Yes, cats typically carry Toxoplasma gondii for life once infected, but the parasite remains in a dormant state within the cat’s tissues, forming cysts. These cysts usually do not cause harm or reactivate in a healthy cat. After the initial infection, cats develop immunity and rarely shed the parasite again.
Ringbio’s Feline Toxoplasma IgG Antibody ELISA Kit is based on an enzyme-linked immunosorbent assay to detect toxoplasma specific antibodies in feline serum and plasma, moreover, it can be used in the evluation of toxoplasma infection in cats. The kit requires no special equipment and results are visible within 70 minutes.
