  • The previously described pathophysiology of nocardiosis cannot be confirmed. Antibiotic susceptibility of N. cyriacigeorgica showed the usual in vitro effectiveness of cotrimoxazole, imipenem, amikacin and linezolid, but also minocycline [ 3 ].[err.ersjournals.com]
  • As new and more powerful immunosuppressive drugs became available, 6 the epidemiological, pathophysiological, and clinical characteristics of opportunistic infections might have changed.[journals.lww.com]
  • Pathophysiology Nocardia species are facultative intracellular pathogens that gain virulence through evading the host's immune responses.[dermatologyadvisor.com]
