Erisipela suína: relato de caso no município de Cachoeiras de Macacu-RJ / Swine erysipelas: case report in the city of Cachoeiras de Macacu-RJ

Na suinocultura perdas econômicas ainda são elevadas devido aos baixos padrões de qualidade e sanidade dos animais. Dentre as afecções que afetam a produção, a erisipela é uma doença considerada importante em função dos prejuízos econômicos que causa, e pela questão de saúde pública visto ser uma zoonose. Ela é uma enfermidade do tipo hemorrágica comumente causada pela bactéria ubíqua Erysipelotrix rhusiopathiae. O objetivo deste trabalho foi relatar um caso desta afecção em uma matriz da raça Large White, de dois anos de idade, recém desmamada, não vacinada, de uma pequena granja de ciclo completo no munícipio de Cachoeiras de Macacu, estado do Rio de Janeiro. Ela amanheceu prostrada, com dificuldade de locomoção, sem febre e com manchas avermelhadas sobre toda a superfície corporal. As lesões cutâneas, ligeiramente elevadas, apresentavam um formato losangular (diamante) característico e sugestivo de Erisipela. Após a identificação do problema, o animal foi isolado e tratado. O tratamento iniciou-se na manhã do mesmo dia, observando-se a regressão da maioria das lesões à tarde e na manhã seguinte. A suspeita clínica foi confirmada através do diagnóstico terapêutico, sendo a associação de penicilina e estreptomicina eficiente no tratamento.

In swine industry, economic losses are still high due to low standards of quality and health of animals. Among the diseases that affect production, erysipelas is a disease considered important due to the economic losses it causes, and because of the public health issue as it is a zoonosis. It is a hemorrhagic type disease commonly caused by the ubiquitous bacteria Erysipelotrix rhusiopathiae. The aim of this study was to report a case of this condition in a Large White breed sow, two years old, recently weaned, not vaccinated, from a small pig farm (farrow to finish operation) in the municipality of Cachoeiras de Macacu, state of Rio de Janeiro. The sow was prostrate and with limited mobility, without fever and with reddish spots on the entire body surface. The cutaneous lesions were elevated, with a characteristic diamond shape suggestive of erysipelas. After identifying the problem, the animal was isolated and treated. The treatment started in the morning of the same day, observing the regression of most lesions in the afternoon and the following morning. The clinical diagnosis was confirmed through therapeutic diagnosis, and the association of penicillin and streptomycin was efficient in the treatment.

Approach to Aquatic Skin Infections.

Aquatic-based infections can present a treatment challenge for primary care physicians because of the likely polymicrobial nature of the infection and the possibility of uncommon pathogenic organisms. Although Staphylococcus and Streptococcus species that colonize the skin are the most common etiologic agents associated with saltwater and freshwater skin and soft tissue infections, other significant pathogens can include Vibrio, Aeromonas, Edwardsiella, Erysipelothrix, and Mycobacterium. Early detection and appropriate management of aquatic infections can significantly decrease morbidity and mortality. This article reviews the pathophysiology, presentation, and management for the most common water-borne pathogens causing skin and soft tissue infections.

A child with Erysipelothrix arthritis-beware of the little known.

Erysipelothrix rhusiopathiae is an established animal pathogen while the zoonotic infections in humans are rarely reported. Infections occur after exposure to animals or animal products that are mostly occupational in adults. Here we report in a child for the first time septic arthritis and osteomyelitis without an identifiable risk factor. A 5-year-old male child was admitted with pain in the left hip joint and inability to bear weight on the limb. Clinical examination followed by radiological and magnetic resonance imaging was suggestive of septic arthritis. Erysipelothrix rhusiopathiae grew from peroperative joint specimen. The infection was resolved following arthrotomy, joint lavage and antibiotic therapy.

Aquatic sports dermatoses: Part 3. On the water.

The third of this three-part series on water-related sports dermatoses discusses skin changes seen in athletes who participate in sporting activities on top of or nearby water. While also susceptible to several of the freshwater and saltwater dermatoses discussed in parts one and two of the series, these athletes may present with skin changes unique to their particular sports. This updated and comprehensive review details those near-water dermatologic conditions commonly seen in sailors, rowers, fishermen, surfers, windsurfers, rafters, and water skiers, and will serve as a guide for dermatologists, sports medicine physicians and other medical practitioners in recognition and treatment of these conditions.

Management of extremity trauma and related infections occurring in the aquatic environment.

Wounds sustained in oceans, lakes, and streams are exposed to a milieu of bacteria rarely encountered in typical land-based injuries. These include Vibrio species, Aeromonas hydrophila, Pseudomonas and Plesiomonas species, Erysipelothrix rhusiopathiae, Mycobacterium marinum, and other microbes. Failure to recognize and treat these less common pathogens in a timely manner may result in significant morbidity or death. Initial antibiotic therapy should address common gram-positive and gram-negative aquatic bacteria, depending on the environment. Trauma occurring in brackish or salt water should be treated with doxycycline and ceftazidime, or a fluoroquinolone (eg, ciprofloxacin or levofloxacin). Freshwater wounds should be managed with ciprofloxacin, levofloxacin, or a third- or fourth-generation cephalosporin (eg, ceftazidime). Injuries sustained in a marine or freshwater environment may result from bites or venomous stings of aquatic organisms as well as from accidental trauma. Musculoskeletal trauma caused by venomous underwater species (eg, stingrays, stinging fish, sea urchins, and coral) requires immediate neutralization of the heat-labile toxin with immersion in nonscalding water for 30 to 90 minutes. Appropriate management of aquatic wounds requires recognition of the mechanism of injury, neutralization of venom, antibiotic administration, radiographic assessment, surgical débridement with irrigation, wound cultures, and structural repair or amputation as indicated by the severity of the injury.

