Streptomyces sp. myrophorea
"Streptomyces" sp. myrophorea, isolate McG1 is a species of "Streptomyces", that originates from a (ethnopharmacology) folk cure in the townland of Toneel North in Boho, County Fermanagh. This area was previously occupied by the Druids (~1500 years ago) and before this neolithic people (~ 3,700 years ago) who engraved the nearby Reyfad stones. "Streptomyces" sp. myrophorea is inhibitory to many species of ESKAPE pathogens, can grow at high pH (10.5) and can tolerate relatively high levels of radioactivity. Physiology and morphology. "Streptomyces" sp. myrophorea isolate McG1 has light green to white spores and hyphae when cultivated on  SFM agar. The colonies of "Streptomyces" sp. myrophorea have a distinctly dusty appearance and produce an aroma similar to germaline on maturation. This bacteria produces many spores, approximately 0.5-1.0 micrometers in width which form in straight chains. Ecology. "Streptomyces" sp. myrophorea isolate McG1 was discovered in an alkaline, species rich environment. This bacteria grows at a maximum pH of 10.5, and is therefore alkaliphilic. The bacteria tolerate higher levels of alkalinity but do not thrive. "Streptomyces" sp. myrophorea can also withstand relatively high levels of radiation (up to 4kGy. This may be related to the underlying limestone and shale  substrata which emits radon gas. Antibiotic production. Only antibiotic gene synthesis clusters have been identified in "Streptomyces" sp. myrophorea; the antibiotics actually produced in-situ have yet to be identified. "Streptomyces" sp. McG1 is broadly inhibitory to both Gram positive and Gram negative bacteria including carbapenem resistant Acinetobacter baumannii, (a critical pathogen on the World Health Organization priority pathogens list), vancomycin resistant Enterococcus faecium, methicillin resistant Staphylococcus aureus (listed as high priority) and Klebsiella pneumoniae. Streptomyces sp. myrophorea has limited effects against strains of Enterococcus faecium and Pseudomonas aeruginosa. Alkaline tolerance. "Streptomyces" sp. myrophorea may be able to flourish in  an alkaline environment because it contains many genes similar to those associated with alkaline tolerance in other bacterial species. "Streptomyces" sp. myrophorea list of alkaline tolerance genes: In-vitro antibiotic resistance. The presence of antibiotic resistance genes is often linked to the production of antibiotics. "Stretpomyces" sp. myrophorea has been recorded to be resistant to 28 antibiotics and sensitive to eight antibiotics in one series of tests. The antibiotics were tested at breakpoint concentrations recommended by The European Committee on Antimicrobial Susceptibility Testing - EUCAST, to test antimicrobial susceptibility. Antibiotic sensitivity of "Streptomyces" sp. myrophorea: Sensitivities recorded as: Sensitivite (S), Resistant  (R) or Intermediate (I). Whole genome sequencing.
