An infection of a young male roe deer caused by Erysipelothrix rhusiopathiae with a pronounced thrombotic endocarditis in the left valves and focal necrosis in the septum of the heart leading to bacterial sepsis is described. Findings of this kind are extremely rare in roe deer. However, they document the wide host range, which is also illustrated by the numerous publications on such infections in other species.

This report describes the first documented case of Erysipelothrix rhusiopathiae endocarditis in Latin America. The patient was a 51-years-old male, moderate alcoholic, with a previous history of aortic failure. He was used to fishing and cooking as a hobby and had his left hand wounded by a fish-bone. The disease began with erysipeloid form and developed to septicemia and endocarditis. He was treated with antibiotics and surgery for aortic valve replacement. There are only 46 cases of E. rhusiopathiae endocarditis reported to date. The authors wonder if several other cases might go unreported for lack of microbiological laboratorial diagnosis.

The clinical, pathomorphological and microbiological findings during meat inspection in 599 pigs with endocarditis at slaughter were studied. Clinical signs were observed in 41 per cent of the pigs on ante-mortem inspection. Lameness was the most common sign. However, this symptom is not very specific of endocarditis. This is also true of various other symptoms. Only dyspnoea and drowsiness were indicative of endocarditis to some extent, but occurred only sporadically. Extracardial lesions were observed in 66 per cent of the pigs with endocarditis on post-mortem inspection. Metastatic processes (infarction or inflammatory foci) were most frequently detected in the kidneys. These were highly specific of endocarditis. In addition, the following changes were observed in decreasing incidence: signs of sepsis (hyperplastic splenitis, petechiae and degradation of organs), inflammatory lesions of the joints and legs, metastatic pneumonia and inflammation of the tail. Bacteriological examination was positive in 62 per cent of the cases. Streptococci were the organisms most frequently isolated (36 per cent), followed by Corynebacterium pyogenes (19 per cent) and Erysipelothrix rhusiopathiae (14 per cent). The discussion is concerned with the significance of these bacteria to meat-consumers.

In inoculated pack experiments on Clostridium botulinum type E, unirradiated and 0.1-Mrad irradiated haddock fillets often gave nonspecific toxicities by the mouse assay test for botulinum toxin. Samples given 0.2-Mrad radiation failed to produce nonspecific reactions. Nonspecific deaths sometimes occurred within 24 hr after injection, although deaths between 24 and 48 hr were more common. The symptoms and the pattern of these deaths suggested a septicemia. Heart-blood cultured from mice showing nonspecific symptoms indicated an infectious process. Among 23 isolates from the blood, eight were identified as Proteus vulgaris, two P. morganii, one P. rettgeri, one Providence subgroup B, two Aerobacter aerogenes, one Actinobacillus, three enterococci, one Alcaligenes marshalli, and four Erysipelothrix insidiosa. The E. insidiosa, Aerobacter, Providence group, and most of the Proteus isolates were infectious for mice when injected by the intraperitoneal route. But the enterococci, Alcaligenes, and Actinobacillus isolates were not infectious and probably represent secondary invaders. The cultural characteristics of the E. insidiosa isolates conform to those described in the literature, with the exception that the four strains grew in the temperature range 50 F (10 C) to 40 F (4.4 C). Nonspecific toxicities were avoided in assays for botulinum toxin by the protection of mice with chloramphenicol and oxytetracycline.

The clinical features of endocarditis of the aortic valve in 24 dogs were reviewed. This condition was found most commonly in large-breed, middle-aged male dogs. Evidence of antecedent infection or immunosuppression was usually not historically verified or found at necropsy. However, an association with congenital heart disease, especially discrete subaortic stenosis, was demonstrated. The most frequent clinical findings were systolic and diastolic murmurs and bounding arterial pulses, with or without signs of congestive heart failure. The most commonly isolated organisms were Corynebacterium sp, Erysipelothrix rhusiopathiae, and Streptococcus sp. In addition to antibiotic therapy, treatment for congestive heart failure often was required. Despite aggressive therapy, most affected dogs died as a result of congestive heart failure, arrhythmias, infarction, sepsis, or renal failure.

