亚利桑那沙门氏菌亚群含有革兰氏阴性肠道细菌，与其他沙门氏菌在生化、血清学和遗传学上密切相关。虽然亚利桑那亚群可能是从各种各样的非人类和人类来源中分离出来的，但亚利桑那亚群很少被认为是人类病原体，令人惊讶的是，对它们的流行病学知之甚少。从1967年到1976年，疾病控制中心收到了858个亚利桑那州亚群培养物，来自人类和非人类来源，代表33个体细胞组的143种不同血清型；有几种血清型以前未见报道。来自人类的374个培养物代表71种不同的血清型；31种（44%）血清型存在肠外分离株。与前20年的监测数据相比，从粪便、血液和其他部位分离的亚利桑那亚群菌株的比例非常稳定，但几种血清型在分离频率上表现出明显的变化。总体而言，肠外分离株与肠道分离株的比例为0.37，但存在明显的血清型特异性差异，表明毒力差异与血清型相关。
The Salmonella Arizona subgroup contains gram-negative enteric bacteria that are closely related to other salmonellae biochemically, serologically, and genetically. Although the Arizona subgroup may be isolated from a wide variety of nonhuman and human sources, the arizonae are uncommonly recognized as human pathogens, and suprisingly little is known about their epidemiology. From 1967 through 1976, the Centers for Disease Control received 858 Arizona subgroup cultures from human and nonhuman sources representing 143 different serotypes in 33 somatic groups; several serotypes had not been previously reported. The 374 cultures from humans represent 71 different serotypes; extraintestinal isolates were present in 31 (44%) serotypes. Compared with data from a previous 20 years of surveillance, the proportion of Arizona subgroup strains isolated from stools, blood, and other sites was remarkably stable, but several serotypes showed marked changes in their frequency of isolation. In total, the ratio of extraintestinal to intestinal isolates was 0.37, but marked serotype-specific variation was noted, suggesting differences in virulence associated with serotype.
