Due to slightly higher variability in female mouse behavior, likely due to higher levels of pathology [19], we performed all other experiments exclusively with males. (journals.plos.org)
Due to the variety of generalized pathology and since detailed studies of Type II infection as it relates to mouse behavior exist elsewhere, we did not continue investigations with Type II parasites. (journals.plos.org)
Some aspects of mouse behavior improved, too. (sciencedaily.com)
