Investigation of anti-Leptospira spp. antibodies and leptospiruria in cats attended to a veterinary teaching hospital in southern Brazil.

Leptospirosis is a bacterial zoonosis that affects both humans and animals worldwide. Currently, it is known that cats may be susceptible to infection. This study aims to investigate the presence of anti-Leptospira spp. antibodies and leptospiruria in cats, using Microscopic Agglutination Test (MAT) and Real-time Polymerase Chain Reaction (PCR) techniques, respectively. A total of 76 cats, undergoing comprehensive anamnesis, general physical examination, and complementary exams were included in the investigation. Among the 76 cats tested, 9.2% (7/76) exhibited the presence of anti-Leptospira spp. antibodies, while Leptospira spp. DNA was detected in at 1.3% (1/76) of the evaluated urine samples. No significant associations were observed between the serological and molecular diagnostic results and the assessed variables, including clinical data and laboratory results of cats testing positive. This study provides insight into the occurrence of Leptospira spp. infection and leptospiruria in cats treated at a veterinary teaching hospital in southern Brazil.

Laryngeal Paralysis Following Endotracheal Intubation in a Dog: A Case Report.

The occurrence of laryngeal paralysis following endotracheal intubation in dogs is rare. A one-year-old canine was presented with aspiration pneumonia in the postoperative period following general anesthesia for acetabular denervation surgery. After a month of treatment for aspiration pneumonia, the patient had inspiratory stridor and dyspnea, and the diagnosis of unilateral laryngeal paralysis was made through laryngoscopy. Along with the benefits of endotracheal intubation come many risks. Laryngeal paralysis can be a serious complication, predisposing the patient to aspiration. This report is the second in veterinary medicine to describe laryngeal paralysis as a possible complication after endotracheal intubation in a dog.
