Streptococcus Canis Native Aortic Valve Endocarditis Linked To Cat Exposure: A Case Report And Review, Michael S. Wang, Maria Huaringa, Lauren Feld, Ken Ochiai, Tiffany Whelan, Nicholas M. Frazier

Journal of Community Hospital Internal Medicine Perspectives

Streptococcus canis is an uncommon human pathogen, but documented infections have been mostly associated with exposure to dogs. There are only five documented cases of endocarditis secondary to streptococcus canis, with all cases except one documenting exposure to a canine. We present a 74-year-old male with a history of Type 2 diabetes mellitus, CKD 3, moderate aortic stenosis and remote exposure to agent orange, who was found to have Streptococcus canis native valve endocarditis without exposure to a dog. To the best of our knowledge this case is the first case of endocarditis linked to feline exposure.

Convolutional Neural Network Based Analysis - An Aid To Diagnose Bacterial And Fungal Osteomyelitis, Saiprasad Alva, Dominic Augustine, Sowmya Sv, Mukul Saini, Sanjana Shetty

Annual Research Symposium

Osteomyelitis may be classified as Bacterial (Actinomycotic), Fungal (Mucormycotic), or combined based on the etiological agent. During histopathological examination, there is a high chance that bacterial colonies or fungal hyphae may be missed by the human eye, especially when there is a paucity of organisms. This may lead to a faulty diagnosis of the type of osteomyelitis which along with an improper treatment plan would cause further progression of the disease and various other complications. Therefore, the diagnosis of the exact etiological variant of osteomyelitis is of prime importance to design an appropriate treatment plan. In the present study, bone …

The Transmission Of Oropharyngeal Squamous Cell Carcinoma, Kunjal Patel, Aleesha Thomas

Mako: NSU Undergraduate Student Journal

The existence of Oropharyngeal Squamous Cell Carcinoma (OPSCC) has recently been found to have correlations with the Human Papillomavirus. HPV-associated OPSCC exhibits a unique method of infection and transmission and has made this branch an emerging disease in the recent decade. This systematic review of the literature was conducted to further explore research into Oropharyngeal Squamous Cell Cancer (OPSCC). Commonly referred to as “throat cancer”, this growth originates in the oropharynx. Symptoms of this condition include sore throat, lumps in the neck, and difficulty with swallowing. OPSCC has many variants but has shown a strong association with Human Papillomavirus (HPV), …

Impaired Neutrophil Extracellular Trap-Forming Capacity Contributes To Susceptibility To Chronic Vaginitis In A Mouse Model Of Vulvovaginal Candidiasis, Junko Yano, Paul L. Fidel

School of Dentistry Faculty Publications

Vulvovaginal candidiasis (VVC), caused by is characterized by aberrant inflammation by polymorphonuclear neutrophils (PMNs) in the vaginal lumen. Data from the established murine model shows that despite potent antifungal properties, PMNs fail to clear due to local heparan sulfate that inhibits the interaction between PMNs and , resulting in chronic vaginal immunopathology. To understand the role of neutrophil extracellular traps (NETs) in defense against at the vaginal mucosa, we investigated the NET-forming capacity of PMNs in chronic VVC-susceptible (CVVC-S/C3H) and -resistant (CVVC-R/CD-1) mouse strains. Immunofluorescence revealed the formation of NETs (release of DNA with PMN-derived antimicrobial proteins) in PMN cocultures …

School of Medicine Faculty Publications

Introduction The burden of multiple drug resistance in human pathogens has necessitated the search for and development of antimicrobial agents with a wide range of structural classes and potentials to selectively act on the several mechanisms of actions exhibited by the pathogens. However, most synthetic antimicrobial agents have been linked with adverse side effects and high costs, furthering the need to explore more options. Syzygium cumini, Moringa oleifera, and Tinospora cordifolia are three medicinal plants used in traditional medicine systems for various infectious diseases. They contain various phytochemicals that exhibit antimicrobial activities against various bacteria, fungi, and parasites. The mechanisms …

The Development Of A Rabies Virus-Vectored Vaccine Against Borrelia Burgdorferi, Targeting Bbi39, Shantel Rios, Bibek Bhattachan, Kruthi Vavilikolanu, Chrysoula Kitsou, Utpal Pal, Matthias J. Schnell

Department of Microbiology and Immunology Faculty Papers

Lyme disease (LD) is the most common tick-borne illness in the United States (U.S.), Europe, and Asia. Borrelia burgdorferi, a spirochete bacterium transmitted by the tick vector Ixodes scapularis, causes LD in the U.S. If untreated, Lyme arthritis, heart block, and meningitis can occur. Given the absence of a human Lyme disease vaccine, we developed a vaccine using the rabies virus (RABV) vaccine vector BNSP333 and an outer surface borrelial protein, BBI39. BBI39 was previously utilized as a recombinant protein vaccine and was protective in challenge experiments; therefore, we decided to utilize this protective antigen in a rabies virus-vectored vaccine …

A Rare Case Of Iga Vasculitis In An Adult Patient With Mssa Bacteremia And Prostate Abscess, Maria E Mesalles, Erinolaoluwa F Araoye, Anees Siddiqi, Adrien Janvier

