Outbreak of K99+ Escherichia coli Infection and Serological Survey in Calves

Outbreak of K99+ Escherichia coli Infection and Serological Survey in Calves

The isolation of K99 Escherichia coli (K99 E. coli) was performed using diarrheal stool which occurred in calves from january through October, 1988. Moreover, bacteriolgical examination of isolated K99 E. coli and the adherent condition of K99 antigen in the intestinal canal of a dead calf was observed. In addition an epidemiological survey mainly including antibody examination of adult cattle ...

Experimental Infection of Calves with Escherichia coli O104:H4 outbreak strain

In 2011, a severe outbreak of hemolytic-uremic syndrome was caused by an unusual, highly virulent enterohemorrhagic E. coli (EHEC) O104:H4 strain, which possessed EHEC virulence traits in the genetic background of human-adapted enteroaggregative E. coli. To determine magnitude of fecal shedding and site of colonization of EHEC O104:H4 in a livestock host, 30 (ten/strain) weaned calves were inoc...

Case Report of Meningoencephalitis in Calves Caused by Escherichia coli

Experimental infection of calves with Escherichia coli O157:H7.

Three 3-month-old Japanese Black calves were experimentally infected with Escherichia coli O157:H7 to define the magnitude (CFU/g) and duration of fecal shedding of the organism. In two of the three calves, fecal shedding of E. coli O157:H7 ceased in 5 and 9 weeks. The remaining calf continued shedding E. coli O157:H7 for more than 31 weeks, and the magnitude of the shedding ranged from 10(1) t...

Factory outbreak of Escherichia coli O157:H7 infection in Japan.

To determine the cause of a July 1996 outbreak of Escherichia coli O157:H7 among factory workers in Kyoto, Japan, we conducted cohort and case-control studies. Eating radish sprout salad during lunch at the factory cafeteria had been linked to illness. The sprouts were traced to four growers in Japan; one had been associated with an outbreak of E. coli O157:H7 among 6,000 schoolchildren in Saka...
