Most occur in the first 10d pp. Check cows on a daily basis in the first 10 days to make sure they do not have infection. Keep an eye on them until day 21. Multifactorial = depends on pathogens and host factors: host factor: immunocompetence, pathogen factors: load and pathogenicity. Fimh (e coli) and fima (t pyogenes) are adhesive proteins. )are exotoxins = create lesions of the epithelium of endometrium. Heavy load of pathogens in maternity pens. Rp moves inside and out as the animal moves = more bacterial exposure. May lead to rp because chorionic villi not mature. Have to put hand inside uterus may introduce pathogens.
