Breaking the Silence: Interaction of Acinetobacter sp. RIT 592 induces the production of broad-spectrum antibiotics in Exiguobacterium sp. RIT 594
Monday, October 21
1:00 - 1:50 PM
Gosnell A300
André Hudson, Ph.D.

Antimicrobial resistance (AMR) is one of the most alarming global public health challenges of the 21st century. Over 3 million antimicrobial-resistant infections occur in the United States annually, with nearly 50,000 cases being fatal. Innovations in drug discovery methods and platforms are crucial to identify novel antibiotics to combat AMR. We present the isolation and characterization of potentially novel antibiotic lead compounds produced by the cross-feeding of two rhizosphere bacteria, Acinetobacter sp. RIT 592 and Exiguobacterium sp. RIT 594. The supernatant from RIT 592 induced RIT 594 to produce a cocktail of antimicrobial compounds active against Gram-positive and negative bacteria. This work emphasizes the utility of microbial community-based platforms to discover novel clinically relevant secondary metabolites.

Combining isotopic and molecular approaches to understand patterns of methane emissions across high latitude peatlands
Monday, November 4
1:00 - 1:50 PM
Gosnell A300
Carrie McCalley, Ph.D.
Associate Professor
Thomas H. Gosnell School of Life Sciences
Rochester Institute of Technology
A challenge for improving future climate predictions is to develop an understanding of the sinks and sources of methane (CH4). High latitude ecosystems are a large source of atmospheric CH4 and are undergoing rapid change. One solution for identifying drivers of changing atmospheric CH4 has been to use tropospheric observations of CH4 concentration and isotopic signature to attribute changes in atmospheric CH4 to specific sources and regions. We characterized methane cycling microbial communities and associated CH4 isotope biogeochemistry from well-studied high-latitude peatlands across North America and Scandinavia, including sites with well documented habitat shifts associated with permafrost thaw.

Parents, porches, and Pb policy: Cycles of engagement and research

Childhood lead poisoning remains a global environmental health threat. However, effective, efficient, equitable solutions differ from place to place. Rochester’s 2005 lead law is hailed as a ‘gold standard’ for preventing housing-based exposures to lead. This talk will explore how ongoing interactions between researchers, community groups, and government over 25 years have contributed to rapid declines in childhood lead poisoning in Rochester while contributing to federal policy and setting a national model for locally-based primary prevention.

Microbiological predictive modeling for food safety risk assessment: State of the art and way forward
Nurul Hawa Ahmad '10, Ph.D.
Senior Lecturer
Food Science and Technology
Universiti Putra Malaysi
Predictive modeling can be described as mathematical expressions that reflect the growth, survival, or inactivation behaviors of foodborne pathogens under certain conditions. When kinetic parameters of microbial behaviors can be estimated, this information is valuable as scientific evidence to support risk-based decision making in food safety. This talk will cover concepts of predictive modeling, available web-based tools, and the roles of predictive modeling in food safety risk assessment. This talk will also discuss our works inactivation and growth of foodborne pathogens in selected food commodities as well as future recommendations for predictive modeling in food safety.
A bubbling cauldron of antibiotic resistance: Commensal Neisseria, a persistent threat for DNA donation to important human pathogens
Crista Wadsworth, Ph.D.
Assistant Professor
Thomas H. Gosnell School of Life Sciences
RIT
Alongside the crisis of antimicrobial resistant gonorrhea is the threat of bystander selection on commensal Neisseria. As Neisseria species are all permissive to gene flow across lineages, their evolutionary fates are irrevocably intertwined. Current projects in the Wadsworth Lab focus on defining the Neisseria resistome, or all available resistance mechanisms present in the genus. We will discuss past and ongoing experimental evolution, population genomics, and experimental work all focused on elucidating the mechanisms of resistance in commensals, and how they have transmitted between Neisseria populations.
Can I Borrow a Gene?
Fernando Rodriguez, Ph.D.
Research Scientist
Thomas H. Gosnell School of Life Sciences
RIT
Bdelloid rotifers are microscopic freshwater invertebrates able to survive desiccation and to reproduce asexually. The genome of the bdelloid rotifer Adineta vaga is unusual in having over 8% of its genes originated from non-metazoan (predominantly bacterial) sources. This suggests that genetic and epigenetic mechanisms play a crucial role in maintaining genome stability. My research proposes that bdelloid rotifers not only effectively regulate the integration of foreign genes acquired at a high rate, but also uniquely "borrow" both simple and complex genes, harnessing them for their own advantage.

As part of the program, Hannah traveled to norther Sweden to perform vegetation assessments and collect pore water samples in an area of permafrost transition/thaw. Her results showed considerable change in vegetation cover, pH, and methane concentrations between 2015 and 2023.
- Sydney Purcell conducted research at RIT in Dr. Ferran's viral genetics lab. She focused on using targeted molecular imaging agents to image breast cancer cells and infecting C. elegans with VSV to overexpress a specific gene. Zak Azad conducted research in Dr. Thomas' lab at RIT. The research project focused on optimizing parameters that impact phage growth and yield.
- Tori Russell was involved in several research projects in Dr. Ferran's lab at RIT, including a mechanobiology project, a breast cancer imaging project, and a C. elegans/VSV project.
- Maggie Muldoon participated in the RIT Wetlands REU, with her research project focusing on the impact of the Emerald Ash Borer on bird species and habitat in forested wetlands.
Part 1
- Natalie Siwek completed a co-op with VHB, a company that specializes in civil engineering, urban planning, and environmental consulting. She supported the Natural Sciences team by assisting with wetland delineations, rare species surveys, construction compliance inspections, permit application preparation, and data collection and synthesis.
- Leah Robinson was part of an NSF EFRI REM program in the Material Science and Engineering Department at the University of Michigan, researching how organic vapor jet printed active pharmaceutical ingredients impacted the cell growth and viability of ovarian cancer cell spheroids.
