Infectious agents associated with fetal and early neonatal death and abortion in swine.
Laboratory examination of specimens from 824 porcine abortions over a 6-year period produced 320 (38.8%) diagnoses. Viruses were involved in 22% and bacteria in 16.5% of all cases. Enterovirus was the virus isolated most often (10.9%), followed by parvovirus (4.9%), reovirus (4.4%), pseudorabies virus (1%), and adenovirus (0.8%). Leptospirosis was the bacterial infection most commonly diagnosed (9.8%), with numerous miscellaneous bacterial and fungal infections making up the remainder (7.0%) of the infectious causes.
