Summary
Staphylococcus pseudintermedius, a bacteria common in pets, is increasingly causing human infections. This case highlights a complicated urinary tract infection with persistent bacteremia in an elderly patient with ureteral stents.
Area of Science:
- Veterinary Medicine
- Human Infectious Diseases
- Microbiology
Background:
- Staphylococcus pseudintermedius is a significant pathogen in companion animals.
- Zoonotic transmission of S. pseudintermedius to humans is an emerging concern.
- Urinary tract infections (UTIs) can lead to severe complications, especially in vulnerable populations.
Observation:
- A case of complicated UTI caused by S. pseudintermedius in an elderly patient.
- The patient had undergone recent bilateral ureteral stent placement.
- Persistent high-grade bacteremia was noted during the infection.
Findings:
- S. pseudintermedius successfully treated in a human patient.
- Demonstrates the potential for S. pseudintermedius to cause severe invasive infections in humans.
- Highlights the importance of considering animal-to-human pathogen transmission.
Implications:
- Clinicians should be aware of S. pseudintermedius as a potential cause of human infections, particularly in patients with animal contact.
- Ureteral stent placement may represent a risk factor for complicated UTIs from unusual pathogens.
- Further research is needed to understand the epidemiology and clinical spectrum of S. pseudintermedius zoonoses.

275
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

111
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

122
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...

203
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...
