Abstract

Umbilical structures infections can be followed by bacteremic, septicemic infections and death in newborns with passive immunity deficiency. Microorganisms isolated in omphalitis have been also isolated from animals with bacteremia. From september/2002 to september/2003, a research was developed using 44 calves, in order to evaluate bacteremia frequency in newborns and to correlate microorganisms isolated from blood samples and umbilical structures. Blood samples were collected from jugular vein for microorganisms isolation. Twenty four samples were collected in a period of 24 to 48 hours, the other 20 samples from thirty to fifty days after birth. Umbilical structures materials were collected though swabs. Microbial growth occurred in 17 (38,67%) blood samples and in 100% of umbilical samples. Staphylococcus spp., E. coli, Bacillus spp, Pseudomonas spp. and Streptococcus spp were the major isolated microorganisms from blood. All bacteremic animals presented systemic or localized clinical manifestations. The most reported clinical sign was thickness of umbilical structures. Bacillus spp, Enterobacter spp, Micrococcus spp. and E. coli were isolated from umbilical structures. Data confirm a mixed bacterial environment in omphalitis, and suggest a high prevalence of bacteremic infections in newborns calves, pointing out the need of passive immunity transfer through colostrum.
