In Vitro Antibacterial Spectrum of Sodium Selenite against Selected Human Pathogenic Bacterial Strains

Table 1

Antibacterial effect of sodium selenite against selected human pathogenic bacteria.

Organisms	Zone of inhibition (mm) ± SEM
	Sodium selenite (1% w/v)	Ciprofloxacin (5 mcg/disc)
Streptococcus pyogenes	15.5 ± 0.84	28 ± 2.6
Staphylococcus aureus	24 ± 0.73	26 ± 1.2
Bacillus subtilis	25.66 ± 0.49	24 ± 1.4
Escherichia coli	21.83 ± 0.47	21 ± 2.6
Pseudomonas aeruginosa	18.83 ± 1.07	20 ± 0.2
Klebsiella planticola	26.33 ± 1.11	23.5 ± 1.4

Each value is the mean of batches with standard deviation; is extremely significant when compared to standard drug by performing the Tukey Kramer test (post hoc analysis).
