Southern Ontario

Using the haematocrit centrifuge technique, 53 of 619 small mammals from seven areas in southern Ontario were found to be infected with three species of trypanosomes. Trypanosoma microti was found in 10 of 374 (2.7%) Microtus pennsylvanicus examined from two of five locations. Thirty-five of 102 (34%) of Tamias striatus from one area were infected with Trypanosoma tamiasi and over 94% (33 of 35) of the infected animals were juveniles. This would indicate that the trypanosome is primarily a parasite of juveniles. A trypanosome which was tentatively identified as Trypanosoma soricis was found in 8 of 36 (22%) Blarina brevicauda; it was recorded from two of four areas where the shrews were caught. A detailed description of the trypanosome was given because the original description was inadequate. No trypanosome was found in 74 Peromyscus maniculatus, 31 Mus musculus, and 2 Zapus hudsonius examined.

Adult Mice

The present investigation compares performance and learning of 3 groups of adult mice: Mus musculus (wild and C57BL/6J) and Peromyscus maniculatus Bairdii on 2 types of water maze (spatial or visual) under 4 levels of motivation (55, 75, 95, or 115°F water temperature). The wild Mus learned most rapidly, the Peromyscus being the slowest to learn. Extremes of water temperature and the spatial discrimination task facilitated performance and learning.

As If

1. Antigenic polymorphism between individuals of the subspecies Peromyscus maniculatus gracilis is demonstrated.2. Absorption analysis of heteroimmune rabbit sera using erythrocytes of individual mice revealed two unitary complete (saline) agglutinins, designated as anti-A and anti-B, reactive to erythrocytic antigens in this species.Isoimmunization apparently demonstrated these same antigenic differences.3. The two antigenic characters (A and B) defined by the agglutinins are inherited as if simply related to allelic factors designated PmA and PmB respectively.4. These two antigens are found in representatives of both the subspecies P. m. gracilis and P. m. bairdii, and, in addition, the A antigen was observed in a laboratory stock of P. polionotus. Tested individuals of the species P. leucopus and Mus musculus, however, possessed neither antigen, and samples of human blood also lacked both antigens.5. Species-specific agglutinins distinguishing individuals of the species P. leucopus and P. maniculatus, and population-specific agglutinins which distinguished between individuals of the subspecies P. m. bairdii and P. m. gracilis, have been observed.

ZusammenfassungEs werden die Fälle einer disseminierten letalen Toxoplasmose bei einer Farbmaus (Mus musculus) und einem Roten Panda (Ailurus fulgens) vorgestellt. Es handelte sich um eine als Haustier gehaltene Farbmaus und einen Roten Panda aus einem sächsischen zoologischen Garten. Die pathologische Untersuchung ergab bei beiden Tieren eine systemische Toxoplasmeninfektion. Eine hochgradige nekrotisierende Hepatitis stellte in beiden Fällen den histologischen Hauptbefund dar. Parasitenzysten fanden sich massenhaft in der Leber, in mäßiger Zahl im Gehirn und in geringer Zahl in anderen Organen. Mittels PAS-Reaktion waren diese Zysten bei der Farbmaus kaum darstellbar, beim Roten Panda dagegen sehr deutlich. PCR bzw. Immunhistologie bestätigten die Diagnose.
