Résumé:
Objective:
O
ur investigation is about the determination of the antibacterial efficiency of
22
medicinal plants on the four most frequent bacteria in urinary infections.
T
hese infections are
responsible for more than
15
%
of urinary stones formation.
Methods:
W
e have initiated an
extraction liquid/solid.
I
n this respect, we have used water extractions according to the standard
methods utilized by the local populati
on, i.e:
(
i
)
the d
é
coction,
(
ii
)
the infusion,
(
iii
)
the mac
é
ration
and
(
iiii
)
the percolation.
T
he microorganisms used are
Staphylooccus aureus
,
Escherichia coli,
Proteus mirabilis
and
Pseudomonas aeruginosa
.
T
he strains were isolated from patients having
urinary infections.
T
he antibiotic disks
K
anamicin,
C
olistin,
A
moxicillin,
G
entamicin,
A
mpicillin
were applied to the reference bacteria at concentrations of
30
毺
g,
50
毺
g,
25
毺
g,
10
毺
g et
10
毺
g respectively.
Results:
T
hese stu
dies showed that decoction
(
d
)
had the higher effect with
43
.
3
%
followed by percolation
(
p
)
(
28
.
3
%
)
and maceration
(
m
)
(
16
.
7
%
)
.
I
nfusion
(
i
)
had a limited effect
(
11
.
7
%
)
.
Escherichia coli (E.coli)
,
Proteus mirabilis
,
Staphylococcus aureus
showed
an aver age
sensitivity of
28
%
in each case.
H
owever,
Pseudomonas aeruginosa,
a highly pathogenic and
resistant bacteria showed up to
17
.
5
%
of sensitivity.
16
.
3
%
of the plant extracts showed a high
antimicrobial activity.
Pseudomonas aeruginosa
was highly resi
stant to
K
anamycin,
A
moxicillin
and
A
mpicillin and at a lower extent to
C
olistin and
G
entamicin.
H
owever, it was sensitive to
some plant extracts such as
Allium sativum, Artemesia compestris(p,m), Citrus aurantium(p),
Cotula cinerea(p), Lavandula officinalis (d) , Globularia alypum (d) , Juniperus phoeniceae (m) ,
Olea europaea (p), Pistacia lentiscus (m) , Trachyspermum ammi (m), Zygophyllum album (p)
and
Zingiber officinalis (d).
Conclusion:
T
he present work shows that most of the studied plants
are potentially a good source of antimicrobial agents and it proves the importance of such plants
in urolithiasis medicine and alternative healthcare.
