Human Erysipelothrix rhusiopathiae infection via bath water - case report and genome announcement.

Erysipelothrix rhusiopathiae is a facultative anaerobic, environmentally stable, Gram-positive rod that causes swine and avian erysipelas as a zoonotic pathogen. In humans, the main manifestations described are circumscribed erysipeloid, generalized erysipeloid, and endocarditis. Here, we report a 46-year-old female patient who presented to the physician because of redness and marked functio laesa of the hand, in terms of a pain-related restricted range of motion, and was treated surgically. E. rhusopathiae was detected in tissue biopsy. The source of infection was considered to be a pond in which both swine and, later, her dog bathed. The genome of the isolate was completely sequenced and especially the presumptive virulence associated factors as well as the presumptive antimicrobial resistance genes, in particular a predicted homologue to the multiple sugar metabolism regulator (MsmR), several predicted two-component signal transduction systems, three predicted hemolysins, two predicted neuraminidases, three predicted hyaluronate lyases, the surface protective antigen SpaA, a subset of predicted enzymes that potentially confer resistance to reactive oxygen species (ROS), several predicted phospholipases that could play a role in the escape from phagolysosomes into host cell cytoplasm as well as a predicted vancomycin resistance locus (vex23-vncRS) and three predicted MATE efflux transporters were investigated in more detail.

Erysipeloid cutaneous leishmaniasis: a study of 40 cases of an unusual variant.

BACKGROUND: Erysipeloid cutaneous leishmaniasis (ECL) is known as the chronic form of cutaneous leishmaniasis (CL). However, keeping its clinical presentation in view, there is a need to revisit this form of the disease. AIMS: To describe ECL in view of clinical features and treatment modalities. METHODS: We include a case series seen in Sfax (Southern Tunisia) from January 2017 to January 2021. All patients clinically suggestive and laboratory confirmed with a diagnosis of CL were registered. Patients of all age groups and of either gender having cutaneous lesions resembling erysipela on the face were included in the study. Different demographic features of the patients and clinical aspects were identified. Descriptive statistics were used for analysis. RESULTS: Of 1300 registered patients with CL, 40 (3%) were diagnosed as ECL. Ages ranged from 15 to 65 years, and duration of lesions varied from 15 to 180 days. All patients had lesions over the face. Clinically, a painful infiltrated inflammatory placard of the central facial area with a butterfly shape was observed in 14 cases, as well as zones of the cheekbone (11 cases), cheekbone and nose (5 cases), cheekbone and eyelid (8 cases), and cheekbone with ear (2 cases). Several therapeutic methods were prescribed with a sufficient result with no recurrence. CONCLUSION: ECL is a rare presentation that typically occurs on the face, looking like erysipelas, in patients who are native from an endemic region of CL.

Case Report: Erysipeloid Cutaneous Leishmaniasis Treated with Oral Miltefosine.

Cutaneous leishmaniasis (CL) can present with various skin lesions ranging from a single ulcer to diffuse multiple nodules. Here, we present a case of a 67-year-old man with a large erythematous well-defined indurated plaque over the left face for a duration of 4 months. A slit skin smear was performed, and it was stained with Giemsa stain which showed multiple amastigotes confirming the diagnosis of CL. Oral miltefosine was started at a dose of 150 mg/day but had to be stopped after 20 days as the patient developed diarrhea, bipedal edema, and renal impairment. This case emphasizes an uncommon variant of CL and the role of systemic treatment with oral miltefosine and its associated adverse effects.

Erysipeloid lesions caused by Erysipelothrix rhusiopathiae in a dog: clinical and histopathological findings, molecular diagnosis and treatment.

BACKGROUND: Erysipelothrix rhusiopathiae is a widespread Gram-positive, nonsporulating rod bacterium predominantly associated with skin disease in swine and cetaceans. Cutaneous lesions have yet to be described in dogs. OBJECTIVE: To describe the clinical presentation, molecular and histopathological diagnosis, and treatment of a case of erysipeloid caused by E. rhusiopathiae in a dog. ANIMALS: A 6-month-old spayed female standard poodle dog presented with lethargy, fever, vomiting and diarrhoea. Skin lesions appeared 20 days post first examination. METHODS AND MATERIALS: Complete blood count, serum chemistry profile, urinalysis, urine culture, blood culture, computed topography, forelimb radiography, joint and cerebrospinal fluid aspiration were performed; samples were collected for skin cytological evaluation, culture and histopathological analysis. RESULTS: Blood cultures yielded Gram-positive, catalase-negative bacilli. Histopathological evaluation of skin biopsies revealed lymphoplasmacytic, neutrophilic and histiocytic perivascular and periadnexal dermatitis, and vasculitis. Cutaneous and blood PCR and sequencing of 16S rRNA identified the bacteria as E. rhusiopathiae. Clinical resolution was observed following the use of of amoxicillin/clavulanic acid and ciprofloxacin therapies. CONCLUSIONS AND CLINICAL IMPORTANCE: To the best of the authors' knowledge, this is the first confirmed case of erysipeloid caused by E. rhusiopathiae in a dog. Clinical resolution was attained with the extended use of antibiotics. After 13 months, no clinical signs had returned.

Erysipelatoid Carcinoma.

