Haematochemical Profile of Healthy Dogs Seropositive for Single or Multiple Vector-Borne Pathogens.

BACKGROUND

the present study aimed to investigate the immunological response to common vector-borne pathogens and to evaluate their impact on haematochemical parameters in owned dogs.

METHODS

Blood samples were collected from 400 clinically healthy dogs living in an endemic area (Sardinia Island, Italy). All dogs were serologically tested for VBDs and divided into groups based on their negative (Neg) or positive response towards Ehrlichia (Ehrl), Rickettsia (Rick), Leishmania (Leish), Borrelia (Borr), Anaplasma (Anapl), and Bartonella (Barto). A Kruskall-Wallis's test, followed by Dunn's post hoc comparison test, was applied to determine the statistical effect of negativity and single or multiple positivity on the studied parameters.

RESULTS

the group of dogs simultaneously presenting antibodies towards Leishmania, Ehrlichia, and Rickettsia showed higher values of total proteins, globulins, creatine phosphokinase, aspartate aminotransferase, alanine aminotransferase, and amylase than dogs that tested negative or dogs with antibodies toward a single pathogen investigated herein.

CONCLUSIONS

Our results seem to suggest that exposure to more vector-borne pathogens could lead to greater liver function impairment and a greater inflammatory state. Further investigations are needed in order to better clarify how co-infections affect haematochemical patterns in dogs living in endemic areas of VBDs.
