Effect of 3-Phenylpropanoic Acid on Capsule and Cellulases of Ruminococcus albus 8.

abstract：:Infections caused by Toxoplasma gondii are widely prevalent in animals and humans throughout the world. In the United States, an estimated 23% of adolescents and adults have laboratory evidence of T. gondii infection. T. gondii has been identified as a major opportunistic pathogen in immunocompromised individuals, in ...