Erysipelatoid Carcinoma (EC), also known as Inflammatory Metastatic Carcinoma, is a rare form of cutaneous metastasis, secondary to an internal malignancy, more often related to breast cancer. Clinically, the lesion has a well-marked, bound erythematous appearance, much like an infectious process, such as erysipelas and cellulitis, these being the most common differential diagnoses. It is characterized by an acute or subacute appearance with an erythematous plaque, sometimes hot and painful, being more often situated in the primary tumor vicinity, especially in the thorax wall in the region of a mastectomy due to breast cancer. Here we present the case of a 75-year-old patient with ductal infiltrated carcinoma for 3 years, who presented an acute erythematous and infiltrated plaque in the region of a previous mastectomy, with a final diagnosis of EC.

Erysipelothrix rhusiopathiae recruits host plasminogen via the major protective antigen SpaA.

Erysipelothrix rhusiopathiae is the causative agent of animal erysipelas and human erysipeloid. Some pathogenic bacteria are able to recruit host plasminogen and then use the plasminogen system for migration across tissue barriers or for nutritional demands during infection. However, there is no study on E. rhusiopathiae recruitment of plasminogen. SpaA has long been known to be a major protective antigen of E. rhusiopathiae, but its roles in virulence have not yet been well clarified. The aim of this study was to detect the activity of E. rhusiopathiae to recruit host plasminogen and evaluate the ability of SpaA to act as a receptor in the recruitment process. It was found that E. rhusiopathiae could recruit host plasminogen. SpaA could specifically bind host plasminogen. Anti-SpaA serum could significantly decrease the activity of E. rhusiopathiae to recruit plasminogen. In addition, this binding activity was lysine dependent. In conclusion, E. rhusiopathiae was able to recruit host plasminogen via SpaA. To our knowledge, this is the first report on E. rhusiopathiae recruitment of host plasminogen and the receptor in the process.

Erysipeloid rash: A rare adverse event induced by gemcitabine.

Some rare cases of erysipelas-like or pseudocellulitis have been reported in relation to gemcitabine. This rare adverse event is more frequent in the presence of edema. Here, we report a case of pseudocellulitis after adjuvant treatment for pancreatic cancer. Oncologists should be aware of this infrequent and non-well understood adverse event. They should be especially careful when administering gemcitabine in the presence of lymphedema.

No abstract available.

A case of apparent canine erysipeloid associated with Erysipelothrix rhusiopathiae bacteraemia.

BACKGROUND: Erysipelothrix rhusiopathiae is a Gram-positive facultative anaerobe found worldwide and is most commonly associated with skin disease in swine, while anecdotal reports of cases in dogs have been associated with endocarditis. HYPOTHESIS/OBJECTIVES: Clinicians should consider systemic infectious diseases as a potential cause of erythematous skin lesions. ANIMALS: A 5-year-old female spayed Labrador retriever presented with lethargy, anorexia and erythematous skin lesions while receiving immunosuppressive therapy for immune-mediated haemolytic anaemia. Four days prior to presentation, the dog had chewed on a raw turkey carcase. METHODS: Complete blood count, serum chemistry profile, urinalysis and blood cultures. RESULTS: Blood cultures yielded a pure growth of E. rhusiopathiae serotype 1b. Amoxicillin 22 mg/kg orally twice daily for 2 weeks and discontinuation of azathioprine resulted in remission of fever and skin lesions. CONCLUSIONS AND CLINICAL IMPORTANCE: This report is the first documentation, to the best of the authors' knowledge, of Erysipelothrix infection, a known zoonosis, in an immunosuppressed dog, highlighting the need for infectious disease monitoring in patients receiving such therapy. This information may also help educate veterinarians to include Erysipelothrix infection as a differential diagnosis in dogs with fever and skin lesions, as well as the role of blood cultures in diagnosing this disease.

Empyema in spinal canal in thoracic region, abscesses in paravertebral space, spondylitis: in clinical course of zoonosis Erysipelothrix rhusiopathiae.

OBJECTIVES: Erysipelas is an animal disease caused by Gram-positive bacteria Erysipelothrix rhusiopathiae. Among the domestic animals, domestic pig (Sus scrofa f. domestica) suffers most frequently from the disease in human environment. This is a typical animal-borne disease observed mainly in occupational groups employed in agriculture, farming (of animals and birds), fishing and manufacturing industry. METHODS: We are presenting the clinical course of infection (E. rhusiopathiae) and discuss clinical forms. E. rhusiopathiae in humans may have the following clinical course: mild form of skin infection diagnosed as local erythema (erysipeloid), disseminated form of skin infection and the most serious form of infection of systemic course (endocarditis and sepsis). Mild skin infection and local erythema are the most common forms. Very rare case of animal-borne infection course has been presented in which after initial phase the disease was generalised to the abscesses formation in paravertebral space, spondylitis and empyema formation in spinal canal. In the presented clinical case, the patient was suffering from diabetes. It was probably an additional risk factor of the disease generalisation. Patient underwent drainage of empyema in spinal canal, after which his neurological status gradually improved. Antibiotic therapy was implemented and continued for 8 weeks. Such course of erysipelas was not previously described in the literature. RESULTS: After therapy neurological status was improved. In follow MRI control exam empyema and spondylitis was successfully eliminated. CONCLUSIONS: Various complications of the disease, such as endocarditis and heart valves disturbances, are well known and are the most severe complications of the generalised infection. Proper targeted and long-term antibiotic therapy is crucial.