Journal of Community Hospital Internal Medicine Perspectives

IgA vasculitis, previously known as Henoch Schönlein Purpura (HSP), is a disease more common in children and occurs when IgA1 immune complexes attach to the walls of small blood vessels causing inflammation. This case report is of an adult male who presented with a purpuric rash affecting both legs, microhematuria, and knee pain. Blood cultures were positive for Methicillin-sensitive Staphylococcus aureus (MSSA). Computed tomography of the pelvis revealed a prostate abscess. Skin biopsy demonstrated IgA and C3 in the dermal vessels. To our knowledge, this is the first report of IgA vasculitis associated with MSSA bacteremia due to a prostate …

Rare Case Of Mycobacterium Avium Complex Peritonitis In A Patient With Multiple Myeloma Undergoing Peritoneal Dialysis, Sacide S. Ozgur, Nida Ansari, Dhruv Patel, Ryan Rahman, Raymond Shih

Journal of Community Hospital Internal Medicine Perspectives

Mycobacterium avium complex (MAC) infections can present as a variety of severe diseases. While it has a predilection for immunocompromised patients such as those with Human immunodeficiency virus (HIV), it can also affect immunocompetent patients as well. One of the rare yet severe diseases that MAC infections can present is MAC peritonitis. Often hard to distinguish from other causes of peritonitis, high clinical suspicion should be maintained for those who are susceptible. Here we present an 85-year-old female with a past medical history of end-stage renal disease on peritoneal dialysis who presented with nausea and vomiting. She was found to …

Catheter-associated urinary tract infections (CAUTIs), a common cause of healthcare-associated infections, are caused by a diverse array of pathogens that are increasingly becoming antibiotic resistant. We analyze the microbial occurrences in catheter and urine samples from 55 human long-term catheterized patients collected over one year. Although most of these patients were prescribed antibiotics over several collection periods, their catheter samples remain colonized by one or more bacterial species. Examination of a total of 366 catheter and urine samples identify 13 positive and 13 negative genus co-occurrences over 12 collection periods, representing associations that occur more or less frequently than expected …

A Unique Case Of Spontaneous Pectoral Abscess, Martin Sentmanat, Zachary Shields, David Ross

North Texas GME Research Forum 2024

Pyomyositis is a rare disease that is often misdiagnosed. Formerly more common in tropic areas, it has been more prevalent in temperate climates in the past couple of decades. Most cases of pyomyositis have a known cause or the patient is immunocompromised, but there are a few documented cases of spontaneous pyomyositis in an otherwise healthy patient. Our case describes a 35-year-old male with no past medical history or history of IV drug use who presented to the emergency department with right sided chest pain. The patient was initially seen and diagnosed with a pectoral muscle strain and fever. He …

A Common Complaint With An Unexpected Diagnosis: A Case Of Mycobacterium Avium Complex Pulmonary Abscesses, Maryam Fallahi, Mark Cheneler, Qazi Haider, Madhukanth Reddy

North Texas GME Research Forum 2024

Introduction: Mycobacterial infections are an atypical organism for pulmonary infections. These infections are classically separated in tuberculous (MTB) and nontuberculous (NTM) groups due to their differing pathogenicity and microbiologic therapy regimens. MTB is typically treated with a 4-drug therapy known as RIPE (rifampin, isoniazid, pyrazinamide, and ethambutol) however NTM is typically treated with 3- or 4-drug therapy with a backbone of rifampin, macrolide, and ethambutol. Due to the long courses of therapy required for NTM, stringent diagnostic criteria of clinical, radiologic, and microbiologic findings are required. Despite meeting all 3 criteria for diagnosis, not every patient is a candidate for …

Case Report: Streptococcus Gallolyticus Prosthetic Joint Infection, Jeffrey Dickerson, Liza Salloum, Amaan Sheikh, Madhukanth Reddy, Bryan Youree

North Texas GME Research Forum 2024

Streptococcus gallolyticus, part of the Streptococcus bovis/Streptococcus equinus complex (SBSEC) formerly known as Group D streptococi, is strongly associated with colorectal cancer and infective endocarditis. Its appearance in septic arthritis is rare, and its role in septic arthritis has not been as thoroughly investigated. We present the case of a 69 year old male with a history of atrial fibrillation and hypertension who was admitted to our hospital after undergoing a right knee replacement in 2023 with a chief complaint of right knee pain, fever, and chills. Arthrocentesis and blood cultures were performed, and the patient was started on …

The Impact Of Tamsulosin And Duration In Catheter-Associated Uti (Cauti) At Weatherford, Feeza Hasan, Diana Steedley, Maria Guerrero, Muhammad Siddique

North Texas GME Research Forum 2024

Among Catheter-Associated Urinary Tract Infections (CAUTI) acquired in the hospital, approximately 75% are associated with a urinary catheter, which is a tube inserted into the bladder through the urethra to drain urine. Between 15-25% of hospitalized patients receive urinary catheters during their hospital stay. A urinary tract infection (UTI) is an infection involving any part of the urinary system, including urethra, bladder, ureters, and kidney. UTIs are the most common type of healthcare-associated infection reported to the National Healthcare Safety Network (NHSN). The most important risk factor for developing a CAUTI is prolonged use of the urinary catheter. Therefore, catheters …
