DENAMIEL, G et al. Prevalence and resistance profile to beta-lactam antibiotics in staphylococci from dogs and cats. InVet [online]. 2009, vol.11, n.2, pp.117-122. ISSN 1668-3498.

The purpose of this study was to characterize the prevalence and resistance profile to betalactam antibiotics of staphylococci isolated from canine and feline infections. Staphylococci were isolated from 207 dog samples. The species frequency for identified staphylococci were: S. intermedius 29.5%, S. aureus and S. simulans 20.8%, S. saprophyticus 12.6%, S. chromogenes 10.6%, S. haemolyticus 3.9% and S. epidermidis 1.9%. Sixty three staphylococci isolates were from cats: S. simulans 33.3%, S. intermedius and S. aureus 15.4%, S. saprophyticus 11.1%, S. haemolyticus 6.34%, S. chromogenes and S. epidermidis 3.5%. Resistance to penicillin in samples from dogs were: S. intermedius 47.5%, S. aureus 34.8% and S. saprophyticus 7.7%. Methicillin-resistance was evidenced in S. intermedius 9.8% and S. saprophyticus 3.8%. In samples from cats, penicillin-resistant staphylococci were: S. saprophyticus 42.8%, S. aureus and S. intermedius 15.4% and S. simulans 9.5%. Methicillinresistant staphylococci were not found among cat isolates.
