n this study, we investigated the effects of P. guajava
on organisms responsible for skin disorders, specifically
the fungi:
Microsporum gypseum
and
Trichophyton
mentagrophytes
, and bacteria:
Staphylococcus aureus
,
and
Staphylococcus epidermidis
. The leaves and bark of
the P. guajava plant was harvested from Obasa farm Ijero,
Ekiti-State, Nigeria, during the beginning of rainy season in
March, 2009. Aqueous solutions were obtained by grinding
the leaves and the bark. Mueller-Hinton agar was used to
grow the bacteria S. aureus and S. epidermidis. Sabouraud
Dextrose broth was used to grow the fungi
Trichophyton
mentagrophytes
and
Microsporum gypseum
. Analysis of the
antibacterial action of the extracts of guava leaves and bark
was carried out at different concentrations, by comparing
the mean diameter of the inhibition haloes as a variable.
Values were represented as mean ± S.E. An ANOVA Tukey’s
test was performed to determine the mean difference
between the control and the two treatments (S1 and S2). In
comparing the tetracycline positive control to both solutions,
tetracycline had a significantly (p<0.05) stronger inhibition
effect than both solutions. This could be due to the fact that
tetracycline is a pure chemical while the P. guajava solutions
were crude extracts. Both
P. guajava
solutions were effective
against inhibiting the growth of bacteria
S. aureus
and
S.
epidermidis
, and fungi
M. gypseum
and
T. mentagrophytes
.
This supports the reported use of P. guajava in many
countries as a traditional herbal medicine.
