Multiscale Model Of Regional Population Decline In Little Brown Bats Due To White-Nose Syndrome, Andrew M. Kramer, Claire S. Teitelbaum, Ashton Griffin, John M. Drake
Multiscale Model Of Regional Population Decline In Little Brown Bats Due To White-Nose Syndrome, Andrew M. Kramer, Claire S. Teitelbaum, Ashton Griffin, John M. Drake
Integrative Biology Faculty and Staff Publications
- The introduced fungal pathogen Pseudogymnoascus destructans is causing decline of several species of bats in North America, with some even at risk of extinction or extirpation. The severity of the epidemic of white-nose syndrome caused by P. destructans has prompted investigation of the transmission and virulence of infection at multiple scales, but linking these scales is necessary to quantify the mechanisms of transmission and assess population-scale declines.
- We built a model connecting within-hibernaculum disease dynamics of little brown bats to regional-scale dispersal, reproduction, and disease spread, including multiple plausible mechanisms of transmission.
- We parameterized the model using the approach of …

Minimum Information About An Uncultivated Virus Genome (Miuvig), Simon Roux, Evelien Adriaenssens, Bas Dutilh, Eugene Koonin, Andrew Kropinski, Mart Krupovic, Mya Breitbart, Karyna Rosario
Marine Science Faculty Publications
We present an extension of the Minimum Information about any (x) Sequence (MIxS) standard for reporting sequences of uncultivated virus genomes. Minimum Information about an Uncultivated Virus Genome (MIUViG) standards were developed within the Genomic Standards Consortium framework and include virus origin, genome quality, genome annotation, taxonomic classification, biogeographic distribution and in silico host prediction. Community-wide adoption of MIUViG standards, which complement the Minimum Information about a Single Amplified Genome (MISAG) and Metagenome-Assembled Genome (MIMAG) standards for uncultivated bacteria and archaea, will improve the reporting of uncultivated virus genomes in public databases. In turn, this should enable more robust comparative …

Winter Habitats Of Bats In Texas, Melissa B. Meierhofer, Joseph S. Johnson, Samantha J. Leivers
KIP Articles
Few studies have described winter microclimate selection by bats in the southern United States. This is of particular importance as the cold-adapted fungus, Pseudogymnoascus destructans, which causes the fatal bat disease white-nose syndrome (WNS), continues to spread into southern United States. To better understand the suitability of winter bat habitats for the growth of P. destructans in this region, we collected roost temperature and vapor pressure deficit from 97 hibernacula in six ecoregions in Texas during winter 2016–17 and 2017–18. We also measured skin temperature of Rafinesque’s big-eared bats (Corynorhinus townsendii), Townsend’s big-eared bats (C. townsendii), big-brown bats (Eptesicus fuscus), …

Gram-Negative Rod Skin And Soft-Tissue Infections Following Breast Tissue Expander Surgery In Breast Cancer Patients, Ju Hee Katzman, Sadaf Aslam, Donna Mae M Pate, Nicole Guidish, Shelby Power, Clarissa Maravilla, Janelle Perkins, John Greene
Internal Medicine Faculty Publications
Background: Breast cancer patients who undergo tissue expander surgery (TES) are at an increased risk of developing gram-negative rod (GNR) skin and soft-tissue infection (SSIs) and its complications including prolonged antibiotic therapy, antibiotics side effects, and implant removal. Current perioperative antimicrobials focus mostly on gram-positive organisms, but the presence of a foreign body increases the risk of GNR SSI. We describe here the most common GNR bacteria and their susceptibility patterns that cause SSI after TES among breast cancer patients. Methods: We conducted a retrospective cohort study at Moffitt Cancer Center, Tampa, FL from January 2016, to January 2018, on …

Internal Medicine Faculty Publications
Background: Strongyloides stercoralis is a nematode endemic to the tropical and subtropical regions. In the United States, it is mostly found at southeastern states. Most infections are asymptomatic but disseminated and fatal infections have been reported in immunocompromised patients. At our institution, universal screening through Strongyloides antibody detection in serum among solid-organ transplant candidates began since 2010 and all seropositive candidates are treated before transplantation. We previously determined our incidence to be about 5%. The aim of this study was to determine demographic characteristics and risk factors that can be used for more cost-effective targeted screening.
Methods: We performed a …

