Cultivation of the smooth colony Mycobacterium abscessus
at the sub-minimum inhibitory concentration (MIC) of amikacin
changed its growth pattern including its colony morphology
(smooth to rough) and cell arrangement (dispersed
to cord formation). In addition, reduced sliding motility and
biofilm formation were observed. The amount of glycogpetidolipid
(GPL) and mRNA expression of key genes involved
in GPL synthesis were decreased in the amikacin-treated M.
abscessus strain. An in vitro infection assay revealed that the
amikacin-treated smooth M. abscessus strain induced more
pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) than that
of the smooth strain in murine macrophage cells. These results
suggest that long-term exposure to a low concentration of
amikacin causes a physical change in the cell wall which may
increase its virulence.

Epilepsy constitutes a significant public health problem, and even the newest drugs and neurosurgical techniques have proven unable to cure the disease. In order to select a group of isolates which could generate an active compound with neuroprotective or antiepileptic properties, we isolated 517 actinomycete strains from soil samples taken from Jeju Island, in South Korea. We then screened these strains for possible anti-apoptotic effects against serum deprivation-induced hippocampal cell death, using the 3-(4, 5-dimethylthiazol-2-yl)2,5-diphenyl-tetrazolium bromide (MTT) assay as an in vitro test. The excitotoxic glutamate analog, kainic acid (KA), was used to induce seizures in experimental mice in our in vivo tests. As a result of this testing, we located one strain which exhibited profound neuroprotective activity. This strain was identified as a Streptomyces species, and exhibited the rifampin-resistant genotype, Asn(AAC)^442, according to the results of 16S rRNA and rpoB gene analyses
