The plant extracts clearly demonstrate antibacterial properties, although the mechanistic processes are poorly understood these activities suggest potential use as chemotherapeutic agents, food preserving agents and disinfectants. The plant extracts were tested on mueller hinton ii plates to detect the presence of antibacterial activity prior to streaking the plates with bacteria, 5 mm diameter wells were punched into the medium using a sterile borer. Antibacterial and antifungal activities of plant part extracts against four pathogenic bacteria (two gram-positive and negative) and three pathogenic fungi were investigated by the agar disk diffusion method[29–31] antimicrobial activity testing was carried out by using agar cup method each purified extracts were dissolved in dimethyl sulfoxide, sterilized by filtration using sintered glass filter, and stored at 4°c.
Clinical microbiologists have two reasons to be interested in the topic of antimicrobial plant extracts first, it is very likely that these phytochemicals will find their way into the arsenal of antimicrobial drugs prescribed by physicians several are already being tested in humans (see below) brantner a, grein e antibacterial activity. Keywords: urinary tract infection (uti), multidrug resistant, antibacterial activity, indian medicinal plants plant parts were collected on the basis of the information provided in the ethanobotanical survey of india and local medicine men of mahakoshal region (mp), india each specimen/plant.
It is expected that plant extracts showing target sites other than those used by antibiotics will be active against drug resistant pathogens 11 medicinal plants have been used as traditional treatments for numerous human diseases for test for antibacterial activity. Key words: medicinal plants, traditional uses, phytochemical effects, antimicrobial activity introduction medicinal plants are abundant source of antimicrobial molecules a wide range of medicinal plants extracts are used to treat several infections as they have potential antimicrobial activity. Academia journal of microbiology research uddin 023 table 1 antibacterial activity of plant extracts of 34 species by disc diffusion method.
Field of ethanopharmacology the antibacterial activity of medicinal plants produced 115 articles from the period between 1966 and 1994however, in the following decade between 1995 and 2004, this number more than doubled, to 307 in these studies one finds a wide range of criteria related to the discovery of antimicrobial compounds in plants. Antibacterial activity of plant extracts of 22 species by agar cup method o family/species (100µl/cup crude extract) parts used test organism zone of inhibition in diameter (mm) se e i rae us r25 1 alstonia scholaris leaf - - - - r66 2r moringa olifera root - - - .
Antibacterial activity of plant extracts against enterococcus faecalis acknowledgments the authors are thankful to head, department of post graduate studies and research in biological sciences, r d university, jabalpur, india for providing laboratory facilities. Yarrow extracts did not present any antimicrobial activity association of antibiotics and plant extracts showed synergistic antibacterial activity against antibiotic-resistant bacteria the results obtained with pseudomonas aeruginosa was particularly interesting, since it was inhibited by clove, jambolan, pomegranate and thyme extracts.
Extracts, and all the plant extracts demonstrated scavenging power against dpphthe cytotoxicity of extracts of garcinia livingstonei , and sclerocarya birrea barks ranged between 1059 µg/ml and 7699 µg/ml.
The extract of santalum album showed maximum antibacterial activity of the 10 plant extracts used bacillus cereus and pasteurella multocida were the most sensitive bacteria.