[Infective endocarditis caused by Erysipelothrix rhusiopathiae--case report]. / Infekcyjne zapalenie wsierdzia wywolane paleczka rózycy.

Infective endocarditis (IE) is an infectious disease, which leads to death when is untreated. In most cases IE is caused by typical bacteria. IE caused by atypical bacteria is rare. In this paper, we describe a female patient with IE caused by Erysipelothrix rhusiopathiae (ER). Due to inflammation and leaflets' damage she underwent double-valve implantation (aortic and mitral ones). A long-term antibiotic therapy was given with good outcome. We also describe the organism, types of human diseases caused by ER and treatment options.

Necrotizing fasciitis caused by Erysipelothrix rhusiopathiae.

A woman with diabetes mellitus type 2 had a thigh infection that drained foul-smelling pus. Necrotizing fasciitis was diagnosed surgically and histopathologically, with Erysipelothrix rhusiopathiae being the predominant organism. A pet goldfish might have been the source.

Erysipelothrix rhusiopathiae endocarditis: a preventable zoonosis?

BACKGROUND: Erysipelothrix rhusiopathiae is a bacterium ubiquitous in the environment. It can cause a variety of diseases and the risk of infection is closely related to the level of occupational exposure to infected or colonised animals. AIMS: To discuss the clinical features and treatment of this zoonosis, to increase awareness of this pathogen and to emphasise the need for meticulous attention to hygienic work practices in reducing the risk of infection. METHOD: A case report of a farmer with E. rhusiopathiae endocarditis and the management of the infection. RESULTS: The patient was successfully treated with valve replacement surgery and antimicrobial therapy. CONCLUSIONS: Early identification of this microorganism is essential for appropriate treatment of endocarditis. Greater awareness and safe work practices can help reduce the risk of human infection by this microorganism.

Erysipelothrix rhusiopathiae septic arthritis.

We describe herein the case of a man with Erysipelothrix rhusiopathiae septic arthritis and possible infective endocarditis. This is the first report in the English-language medical literature of septic arthritis caused by this organism.

Erysipelothrix rhusiopathiae: bacteriology, epidemiology and clinical manifestations of an occupational pathogen.

Erysipelothrix rhusiopathiae has been recognised as a cause of infection in animals and man since the late 1880s. It is the aetiological agent of swine erysipelas, and also causes economically important diseases in turkeys, chickens, ducks and emus, and other farmed animals such as sheep. The organism has the ability to persist for long periods in the environment and survive in marine locations. Infection in man is occupationally related, occurring principally as a result of contact with animals, their products or wastes. Human infection can take one of three forms: a mild cutaneous infection known as erysipeloid, a diffuse cutaneous form and a serious although rare systemic complication with septicaemia and endocarditis. While it has been suggested that the incidence of human infection could be declining because of technological advances in animal industries, infection still occurs in specific environments. Furthermore, infection by the organism may be under-diagnosed because of the resemblance it bears to other infections and the problems that may be encountered in isolation and identification. Diagnosis of erysipeloid can be difficult if not recognised clinically, as culture is lengthy and the organism resides deep in the skin. There have been recent advances in molecular approaches to diagnosis and in understanding of Erysipelothrix taxonomy and pathogenesis. Two PCR assays have been described for the diagnosis of swine erysipelas, one of which has been applied successfully to human samples. Treatment by oral and intramuscular penicillin is effective. However, containment and control procedures are far more effective ways to reduce infection in both man and animals.

Treatment and control by vaccination of erysipelas in farmed emus (Dromaius novohollandiae).

OBJECTIVE: To study erysipelas in farmed emus and the treatment and control of the disease by vaccination. DESIGN: A retrospective study of field outbreaks in emus and challenge experiments in mice using field and vaccine strains of the organism. PROCEDURE: Outbreaks of the disease were described. Field strains of the organism were identified and tested by challenge experiments in mice against commercial vaccine strains. RESULTS: Erysipelas was characterised by sudden death in yearling emus. Deaths mainly occurred during the cold wet months. Mortalities of 6 to 10% were seen within the first 7 to 10 days of an outbreak. Clinical signs were uncommon but some birds exhibited lethargy and greenish diarrhoea. Necropsy findings included marked petechial haemorrhages on the serosal surface of the large intestine in particular, pericardial effusion and congestion and mottling of the liver. Treatment consisted of individual or mass medication with procaine penicillin, reduction of stress factors such as overcrowding, and spelling and rotation of paddocks. Isolates from two field outbreaks were identified as strain 21. Complete protection was provided by a commercial strain 2b vaccine against challenge by strain 21 field isolates in mice. Annual vaccination of birds at 4 weeks and again at 8 weeks of age appeared to control further outbreaks on farms where the disease had previously occurred and vaccination appeared to protect for at least 12 months.

Erysipelothrix rhusiopathiae endocarditis: clinical features of an occupational disease.

Erysipelothrix rhusiopathiae is becoming more commonly recognized in humans and has the potential for significant morbidity and mortality. In this article, we describe one patient's clinical symptoms after occupational exposure to E rhusiopathiae and its sequela. We discuss the natural history of the organism, three major categories of human disease, and treatment options.

[Endocarditis from Erysipelothrix rhusiopathiae]. / Endokarditis durch Erysipelothrix rhusiopathiae.

Erysipelothrix rhusiopathiae only seldom causes cases of endocarditis. Contact with infectious animals leads to endocarditis of the left heart with high lethality. Vancomycin and aminoglycosides, which are often used in gram-positive endocarditis, show no effect.
