单词 | anaerobic bacteria |
释义 | Anaerobic bacteriaanaerobic bacteriaBacteria which grow without O2, either by metabolic necessity (obligate anaerobes) or by preference (facultative anaerobes). Anaerobes are the primary pathogens of wound infections. Specimens obtained from patients in whom an anaerobic infection is suspected require special handling, as O2 (i.e., open air) is toxic to cultures and they may present as “culture-negative” if exposed; once the specimen arrives in the lab, it is processed under conditions of decreased O2, and any bacteria identified are recultured to determine their sensitivity to antibiotics.Anaerobic bacteriaan·aer·ob·ic bac·te·ri·a(anār-ōbik bak-tērē-ă) |
