Abstract
To determine the antibiotypes and frequency of toxin genes in methicillin-resistant Staphylococcus pseudintermedius (MRSP), 281 nasal swab samples were collected from dogs and dog guardians in Abakaliki, Southeastern Nigeria. Antimicrobial susceptibility testing was determined by disc diffusion technique while detection of toxin genes was carried out by PCR. Exactly 41 (28.7 %) and 6 (4.3 %) MRSP were obtained from dogs and dog guardians respectively. Isolates exhibited resistance (100–16.7 %) to amoxicillin-clavulanic acid, cephalosporins, fluoroquinolones, and carbapenems. Seccanine, lukD, siet, and exi toxin genes were harboured by 42 (89.4 %), 47 (100 %), 37 (78.7 %), and 2 (4.3 %) MRSP isolates respectively. This study has shown that dogs and dog guardians in Abakaliki, Southeastern Nigeria are colonized by multiple drug-resistant MRSP which harbour toxin genes. This represents a significant public health problem in veterinary and human medicine.
