The types of bugs that have been found in sarcoid granuloma (so far) are a special type of bug. They live inside cells. Many antibiotics have difficulty penetrating the cell wall (epithelium). The tetracycline family does it well, and the three variants (tetracycline, minocycline and doxycycline) each work in a slightly different way. That is why sometimes one will be more effective than another.
Choosing the correct antibiotic really is a science. Click here to read an article about how researchers found which antibiotics work best against the Rockettsia Felis, another cell-living bug that is spreading here on the West Coast. They used DNA techniques to find it was susceptible to "doxycycline, rifampin, thiamphenicol, and fluoroquinolones but not to gentamicin, erythromycin, amoxicillin, or trimethoprim-sulfamethoxazole (Bactrim)."
The chart in the complete article shows that doxycycline worked best of all, the other drugs were less effective, but still did the job reasonably well. The researchers did not test Minocycline.
The researchers planning the cardiac study had chosen the antiobiotics amoxicillin, metronidazole, azithromycin, metronidazole, and omeprazole. Combinations of antibiotics (as used in this study) are often more effective than individual drugs because they each can simultaneously target different stages of the organism's life cycle.
But the bacteria that these researchers had expected were not actually found in the patients! Nevertheless, whatever bugs were causing the problem, and they may have been different in each patient, they reacted well enough (to just a one week course of them) so that 36% of the patients were spared more serious cardiac illness. That is an amazing success rate for such a simple course of therapy!

ps: I have seen no data on how Keflex (Cephalexin) works against cell-living organisms. Don't use it for this purpose. It is usually used to attack: S. pneumoniae, H. influenzae, staphylococci, streptococci, and M. catarrhalis
