AB A total of 30 British and 30 Spanish Haemophilus parasuis isolates were testedfor their susceptibility to 19 of the antimicrobials currently used in swine practice with abroth microdilution method in order to know the emergence of resistance against thesecompounds in this porcine pathogen. All the British isolates were susceptible to penicillin,ceftiofur, erythromycin, tilmicosin, enrofloxacin, and florfenicol, and most of them weresusceptible to the remaining antimicrobials (the highest resistance rate found was of 20%to neomycin). In contrast, all the Spanish isolates were susceptible exclusively toflorfenicol, and high proportions of resistance were encountered for penicillin, ampicillin,oxytetracycline, erythromycin, tilmicosin, tiamulin and trimethoprim +sulphamethoxazole; in addition, a bimodal or multimodal distribution, or tailing of Spanishisolates over the MIC range was observed for clindamycin, sulphonamides and tylosinetartrate, suggesting the development of acquired resistance. In addition, several multiresistance patterns were found among the Spanish isolates, 23.3% of them beingresistant to at least eight antimicrobials, the same rate as that encountered for those beingsusceptible to all antimicrobials tested. This study showed that in general British H.parasuis isolates are susceptible to antimicrobial agents routinely used for treatment ofporcine respiratory diseases; however, the Spanish isolates need a more continuoussurveillance of their susceptibility patterns
