Cistite canina causada por Salmonella enterica subsp. enterica / Canine cystitis caused by Salmonella enterica subsp. enterica

ABSTRACT

Background: Urinary tract infection in dogs is usually associated with the presence of bacteria, with a higher prevalenceof Gram-negative bacteria, represented mainly by enteric bacteria such as Escherichia coli and Proteus spp., followed byGram-positive bacteria such as Staphylococcus spp., and Streptococcus spp. There are scant reports of Salmonella spp.as the causative agent of urinary tract infection in dogs. Indeed, the literature describes only a few cases, most of whichinvolve the isolation of these bacteria in feces. This paper reports a case of canine cystitis caused by Salmonella entericasubsp. enterica in the northeast region of Brazil.Case A female dog of the Fila Brasileiro breed, about 9 year-old, wormed but unvaccinated, was evaluated at the Veterinary Hospital of the Federal University of Pernambuco - UFRPE. The dog showed clinical signs of apathy, cachexia,polyphagia, polyuria and opacity of the crystalline lens. The dog’s owner stated that the animal was fed with commercialdog food. In the clinical exam, the patient presented pale mucosa, cachexia, absence of ectoparasites, and her rectal temperature was 39.5°C. Moreover, cardiorespiratory auscultation of the patient revealed tachycardia (190 bpm) and tachypnea (36 bpm). The owner’s main complaint was the clinical condition of frequent urination (polyuria). A urinalysis andurine culture with antibiogram were requested as complementary exams, after collecting the urine by cystocentesis. Thevolume obtained in the physical examination of urinalysis was 7 mL of yellow urine with a putrid smell, cloudy appearance and density of 1.024. The chemical examination revealed pH 6.5, protein (+++), bilirubin (+), normal urobilinogenand negative reactions for glycoses, ketone, nitrite and urine occult blood. Bacteriuria and pyuria were detected in a urinesediment test. Urine was cultured on blood agar and Levine agar in a bacteriological incubator at 37°C under aerobiosis,for 24 h...
