ISOLATION FROM HOWLER () AND SPIDER MONKEYS () AT A ZOOLOGIC FACILITY IN CENTRAL ILLINOIS.

was initially isolated from an asymptomatic black howler monkey () in a routine fecal culture examination. Fecal cultures from other individuals in this group and an adjacently housed black-headed spider monkey () group recovered from all but one of the individuals sampled (1.1 spider monkeys and 2.1 howler monkeys). Concurrently, one spider monkey presented with acute onset severe rectal prolapse and diarrhea. Whole-genome sequencing results of isolates from all individuals were homologous and closely related to subsp. TTU_618, a strain typically associated with environmental samples. In addition, two cytolethal distending toxin (CDT) expressing gene clusters, -I and II, were identified in all isolates. These results suggest is transmissible to both howler monkeys and spider monkeys, though the origin of infection and whether it is transmissible between these species is undetermined.
