Verocytotoxin-producing Escherichia coli, Japan, 1999–2004
In 1999, an infectious disease prevention law was enacted in Japan that affected the nationwide infectious surveillance system. A total of 19,304 laboratory-confirmed verocytotoxin-producing Escherichia coli cases were reported through 2004. The annual incidence was 2.74/100,000 population; its fluctuation over time and space was associated with climate, socioeconomic, and population factors.
متن کاملShiga Toxin/Verocytotoxin-Producing Escherichia coli Infections: Practical Clinical Perspectives.
Escherichia coli strains that produce Shiga toxins/verotoxins are rare, but important, causes of human disease. They are responsible for a spectrum of illnesses that range from the asymptomatic to the life-threatening hemolytic-uremic syndrome; diseases caused by E. coli belonging to serotype O157:H7 are exceptionally severe. Each illness has a fairly predictable trajectory, and good clinical p...
متن کاملRapid biochemical test to identify verocytotoxin-positive strains of Escherichia coli serotype O157.
Fluorogenic procedures were used with the substrate 4-methylumbelliferyl-beta-D-glucuronide (MUG) to identify Escherichia coli. Most strains produced beta-glucuronidase and, thus, were MUG positive. A 20-min procedure was developed to detect glucuronidase activity in 1,295 bacterial cultures, representing 23 genera, of strains that were isolated from clinical specimens. Very few organisms other...
متن کامل[Epidemiological importance of humans and domestic animals as reservoirs of verocytotoxin-producing Escherichia coli].
BACKGROUND/AIM A "new" pathogenic agent, verocytotoxin--producing Escherichia coli (VTEC) emerged in the last 20 years, causing an increased number of sporadic cases, as well as of outbreaks of diarrhoeal diseases. Humans and animals can be infected with VTEC, but their epidemiological importance as a reservoir of this agent is not quite clear, especially in the Balkan region. Therefore, the ai...
متن کاملIsolation and characterization of verocytotoxin-producing Escherichia coli O157 strains from Dutch cattle and sheep.
In the periods from July to November 1995 and 1996, fecal samples from Dutch cattle and sheep were collected at the main slaughterhouses of The Netherlands, located at different geographic sites. The samples were examined for the presence of verocytotoxin (VT)-producing Escherichia coli (VTEC) of serogroup 0157. E. coli O157 strains could be isolated from 57 (10.6%) of 540 adult cattle, 2 (0.5%...
