Atypical Mycobacterial Lymphadenitis
Bacterial lymphadenitis is the result of infection by nontuberculous mycobacteria (NTM). Nontuberculous (also known as atypical) Mycobacteria species are ubiquitous noncommunicable opportunistic pathogens that cause disease primarily in immunocompromised individuals. Infections have been associated with human immunodeficiency virus (HIV) and iatrogenic immunosuppression. The bacilli are acid-fast, like Mycobacterium tuberculosis, but they exhibit different characteristics in cell culture. The most common NTM species associated with lymphadenitis are listed in Table 7.1.
