The prevalence of Salmonella spp. was determined in 970 animals comprising 423 pet birds, 485 fish aquaria water and 62 other pets (40 pet mammals, 14 reptiles, eight others - crustaceans, snail, stingray) from both pet shops and households throughout Trinidad. The serotypes of Salmonella spp. isolated were identified and the resistance to various antimicrobial agents was determined. Overall nine (0.9%) of 970 pet animals were positive for Salmonella spp. Six isolates of Salmonella spp. were recovered from all pet birds with two isolates of serotype Aberdeen and one isolate each of Thompson, Rubislaw, Panama and Newport. The prevalence of Salmonella spp. in birds was 0.9%. Four isolates of Salmonella spp. were recovered from fish aquaria water, serotypes included Panama (two isolates), Newport (one isolate) and Virchow (one isolate). Prevalence of Salmonella spp. from fish aquaria was 0.4%. No isolate of Salmonella spp. was detected in pet mammals sampled while two isolates were recovered from reptiles, S. Enteritidis and S. Montevideo. One isolate of Salmonella spp. was recovered from a stingray, serotype unknown. Antimicrobial resistance was present is all animal types. The highest prevalence of resistance was to streptomycin among isolates from birds (83.3%) and other pets (100.0%) while isolates from fish aquarium water exhibited comparatively high resistance to cephalothin (50.0%). It was concluded that the isolation of Salmonella spp. from apparently healthy birds, fish aquarium water and other pet animals may pose a health risk to their owners and contacts as all serotypes are known to be potentially pathogenic depending on the oral dosage of the organism and the immune status of those in contact. The high prevalence of resistance to antimicrobial agents among Salmonella isolates across pet species may pose chemotherapeutic consequences to their owners and contacts.
在特立尼达岛各地的宠物店和家庭中，对970只动物进行了沙门氏菌属感染情况的检测，这些动物包括423只宠物鸟、485个鱼缸中的水以及62只其他宠物（40只宠物哺乳动物、14只爬行动物、8只其他动物——甲壳类动物、蜗牛、黄貂鱼）。对分离出的沙门氏菌属血清型进行了鉴定，并测定了其对各种抗菌剂的耐药性。总体而言，970只宠物动物中有9只（0.9%）沙门氏菌属检测呈阳性。从所有宠物鸟中分离出6株沙门氏菌属，其中2株为阿伯丁血清型，汤普森、鲁比斯劳、巴拿马和纽波特血清型各1株。鸟类中沙门氏菌属的感染率为0.9%。从鱼缸水中分离出4株沙门氏菌属，血清型包括巴拿马（2株）、纽波特（1株）和威尔肖（1株）。鱼缸水中沙门氏菌属的感染率为0.4%。在采样的宠物哺乳动物中未检测到沙门氏菌属分离株，而从爬行动物中分离出2株，分别为肠炎沙门氏菌和蒙得维的亚沙门氏菌。从一条黄貂鱼中分离出1株沙门氏菌属，血清型未知。所有动物类型均存在抗菌耐药性。鸟类分离株和其他宠物分离株中对链霉素的耐药率最高（分别为83.3%和100.0%），而鱼缸水分离株对头孢噻吩的耐药性相对较高（50.0%）。研究得出结论，从看似健康的鸟类、鱼缸水和其他宠物动物中分离出沙门氏菌属可能会对其主人和接触者构成健康风险，因为众所周知，所有血清型根据生物体的口服剂量和接触者的免疫状态都可能具有潜在致病性。宠物物种中沙门氏菌分离株对抗菌剂的高耐药率可能会给其主人和接触者带来化疗方面的影响。
