Adenovirus

Adenoviruses, of which there are over 50, can cause a variety of illnesses ranging from mild respiratory disease, to very painful eye infections, diarrheal illnesses, rashes, and even life-threatening infections in those who are immune compromised. The number of cases of Adenovirus infection are not regularly tracked since many cases will go undiagnosed, but these infections are considered to be very common throughout the life span, although they may be more common in younger people as they would be less likely to have prior exposure and any level of immunity. Adenovirus infections cause significant lost days of work and school and are certainly an infection worth preventing.

Vibrio

Vibrio is a genus of bacteria that includes several species that are important causes of human disease. The most infamous of these diseases is caused by Vibrio cholerae, which causes cholera. Other significant species causing illness in humans are Vibrio vulnificus and Vibrio parahaemolyticus. Globally, these infections sicken many people and are sometimes fatal.

Shigella

Shigella is a genus group of bacteria that contains four species, S. dysenteriae, S. flexneri, S. boydii, and S. sonnei.  While these are frequently referred to as “species,” it is probably more scientifically correct to refer to them as biotypes of Escherichia, but because of the important medical differences between infections with Shigella versus most …

Escherichia

Escherichia Basics Escherichia is the genus name of a group of bacteria that contains at least 7 different species, although by far the most well-known and well-studied is clearly Escherichia coli (E. coli).  Because E. coli is so common in the environment and in humans, as well as in other animals and because it is …

Enterococcus

Enterococcus is the genus name of a group of bacteria that contains about 20 different species that have been implicated in human disease at some point.  However, the overwhelming majority of such infections result from Enterococcus faecalis (E. faecalis) with most all of the remaining infections being accounted for by Enterococcus faecium (E. faecium).  The …

Enterobacter Species

Enterobacter Basics Enterobacter is the genus name of a group of bacteria consisting of between 12 and 14 species that are known to potentially cause disease in humans, although other Enterobacter species (sp) certainly exist in the environment without causing any known infections in any other organism.  Enterobacter species are generally members of what is …
