Of the 18 types presently recognized for the genus Brucella, 11 were identified within the sample. In animal strains, they were B. abortus biotypes 1, 2, 3, 4 and 9, B. suis biotypes 1 and 2, B. melitensis biotypes 1, 2 and 3, and B. ovis. All these types--except B. suis 2 and B. ovis--were identified within the human strains. Of these 11 types, 3 were widely predominant both in man and animals: B. abortus biotypes 1 and 3 and B. melitensis biotype 3, which together total 84.2% of the sample's strains. The results also emphasized the preference of B. abortus, B. melitensis and B. ovis for a decided animal host: 99.4% of the bovine strains were B. abortus, 98.1% of those isolated from ewes and goats were B. melitensis, and all the B ovis strains were from cases of ram epididymitis.

Synergy was evaluated by the reduction of the beta-lactam agar dilution MIC and by the measurement of intracellular AYP using firefly bioluminescence. The potentiation effect of clavulanic acid was variable, depending on resistance levels, species and types of beta-lactamase (TEM, SHV-1, CARB, OXA, MAL and Cpase). The synergy was significant, with 10 mg/l of inhibitor for all the strains producing TEM-1, TEM-2 and Carb-2 except for one strain of Serratia marcescens (TEM-2). The synergy was weak for Levinea strains (Citrobacter diversus biotype b), biosynthesizing specific penicillinases as MAL-1. No potentiation effect was observed for strains producing a cephalosporinase, such as Escherichia coli and Pseudomonas aeruginosa. This effect appeared to be variable for strains producing the oxacillin-hydrolysing enzyme (OXA-1), such as E. coli and P. aeruginosa. A positive correlation was clearly demonstrated between the MIC values and the intracellular ATP concentration in bacteria within 2 h.
