Mycoplasma suis detection test kit by using qPCR. Mycoplasma suis (formerly known as Eperythrozoon suis) is the most prevalent agent causing hemolytic anemia in swine, which is characterized by listlessness, fever, anorexia, hemolytic anemia, and, in severe cases, icterus. M. suis can cause acute disease, but the major significance of their infections lies in the fact that M. suis can establish chronic and persistent infections leading to a higher susceptibility to other infections, especially in the respiratory and digestive tracts.
