AB The comparative efficacy of 16 active compounds (including the most commonly used chemical groups) 19and 10 commercial formulations against Haemophilus parasuis serovars 1 and 5 was studied. These organ- 20isms were tested in suspension and carrier tests in the presence and absence of serum as representative 21of organic matter. Chloramine-T and half of the formulations from commercial sources (most of them 22including quaternary ammonium compounds) were effective in both in vitro tests, regardless of the pres- 23ence or absence of organic load. All 26 disinfectants except for an iodophor (0.1% available iodine) 24resulted in at least 3-log10 reduction in colony-forming units in suspension test, and most of them 25resulted in the maximal level of detection (>6-log10 reduction). On the other hand, disinfectants were 26not as effective in carrier test as in suspension test, and the presence of serum considerably reduced 27the activities of most of the compounds tested, especially in carrier test. These results suggest the impor- 28tance of selecting suitable disinfection for routine use on surfaces contaminated with H. parasuis, partic- 29ularly when organic matter is present. Chloramine-T and formulations 2 and 7–10 are recommended for a 30complete inactivation of H. parasuis in swine herds
