The present paper describes and discusses the antibacterial potential of the Himalayan Orchids with reference to the nine species namely Aerides multiflora Roxb.,Crepidium acuminatum (D.Don) Szalch., Dendrobium amoenum Wall. ex Lindl., Flickingeria macraei (Lindl.) Seidenf., Habenaria intermedia D.Don, Pholidota articulata Lindl., Rhynchostylis retusa (L.) Blume, Smitinandia micrantha (Lindl.) Holttum, and Vanda testacea (Lindl.) Rchb.f. These orchids were also screened for their alkaloid test. Also, the test microorganisms (bacterialspecies) Bacillus subtilis, Bacillus megaterium, Escherichia coli, Klebsiella pneumoniae, Micrococcus luteus, Salmonella typhi, and Staphylococcus aureus are described for their biochemical, cultural characteristics, and pathogenicity.
