Salmonellosis is a bacterial infection caused by Salmonella spp. When it affects the gastrointestinal tract of cats, it has a predilection for the ileocecocolic junction. Abdominal ultrasound is a valuable tool in diagnosing gastrointestinal diseases. This retrospective, single-center case series study aimed to describe the ultrasonographic abnormalities of the ileocecocolic junction in feline patients with confirmed Salmonella infection. One hundred cats presenting with gastrointestinal symptoms were tested for Salmonella between 2019 and 2022; 70 tested positive, and 30 tested negative. All of them underwent ultrasonographic examination. The positive group showed a significantly thickened wall of the ileum ( < 0.001, range: 1.9-5.7 mm, mean = 3.25 mm, SD = 0.66), caecum ( < 0.001, range: 2.1-3.9 mm, mean = 2.87 mm, SD = 0.49), and ascending colon ( < 0.05, range: 1-3.1 mm, mean = 1.47 mm, SD = 0.55) in comparison to the negative group. In the positive group, the ileocecal lymph nodes were significantly larger in diameter ( < 0.001, range: 2.7-7.8 mm, mean = 4.9 mm, SD = 1.15). All Salmonella-positive cats had focal hyperechoic mesenteric fat, and 23% (16/70) had focal peritoneal effusion at the ileocecocolic junction. The combination of the thickening of the intestinal wall at the ileocecocolic junction, focal hyperechoic mesenteric fat, peritoneal effusion and regional lymphadenopathy may indicate Salmonellosis in cats with compatible clinical signs. Including this diagnosis may prompt further testing, leading to early recognition and effective treatment, resulting in better patient outcomes. Diagnosing this disease is also important as Salmonellosis carries a zoonotic risk, with the potential transmission between pets and humans.
沙门氏菌病是由沙门氏菌属引起的细菌感染。当它影响猫的胃肠道时，易发生于回盲结肠交界处。腹部超声是诊断胃肠道疾病的一种有价值的工具。这项回顾性、单中心病例系列研究旨在描述确诊为沙门氏菌感染的猫科动物患者回盲结肠交界处的超声异常。2019年至2022年间，对100只出现胃肠道症状的猫进行了沙门氏菌检测；70只检测呈阳性，30只检测呈阴性。所有猫都接受了超声检查。与阴性组相比，阳性组的回肠壁（<0.001，范围：1.9 - 5.7毫米，平均 = 3.25毫米，标准差 = 0.66）、盲肠壁（<0.001，范围：2.1 - 3.9毫米，平均 = 2.87毫米，标准差 = 0.49）和升结肠壁（<0.05，范围：1 - 3.1毫米，平均 = 1.47毫米，标准差 = 0.55）明显增厚。在阳性组中，回盲部淋巴结直径明显更大（<0.001，范围：2.7 - 7.8毫米，平均 = 4.9毫米，标准差 = 1.15）。所有沙门氏菌阳性的猫都有局灶性高回声肠系膜脂肪，23%（16/70）在回盲结肠交界处有局灶性腹腔积液。回盲结肠交界处肠壁增厚、局灶性高回声肠系膜脂肪、腹腔积液和局部淋巴结病的组合可能提示有 compatible临床症状的猫患有沙门氏菌病。纳入这一诊断可能会促使进一步检测，从而实现早期识别和有效治疗，使患者获得更好的预后。诊断这种疾病也很重要，因为沙门氏菌病存在人畜共患病风险，有可能在宠物和人类之间传播。
