We describe a case of erysipelas in a free-ranging endangered Hawaiian crow. The partially scavenged carcass exhibited gross emaciation and petechial hemorrhages in both lungs. Microscopy revealed multiple necrotic foci associated with gram-positive rods in the liver and adrenal, diffuse acute proximal tubular necrosis of kidney, diffuse necrosis and inflammation of proventricular mucosa associated with gram-positive rods, and multiple intravascular aggregates of gram-positive rods associated with thrombi. Culture of the kidney revealed the bacterium to be Erysipelothrix rhusiopathiae. The implications of this finding to free-ranging crows remain unclear.

The pathogenicity of 79 Erysipelothrix isolates from bovine tonsils for mice and swine was determined. Five (6.3%) isolates were lethal for mice. These isolates belonged to serovars 1b (one isolate), 2 (2), 19 (1) and 21 (1). The 50% lethal dose values of the isolates ranged from 0.33 to 5x10(2) CFUs in mice. Twenty Erysipelothrix isolates (25.3%) were weakly virulent inducing only emaciation while 12 (15.2%) inducing emaciation and ruffled hair. In swine, clinical signs of varying severity were observed. Four isolates were virulent, capable of inducing localized or generalized urticarial lesions accompanied with a rise in body temperature after intradermal inoculation. One isolate each of serovars 1b, 2 and 19 was highly virulent, capable of inducing generalized urticarial lesions while another Erysipelothrix isolate of serovar 2 induced only a localized urticarial lesion at the site of inoculation. Another isolate of serovar 1b induced itching and irritation without obvious urticarial lesion at the site of inoculation. On the other hand, one isolate of serovar 21 and two other isolates of serovar 2 could not induce experimentally any clinical sign of erysipelas other than rise in body temperature. There was a rise in growth agglutination (GA) titer of serum in all the inoculated swine. These observations suggest that Erysipelothrix isolates from cattle are pathogenic for mouse and swine, and may also be pathogenic for other animals and humans.

Erysipelothrix rhusiopathiae is pathogenic for humans, many domestic animals and wild birds, but infectious cases with clinical symptoms in cats have not been reported. E. rhusiopathiae was recovered from a 4-month Russian blue breed cat with a very poor body condition score of 1 (BCS: 1/5). The isolate was typed as serotype 2b. Mice experimentally infected with the clinical isolate of E. rhusiopathiae through subcutaneous or intraperitoneal routes survived, and the organism was recovered from the spleen and synovial and pericardial fluids. Cats experimentally inoculated with the isolate either orally or subcutaneously survived but commonly exhibited depression and emaciation together with localized erythemal lesion of the skin accompanied by purulent ocular discharge. On hematological analysis, the number of total white blood cells was high compared with that in normal cats. Histological examination revealed congestion and moderate inflammation with focal necrosis. This observation may provide insight on E. rhusiopathiae infection in cats with the possible epidemiological significance and implications as a potential source of infection to other animals and humans.

A previously unrecognized condition is described in wild free-ranging Pribilof arctic foxes ( Alopex lagopus pribilofensis) from the Pribilof Islands, Alaska, USA. This condition is called shaggy lame fox syndrome (SLFS) denoting the primary clinical signs first observed. Criteria used to suspect SLFS on gross examination included emaciation, failure to shed winter pelage and moderate to severe polyarthritis. Criteria used to confirm SLFS histologically included polyarthritis (characterized by lymphoplasmacytic synovitis, tenosynovitis, bursitis, periosteal bony proliferation, and periarticular lymphoplasmacytic vasculitis) and systemic leukocytoclastic vasculitis. Other histological lesions often found included renal cortical infarcts, myocarditis with myocardial infarcts, lymphoplasmacytic meningitis, lymphoplasmacytic cuffing of meningeal and a few cerebral vessels, and cavitating infarcts of the brainstem and thalamus. The cause of SLFS is not known at this time; however, the gross and histological lesions suggest that the cause of SLFS may be a bacterial polyarthritis with a secondary immune-mediated vasculitis. These lesions are consistent with changes described with Erysipelothrix rhusiopathiae in domestic dogs; E. rhusiopathiae was identified from the synovial membrane of a swollen stifle joint and the kidney from one fox using real-time polymerase chain reaction and with culture from a fox that had gross and histological lesions of SLFS. Therefore, E. rhusiopathiae is a possible etiological agent for SLFS.
