SUMMARY

Trabecular bone remodeling values of the right and left iliac crest and lumbar vertebrae in cats were quantitated histomorphometrically and were compared. Healthy cats were given calcein (n = 2) or oxytetracycline (n = 2) twice for double-labeling of bone. Static and dynamic variables of bone resorption and formation were determined. Bone remodeling variables between right and left iliac crest were not significantly different (P < 0.05). Significant differences (P ≤ 0.05) were not detected between values of iliac crest and lumbar vertebrae except in the percentage of osteoid surface. Percentage of osteoid surface was significantly (P ≤ 0.05) increased in the iliac crest compared with that in the vertebral body. Although not significantly different, values for bone formation were generally greater in the iliac crest than in the vertebral body. In healthy cats, values of trabecular bone remodeling were comparable between right and left iliac crest, and also were comparable between iliac crests and lumbar vertebrae.

Summary

Approximately 10 of 100 young heifers that had recently delivered their first calf—members of a large Colorado dairy herd—had a syndrome of swollen teats and distal portions of the hind limbs, prefemoral lymphadenopathy, transient fever, rough coat, decreased milk production, and subsequent weight loss and reproductive inefficiency. Acute clinical signs of disease were associated with large numbers of Eperythrozoon wenyonii seen on blood smears, and resolution of signs correlated with reduction or disappearance of the parasite. Other known causes of peripheral edema could not be documented. The parasite was transmitted to 4 of 7 nonlactating dairy cows destined to be culled and a splenectomized calf via IV inoculation of blood from parasitemic heifers, but clinical signs of infection were not induced.
