Infección Cutánea Por Staphylococcus Spp Resistente A Antibióticos En Serpiente Cascabel (Crotalus Durissus).

Abstract

Antibiotic resistance represents a critical challenge in veterinary medicine, which is why the selection of an antimicrobial treatment must be based on appropriate diagnostic tools to avoid the indiscriminate use of these drugs. In this context, is reported the case of a wild specimen of Crotalus durissus that presented a skin lesion in the first third of the body, accompanied by evident infection, reduced mobility in the affected area and a deteriorated body condition. To establish an accurate diagnosis, additional tests will be carried out, including blood count, x-ray, coprology and antibiogram culture. The results revealed rib fracture, parasitism by Ophidascaris spp. and coccidia, as well as a skin infection caused by Staphylococcus spp. multi-resistant to third generation cephalosporins, tetracyclines, β-lactams, fluoroquinolones and sulfonamides. However, sensitivity to β-lactamase inhibitors (amoxicillin + clavulanic acid) and aminoglycosides (gentamicin) was identified. Faced with these challenges, treatment with gentamicin at a dose of 2.5 mg/kg intramuscularly was instituted, as the first-choice antibiotic (enrofloxacin) demonstrated resistance, this change in therapy demonstrated antibacterial effectiveness, promoting the patient's satisfactory recovery. This case highlights the importance of microbiological diagnosis in reptiles and the consequences of antimicrobial resistance on wildlife health, reinforcing the need to carry out additional studies on the impact on public health and on the conservation of this species.
