Synthesis and Distribution of CARDS Toxin During Mycoplasma pneumoniae Infection in a Murine Model

Mice were infected with Mycoplasma pneumoniae and monitored for the synthesis and distribution of the unique adenosine diphosphate-ribosylating and vacuolating Community Acquired Respiratory Distress Syndrome (CARDS) toxin in bronchiolar lavage fluid (BALF) and lung. We noted direct relationships between the concentration of CARDS toxin and numbers of mycoplasma genomes in BALF and the degree of histologic pulmonary inflammation. Immunostaining...
