Abstract

Insights

Antimicrobial resistance is rising globally, leading to more severe intra-abdominal infections (IAIs). Judicious antibiotic use is crucial to preserve current treatments due to a lack of new drug development.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Surgical Infections

Background:

  • Worldwide increase in infections caused by multidrug-resistant microorganisms.
  • Rising prevalence of antibiotic-resistant pathogens in intra-abdominal infections (IAIs), including specific bacteria and fungi.
  • Observed increase in pathogens like carbapenem-resistant Pseudomonas aeruginosa, Acinetobacter baumannii, and ESBL-producing E. coli.

Purpose of the Study:

  • To highlight the growing challenge of antimicrobial resistance in IAIs.
  • To emphasize the clinical consequences of multidrug-resistant infections.
  • To underscore the need for understanding antimicrobial resistance epidemiology.

Main Methods:

  • Observational analysis of trends in antimicrobial resistance.
  • Review of pathogens commonly associated with IAIs.
  • Assessment of the impact of resistance on morbidity and mortality.

Main Results:

  • Increased prevalence of multi-drug resistant pathogens in IAIs.
  • Significant rise in morbidity and mortality rates linked to IAIs.
  • Specific resistant organisms identified as major contributors.

Conclusions:

  • Surgeons must understand the epidemiology and clinical impact of antimicrobial resistance in IAIs.
  • Limited new antimicrobial agents in development necessitate careful drug management.
  • Judicious antimicrobial stewardship is essential to maintain the efficacy of existing treatments.

Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within...

Development of Antibiotic Resistance01:30

Development of Antibiotic Resistance

Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...

Mechanism of Antibiotic Resistance in MRSA01:25

Mechanism of Antibiotic Resistance in MRSA

Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

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...

Urine Studies II: Urine Culture and Sensitivity Test

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...

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...
