Microbiologists have cracked the case of Shedd Aquarium’s missing medicines

The Shedd Aquarium in Chicago partnered with microbiologists at Northwestern University to find out why chloroquine kept disappearing from the water in the quarantine habitat.

Founded in 1930, Chicago’s Shedd Aquarium is not just a popular tourist attraction. Its staff also aids in worldwide conservation efforts and conducts essential research on animal health and behavior, nutrition, genetics, aquatic filtration, and molecular and microbial ecology. Over the last four years, those staffers have been puzzled by the mysterious disappearance of an antiparasitic drug routinely added to the water in the aquarium’s quarantine habitat. Now, with the help of microbiologists at Northwestern University, they’ve cracked the case. The culprits: some 21 members of a family of microbes who were munching regularly on the medicine in the water, according to a recent paper published in the journal Science of the Total Environment.

The aquarium’s Center for Conservation and Research includes an Animal Care and Science Division, with a state-of-the-art animal hospital for monitoring the health of all the animals in the exhibits and treating them as necessary. (If you want to know how to give an electric eel an MRI, the center’s team has you covered.)

Since 2015, the center has been working on a special research project investigating aquarium microbiomes. Among other topics, the project involves studying microbial communities in aquarium bio-filters. Such closed aquatic systems can quickly become toxic, thanks to ammonia waste from the fish, and certain microbial communities can help keep those levels in check. But other microbes are less beneficial, as evidenced by the Case of the Missing Chloroquine.

“Vulture bees” evolved a taste for flesh—and their microbiomes reflect that

Jungle insects crawl over a hunk of pink flesh.

Ask a random person to picture a bee, and they’ll likely conjure up the familiar black-and-yellow striped creature buzzing from flower to flower collecting pollen to bring back to the hive. But a more unusual group of bees can be found “slicing chunks of meat from carcasses in tropical rainforests,” according to the authors of a new paper published in the journal mBio. As a result, these bees have gut microbiomes that are markedly different from their fellow buzzers, with populations more common to carrion-loving hyenas and vultures. So they are commonly known as “vulture bees” (or “carrion bees”).

According to the authors—entomologists who hail from the University of California, Riverside (UCR), the University of Massachusetts, Amherst, Columbia University, and the American Museum of Natural History—most bees are essentially “wasps that switched to a vegetarian lifestyle.” But there are two recorded examples of bumblebees feeding on carrion dating back to 1758 and 1837, and some species are known to occasionally feed on carrion in addition to foraging for nectar and pollen. (They are considered “facultatively necrophages,” as opposed to vulture bees, which are deemed “obligate necrophages” because they only eat meat.)

An entomologist named Filippo Silvestri identified the first “vulture bee” in 1902 while analyzing a group of pinned specimens, although nobody called it that since they didn’t know at the time that this species fed on carrion. Silvestri dubbed it Trigona hypogea, and he also described their nests as being used for honey and pollen, although later researchers noted a surprising absence of pollen. Rather, biochemical analysis revealed the presence of secretions similar to those fed to queen bees in the nests of honeybees.

Leonardo da Vinci’s drawings have unique microbiomes, study finds

Microbiomes are all the scientific rage, even in art conservation, where studying the microbial species that congregate on works of art may lead to new ways to slow down the deterioration of priceless aging artwork, as well as potentially unmask counterfeits. For instance, scientists have analyzed the microbes found on seven of Leonardo da Vinci’s drawings, according to a recent paper published in the journal Frontiers in Microbiology. And back in March, scientists at the J. Craig Venter Institute (JCVI) collected and analyzed swabs taken from centuries-old art in a private collection housed in Florence, Italy, and published their findings in the journal Microbial Ecology.

The researchers behind the earlier March paper were JCVI geneticists who collaborated with the Leonardo da Vinci DNA Project in France. The work built on a prior study looking for microbial signatures and possible geographic patterns in hairs collected from people in the District of Columbia and San Diego, California. They concluded from that analysis that microbes could be a useful geographic signature.

For the March study, the JCVI geneticists took swabs of microbes from Renaissance-style pieces and confirmed the presence of so-called “oxidase positive” microbes on painted wood and canvas surfaces. These microbes munch on the compounds found in paint, glue, and cellulose (found in paper, canvas, and wood), in turn producing water or hydrogen peroxide as byproducts.
