Erythema contusiforme, when a subcutaneous hemorrhage (bleeding under the skin) occurs with an erythema nodosum lesion, causing the lesion to look like a contusion (bruise) Erythema nodosum migrans (also known as subacute nodular migratory panniculitis ), a rare form of chronic erythema nodosum characterized by asymmetrical nodules that are ...
The nodules have diameters that measure approximately 1–5 cm. Erythema nodosum is due to inflammation of the underlying subcutaneous tissue (panniculitis), and biopsy will display focal panniculitis (although is often unnecessary in diagnosis). In contrast to joint-related manifestations, erythema nodosum often occurs alongside intestinal ...
Other stool tests involve the detection of antibiotic resistance as to guide appropriate therapy, e.g. Clarithromycin resistance of Helicobacter pylori represents a major challenge in eradication therapy but the responsible bacterial genomic markers can be detected in stool using PCR technology and thus can guide the prescription of the ...
Diagnosis is by stool culture or testing for the bacteria's DNA or toxins. [1] If a person tests positive but has no symptoms, the condition is known as C. difficile colonization rather than an infection. [1] Prevention efforts include terminal room cleaning in hospitals, limiting antibiotic use, and handwashing campaigns in hospitals. [2]
Yersinia enterocolitica is a Gram-negative, rod-shaped bacterium, belonging to the family Yersiniaceae.It is motile at temperatures of 22–29°C (72–84°F), but becomes nonmotile at normal human body temperature.
Yersiniosis is an infectious disease of the gastrointestinal tract caused by bacteria of the genus Yersinia other than Y. pestis. Most cases of yersiniosis in humans are caused by Y. enterocolitica, with a small minority being caused by Y. pseudotuberculosis. Rarely, other species of the genus can cause yersiniosis. [1]
In severely ill people with IBD there is a risk of the passage of viable bacteria from the gastrointestinal tract to the internal organs (bacterial translocation) and subsequent bacteremia, which can cause serious adverse health consequences. [135]
Erythema (Ancient Greek: ἐρύθημα, from Greek erythros 'red') is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. [1] It occurs with any skin injury, infection, or inflammation. Examples of erythema not associated with pathology include nervous blushes. [2]
