Decorrente do surto de leptospirose que aconteceu no Centro de Recolha Oficial de Animais de Santarém (CROAS), entre os meses de abril e julho do ano de 2024, realizou-se um estudo de caso que teve como objetivo caraterizar a população de canídeos infetados com Leptospira spp, assim como identificar possíveis fatores de risco que possam ter contribuído para a ocorrência deste surto e alertar para o impacto que esta doença pode ter a nível da saúde pública em contexto de medicina de abrigo. Os cães do CROAS foram diagnosticados a partir de imunofluorescência para deteção de IgG e/ou IgM, sendo que foram diagnosticados 22 cães com leptospirose, dos quais 18 (81,8%) eram machos e 4 (18,2%) fêmeas. Não foi realizado nenhum outro exame complementar de diagnóstico. Os sinais clínicos mais frequentes foram hematoquézia (40,9%) e fezes com muco (40,9%). Apenas os animais positivos no teste foram sujeitos a tratamento antimicrobiano com doxiciclina, com uma taxa de sucesso terapêutico de 95,5%. Dos quatro funcionários presentes no CROAS nesse período, dois contraíram a doença (50%), sendo que um precisou de internamento prolongado devido à gravidade do quadro clínico. Identificou-se como fator de risco os cães estarem alojados nas boxes interiores ao invés das exteriores, pátio e cercados (p=0,043; OR=3,47). Sugerindo uma maior probabilidade de contacto com poças de água ou escorrências contaminadas com urina de cães infetados ou urina de roedores, portadores assintomáticos, ou ambas. Este estudo de caso revela a importância da adoção de rigorosas medidas de biossegurança interna e externa em Medicina de Abrigo, na prevenção de zoonoses num contexto de “Uma Saúde”
ABSTRACT - Case study of the leptospirosis outbreak at the Official Animal Collection Center of Santarém - Resulting from the leptospirosis outbreak that occurred at the Official Animal Collection Center of Santarém (CROAS), between April and July 2024, a case study was conducted with the aim of characterizing the canine population infected with Leptospira spp., as well as identifying possible risk factors that may have contributed to the outbreak and raising awareness of the impact this disease can have on public health in a shelter medicine context. Dogs at CROAS were diagnosed using immunofluorescence to detect IgG and/or IgM, and 22 dogs were diagnosed with leptospirosis, of which 18 (81.8%) were males and 4 (18.2%) females. No other complementary diagnostic tests were performed. The most frequent clinical signs were hematochezia (40.9%) and mucus in the stool (40.9%). Only animals testing positive were subjected to antimicrobial treatment with doxycycline, with a therapeutic success rate of 95.5%. Of the four employees present at CROAS during this period, two contracted the disease (50%), with one requiring prolonged hospitalization due to the severity of his clinical condition. A risk factor was identified: dogs housed in indoor kennels instead of outdoor areas, patios, and enclosures (p=0.043; OR=3.47). Suggesting a higher probability of contact with puddles or runoff contaminated with urine from infected dogs or urine from rodents, asymptomatic carriers, or both. This case study reveals the importance of adopting strict internal and external biosafety measures in Shelter Medicine, in the prevention of zoonoses in a “One Health” context
