Results and discussion

Effect levels

Effect levels 1

Sex:

female

Dose descriptor:

LD50

Effect level:

> 300 mg/kg bw

Based on:

test mat.

Effect levels 2

Sex:

female

Dose descriptor:

LD50

Effect level:

< 2 000 mg/kg bw

Based on:

test mat.

Mortality:

In the 2000 mg/kg test group two animals were found dead on study day 8 or 9 after administration. Due to the high weight loss, the remaining animal of this test group was sacrificed in a moribund state on study day 9. No mortality occurred in the 300 mg/kg test groups.

Clinical signs:

other: In the animals of the 2000 mg/kg bw test group, impaired general state, dyspnoea, piloerection, reduced feces, and exsiccosis were noted from study day 2 or 3 onwards. In the animal that was sacrificed moribund, poor general state and cachexia were noted

Gross pathology:

In the animals that died Peyer’s plaques in the small intestine (one animal) and swollen lymph nodes in region of the small intestine and red discoloration of the small intestine in the second animal. In the animal that was sacrificed moribund swollen lymph nodes in region of the small intestine and red discoloration of the small intestine were also observed.

There were no macroscopic pathological findings in the surviving animals sacrificed at the end of the observation period (300 mg/kg, 6 females).
