Mupirocin is inactive for most anaerobic bacteria, mycobacteria, mycoplasma, chlamydia, yeast and fungi. Aseptic meningitis is caused by viruses, mycobacteria, spirochetes, fungi, medications, and cancer malignancies. The major implicated infectious agents include&colon; mycobacteria, fungi, borrelia, and rickettsia. Other causes may include mycobacteria, fungi, spirochetes, and complications from HIV. It is thought that silica damages pulmonary macrophages, inhibiting their ability to kill mycobacteria. Selective media for mycobacteria or fungi can also be inoculated. BCG has protective effects against some non-tuberculosis mycobacteria. It can be caused by tuberculous or nontuberculous mycobacteria. Other bacterial causes of neonatal CAP include "Listeria monocytogenes" and a variety of mycobacteria. Phenotypic tests can be used to identify and distinguish different mycobacteria species and strains. Other known pathogenic mycobacteria include "M. leprae", "M. avium", and "M. kansasii". BCG also has some effectiveness against Buruli ulcer infection and other nontuberculous mycobacteria infections. The genomes of some mycobacteria are quite large when compared to other bacteria. Isoniazid is bactericidal to rapidly dividing mycobacteria, but is bacteriostatic if the mycobacteria are slow-growing. Bedaquiline blocks the proton pump for ATP synthase of mycobacteria.
