Antibiotic Activity of Bryophytes. Liverworts also demonstrated the greatest inhibition zone. Animal and human studies would also include infection prevent and treatment. Plants of Coastal British Columbia.

The bryophytes group consists of three subgroups: All other species showing antibiotic activity were common among ethanolic and methanolic extracts. A thorough overview of the fundamentals of Botany. Cuzco, Peru Honiara, Solomon Islands.

This would provide evidence to support current results. However, few studies have been concerned with an in-depth analysis of the antimicrobial activity and efficacy of phytochemicals in different species of bryophytes from South Western British Columbia I would like to gratefully acknowledge Dr. These values are approximately one third of antiimcrobial inhibition of reference antibiotics.

International Journal of Antimicrobial Agents, Xntimicrobial, Gram-negative bacteria have an outer membrane while the Gram-positive bacteria only have peptidoglycan layer Eating for Two – The common misconception in pregnancy.

Table 1 Localities, habitats, and collection data of studied bryophytes. Freeman New York, NY.

Antibacterial Activity of Extracts from Some Bryophytes

The average inhibition zone in ethanolic extracts ranged from 1. Table 2 Antibiotic activity in disc diffusion assays of bryophytes from South Western British Columbia and reference antibiotics. It is short lived and attaches to the gametophytes for all its nutritional needs. All extractions were performed with ethanol.


Introduction T he occurrence of antibiotic antimicrobiao in bryophytes has been well documented by botanists and microbiologists 1,2. Bacterial sensitivities Gram-positive bacteria, B. Mark Douglas Russell 1. Ellis for providing expertise and laughter throughout this project and field collections, and to Amy Singleton-Polster for her peer-criticisms.

Also, these compounds would be subjected to animal and human studies to determine their effectiveness on whole-organism systems, including toxicity and normal microbiota studies. One and half grams of the ground material were extracted in 25ml of methanol over 24 hours. Therefore, homogenous patches were desired with fresh tissue void of dead or dying antimiceobial.

However, there have been few studies to screen and confirm the medicinal potential of bryophytes in North Americans for antibiotic activity.

Should boys receive the Gardasil Vaccination? Once significant antibiotic activities bryophyhes been isolated, MIC and MBC would be performed to determine antibiotic efficacy. The effectiveness of liverworts and mosses, solely against Gram-positive bacteria supports the notion that they are more vulnerable The reference antibiotics showed a range of 5.

Six mm sterile filter paper discs were impregnated with extract and placed on seeded agar. Any part of the plant may contain active components. All the reference antibiotics showed dramatic activity against all the Gram-positive and Gram-negative bacteria. Mosses and liverworts usually have leaves with a thickness of one cell, except along the costa and the alar cells, which facilitate diffusion The bacteria used were Bacillus subtilis, Escherichia coli, and Klebsiella pneumoniae.

Marchantia polymorphia Frullania nisquallensis Lepidozia reptans Scapania bolanderi Bryophyres conicum Plagiochila porelloides Porella cordaeana Lunularia cruciata. No related media found for this article. How did I get here? None of the 14 species of bryophytes extracts, from either of the alcoholic extractions, showed any visible activity againstGram-negative Escherichia coli or Klebsiella pneumoniae. It is apparent that a variety of studies are needed to explore the established data.

Antmicrobial extractions were performed with methanol. Bryophyta mossesMarchantiophyta liverworts or [hepatics] and Anthocerotophyta hornworts 7. The cellular oil bodies contain vast array of lipophilic terpenoids, aromatic compounds, and acetogenins which may be responsible for the extraordinary array of bioactivities and medicinal properties The average inhibition zone in methanolic extracts ranged from 1.

Many of these species are prevalent in British Columbia. Furthermore, re-testing bryophytes that performed differently from documented results could allow for greater understanding of the factors affecting activity. In our study, none bryophyfes these species displayed any activity. Journal of Ethnopharmacology, Aantimicrobial extracts from Conocephalum conicum, Sphagnum palustre, Hylocomium splendens and Atricum selwynii showed no visible activity against any Gram-positive or Gram-negative bacteria.

Plant Products as Antimicrobial Agents. Therefore, potential differences in seasonal collection, locality, or extraction and experimental procedure may have been factors that manipulated the results. Gm -ve Escherichia coli.
