it's a gem💎or let it be yhe letter "a" also encephalitis🧠of 3rd stage of c/p is very similar to the letter "e" if you just put a mirror image to that brain photo, so as the spleen enlargement, and if you just add another mirror image of letter "B" then you get the figure "8" that remind us with our beloved tetracyclin used in ttt that it's contraindicated in children less than 8 years of age for fear of teeth staining, we can see in the zigzag "l" obviously😉afterall the baby in the cavity of "B" letter remind us of "dear" tick🤗writting the "B" in black color⚫remind us it's the black legged tick, so we get migratory arthritis (of legs) also in the 3rd stage🦵and so on, using colors of the letters, using their variable shapes in capital & small & other effects can add so much clear, funny & prominent details cann' t be missed, all by just writting the organism name😁and thanks for inspiring us with all the ways you offered to make our tough study kind of fun💐
