Changes in Leukogram and Erythrogram Results in Bitches with Vaginitis

SIMPLE SUMMARY: Inflammatory diseases of the reproductive tract of bitches are a common problem in veterinary practice. Vaginitis, which is an inflammation of the vagina, may have various causes and degrees of severity. The aim of this study was to analyze whether the inflammation of the vagina in dogs causes changes in the parameters of white blood cells (leukogram, which is the percentage of individual types of white blood cells) and red blood cells (erythrogram, changes in the shape of erythrocytes). The obtained results suggest that leukogram and erythrogram analyses may be useful diagnostic tools in veterinary practice. ABSTRACT: Vaginitis in female dogs is a problem most veterinarians face in their practice. It manifests as localized inflammation, and its variable etiology and different severities often make diagnosis problematic. The study consisted of comparing blood smears taken from 16 animals: 8 healthy bitches and 8 bitches with confirmed vaginitis. We analyzed the percentage of different types of white blood cells (leukogram) and changes in the shape of red blood cells (erythrogram) in both groups. We observed changes in red blood cell morphology, i.e., a higher percentage of lacrimocytes and schistocytes in female dogs with vaginitis compared to their healthy counterparts. The observed hematological changes may illustrate the severity of inflammation. The analysis of erythrograms showed a significantly higher percentage of lacrimocytes and schistocytes in diseased bitches (1.58 ± 1.19% and 0.13 ± 0.12%) compared to healthy animals (0.58 ± 0.38 and 0.00 ± 0.00, respectively). The obtained results may indicate that the analysis of erythrograms throughout the course of vaginitis in bitches may constitute a diagnostic tool, as opposed to the analysis of leukograms, which is more sensitive when it comes to the systemic inflammatory response of the organism. It seems that simultaneous analysis of erythrograms and leukograms may facilitate the diagnostic process in clinical practice.
