The importance of morphological changes in neutrophils in the diagnosis of bacterial infections in dogs with confirmed urinary tract infections in a Veterinary Care Service, Rio de Janeiro, Brazil.

Neutrophils (PMNs) are cellular markers used for diagnosing inflammation and/or infections. In this study, the objective was to highlight the importance of recording the toxic morphological alterations of the PMNs as markers of infection in 10 cases, positive bacterial isolation by culture due to dysuria, hematuria and/or fetid urine, as manifestations of urinary tract disease. Smear observations were performed by immersion for counting and morphological evaluations of 3,000 leukocytes in smears and in leukocyte concentrate.

Assessment of some clinical and laboratory variables for early diagnosis of cumulative copper poisoning in sheep.

Sixteen male Suffolk lambs fed a 8 ppm Cu basal diet were randomly assigned to 2 groups: 12 copper-loaded (CL) and 4 controls (C). The CL sheep were drenched initially with 3 mg Cu/kg bw daily for a week. Every week an additional dose of 3 mg Cu/kg bw was included in the drench until signs of copper poisoning appeared; the control sheep were drenched with saline solution.
