Introduction: Leptospirosis is considered the most widespread zoonosis in the world. It is typically transmitted through direct contact of the skin and mucous membranes with urine, blood, and other organic fluids contaminated by infected animals.
Aim: To present relevant data on dogs with acalculous cholecystitis as a relevant symptom in leptospirosis.
Methods: This study had a retrospective design. The data was collected from various private veterinary clinics in Asunción, Paraguay during the period from August 2022 to January 2023.
Results: The age range of the dogs analyzed ranged from 1 to 7 years. 4/6 were males, being able to adjudicate the predominance by sniffing habits and territorial behavior, which makes it more predisposing. The leukocyte count ranged from 7,900 to 16,200 cells/μl. Leukocytosis is the increase in the number of cells of the white blood series, indicating that there is an intense activity of the defenses against an infection of bacterial origin. In cases of acute leptospirosis, leukocytosis usually occurs in moderate or severe cases. However, in most of the cases that are oligosymptomatic or pictures similar to viral processes, the leukocytes usually have counts within normal limits; Likewise, it is common to see leukopenia in seriously ill patients or in patients with associated comorbidity.
Conclusions: It is important, in canine patients with non-specific symptoms accompanied by AAC symptoms, to include leptospirosis as a differential diagnosis, to implement adequate antibiotic treatment and avoid unnecessary surgical procedures.
