In humans, Erysipelothrix rhusiopathiae infections most commonly present in a mild cutaneous form known as erysipeloid  or fish poisoning. E. rhusiopathiae can cause an indolent cellulitis, more commonly in individuals who handle fish and raw meat. Erysipelothrix rhusiopathiae also causes Swine Erysipelas. It is common in domestic pigs and can be transmitted to humans who work with swine. It gains entry typically by abrasions in the hand. Bacteremia and endocarditis are uncommon but serious sequelae. Due to the rarity of reported human cases, E. rhusiopathiae infections are frequently misidentified at presentation. Diagnosis
Violaceous swelling with severe pain but without pus (Which differentiates from pus forming streptococcal and staphylococcal erysipelas)

Erysipeloid of Rosenbach
Erysipeloid of Rosenbach is a cutaneous condition most frequently characterized by a purplish marginated swelling on the hands. : 264  The eponym Rosenbachs disease is in reference to the milder type of the condition and is named after Friedrich Julius Rosenbach. Early work on the condition in US fishermen was carried out by Klaunders and colleagues. Treatment
The treatment of choice is a single dose of benzathine benzylpenicillin given by intramuscular injection, or a five-day to one-week course of either oral penicillin or intramuscular procaine benzylpenicillin. Erythromycin or doxycycline may be given instead to people who are allergic to penicillin. E. rhusiopathiae is intrinsically resistant to vancomycin. See also

Herpesviral meningitis is meningitis associated with herpes simplex virus (HSV).HSV-2 is the most common cause of Mollarets meningitis, a type of recurrent viral meningitis. This condition was first described in 1944 by French neurologist Pierre Mollaret. Recurrences usually last a few days or a few weeks, and resolve without treatment. They may recur weekly or monthly for approximately 5 years following primary infection. Diagnosis
Although DNA analysis techniques such as polymerase chain reaction can be used to look for DNA of herpesviruses in spinal fluid or blood, the results may be negative, even in cases where other definitive symptoms exist. Treatment
