In vitro antimicrobial activity of water extract of Eucalyptus globules against Streptococcus bovis and Salmonella typhimurium

Introduction: The Tasmanian Blue Gum,Southern Blue Gum or Blue Gum,(Eucalyptus globulus)is an evergreen tree,one of the most widely cultivated trees native to Australia. They typically grow from 30 to 55 m (98 to 180 ft) tall. The tallest currently known specimen in Tasmania is 90.7m tall.There are historical claims of even taller trees,the tallest being 101 m (330 ft).The natural distribution of the species includes Tasmania and southern Victoria (particularly the Otway Ranges and southern Gippsland). Method and material: 100 g of dried plant material in 250 cc distilled water for 48 to 72 hours at 20 to 30 ° C and then placed over the duration of pressing the dry matter in water and wash with 50 cc distilled water remains liquid herbal extracts 50 percent. The antimicrobial activity of Extracts was determined by the disc diffusion method. Susceptibility tests were performed by the disc diffusion method of Bauer et al with Mueller Hinton agar. Results and Conclusion: The antimicrobial activity of Eucalyptus globules Extracts was assayed in vitro by agar disc diffusion method against streptococcus bovis and salmonella typhimurium. Aqueous extracts of Eucalyptus globules exhibited fair antimicrobial activity against streptococcus bovis and salmonella typhimurium. Zone of inhibition was streptococcus bovis 7mm and salmonella typhimurium negative. Topical ointments containing eucalyptus oil have been used in traditional Aboriginal medicines to heal wounds and fungal infections. Teas containing eucalyptus leaves were also used to reduce fevers. The therapeutic uses of eucalyptus soon spread to other traditional medicine systems, including Chinese, Indian (Ayurvedic), and Greco-European
