Evaluation of Udder Preparations on Intramammary Infections
Journal of Dairy Science, 1988 Udder preparations of wet towel plus drying and .1% iodophor premilking teat dipping plus drying were compared with no preparation to determine effects on number of new intramammary infections. Teats of 84 cows were challenged (5 d/wk) for 18 wk with a culture broth of Streptococcus uberis 3 h prior to each p.m.

Intramammary Infections in Primigravid Heifers Near Parturition
Journal of Dairy Science, 1983 Mammary secretion from 32 primigravid heifers was obtained aseptically to determine frequency of bacterial isolation and incidence of intramammary infection near parturition. Quarter samples were collected 14 and 7 days prior to expected parturition, at parturition, and 7 and 14 days postparturition.

Serratia Species Isolated from Bovine Intramammary Infections
Journal of Dairy Science, 1991 Intramammary infections from which Serratia spp. were isolated were studied over a 32-mo period in a research dairy herd consisting of approximately 120 lactating cows. A total of 29 Serratia spp. intramammary infections were detected and accounted for 9% of all Gram-negative bacterial intramammary infections.
