Arthrogryposis Multiplex Congenita due to Toxoplasma gondii Infection in a Newborn Calf

Arthrogryposis Multiplex Congenita (AMC) includes various conditions of unclear etiology but in general anycause of reduced fetal movement may result in congenital contractures. Neurologic abnormalities appear as themost common causes of AMC (approximately 70% to 80% of all cases). This paper describes a case of clinicalcongenital toxoplasmosis in a newborn calf and suggests that the protozoan Toxoplasma gondii may also beresponsible for AMC. In fact, a central nervous system involvement appears to be present in most cases of AMCand in this case the presence of Toxoplasma gondii in calf's brain was demonstrated through molecular biologyexamination and immunohistochemistry analysis
