Viruses that infect eukaryotic cells typically bind to a plasma membrane receptor to initiate the reproduction cycle. Attachment of bacteriophages to bacterial cells is more diverse. Some attach to bacterial outer membrane proteins, while others attach to appendages such as pili or flagella. How viruses move from the flagella to the bacterial cell surface is …
with Amy Rosenfeld Enterovirus D68 (EV-D68) was first isolated from children with respiratory disease in 1962. No outbreaks of infection were detected until the late summer and early fall of 2014, and then in 2016 and 2018. During these epidemics of respiratory disease, some children developed polio-like paralysis. We have recently published a paper showing …

Today, on World Polio Day, wild poliovirus type 3 has been declared eradicated by a commission of the World Health Organization. The last case of type 3 poliomyelitis was recorded in 2012 in Nigeria. Because wild poliovirus type 2 was declared eradicated in 2015, now only wild poliovirus type 1 continues to circulate, causing paralysis …
Viruses and bacteria are both present at mucosal surfaces and it is not surprising that they interact in many ways. Sometimes members of the gut microbiome help viruses to infect cells, exemplified by poliovirus, reovirus, and mouse mammary tumor virus. The opposite also happens: segmented filamentous bacteria can prevent and cure rotavirus infection.

Cases of poliomyelitis have been reported in the Philippines 19 years after the country was declared free of the disease. The return of poliomyelitis to the country emphasizes the need to maintain high levels of immunization while polioviruses continue to circulate.
