Role Of Aim2 Inflammasome In Pulmonary Host Defense Against Staphylococcus Aureus-Induced Pneumonia, Bibek Dhakal

LSU Master's Theses

Bacterial pneumonia is the leading cause of death in children under the age of five, claiming the lives of two million children each year. Staphylococcus aureus is the extracellular Gram-positive bacteria that causes necrotizing pneumonia. Moreover, the spread of antibiotic-resistant and hypervirulent strains has made treatment more challenging. Absent in melanoma 2 (AIM2) is a dsDNA-sensing cytosolic innate immune receptor that activates inflammasomes and is crucial for host defense against intracellular bacteria and DNA viruses. However, its role in extracellular bacterial pathogen-induced pneumonia is unclear. Therefore, understanding how AIM2 initiates host responses during Staphylococcus aureus is crucial for the development …

Advancing Rna Virus Discovery And Biology With Whole Genome Sequencing, Mariah Katherine Taylor

Theses and Dissertations (ETD)

Two RNA virus families that pose a threat to human and animal health are Hantaviridae and Coronaviridae. These RNA viruses which originate in wildlife continue and will continue to cause disease, and hence, it is critical that scientific research define the mechanisms as to how these viruses spillover and adapt to new hosts to become endemic. One gap in our ability to define these mechanisms is the lack of whole genome sequences for many of these viruses. To address this specific gap, I developed a versatile amplicon-based whole-genome sequencing (WGS) approach to identify viral genomes of hantaviruses and severe acute …

Role Of Gut Microbiome In Covid-19: An Insight Into Pathogenesis And Therapeutic Potential, Ikram Hussain, Gabriel Liu Yuan Cher, Muhammad Abbas Abid, Muhammad Bilal Abid

Department of Pathology and Laboratory Medicine

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulted in an unprecedented global crisis. Although primarily a respiratory illness, dysregulated immune responses may lead to multi-organ dysfunction. Prior data showed that the resident microbial communities of gastrointestinal and respiratory tracts act as modulators of local and systemic inflammatory activity (the gut-lung axis). Evolving evidence now signals an alteration in the gut microbiome, brought upon either by cytokines from the infected respiratory tract or from direct infection of the gut, or both. Dysbiosis leads to a "leaky gut". The intestinal permeability then allows access to …

Mycobacterium Avium Pulmonary Infection Disguised As A Urinary Tract Infection, Megan Rolfzen, Allison Ashford

Graduate Medical Education Research Journal

In the United States, Mycobacterium avium complex (MAC) has been found to be the most common isolate in non-tuberculous disease, and pulmonary infection is the most frequent presentation. It is ubiquitous in the environment, particularly in soil and manufactured water supply sources. Worldwide, M. avium infections, both pulmonary and disseminated, are steadily increasing. Due to MAC’s ability to cause non-specific symptoms and its pervasiveness within the environment, it is paramount to incorporate this diagnosis in the differential, especially in those most susceptible. We report a case of a Mycobacterium avium complex pulmonary infection in 72-year-old Caucasian male with history of …

Assesment Of Antibiotic Resistant Gene Expression In Clinical Isolates Of Pseudomonas Aeruginosa, Dustin Esmond

Biology Theses

Increasing prevalence of nosocomial infections by antimicrobial resistant pathogens resulting in higher mortality rates and financial burden is of great concern. Pseudomonas aeruginosa represents one of six highly virulent “ESKAPE” pathogens that exhibit considerable intrinsic drug resistance as well as mechanisms for acquiring further resistance. As many of these mechanisms are regulated through gene expression, we sought to identify regulatory strategies and patterns at play in 23 clinical isolates collected from Baku, Azerbaijan and Tyler, Texas, USA. Real-time quantitative polymerase chain reaction was performed on six gene targets implicated in resistance and contrasted with antibiotic phenotypes. We found AmpC cephalosporinase …

Roux-en-y gastric bypass (RYGB) is one of the most common weight loss surgical procedures performed in the United States. Early post-operative small bowel obstruction is a rare but potentially morbid, complication of RYGB. We report two patients who underwent RYGB and required subsequent treatment for a post-operative small bowel obstruction. Their post-operative course was complicated by severe aspiration pneumonitis leading to hypoxemic respiratory failure requiring rescue with femoral veno-venous extracorporeal membrane oxygenation (V-V ECMO). Both patients were successfully extubated, weaned off V-V ECMO support, and discharged to home. These cases highlight the potential role of V-V ECMO for patients who …

Primary Ciliary Dyskinesia: Ancestral Haplotypes Analysis Of The Rsph4a Founder Mutation In Puerto Rico, Wilfredo De Jesús-Rojas, Dalilah Reyes De Jesús, Angélica M Nieves, Ricardo A Mosquera, Juan C Martinez-Cruzado

Faculty, Staff and Student Publications

Genetic mutations in >50 genes, including RSPH4A, can lead to primary ciliary dyskinesia (PCD). RSPH4A mutations affect radial spokes, which alter the configuration of the ciliary ultrastructure and lead to chronic oto-sinopulmonary disease. The RSPH4A [c.921+3_6delAAGT] founder mutation was described as one cause of PCD without laterality defects in Puerto Rico. The average Puerto Rican genetic composition includes 64% European, 21% African ancestral, and 15% Native-American or Taino, a native tribe in the Caribbean at the start of the European colonization, genes. Due to the relatively elevated Taino ancestry on the island, it might have contributed to the endemicity of …
