Objective:
Prevalence of diseases originated from air pollution such as asthma and allergies, which is caused by pathogenic bacteria,
is the main reason for transmitting of the bioaerosols. Bacteria and fungi are the main sources of hospital infections, which cause
the most diseases and mortality. The aim of this study was to determine antimicrobial activity of the ethanolic extract of
Oliveria
decumbens leaf against five bacterial strains such as
Staphylococcus aureus
,
Entrococcus faecalis
,
Escherichia coli
,
Klebsiella pneumonia
and
Pseudomonas aeruginosa
and three candida species such as
Candida albicans
,
C. glarate
and
C. tropicalis
derivative from the
infected environment of hospital in southeastern of Iran.
Methods:
Selected Plant extract was prepared by using maceration. Minimum inhibitory concentration of extracts was determined
by well diffusion agar method.
Results:
The ethanolic extracts of
Oliveria decumbens
leaf was found to be moderate antimicrobial potential, but it was the highest
antimicrobial activity against Staphylococcus aureus with minimal inhibitory concentration (MIC) 1.25 mg ml-1. Also, it was active
against Candida spp. with MIC 2.5-5.0 mg ml-1.
Conclusion:
It was observed the ethanolic extracts of
Oliveria decumbens
leaf could be a potential bioactive agent as detergent for the
inhibition of growth of microbial environmental specially soil microbes.
