Salmonellosis is a zoonotic disease, and spp. can sometimes be found in dogs and cats, posing a risk to human health. In this study, the prevalence and antimicrobial susceptibility of faecal were investigated in pet dogs and cats in Xuzhou, Jiangsu Province, China.
Faecal samples from 243 dogs and 113 cats, at seven pet clinics, were tested between March 2018 and May 2019. Each isolate was characterised using serotyping and antimicrobial susceptibility tests.
The prevalence of was 9.47% in dogs and 1.77% in cats. Among the 25 isolates, eight serotypes of subsp. were detected, . Kentucky (n = 11), . Indiana (n = 5), and . Typhimurium (n = 4) predominating. . Derby, . Toucra, . Sandiego, . Newport, and . Saintpaul all occurred singly. The 23 strains found in dogs were from seven different serovars, while the two strains in cats were from two. The highest resistance rates were found for tetracycline (92%), azithromycin (88%), cefazolin (84%), nalidixic acid (80%), ampicillin (80%), ceftriaxone (80%), and streptomycin (76%). Resistance to three or more antimicrobial agents was detected in 24 (96%) isolates. Most of the . Kentucky and . Indiana isolates were multi-drug resistant to more than 11 agents.
The carriage rate was far higher in dogs than in cats from Xuzhou. Some isolated strains were highly resistant to antimicrobials used to treat infections in humans and pets, which may raise the risk of humans being infected with multi-drug resistant via close contact with pets.
沙门氏菌病是一种人畜共患病，某些沙门氏菌有时可在犬猫体内发现，对人类健康构成风险。本研究对中国江苏省徐州市宠物犬猫粪便中沙门氏菌的流行情况及抗菌药物敏感性进行了调查。
2018年3月至2019年5月期间，在七家宠物诊所对243只犬和113只猫的粪便样本进行了检测。每个沙门氏菌分离株通过血清分型和抗菌药物敏感性试验进行鉴定。
犬的沙门氏菌携带率为9.47%，猫为1.77%。在25个分离株中，检测到8种肠炎沙门氏菌亚种血清型，以肯塔基血清型（n = 11）、印第安纳血清型（n = 5）和鼠伤寒血清型（n = 4）为主。德比血清型、图克拉血清型、圣地亚哥血清型、纽波特血清型和圣保罗血清型均为单个出现。犬体内发现的23株沙门氏菌来自7个不同血清型，而猫体内的2株来自2个血清型。四环素（92%）、阿奇霉素（88%）、头孢唑林（84%）、萘啶酸（80%）、氨苄西林（80%）、头孢曲松（80%）和链霉素（76%）的耐药率最高。24个（96%）分离株检测到对三种或更多抗菌药物耐药。大多数肯塔基血清型和印第安纳血清型分离株对11种以上药物多重耐药。
徐州犬的沙门氏菌携带率远高于猫。一些分离菌株对用于治疗人和宠物感染的抗菌药物高度耐药，这可能增加人类通过与宠物密切接触感染多重耐药沙门氏菌的风险。
