Infection with influenza virus is known to increase susceptibility to bacterial infections of the respiratory tract. In a mouse model of influenza, increased bacterial colonization was also observed after administration of an infectious, attenuated influenza virus vaccine. Primary influenza viru... Read More

The time before the symptoms of a viral infection appear is called the incubation period. During this time, viral genomes are replicating and the host is responding, producing cytokines such as interferon that can have global effects, leading to the classical symptoms of an acute infection (e.g....

Wild poliovirus has been detected in the sewers of Brazil and Israel. Fortunately, no cases of poliomyelitis have been reported in either country. Why is poliovirus present in these countries and what are the implications for the eradication effort?
Wild type poliovirus (e.g. not vaccine-deri... Read More

Middle Eastern respiratory syndrome coronavirus (MERS-CoV), first identified in the fall of 2012 in a Saudi Arabian patient, has since infected over 160 individuals, causing 71 deaths. Identifying the source of infection is important for efforts to prevent further infections. Recently two studie... Read More
Until recently cancers were seen as lifestyle and genetic diseases, brought on by exposure to carcinogens or a mutated gene. Recent studies are linking microbes to many diffe... Read More
The journal "RNA Biology" just published a memorial issue dedicated to the late, great Carl Woese. The entire issue is open access. I have a small contribution, but the entire issue is filled with great science, wonderful memories, and a fine celebration of a scientist who changed the way we l... Read More
Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution. T... Read More

In this blog post, I describe some "rules for academics" as well as my own "rules for research." I hope that readers find them useful and perhaps a bit humorous. Read More
PLOS ONE authors Cybulski, Clements and Prakash describe an ultra-low-cost origami-based approach for large-scale manufacturing of microscopes, specifically demonstrating brightfield, darkfield, and fluorescence microscopes. Merging principles of optical design with origami enables high-volume f... Read More
During the winter of 1962 in California, a new virus was isolated from the oropharynx of 4 children who had been hospitalized with respiratory disease that included pneumonia and bronchiolitis. On the basis of its physical, chemical, and biological properties, the virus was classified as an ente... Read More

A form of bacteria responsible for respiratory illness, including the deadly pneumonia known as Legionnaire's disease, may be able to grow in windshield washer fluid and was isolated from nearly 75% of school buses tested in one district in Arizona. The participant will discuss findings from ... Read More
Wine grapes present a unique biogeography model, wherein microbial biodiversity patterns across viticultural zones not only answer questions of dispersal and community maintenance, they are also an inherent component of the quality, consumer acceptance, and economic appreciation of a culturally ...

In this blog entry, I describe how working with the artist Katie McKissick ("Beatrice the Biologist") helped improve my freshman biology course. The intersection of biology and art benefits both! Read More
It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another r... Read More
