Identificación y resistencia antimicrobiana de Staphylococcus aureus provenientes de lesiones piodérmicas de perros (Canis lupus familiaris)

Abstract

The objective of the present investigation was to identify the presence of Staphylococcus aureus bacteria in 153 dogs without distinction of sex, age and breed, which had pyodermic lesions as the main inclusion criteria. These patients underwent a dermatological examination, cytology, culture, bacterial identification and the positive ones of S. aureus underwent an antibiogram with the main antibiotics currently used (amoxicillin plus clavulanic acid, cephalexin, ampicillin, ceftriaxone, ciprofloxacin, neomycin, gentamicin, azithromycin, tetracycline, doxycycline, chloramphenicol, and rifampin). In the present investigation, a frequency table was performed with a 95% confidence interval, a logistic regression, Odds Ratio and a Chi Square test, of the 153 samples obtained, 17 were positive for S. aureus, representing 11.11% of the population, these samples were processed for antibiogram, greater resistance to ampicillin and tetracycline was obtained, in the same way multiresistance according to the odds ratio is more present in geriatric patients, males with recurrent deep pyodermas, external deworming of less than 1 year and with onset of signs of less than 12 months of evolution. It is concluded in this way that there is presence of this pathogen and its multi-resistance, this type of patients should be considered and if they already have recurrent pyoderma problems, always carry out a culture and antibiogram to determine the specific treatment for each patient and avoid more antibacterial resistance and its zoonotic risk.
