Cat-scratch disease (CSD) is an infectious disease that most often results from a scratch or bite of a cat. [4] Symptoms typically include a non-painful bump or blister at the site of injury and painful and swollen lymph nodes. [2] People may feel tired, have a headache, or a fever. [2] Symptoms typically begin within 3–14 days following ...
Pustule: A pustule is a small elevation of the skin usually consisting of necrotic inflammatory cells. [30] Cyst: A cyst is an epithelial-lined cavity. [10] Wheal: A wheal is a rounded or flat-topped, pale red papule or plaque that is characteristically evanescent, disappearing within 24 to 48 hours.
Kittens in particular are more likely to be infected with and pass along CSD, and are also considered more likely to scratch and bite a human while playing compared to an older cat.
The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3] Within the latter type, the hairs occur in structures called pilosebaceous units , each with hair follicle , sebaceous gland , and associated arrector pili muscle. [ 4 ]
Bartonella henselae, formerly Rochalimæa henselae, is a bacterium that is the causative agent of cat-scratch disease [1] (bartonellosis). Bartonella henselae is a member of the genus Bartonella, one of the most common types of bacteria in the world. [specify] It is a facultative intracellular microbe that targets red blood cells.
Superficial pustular folliculitis is a superficial folliculitis with thin-walled pustules at the follicular openings. [2]: 252 ...
The roof of the pustule is parakeratotic stratum corneum, and the floor is formed of keratinocytes, which may or may not be acantholytic. [6] Neutrophils begin to fill the pustule. Toxins are produced by S. aureus and target desmoglein, which is a desmosomal cell-cell adhesion molecule found in the upper levels of the epidermis.
Erythrasma manifests mostly in slightly webbed spaces between toes (or other body region skin folds like the thighs/groin area) in warm atmospheric regions, and is more prevalent in dark skinned humans. As a person ages, they are more susceptible to this infection.
