omnicef/Cefdinir is very good against
PERSISTENT borrelia. Sorry the caps but i want this to be clear.
"Using our HTS method, we were also able to identify some cephalosporins that were very active against the persistent forms of Borrelia.
Cephalothin, cefdinir, cefotaxime acid, and ceftazidime had a bacterial inhibition value of >98%. Cephalosporins follow a mechanism similar to penicillins for demonstrating their antibacterial effects. However, these drugs are more resistant to the action of β-lactamases. Cephalothin, cefotaxime acid, and ceftazidime are the first-and third-generation parenteral cephalosporins. Cefdinir, however, is a third-generation oral cephalosporin having up to 25% bioavailability.60 A number of cephalosporins have been proved to possess remarkable activity against a number of bacteria, including B. burgdorferi.35"
/www.ncbi.nlm.nih.gov/pmc/articles/PMC4827596/it is very important to take 3 antibiotics not just two or one and Cefdinir is among the most effective persister drug out there, as you can see from the mentioned study.
Girlie said...
The penicillins and cephalosporins (Ceftin) work to weaken the spirochete outer covering.
yes Girlie but it's a trick, some cephalosporines as this Omnicef, they destroy persisters. They do this because the Borrelia persisters are weird. They are not dormant cysts. The peptidoglycan (component of cell wall)
continues to be manufactured inside the lyme "cysts". Nobody really knows why is this, are these "persisters" replicating ? Maybe, maybe not... but still the machinery of cell wall synthesis continues inside the cell, which means the normal penicilin family works against them. Of course you need third generation cephalosporines and more advanced penicilin antibiotics, not just amoxicilin, these newer penicilins are getting deeper into tissues and probably get into the cells.
Let's see what K Lewis had to say in this game changing paper that we now have full access:
aac.asm.org/content/59/8/4616.full"Cell wall-acting antibiotics do not normally kill nongrowing cells; one possibility is that stationary state B. burgdorferi cultures represent a steady state of growing and dying cells. The ability of β-lactams to kill nongrowing cells was also observed in M. tuberculosis where a combination of mer
openem and a β-lactamase inhibitor was able to kill viable but nonreplicative cells (50).
The authors speculate that peptidoglycan remodeling continues in these nonreplicating cells allowing for the activity of the β-lactam. This is another possible explanation of the killing of stationary-phase B. burgdorferi that we observed with amoxicillin and ceftriaxone."So let's not treat these as simple cell wall drugs... It is IMPORTANT to take this antibiotic, along with the other two, so 3 antibiotics, to kill the persisters.
