Salmonella enterica serovar Typhi is the causative agent of typhoid fever restricted to humans and does not replicate in commonly used inbred mice. Genetic variation in humans is far greater and more complex than that in a single inbred strain of mice. The Collaborative Cross (CC) is a large panel of recombinant inbred strains which has a wider range of genetic diversity than laboratory inbred mouse strains. We found that the CC003/Unc and CC053/Unc strains are permissive to intraperitoneal but not oral route of S. Typhi infection and show histopathological changes characteristic of human typhoid. These CC strains are immunocompetent, …

Streptococcus suis is a significant pathogen in pigs and a newly emerging zoonotic agent in humans. The presence of multiple serotypes and strains with diversified sequence types in pig herds highlights the need for the identification of broadly cross-reactive universal vaccine antigen targets, capable of providing cross-protection against S. suis infection. Subunit vaccines based on the conserved proteins shared between different S. suis serotypes are potential candidates for such a universally protective vaccine. In the present study, phosphate ABC transporter ATP-binding protein PstB (PstB), an immunogenic protein of the S. suis bacterium, was expressed and purified, and then subjected to …

Editorial: What Does Not Kill You Makes You Stronger: Interactions Between Environmental Stresses And Microbial Virulence, Liang Wang, Ling-Jun Zhan, Michael J. Wise

Research outputs 2022 to 2026

The intriguing sit-and-wait hypothesis predicts that “virulence should be positively correlated with durability in the external environment because high durability reduces the dependence of transmission on host mobility” (Walther and Ewald, 2004) (Figure 1). Since the hypothesis was first proposed in the late 20th century (Ewald, 1983), both theoretical and computational studies have been reporting the relationships between environmental durability and microbial virulence (Sundberg et al., 2014; Wang et al., 2017, 2018, 2019a,b, 2020; Rafaluk-Mohr, 2019; Li et al., 2021) [...].

Interdependent Progression Of Bidirectional Sister Replisomes In E Coli, Po Jui Chen, Anna B Mcmullin, Bryan J Visser, Qian Mei, Susan M Rosenberg, David Bates

Faculty, Staff and Students Publications

Bidirectional DNA replication complexes initiated from the same origin remain colocalized in a factory configuration for part or all their lifetimes. However, there is little evidence that sister replisomes are functionally interdependent, and the consequence of factory replication is unknown. Here, we investigated the functional relationship between sister replisomes in Escherichia coli, which naturally exhibits both factory and solitary configurations in the same replication cycle. Using an inducible transcription factor roadblocking system, we found that blocking one replisome caused a significant decrease in overall progression and velocity of the sister replisome. Remarkably, progression was impaired only if the block …

A 68-Year-Old Man With Multiple Comorbidities Presents With A Weeping Wound Of The Left Lower Extremity: A Case Report, Hameed Ali

Journal of Community Hospital Internal Medicine Perspectives

In cases of cellulitis, identification of a specific pathogen is often not possible on clinical grounds, and in our institution the recommended practice for empiric treatment of skin infections is to cover for the usual pathogens, such as Staphylococcus aureus and Streptococcus pyogenes. This article describes the management of a 68-year-old man in whom the choice of appropriate antibiotic treatment for suspected cellulitis was complicated by many factors, including several known risk factors for recurrent cellulitis, multiple comorbid conditions, and the patient’s wish to leave hospital as soon as possible. Given this patient’s clinical syndrome, coverage for methicillin-resistant S. aureus …

Clonorchis Sinensis, a common liver fluke, is known to cause biliary disease and can present with a wide array of symptoms. It’s mostly found in Asian countries due to consumption of undercooked or raw fish. Although Cholangiocarcinoma is a known serious complication of this disease, Pancreatic neoplasms are rare and have seldom been reported. Here, we report a case of an 80-year-old man who presents with pancreatic adenocarcinoma associated with Clonorchis Sinensis infection

Acute Diarrhea Isn’T Always Infectious: An Atypical Presentation Of Adrenal Insufficiency, Ariana Tagliaferri, Arielle Aiken, Madhav Patel, Monisha Singhal

Journal of Community Hospital Internal Medicine Perspectives

Adrenal insufficiency can be a primary or secondary disorder occurring from a hormone deficiency or suppression of the hypothalamic-pituitary axis from various etiologies. The diagnosis can be challenging given the lack of specificity and indolence of symptoms. Diarrhea is not a typical presenting symptom of adrenal insufficiency and can be overlooked as an infectious disease during an adrenal crisis. Herein we present a patient with an undiagnosed adrenal insufficiency who presented with subacute diarrhea during an adrenal crisis after a dental procedure and esophagogastroduodenoscopy.

