Right cervical lymph node: The lymph node is enlarged and has a preserved architecture with a thin capsule and open sinuses.

The study determined that at times, an infected wolf would become the only breeding male in a pack,[118] leading to a significant effect on another species by "T. gondii. [98] Looking at humans, studies using the Cattell's 16 Personality Factor questionnaire found that infected men scored lower on Factor G (superego strength/rule consciousness) and higher on Factor L (vigilance) while the opposite pattern was observed for infected women.
