luteo-caerulea, Onl J Vet
Res., 18(1): 7-11, 2014. In vitro antibacterial activity of different leaf extracts of
Scutellaria lute-caerulea
(Bornm. & Snit.) is reported. Ethanol, chloroform, ethylacetae
and aqueous leaf extracts were tested by the disc-diffusion method for activity
against common animal and human infectious bacteria. Pseudomonas aeruginosa
demonstrated the highest sensitivity against the extracts with a 10-15 mm zone
of inhibition. Polar fractions of ethanol and aqueous leaf extracts inhibited Staphylococcus
haemolyticus, S. aureus and Pseudomonas
but not Micrococcus luteus, Salmonella paratyphi
C, Xanthomonas maltophilia,
Enterobacter cloaca, Staphylococcus saprophyticus,
Micrococcus roseus, Hafnia alvei, Edwardsiella tarda,
Proteus mirabilis, Enterococcus faecalis
or Streptoccus pesomonie.
