Isolation of viable Toxoplasma gondii from organs and Brazilian commercial meat cuts of experimentally infected pigs

The present study evaluated the distribution and viability of Toxoplasma gondii tissue cysts in the organs and Brazilian commercial cuts of experimentally infected pigs. The pigs were infected with 3 × 10 3 oocysts of the T. gondii isolate TgCkBr57 (Type BrII). Mouse bioassays were performed on the...

Description
Summary:The present study evaluated the distribution and viability of Toxoplasma gondii tissue cysts in the organs and Brazilian commercial cuts of experimentally infected pigs. The pigs were infected with 3 × 10 3 oocysts of the T. gondii isolate TgCkBr57 (Type BrII). Mouse bioassays were performed on the brain, retina, tongue, diaphragm, and heart as well as the following muscle cuts: loin ( longissimus ), coppa ( longissimus , spinalis dorsi , rhomboideus ), tenderloin ( psoas major ), outside flat ( biceps femoris ), topside ( semimembranosus ), and top sirloin ( gluteus medius ). Toxoplasma gondii was isolated from the coppa, heart, diaphragm, and tongue of three pigs; from the tenderloin, outside flat, and brain of two pigs; and from the top sirloin and loin of one pig. Thus, the viability of T. gondii cysts was observed in all of the organs and cuts evaluated (except for the topside and retina), demonstrating the broad distribution of this parasite in pig organs and commercial meat cuts, and the importance of this species as a source of human infection.
