Figure 2. Day zero, five, seven, a comparison of mean estimated bacterial count (CFU/mL) between beef
soup test tubes containing 0.1 mL Salmonella, 0.1 mL garlic solution with 0.1mL Salmonella, 1.0mL garlic
solution with 0.1mL Salmonella, and 10.0 mL garlic solution with 0.1mL Salmonella. Error bars indicate
standard error.
Day zero’s mean estimated bacterial count
for beef soup test tube containing 0.1 mL Salmonella
was 10,438,271,550 ± 794,533,710.4 CFU/mL (n=5,
Mean ± S.E.M.). Mean estimated bacterial count for
beef soup test tube containing 0.1 mL garlic solution
with 0.1 mL Salmonella was 3,996,336,488 ±
312,731,818.2 CFU/mL (n=5, Mean ± S.E.M.). Mean
estimated bacterial count for beef soup test tube
containing 1.0 mL garlic solution with 0.1 mL
Salmonella was 419,523,300 ± 62,306,189.52
CFU/mL (n=5, Mean ± S.E.M.). Mean estimated
bacterial count for beef soup test tube containing 10.0
mL garlic solution with 0.1 mL Salmonella was
24,430 ± 9,964.033445 CFU/mL (n=5, Mean ±
S.E.M.). ANOVA (p=0.0001) and bonferroni post
test indicated that there were significant differences
between each beef soup test tube group.
Day five’s mean estimated bacterial count
for beef soup test tube containing 0.1 mL Salmonella
was 12,011,781,600 ± 1,311,965,380 CFU/mL (n=5,
Mean ± S.E.M.). Mean estimated bacterial count for
beef soup test tube containing 0.1 mL garlic solution
with 0.1 mL Salmonella was 3,218,362,875 ±
307,489,403.8 CFU/mL (n=5, Mean ± S.E.M.). Mean
estimated bacterial count for beef soup test tube
containing 1.0 mL garlic solution with 0.1 mL
Salmonella was 138,418,875 ± 32,379,901.34
CFU/mL (n=5, Mean ± S.E.M.). Mean estimated
bacterial count for beef soup test tube containing 10.0
mL garlic solution with 0.1 mL Salmonella was 210
± 169.668795 CFU/mL (n=5, Mean ± S.E.M.).
ANOVA (p=0.0001) and bonferroni post test
indicated that there were significant differences
between each beef soup test tube group.
Day seven’s mean estimated bacterial count
for beef soup test tube containing 0.1 mL Salmonella
was 13,767,518,363 ± 431,414,168.2 CFU/mL (n=5,
Mean ± S.E.M.). Mean estimated bacterial count for
beef soup test tube containing 0.1 mL garlic solution
with 0.1 mL Salmonella was 3,128,117,738 ±
477,471,563.5 CFU/mL (n=5, Mean ± S.E.M.). Mean
estimated bacterial count for beef soup test tube
containing 1.0 mL garlic solution with 0.1 mL
Salmonella was 108,552,150 ± 10,014,661.33
CFU/mL (n=5, Mean ± S.E.M.). Mean estimated
bacterial count for beef soup test tube containing 10.0
mL garlic solution with 0.1 mL Salmonella was 0 ± 0
CFU/mL (n=5, Mean ± S.E.M.). ANOVA (p=0.0001)
and bonferroni post test indicated that there were
significant differences between each beef soup test
tube group.
ANOVA (p=0.073) indicated that there were
no significant differences between each day of
