RESULTS
A total number of Eighteen (18) samples were
collected from patient suffering from ocular infections.
Four (4) bacteria species were identified, they includes
Staphylococcus aureus, Escherichia coli, Streptococcus
pyogene, Streptococcus pneumonia. Table 1 indicated
the percentage frequency of occurrence. From the result
obtained, Escherichia coli has the highest percentage
frequency of (33.3) followed by Staphylococcus aureus
and Streptococcus pneumonia with (26.7%) while
Streptococcus pyogenes had the lowest with (13.3)
percentage frequency. Table 2 showed the antibiotic
sensitivity test of bacterial isolates. From the result
obtained, all the organisms were sensitive to
ciprofloxacin, Streptococcus pyogenes was highly
sensitive with 20mm followed by Staphylococcus
aureus with 19 mm then Escherichia coli and
Streptococcus pneumonia were less sensitive with
17mm. Table 3 showed the antagonistic action of the
onion extracts. The cold water onion extract exerted no
inhibitory effects on the bacterial isolates. However,
Streptococcus pyogenes and Staphylococcus aureus
were sensitive to the fresh onion extracts with the zone
of inhibition ranging from 17mm in Staphylococcus
aureus to 20mm in Streptococcus pyogenes. Moreover,
Escherichia coli was sensitive to fresh onion extracts
with the zone of inhibition of 15mm in diameter and
Streptococcus pneumonia had a zone of inhibition of
8mm on fresh onion extracts. Table 4 showed the
minimum inhibitory concentration of the fresh onion
extracts for bacterial isolates from ocular infection.
Fresh onion extracts inhibited the growth of the
organism at 100% concentration and all the organisms
grow at the lowest concentration of the fresh onion
extracts.
