Prevalence and antimicrobial resistance of species isolated from cats and dogs.

BACKGROUND

Methicillin-resistant staphylococci (MRS) are an emerging global problem with serious public health concern.

AIMS

This study investigated the prevalence and antimicrobial susceptibility of commensal species isolated from healthy and clinical cats and dogs.

METHODS

Nasal swab samples were collected from animals and processed using selective and semi-selective mediums. Presumptive isolates were subjected to biochemical testing and analyzed using the Phoenix automated identification and susceptibility testing system. PCRs protocols were used to screen for and pvl genes.

RESULTS

In total, 151 pets (103 cats and 48 dogs) were enrolled, of which 14 dogs (29%) and 24 cats (23%) were colonized with various Staphylococcus species mainly originated from healthy animals. A total of 38 staphylococci isolates were collected and distributed between 24 coagulase-negative and 14 coagulase-positive staphylococci. Only 13 staphylococci strains were identified as MRS, out of which only five isolates expressed that the gene exclusively originated from healthy pets.

CONCLUSION

This is the first study reporting the prevalence and colonization status of staphylococci species and MRS strains isolated from cats and dogs in Libya. The study reports important information of medical and clinical importance on antimicrobial and multidrug resistance of different staphylococci strains, particularly the coagulase negative species.
