Patients were randomly divided into three groups (n=10) according to the irrigation modality to be used; group I: syringe irrigation (NaOCl 2.625%), group II: NaOCl 2.625%+EndoActivator and group III: NaOCl 2.625%+diode laser. Before obturation, samples S2 were collected and PCR analysis was performed to identify …

Ecthyma Gangrenosum And Panniculitis Secondary To Acute Pseudomonas Myositis Without Bacteremia, Heather Gosnell, Matthew Burke, Joseph Shnouda

HCA Healthcare Journal of Medicine

Introduction

Ecthyma gangrenosum (EG) is a relatively uncommon cutaneous manifestation of an underlying Pseudomonas aeruginosa infection and is clinically described as necrotic with gangrenous ulcers surrounded by erythematous halos. Cases of EG may occur in the absence of bacteremia and have been increasingly reported in literature. Here we present a patient with features of both EG and panniculitis, despite the lack of underlying bacteremia.

Clinical Findings

A 57-year-old male presented to the emergency department with unrelenting right-sided lower back pain and an “itchy and painful” rash of four to five day duration. The patient had an extensive history of intravenous …

Microbiological Study In A Gneissic Cave From Sri Lanka, With Special Focus On Potential Antimicrobial Activities, Ethige Isuru P. Silva, Pathmakumara Jayasingha, Saman Senanayake, Anura Dandeniya, Dona Helani Munasinghe

International Journal of Speleology

The emergence of antibiotic resistance is a global health crisis, thus the search for novel antimicrobial compounds has become a continuous necessity. Underexplored and extreme environments, such as cave ecosystems, have been identified as a promising potential source for the discovery of novel microorganisms with novel antimicrobial compounds (AMC). This study presents the first cave microbiological investigation in Sri Lanka, with a special preference for bioprospecting of novel AMC. The cave sediment characterization demonstrated the presence of close to strong acidic conditions (pH 3.1 – 3.3) and thus indicates the possibility of isolating acidophilic microorganisms. Eight cave wall/ceiling fungal strains …

Increasing Antibiotic Resistance In Shigella Bacteria In The United States, William J. Pharr

The Corinthian

Shigella bacteria cause half a million infections, 6,000 hospitalizations, and 70 deaths annually in the United States. These bacteria are of particular concern due to their high survivability, low infectious dose, and high adaptability. Cases of shigellosis from Shigella sonnei are becoming a more prevalent issue in the U.S. as the bacteria continues to develop higher resistance to today’s strongest antibiotics. Much of this resistance is connected to the exchange of genes between strains of Shigella due to insertion sequences (IS), intercontinental travel, and men who have sex with men (MSM). As a result of increased resistance, the use of …

Purpose: Legionella pneumophila pneumonia is a life-threatening, environmentally acquired infection identifiable via Legionella urine antigen tests (LUAT). We aimed to identify cumulative incidence, demographic distribution, and undetected disease outbreaks of Legionella pneumonia via positive LUAT in a single eastern Wisconsin health system, with a focus on urban Milwaukee County.

Methods: A multilevel descriptive ecologic study was conducted utilizing electronic medical record data from a large integrated health care system of patients who underwent LUAT from 2013 to 2017. A random sample inclusive of all positive tests was reviewed to investigate geodemographic differences among patients testing positive versus negative. Statistical comparisons …

Severity Of Disease And Mortality For Hospitalized Patients With Community-Acquired Viral Pneumonia Compared To Patients With Community-Acquired Bacterial Pneumonia, Richard Y. Kim, Thomas Chandler, Stephen P. Furmanek, Timothy Lee Wiemken, Rodrigo Cavallazzi

The University of Louisville Journal of Respiratory Infections

Background: There exists a large body of literature to help identify, diagnose, treat, and manage community-acquired pneumonia (CAP). Despite this, there is little data that directly compares the clinical syndromes and complications of pure bacterial pneumonia to pure viral pneumonia. Our study compares the clinical presentation, morbidity and mortality of viral vs. bacterial etiologies of CAP.

Methods: This was a secondary data analysis of the Community-Acquired Pneumonia Organization (CAPO) international study database. Data was collected concerning patient demographics, physical examination findings, laboratory findings, radiological findings, severity of illness, and clinical outcomes and stratified according to the two study groups, CAVP …

Use Of Urine Antigen Testing For Blastomyces In An Integrated Health System, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

Purpose: Blastomycosis, an endemic fungal infection, mimics many other diseases. We explored the use of Blastomyces urine antigen (BuAg), reportedly the most sensitive noninvasive test, in clinical practice and compared it to other noninvasive tests.

Methods: A total of 836 BuAg tests performed on unique patients (first test only) at one large integrated health system from June 2013 to May 2016 were retrospectively reviewed to examine test characteristics and demographic features. Of these, 100 cases from 2015, a year containing a large local blastomycosis outbreak, were randomly selected for detailed analysis.

Results: Demographics for the BuAg-tested population: mean age 54.9 …

Bacteriophages: The Answer To Antibiotic Resistance?, Allie Casto, Adam Hurwitz, Kunny Kou, Gregory Mansour, Allison Mayzel, Rachel Policke, Alexander Schmidt, Rowan Shartel, Olivia Smith, Augustus Snyder, Allison Woolf

James Madison Undergraduate Research Journal (JMURJ)

Bacteriophages, viruses that infect bacteria, have numerous applications in the medical, agricultural, and research fields, especially as an alternative to antibiotics in the age of antibiotic resistance. Phages are able to lyse, or break apart, bacterial cells with fewer side effects, more specificity, and less likelihood of resistance than antibiotics. The acceptance of phages in medicine and agriculture around the world today is not universal, and the United States Food and Drug Administration (FDA) has been slow to recognize phage therapy as a legitimate treatment. However, the successful use of phages in the past, as well as promising trial results …

Characterizing The Response Of Multidrug-Resistant Klebsiella Pneumoniae Species To The Application Of A Phage Cocktail, Steven Liu

Symposium

Project Summary: The application of bacteriophages to treat bacterial infections is known as phage therapy, which takes advantage of bacteriophage’s natural ability to infect and lyse bacterial hosts. Phages have been shaped by billions of years of evolution to be highly specialized deliverers of bactericidal agents to the cytoplasm of their target bacteria. Ever since discovery of bacteriophages in 1915, phage therapy was recognized as a potentially powerful tool for eliminating bacterial infections. The effectiveness of phage therapy can be increased by creating a mixture of multiple phages to target a wider variety of bacterial strains. Furthermore, phage therapy has …

The Bacteriology Of The Biliary Tract: A Preliminary Report., J. A. Sapala, J. L. Ponka, T. R. Neblett

Henry Ford Hospital Medical Journal

The bacterial flora of acute biliary tract disease has not been completely elucidated. The organisms identified most often were coliforms. Anaerobic culture technics were not precise enough to provide proper identification. In a 12-month study of 250 patients operated upon for inflammatory gallbladder disease, culture specimens were collected in a most strict and rigorous fashion. It was hoped that a more exact understanding of the relationship between bacteria and inflammatory biliary tract disease might be appreciated. Important technics were developed for gathering specimens, delivery to the laboratory and culturing. More meaningful results are to be expected In the future.