A Case Series Of Staphylococcus Lugdunensis Infection In Cancer Patients At An Academic Cancer Institute In The United States, Dae Hyun Lee, Olga Klinkova, Jong-Wook Kim, Sowmya Nanjappa, John N. Greene
Internal Medicine Faculty Publications
Background: Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CoNS) that is a part of the normal human skin flora. Even though it belongs to CoNS family, it can cause severe and destructive infections in a similar fashion to Staphylococcus aureus. Skin and soft tissue infections (SSTI), bacteremia and endocarditis are amongst the most common clinical presentations. Diagnosis and clinical presentation of infections caused by S. lugdunensis in cancer patients is limited. Materials and Methods: We performed a retrospective chart review of 24 patients who had cultures positive for S. lugdunensis. Out of 24 patients, 14 patients were diagnosed with …

Nocardia Bejingensis: A Novel Isolate Affecting Immunocompromised Patients In The United States, Shylah M. Moore-Pardo, Johonna Asquith, Sadaf Aslam, Cynthia Mayer, John Greene, Sally Alrabaa
Internal Medicine Faculty Publications
Background: Nocardia species can cause localized or disseminated disease in humans. Infection results from direct inoculation or inhalation. In recent years, several new species have been identified via molecular methods. Further speciation is crucial as each organism has its own spectrum of disease and unique antibiotic susceptibility patterns. Immunosuppression, alcoholism, and certain lung diseases are well-established risk factors for nocardiosis. In fact, cases have incremented in association with increasing population of immunocompromised hosts as well as improved methods for detection and identification. Thus, Nocardia species may be considered opportunistic pathogens.
Nocardia bejingensis was first isolated in 2001 by Wang et …

Internal Medicine Faculty Publications
Aspergillosis refers to a spectrum of disorders that can occur due to colonization with the Aspergillus fungus. Allergic bronchopulmonary aspergillosis (ABPA) is an airway hypersensitivity reaction to the fungus that is almost exclusively seen in patients with cystic fibrosis or asthma. Here, we present a case of ABPA in a patient with a history of chronic cocaine use and tuberculosis and no history of asthma or cystic fibrosis. The patient had presented with progressively worsening dyspnea for three months as well as a 20-pound weight loss. Diagnosis was made with an elevated IgE against Aspergillus and chest CT findings, which …
The Utility Of Double Balloon Urinary Catheter In Reducing Rates Of Catheter-Associated Urinary Tract Infections In A Tertiary Care Teaching Hospital, Ju Hee Katzman, Cristina Vanessa Garcia, Seetha Lakshmi, Peggy Thompson, Lennox Archibald
The Utility Of Double Balloon Urinary Catheter In Reducing Rates Of Catheter-Associated Urinary Tract Infections In A Tertiary Care Teaching Hospital, Ju Hee Katzman, Cristina Vanessa Garcia, Seetha Lakshmi, Peggy Thompson, Lennox Archibald
Internal Medicine Faculty Publications
Background: Catheter-associated urinary tract infections (CAUTI) have been shown to increase hospital length of stay, healthcare costs, morbidity, and mortality. Studies that evaluate the role of urinary catheter design in preventing CAUTI are lacking. One such design is the double-balloon (DB) urinary catheter that has a second distal balloon; this design is aimed at reducing mucosal injury and inhibiting coiling of the in situ catheter. We carried out a comparative study to (a) determine whether CAUTI rates differ for different types of urinary catheters, and (b) identify risk factors associated with the acquisition of CAUTI in patients with DB vs. …

Distinct Effects Of Acute Versus Chronic Corticosterone Exposure On Zebra Finch Responses To West Nile Virus, Lynn B. Martin, Meredith E. Kernbach, Thomas R. Unnasch
Internal Medicine Faculty Publications
Wild animals are exposed to both short- (acute) and long-term (chronic) stressors. The glucocorticoid hormones, such as corticosterone (CORT), facilitate coping with such stressors, but these hormones can have quite distinct effects contingent on the duration of their elevation. Previously, we found that experimental elevation of CORT for 2 days (via implantation) affected zebra finch (Taeniopygia guttata) responses to West Nile virus (WNV). CORT-elevated birds had higher viremia for at least 2 days longer than controls, and West Nile virus (WNV)-associated mortality occurred only in CORT-elevated birds. Here, we queried how acute elevations of CORT, via injection an …

