Comparative Evaluation of Biochemical Parameters During Urinary Infection in Maltese and Belgian Shepherd Dogs

Abstract Urinary tract infections can be uncomfortable, painful and even dangerous for most dog breeds. Clinical signs are often nonspecific and insufficient for diagnosis. Urinalysis in combination with biochemical parameters and urine culture is the best combination of clinical findings for diagnosis of urinary tract infections. The incidence of urinary tract infections in dogs population is growing and 27% of dogs develop an urinary tract infection through their life. Urinary infections occur more often in the elderly than in younger dogs. More than 70% of all urinary tract infections are infections with one bacterial species. Biochemical profile is important aspect for diagnosis establishment, but due to the nature of action infection by different agents may be considered as individual case. The main aim of this research was to analyse biochemical parameters of Maltese and Belgian Shepherd (Malinois) dog breed, who were affected by urinary tract infections. Urea concentration was elevated in Malinois, while urea, phosphates, albumins and alkaline phosphatase activity were elevated in Maltese dogs. Statistical analysis showed differences in concentrations of urea, creatinine, phosphates, so as alanine aminotransferase, alkaline phosphatase and amylase activity between compared breeds during acute urinary infections. Maltese dogs are less resistant to bacterias, that causes urinary tract infections, and have lower chance to maintain homeostasis of biochemical parameters in blood during urinary bacterial infections, in comparison to Maltese dogs.
