HiE.coli0157TM Latex Test Kit

• is a rapid latex agglutination test intended for confirmatory identification of E. coli serogroup 0157 cultured on selective solid media.

• The test allows the rapid differentiation of E. coli 0157 from other E. coli serotypes and organisms isolated samples.

• This kit contains latex particles coated with antibodies raised against the liposaccharide 0157 antigen of E. coli 0157:H7.

Nosocomial

• any disease contracted by a patient while under medical care

• The bacteria can also be transmitted from person-to-person in families and in child care and other institutional care centers.

Hemolytic uremic syndrome (HUS)

a serious complication that can lead to kidney failure and death

• Severe bloody diarrhea

• Non-bloody diarrhea

• Little to no fever

• Fatigue

• Nausea

• Hemolytic uremic syndrome (HUS)

symptoms of an E. coli infection

• Fluids to prevent dehydration (diarrhea)

• Anti-diarrheal medication

• Antibiotics (most people get better without using antibiotics).

• Consult medical assistants from health care providers for better treatment.
