Preliminary antibacterial testing of mushroom methanolic extracts through determination of the zone of inhibition (mm ±SD).

Isolates	Mushroom extracts		Standard drug
	P. ostreatus	P. florida	Streptomycin
Esherichia coli	14 ± 0.2	17 ± 0.2	24 ± 0.2
Bascillus subtilis	13.5 ± 0.1	16 ± 0.2	25 ± 0.2
Streptococcus faecalis	13.4 ± 0.1	14 ± 0.1	25 ± 0.2
Pseudomonas aeruginosa	7 ± 0.2	12 ± 0.2	20 ± 0.1
Salmonella typhi	11.5 ± 0.3	15 ± 0.1	20 ± 0.1

The diameters of the zone of inhibition are expressed in millimeter (mm) as mean ± standard deviation (SD).
