Zarnoch Studies The Health Of Our Waters, Aldemaro Romero Jr.

Publications and Research

Some people look at scientists and think of them as narrowly focused on obscure issues, but that is not the case with Dr. Chester Zarnoch. “You’re not just exploring the biology and the chemistry associated with the problem you’re working on, but also thinking about social implications, about economic implications,” he says.

A native of Manhattan, Zarnoch has studied and worked his entire life in New York, from receiving his bachelor’s degree at Southampton College of Long Island University, his master’s in the philosophy of biology at the City University of New York (CUNY) Graduate Center, a master’s in biology …

Accumulation And Expression Of Multiple Antibiotic Resistance Genes In Arcobacter Cryaerophilus That Thrives In Sewage, Jess A. Millar, Rahul Raghavan

Biology Faculty Publications and Presentations

We explored the bacterial diversity of untreated sewage influent samples of a wastewater treatment plant in Tucson, AZ and discovered that Arcobacter cryaerophilus, an emerging human pathogen of animal origin, was the most dominant bacterium. The other highly prevalent bacteria were members of the phyla Bacteroidetes and Firmicutes, which are major constituents of human gut microbiome, indicating that bacteria of human and animal origin intermingle in sewage. By assembling a near-complete genome of A. cryaerophilus, we show that the bacterium has accumulated a large number of antibiotic resistance genes (ARGs) probably enabling it to thrive in the wastewater. We also …

Gosnell Studies And Communicates Ecological Concerns, Aldemaro Romero Jr.

Publications and Research

Scientists who study environmental problems know that the more you work in the field, the more insight you gain into how to solve problems. In other words, the more field experience you have, the deeper your understanding of nature.

One scientist who has had a lot of field experience is Dr. Stephen Gosnell, and his interest in the environment began when he was still a child. “I had interest really early. I grew up in rural South Carolina in a very small town called Landrum. I was outside on a regular basis, playing in the streams and creeks around me,” …
