What is the treatment for Nasal Pluralibacter gergoviae infection?

Treatment of Nasal Pluralibacter gergoviae Infection

Amoxicillin-clavulanate is the recommended first-line treatment for nasal Pluralibacter gergoviae infection due to its broad spectrum of activity against respiratory pathogens including Enterobacteriaceae family members. 1

First-Line Treatment Options

• Amoxicillin-clavulanate at a dosage of 1.75-4 g/250 mg per day for adults is the preferred initial therapy 1
• Alternative options for patients with penicillin allergy include:
  • Second-generation cephalosporins: cefuroxime-axetil 2
  • Third-generation cephalosporins: cefpodoxime-proxetil, cefotiam-hexetil 2
  • Pristinamycin (particularly for beta-lactam allergic patients) 2

Duration of Treatment

• Standard duration is 7-10 days for most cases 2, 1
• Cefuroxime-axetil and cefpodoxime-proxetil have demonstrated efficacy with shorter 5-day regimens 2
• For more severe infections, longer courses may be necessary 1

Management of Treatment Failures or Resistant Strains

• If no clinical improvement after 72 hours of initial therapy, consider: 1
  • Switching to respiratory fluoroquinolones (levofloxacin, moxifloxacin) 2, 1
  • Increasing to high-dose amoxicillin-clavulanate (4 g/250 mg per day) 1
• For severe infections or confirmed resistant strains, consider parenteral therapy with ceftriaxone 1 g/day IM or IV 1

Adjunctive Therapies

• Intranasal saline irrigation to help alleviate symptoms and improve mucociliary clearance 1, 3
• Intranasal corticosteroids may provide symptomatic relief, especially if there is significant inflammation 1
• Short-term decongestants (no more than 3 days for topical formulations to avoid rebound congestion) 3

Special Considerations for Pluralibacter gergoviae

• P. gergoviae is an emerging multidrug-resistant species of the Enterobacteriaceae family that has been found to carry various resistance genes 4
• The species has been identified with genes encoding extended-spectrum β-lactamases, carbapenemases, and mobile colistin resistance 4
• Due to potential antimicrobial resistance, obtaining cultures before initiating therapy or if initial therapy fails is advisable 2

Monitoring and Follow-up

• Clinical improvement should be expected within 72 hours of appropriate antibiotic therapy 1
• If symptoms persist or worsen after 72 hours:
  • Consider changing antibiotic therapy based on likely resistance patterns 1
  • Obtain cultures if not previously done 2
  • Evaluate for complications or alternative diagnoses 1

Decolonization for Recurrent Infections

• For recurrent nasal infections, consider a decolonization regimen: 2
  • Nasal decolonization with mupirocin 2% ointment applied twice daily for 5-10 days 2, 5
  • Consider adding topical body decolonization with chlorhexidine for 5-14 days or dilute bleach baths 2

Prevention Strategies

• Maintain good personal hygiene with regular hand washing 2
• Avoid sharing personal items that contact the nose or face 2
• Environmental cleaning focused on high-touch surfaces 2

This treatment approach acknowledges the emerging resistance patterns in P. gergoviae while providing a structured management plan based on current guidelines for similar respiratory pathogens.
