Determinazione della minima concentrazione inibente (MCI) dell'associazione trimetroprim/sulfadimetossina nei confronti di batteri patogeni per il suino [In vitro susceptibility of various bacteria to trimethoprim plus sulfadimethoxine for pigs in It
Società Italiana di Patologia ed Allevamento dei Suini - Proceedings, 2006, 335-338
The minimum inhibitory concentration (MIC) of the association trimethoprim-sulfadimethoxine (1:5) was determined for 52 bacterial strains recently isolated from Italian diseased pigs. This study included 13 strains of Actinobacillus pleuropneumoniae, 8 strains of Bordetella bronchiseptica, 5 strains of Haemophilus parasuis, 6 strains of Pasteurella multocida, 5 strains of Streptococcus suis, 8 strains of Escherichia coli K88+ and 7 strains of Salmonella spp. Great part of the tested strains (44/52), among which all strains of Bordetella bronchiseptican, Pasteurella multocida and Streptococcus suis, had a MIC <2/10mg/ml and thus are to be considered as susceptible to the association trimethoprim-sulfadimethoxine. Such antibiotic association remains a reliable treatment for pathologies due to bacteria in swine and should be applied following previous in vitro susceptibility tests.
