Abstract

The susceptibility of bacterial pahogens isolated from animals in Transylvania was tested through the disk diffusion method. The resistance to cephalosporins was registered for all examined pathogens, the highest percentage in genus Pseudomonas (100%) and Streptococcus (92.31%). Genus Corynebacterium and Klebsiella showed resistance in 75% and had intermediate strains of 25%; no strain was sensitive to cephalosporins. In staphylococci was found a lower resistance of 66.66%, compared with other gram-positive bacteria: streptococci, corynebacteria. Gram-negative bacteria were resistant ≤ 50%: Citrobacter, Enterobacter, Morganella 50%, Proteus 40%, Escherichia coli 37.5% and Pasteurella 33.33%. The highest sensitivity to cephalosporins had had Pasteurella (66.66%), Citrobacter, Enterobacter, Morganella (50%) and Proteus strains (40%).
