Summary
This study reports the first case of recurrent bacteremia caused by Achromobacter piechaudii in an immunocompromised patient with an intravenous catheter. This finding highlights a rare bacterial infection associated with medical devices.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Clinical Case Reports
Background:
- Recurrent bloodstream infections (bacteremia) pose significant clinical challenges, particularly in immunocompromised individuals.
- Intravenous catheters are common sources of healthcare-associated infections, often linked to bacterial colonization and subsequent bacteremia.
- Achromobacter species, previously classified under Alcaligenes, are increasingly recognized as opportunistic pathogens.
Observation:
- A 73-year-old immunocompromised man presented with recurrent bacteremia.
- The bacteremia was associated with an intravenous catheter.
Findings:
- The causative agent was identified as Achromobacter piechaudii (formerly Alcaligenes).
- This represents the first documented case of bacteremia due to A. piechaudii.
Implications:
- Highlights A. piechaudii as a potential pathogen in catheter-associated infections.
- Emphasizes the importance of vigilant monitoring for unusual pathogens in immunocompromised patients.

Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
