abstract:
The antimicrobial activity of tetracyc line hydrochloride (OTC) and cinnamon ( Cinnamomum zeylanicum Nees) essential oil (CEO)
was evaluated against six different isolates of Paenibacillus larvae (White), the causal agent of Am erican Foulbrood (AFB) disease
in honey bee colonies. The bacteria isolates were collected from different localit ies of Argentine. Minimal inhibitory concentration
(MIC) in MYT broth by the tube dilution method was evaluated fo r each substance and for the combinations of both antimicrobials
using Krogstad and Moellering technique in order to establish the possible synergistic effects between these substances. OTC me an
MIC values were of 3.67 ± 1.80 µg/ml, while the mean MIC values obtained for CEO were of 41.67±19.17 µg/ml. An inhibitory
synergetic effect between these substances was observed with FIC index < 1 on 50% of the on P. larvae isolates.
