Expert Review of Anti-Infective Therapy
|August 28, 2013
Summary
Plague, caused by Yersinia pestis, remains a threat with emerging antibiotic resistance. Research reviews current and novel treatments and discusses the development of next-generation plague vaccines.
Area of Science:
- Microbiology and Immunology
- Infectious Diseases
- Bacteriology
Background:
- Plague, a historical scourge caused by Yersinia pestis, continues to cause outbreaks globally.
- Current prophylactic and therapeutic strategies face challenges, including emerging antibiotic resistance in Yersinia pestis.
- Existing plague vaccines have limitations in safety and efficacy, with none currently licensed in the USA or Western Europe.
Purpose of the Study:
- To review the virulence mechanisms of Yersinia pestis.
- To examine available and developing prophylactic and therapeutic strategies for plague.
- To discuss the development of safe and effective next-generation plague vaccines.
Main Methods:
- Literature review of Yersinia pestis virulence factors.
- Analysis of current antibiotic treatments and emerging resistance patterns.
- Evaluation of historical, current, and novel vaccine development approaches for plague.
Main Results:
- Yersinia pestis employs complex virulence mechanisms that necessitate robust control strategies.
- Antibiotic resistance in Yersinia pestis is a growing concern, limiting therapeutic options.
- Development of next-generation vaccines, such as recombinant subunit vaccines, shows promise for safe and effective plague prevention.
Conclusions:
- Effective plague control requires understanding Yersinia pestis virulence and addressing therapeutic challenges.
- Innovative approaches are crucial for developing new anti-plague therapeutics and vaccines.
- Next-generation vaccines are essential for future plague prevention, particularly given the limitations of current options.

01:28Pulmonary Tuberculosis V
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

01:28Acute 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...
01:28Pneumonia IV: Management
The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

01:30Lytic Cycle of Bacteriophages
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the lytic replication...
01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