Erysipelothrix infections have been a well-known clinical entity for over a century. Only a few cases have been studied histologically, and the agent has rarely been cultured from infected patients. We present here a case of erysipeloid of Rosenbach, in which histologic study and electron microscopy document the presence of microorganisms. We also present a complete review of the clinical and pathologic features of Erysipelothrix infections and their treatment. Our observations suggest that Erysipelothrix rhusiopathiae is capable of producing L forms that may revert to a bacterial form and produce sepsis at a later time.

Erysipelothrix rhusiopathiae septicemia was diagnosed in three of four moose found dead in Algonquin Provincial Park, Ontario, Canada, in the spring of 1989. Type 17 E. rhusiopathiae was isolated from liver, lung, kidney, and lymph nodes of affected animals, which were in poor body condition, and suffering hair loss associated with tick (Dermacentor albipictus) infestations. Microscopic lesions consisted of mild, multifocal, necrotizing myocarditis, sarcocystosis, and lymph node atrophy. The bacterium may have gained entry to these animals via ingestion of, or percutaneous exposure to, contaminated water, or possibly by the bites of ticks. Malnutrition and tick infestation may have predisposed the animals to infection by this opportunistic pathogen.

One male of a group of seven Pacific white-sided dolphins (Lagenorhynchus obliquidens) died after a brief period of nonspecific clinical signs. Four beluga whales (Delphinapterus leucas) and four harbor seals (Phoca vitulina) were managed in the same water system. Gross examination of the dolphin revealed only moderately enlarged mesenteric lymph nodes. Histopathology revealed small to massive numbers of gram-positive bacilli, usually intravascular, in all tissues. Bacteria were both extracellular and present in macrophages, monocytes, and neutrophils. Aerobic bacterial culture of lung, liver, kidney, and spleen yielded pure cultures of Erysipelothrix rhusiopathiae. Based on clinical course, histopathology, and bacteriology, a diagnosis of acute erysipelas septicemia was made. None of the other cetaceans or pinnipeds exhibited clinical signs.

Erysipelothrix rhusiopathiae is a causal agent of swine erysipelas, which is of economic importance in the swine industry by virtue of causing acute septicemia, chronic arthritis, and endocarditis. However, little is known about the genetic properties of its protective antigens. Recently, a surface protective antigen (SpaA) gene was identified from serotype 2 in a mouse model. We cloned spaA from virulent strain Fujisawa (serotype 1a) and determined that the N-terminal 342 amino acids without C-terminal repeats of 20 amino acids have the ability to elicit protection in mice. Fusions of 342 amino acids of Fujisawa SpaA and histidine hexamer (HisSpa1.0) protected pigs against challenge with both serotype 1 and serotype 2, the most important serotypes in the swine industry. Pigs immunized with HisSpa1.0 reacted well with both HisSpa1.0 and intact SpaA by enzyme-linked immunosorbent assay and immunoblotting. Serum collected at the time of challenge from a pig immunized with HisSpa1. 0 markedly enhanced the in vitro phagocytic and killing activity of pig neutrophils against the bacteria. DNA sequences of protective regions of spaA genes from five strains of serotypes 1 and 2 were almost identical. The full DNA sequences also seemed to be conserved among strains of all 12 serotype reference strains harboring the spaA gene by restriction fragment length polymorphism analysis of PCR products. These results indicates that SpaA is a common protective antigen of serotypes 1 and 2 of E. rhusiopathiae in swine and will be a useful tool for development of new types of vaccines and diagnostic tools for effective control of the disease.

A flock of 810 pheasants experienced 6.2% mortality over 6 days. Affected birds were weak and lethargic for up to 24 hr before death. Examined birds were thin, and gross lesions consisted of thick opaque crops and cecal cores. Histologically, there was capillariasis of the crop and multifocal ulcerative typhlitis with Heterakis spp. infection, and numerous systemic intravascular monocytes were filled with clusters of blue rod-shaped organisms. The organisms were gram-positive bacilli by Brown and Brenn staining and ultrastructural analysis. Liver bacterial cultures were negative for pathogenic bacteria. Erysipelas septicemia was diagnosed by an Erysipelothrix species-specific polymerase chain reaction method with the substrate DNA isolated from formalin-fixed, paraffin-embedded liver.
