The aim of this study was to evaluate antimicrobic resistance in canine staphylococci to the major classes of antimicrobials used in veterinary dermatology. The data was collected in 2002-2006 in the Dr L. Kriauceliunas small animal clinic of the Lithuanian Veterinary Academy. Clinical evaluation of 163 dogs was performed together with microscopical, mycological and bacteriological examinations. The clinical evaluation included the age of the dog, breed, sex, hair structure and season of the year. The authors found out that during the 5 year period males got the disease more often than females (52.98% versus 42.02%) and dogs at the ages of 1-5 years were the most common patients (43.9%). Bacterial skin diseases were more common in short-haired dogs (61.81%, p < 0.05). Long-haired dogs were more likely to be affected by bacterial skin diseases in the cold season (p < 0.05). Bacteriological examination revealed that the most common cause of bacterial skin infections was Staphylococcus intermedius (71.76%, p < 0.05) and Staphylococcus aureus (23.68%, p < 0.05). Mixed cultures (Staphylococcus spp., Streptococcus spp., Pseudomonas spp. and Escherichia coli) were found to be the cause of 4.56% (p < 0.05) of all bacterial skin diseases. S. intermedius and S. aureus strains exhibited the best sensitivity to ciprofloxacin, amikacin, methicillin (100%) and to cephadroxil (respectively 91.75% and 100%). S. intermedius strains were most resistant to sulphanilamides/trimethoprim (82.28%), S. aureus - to amoxicillin (86.0%).
