Health Status of Male Adult Wistar Rats from Two Experimental Animal Houses of UFMG: Leukocyte Counts, Feces and Lung Histological Exams

A study was conducted to compare health status of male adult Wistar rats from two Experimental Animal Houses of UFMG with literature data of SPF (free from specific pathogens) and conventional rats. The animals were divided into two groups: Group I (n=10), rats from the experimental animal houses of FAFICH and Group II (n=10) from ICB and following aspects were studied: a) evident clinical signs (behavior modification, hair loss (alopecia), b) leukocyte counts, c) feces exam and d) histological study of the lungs. The rats did not show clinical signs. However, when compared with SPF and conventional rats, both the groups showed a significant increase (p<0,05) of leukocyte count. On feces exam we detected some parasites and on lung histological exam we observed fungus (Group I) and bacteria (Group II). These results showed that the health status of the rats was not satisfactory and required improvements in the conditions of the animal houses.