Infectious Complications In Adult Leukemic Patients With Prolonged Neutropenia Undergoing Induction Chemotherapy, Vidhya Sabapathy, Olga Klinkova, Joseph Balbona, John Greene
Internal Medicine Faculty Publications
Background: Induction chemotherapy in patients with the diagnosis of acute leukemia is associated with a high incidence of infectious complications. While prior studies provide information regarding infectious complications in this patient population, more research is needed to evaluate infection complications in a subgroup of leukemic patients with prolonged neutropenia who often require repeat induction chemotherapy.
Methods: This was a retrospective analysis of 61 patients ages 18–85, between January 1, 2010 and March 14, 2018 who were diagnosed and being treated for acute leukemia. All selected patients experienced severe neutropenia (defined as absolute neutrophil count <500/μL) for ≥7 days. 33 patients underwent their first induction chemotherapy while 28 patients underwent repeat induction chemotherapy. Patient characteristics and infectious complications were examined. Analysis was performed to further study blood stream infections in this patient population.
Results: Sixty-one patients, mean age of …

Predictors Of Recurrent Infective Endocarditis In Intravenous Drug Users, Kullatham Kongpakpaisarn, Sadaf Aslam, Musaab Tariq, Rahul Mhaskar, Doosup Shin, Chandrashekar Bohra, Charurut Somboonwit
Internal Medicine Faculty Publications
Background: Caring for hospitalized patients with infective endocarditis (IE) can be challenging due to the nature of the disease and its complications, underlying medical and psychiatric problems, socioeconomic status and environmental factors.Some of these patients develop recurrent IE after the first episode treated. On-going intravenous (IV) drug use after hospital discharge is the highest predictive factor for recurrent IE. Besides IV drug use, there are limited data of other contributing factors to recurrent IE. Those factors may be modifiable during the first hospitalization to reduce the incidence of recurrent IE.
Methods: A retrospective cohort study was conducted at a large …

Are Microclimate Conditions In El Malpais National Monument Caves In New Mexico, Usa Suitable For Pseudogymnoascus Growth?, Terry J. Torres-Cruz, Porras-Alfaro, Nicole A. Caimi
KIP Articles
White-nose syndrome (WNS) is a bat disease caused by the fungal pathogen Pseudogymnoascus destructans, which thrives in cold and very humid environments where bats frequently hibernate. Conidia of Pseudogymnoascus species are often documented on bats prior to the onset of WNS, but characterization of high-risk areas defined by microclimate cave conditions have been lacking. Investigating the occurrence of this fungal genus and appropriate environmental conditions to support P. destructans in southwestern U.S. caves is key to understanding the sites most likely to be impacted by WNS. Microclimate conditions in ten caves at El Malpais (ELMA) National Monument in New Mexico, …

Marine Science Faculty Publications
This paper examines the structure and dynamics of the marine ecosystem surrounding Haida Gwaii (an archipelago in the southeastern Gulf of Alaska). Based on previous research, a set of improved mass-balanced models was constructed in Ecopath with Ecosim (EwE) to represent ecosystem states existing circa 1900, 1950, and currently. These models feature increased taxonomic and ecological resolution relative to their predecessors across trophic levels and size classes from zooplankton to whales. A more detailed representation of Pacific herring (Clupea pallasii), including its age structure, predators, and prey, was introduced to permit modeling of the ecosystem role of herring …

Ifi16, A Nuclear Innate Immune Dna Sensor, Mediates Epigenetic Silencing Of Herpesvirus Genomes By Its Association With H3k9 Methyltransferases Suv39h1 And Glp, Arunava Roy, Anandita Ghosh, Binod Kumar, Bala Chandran
Molecular Medicine Faculty Publications
IFI16, an innate immune DNA sensor, recognizes the nuclear episomal herpes viral genomes and induces the inflammasome and interferon-β responses. IFI16 also regulates cellular transcription and act as a DNA virus restriction factor. IFI16 knockdown disrupted the latency of Kaposi’s sarcoma associated herpesvirus (KSHV) and induced lytic transcripts. However, the mechanism of IFI16’s transcription regulation is unknown. Here, we show that IFI16 is in complex with the H3K9 methyltransferase SUV39H1 and GLP and recruits them to the KSHV genome during de novo infection and latency. The resulting depositions of H3K9me2/me3 serve as a docking site for the heterochromatin-inducing HP1α protein …
