The diagnosis of erysipelas is usually made clinically. Features that help distinguish erysipelas are acute onset, erythema, warmth, edema, pain, fever, and isolated regional involvement with clearly demarcated margins. High ASO titers and response to penicillin therapy are reassuring. Simple uncomplicated erysipelas or cellulitis in adults can usually be treated on an outpatient basis. Extensive facial involvement with fever and a toxic appearance warrants hospitalization. Facial cellulitis or erysipelas in children, unless quite limited, requires hospitalization because of the high risk of Hemophilus influenzae infection and sepsis. Hospitalized patients should show visible signs of resolution and be afebrile for at least 24 hours prior to discharge. They should be maintained on oral antibiotic therapy at home for an additional 7 to 10 days.

Seven methods of serotyping of Haemophilus influenzae were evaluated. Comparing slide agglutination, staphylococcal coagglutination, latex agglutination, counterimmunoelectrophoresis, immunofluorescence, capsular swelling, and cultivation on antiserum agar the commercial coagglutination test was most reliable, most rapid, and easiest to perform. To identify all six serotypes this coagglutination test had to be combined with slide agglutination. With most methods best results were achieved by using cultures incubated at 37 degrees C for 6 h. As nonencapsulated strains often agglutinated unspecifically, selection of probably typeable strains was useful. Differentiation with help of colonial morphology and opalescent growth was facilitated by cultivation on Brain Heart Infusion (BHI) Chocolate Agar and testing of growth factor requirements on translucent BHI Agar with strips containing the growth factors V, X, and VX, respectively. In broth turbid growth was a hint for encapsulation. Nigrosin staining, a negative capsule staining, proved to be useful if specific antisera are not available. From 252 clinical isolates of H. influenzae 216 were not typeable. 36 strains could be serotyped. 27 (75%) belonged to serotype b, 6 (16.6%) were serotype e, 3 (8.3%) were serotype f. Serotype e and f were most difficult to identify. Spectrum of patients and diseases were corresponding to the findings of other authors. Less well-known infections like cellulitis (erysipelas of the cheeks) and arthritis were observed, too. Rapid identification of at least H. influenzae type b could render treatment in some cases more effective by early application of a suitable antibiotic.

The potent immunomodifier Propionibacterium avidum KP-40 (PA) demonstrated prophylactic potency in swine infected experimentally with Haemophilus (Actinobacillus) pleuropneumoniae or Erysipelothrix rhusiopathiae. Animals received PA either together with the respective vaccine or PA only; 3 resp. 4 weeks later all animals were inoculated with virulent pathogens. Eight of 10 swine immunized with inactivated pleuropneumonia vaccine developed mild-moderate forms of infection with temporary stagnation of body weight; application of the vaccine together with PA lowered the morbidity rate to 1 of 10 (p < 0.05). Also in non-vaccinated swine infected with pleuropneumonia or erysipelas PA application resulted in milder clinical symptoms, faster recovery and a larger gain of body weight.

Diagnosis of erysipelas is based upon the association of an acute inflammatory plaque with fever, lymphagiitis, adenopathy and hyperleukocytosis. These associated symptoms are variable (20-70 p. 100 of cases). Bacteriology is not helpful for the diagnosis of erysipelas because of a low sensitivity (hemoculture 5 p. 100, standard examinations 5-41 p. 100), or delayed positivity (serology). Moreover cutaneous bacteriology is difficult to assess when other bacteria than streptococci are isolated. Erysipelas have to be distinguished from non-necrotizing cellulitis by peculiar clinical features (such as erysipeloid, facial staphylococcal infection, Pasteurella, Haemophilus influenzae) and from necrotizing fasciitis. Some non-infectious diseases may mimic erysipelas such as venous thrombosis, familial Mediterranean fever, prosthesis intolerance, and compartment syndrome. Because the diagnostic value of clinical symptoms is not known and no diagnostic gold standard has been established, it is impossible to be sure that non-streptococcal erysipelas (especially staphylococcal) really exists. Thus, the first line treatment for all erysipelas must be an antistreptococcal antibiotic. Before prescribing a treatment, hemoculture and blood cell count could be useful. If antistreptococcal antibiotherapy is inefficient, all the differential diagnoses must be reviewed.
