What is the route of infection for C. diff?

difficile infection has been increasing worldwide to become one of the most common hospital-acquired infections. Transmission of this pathogen occurs by the fecal-oral route and the most important risk factors include antibiotic therapy, old age, and hospital or nursing home stay.

What is the difference between Clostridium difficile infection CDI and C. difficile colonization?

diff is more common than infection. Colonized patients do not have disease caused by C. diff and often exhibit NO clinical symptoms (asymptomatic) of infection (e.g., diarrhea); colonized patients do test positive for the C. diff organism or its toxin.

Is C diff infection life threatening?

Clostridioides difficile (klos-TRID-e-oi-deez dif-uh-SEEL) is a bacterium that causes an infection of the large intestine (colon). Symptoms can range from diarrhea to life-threatening damage to the colon. The bacterium is often referred to as C. difficile or C.

What are the virulence factors of Clostridium difficile?

The main virulence factors of C. difficile are two toxins, toxin A (TcdA) and toxin B (TcdB).

How did I get C. diff?

You are more likely to get a C. diff infection if you take antibiotics for more than a week. C. diff spreads when people touch food, surfaces, or objects that are contaminated with feces (poop) from a person who has C.

How long do you stay colonized with C. diff?

Someone who is colonized has NO signs or symptoms. Colonization is more common than C. diff infection and does not require treatment. Once your body is colonized, you can remain colonized for several months.

What does it mean to have colonized C. diff?

We define “C. difficile colonization” as the detection of the organism in the absence of CDI symptoms and “C. difficile infection” as the presence of C. difficile toxin (ideally) or a toxigenic strain type and clinical manifestations of CDI (Fig. 1).

What is the survival rate of C. diff?

Moreover, the 5-year survival rate for the long-term survival group was poor, at 38% (16.3% for all patients). Twenty percent of patients had restored gastrointestinal continuity. One case of recurrence of C difficile colitis was reported.

Is C. diff genetic?

A 3.6 year study involving WGS of isolates from more than 1200 patients with CDI reported that only 35% of C. difficile cases were genetically related (Eyre et al., 2013); another study of adult patients performed in the United Kingdom reported that 19% were genetically related (Mawer et al., 2017).

How do the toxins of C. difficile contribute to the signs of disease?

C. difficile causes disease by producing the toxins TcdA and TcdB that function to disrupt protein synthesis within the host cell. The toxins are responsible for producing symptoms such as watery diarrhea, fever, loss of appetite, nausea, and severe abdominal pain [1].

How contagious is C. diff to a healthy person?

difficile infection from touching infected people or surfaces and not washing their hands. Even if people have no symptoms of C. diff infection, they can still spread the infection to others. However, most healthy adults will not get sick from contact with C.

What is the survival rate for C. diff?

Should C. diff Colonization be treated?

Colonization and Infection difficile is more common than C. difficile infection (CDI) and in most cases, should not be treated. CDI is present when a patient tests positive for toxigenic C. difficile bacteria and clinical symptoms of infection are present.

How long can someone be colonized with C. diff?

Colonization is more common than C. diff infection and does not require treatment. Once your body is colonized, you can remain colonized for several months.
