Multiple cases of Strep Zoo at the Colorado Springs animal shelter. They have a robust plan in place to ensure that they contain this bacterium that impacts dogs.
In many cases, dogs pass away from this infection, however, they have not experienced this.
Streptococcus Equi Subsp Zooepidemicus, also known as Strep Zoo, is a bacterium that is commonly found in horses, cattle, and pigs and rarely causes disease in these animals. Because it is zoonotic, it can be transmitted between animal species and (rarely) humans. When it affects dogs, it is highly contagious and can cause severe respiratory disease. It is a relatively new pathogen present in animal shelters and there are still many things they do not know about this bacterium.
Strep zoo is transmitted primarily by direct contact, contact with contaminated fomites and by inhalation. It can also be spread during the sanitation process and survives in wet environments.
This bacterium is effectively killed by deep cleaning, scrubbing, and power washing surfaces.