Applying Game Theory Models To Inpatient Medicine: Opportunities To Improve Care, Ho-Man Yeung, Shreya Makkapati

Journal of Community Hospital Internal Medicine Perspectives

Inpatient hospital costs have been increasing exponentially in the United States. Part of this increase is attributed to over and undertreatment, leading to higher costs and potential patient harm. Research improving clinician-patient interactions can help minimize and optimize the costs. Game theory has the ability improve clinician- patient interaction by modeling outcomes. Using variations of game theory, the bad doctor bad patient stigma can reframed to incentives. We believe the use of different models (prisoner dilemma, centipede game, assurance game, and chicken game) can outline the challenges faced during common inpatient scenarios, including end of life conversations and aggressive procedures. …

Discovery And Characterization Of A New Class Of O-Linking Oligosaccharyltransferases From The Moraxellaceae Family, Cory J Knoot, Paeton L Wantuch, Lloyd S Robinson, David A Rosen, Nichollas E Scott, Christian M Harding

2020-Current year OA Pubs

Bacterial protein glycosylation is commonly mediated by oligosaccharyltransferases (OTases) that transfer oligosaccharides en bloc from preassembled lipid-linked precursors to acceptor proteins. Natively, O-linking OTases usually transfer a single repeat unit of the O-antigen or capsular polysaccharide to the side chains of serine or threonine on acceptor proteins. Three major families of bacterial O-linking OTases have been described: PglL, PglS, and TfpO. TfpO is limited to transferring short oligosaccharides both in its native context and when heterologously expressed in glycoengineered Escherichia coli. On the other hand, PglL and PglS can transfer long-chain polysaccharides when expressed in glycoengineered E. coli. Herein, we …

Echinococcus Multilocularis Calreticulin Interferes With C1q-Mediated Complement Activation, Siqi Xian, Lujuan Chen, Yan Yan, Jianfang Chen, Guixia Yu, Yuxiao Shao, Bin Zhan, Yanhai Wang, Limei Zhao

Faculty, Staff and Students Publications

As a zoonotic disease caused by Echinococcus multilocularis larvae, alveolar echinococcosis (AE) is one of the most severe forms of parasitic infection. Over a long evolutional process E. multilocularis has developed complex strategies to escape host immune attack and survive within a host. However, the mechanisms underlying immune evasion remain unclear. Here we investigated the binding activity of E. multilocularis calreticulin (EmCRT), a highly conserved Ca2+-binding protein, to human complement C1q and its ability to inhibit classical complement activation. ELISA, Far Western blotting and immunoprecipitation results demonstrated that both recombinant and natural EmCRTs bound to human C1q, …

The Relationship Between Endotracheal Tube Different Cuff Pressure Measurements And The Incidence Of Ventilator-Associated Pneumonia, Menattallah Mohamed

Nursing

Endotracheal tube cuff pressure measurement is an essential practice for management of mechanically ventilated patients. Based on guidelines, it’s recommended to maintain the endotracheal tube cuff pressure within a range between 20-30cm H2O. When the endotracheal tube cuff pressure is lower than the normal range, it increases the risk of micro-aspirations and the passage of contaminated secretions of the oral cavity into the trachea; this potentially causing aspiration pneumonitis and ends with ventilator associated pneumonia. This study aimed to assess the relationship between endotracheal tube different cuff pressure measurements and the incidence of ventilator associated pneumonia. A non-randomized descriptive correlational …

Engineering At-Home Dilution And Filtration Methods To Enable Paper-Based Colorimetric Biosensing In Human Blood With Cell-Free Protein Synthesis, Tyler J. Free, Ryan W. Tucker, Katelyn M. Simonson, Sydney A. Smith, Caleb M. Lindgren, William G. Pitt, Bradley C. Bundy

Faculty Publications

Diagnostic blood tests can guide the administration of healthcare to save and improve lives. Most clinical biosensing blood tests require a trained technician and specialized equipment to process samples and interpret results, which greatly limits test accessibility. Colorimetric paper-based diagnostics have an equipment-free readout, but raw blood obscures a colorimetric response which has motivated diverse efforts to develop blood sample processing techniques. This work uses inexpensive readily-available materials to engineer user-friendly dilution and filtration methods for blood sample collection and processing to enable a proof-of-concept colorimetric biosensor that is responsive to glutamine in 50 µL blood drop samples in less …
