Molecular Insights into the Genetic Variability of ORF Virus in a Mediterranean Region (Sardinia, Italy).

Life (Basel) 2021 May 4;11(5). Epub 2021 May 4.

Istituto Zooprofilattico Sperimentale della Sardegna, 07100 Sassari, Italy.

Orf virus (ORFV) represents the causative agent of contagious ecthyma, clinically characterized by mild papular and pustular to severe proliferative lesions, mainly occurring in sheep and goats. In order to provide hints on the evolutionary history of this virus, we carried out a study aimed to assess the genetic variation of ORFV in Sardinia that hosts a large affected small ruminant population. We also found a high worldwide mutational viral evolutionary rate, which resulted, in turn, higher than the rate we detected for the strains isolated in Sardinia. Read More

Contagious ecthyma: how serious is the disease worldwide?

Anim Health Res Rev 2021 May 21:1-16. Epub 2021 May 21.

Virology Laboratory, Department of Pathology and Microbiology, Faculty of Veterinary Medicine, University Putra Malaysia, Malaysia, 43400 Serdang, Selangor, Malaysia.

Contagious ecthyma (CE) is an infectious disease of small ruminants caused by a parapoxvirus of family Poxviridae subfamily Chordopoxvirinae. The disease is obviously distinguished by an establishment of scabby lesions and ulcerative formation on less hairy areas including muzzle, ears, nostril, and sometimes on genitalia. The disease is endemic in sheep and goats. Read More

The genetic identification of camel contagious ecthyma virus as the causative agent of contagious ecthyma in dromedary camels (Camelus dromedarius) in Qatar.

Trop Anim Health Prod 2021 May 18;53(2):332. Epub 2021 May 18.

Camel Genetic Research Center, Tharb Camel Hospital, Leawaina, Qatar.

Camel contagious ecthyma is a contagious viral disease of camels caused by either Orf virus (ORFV) or camel contagious ecthyma virus (CCEV). It has been previously reported and shown to cause economic losses in some camel-rearing countries in Asia and Africa, but has not been detected in Qatar.

Acute myeloid leukaemia presenting with ecthyma gangrenosum as the first manifestation: A case report.

Medicine (Baltimore) 2021 May;100(18):e25867

Department of Emergency Medicine, St. Mary's Hospital, Kurume, Japan.

Rationale: Ecthyma gangrenosum (EG) is an uncommon cutaneous infection usually associated with Pseudomonas aeruginosa bacteremia in immunocompromised patients, particularly those with underlying malignant diseases. Despite its rarity, especially in immunocompetent or nondiagnosed immunodeficiency patients, EG can present as the first manifestation of an underlying immunosuppression.

Patient Concerns: A 42-year-old Japanese man was admitted to our hospital with a 3-day history of a painless red macule on his right forearm and fever. Read More

Division of Pediatric Immunology Diseases, Dr. Sami Ulus Maternity and Children's Training and Research Hospital, Ankara, Turkey.

septicemia is rare in previously healthy children. Skin lesions such as subcutaneous nodules and ecthyma gangrenosum may be the first manifestation of infection that have rarely been reported. Herein we reported a previously healthy 6-month-old boy patient who presented with suppurative otitis media, multiple nodules, septic shock, and was identified in cultures of the blood, skin lesions, and purulent material of his ears.

Roraima, 1000, Santa Maria, Rio Grande do Sul, 97105-900, Brazil. Electronic address:

The parapoxvirus orf virus (ORFV) encodes several immunomodulatory proteins (IMPs) that modulate host innate and pro-inflammatory responses to infection. Using the ORFV IA82 strain as the parental virus, recombinant viruses with individual deletions in the genes encoding the IMPs chemokine binding protein (CBP; ORFV112), inhibitor of granulocyte-monocyte colony-stimulating factor and IL-2 (GIF, ORFV117) and interleukin 10 homologue (vIL-10; ORFV127) were generated and characterized in vitro and in vivo. The replication properties of the individual gene deletion viruses in cell culture was not affected comparing with the parental virus. Read More

An Eschar-like souvenir from a journey to Colombia: Ecthyma gangrenosum as a differential diagnosis of tropical diseases in immunocompromised patients - a case report.

BMC Infect Dis 2021 Apr 12;21(1):344. Epub 2021 Apr 12.

German Center for Infection Research (DZIF), partner site Munich, Munich, Germany.

Background: Ecthyma gangrenosum (EG) is a cutaneous infectious disease characterized by eschar-like skin ulcers typically caused by Pseudomonas aeruginosa. Here, we report a case of relapsing EG in a patient who had returned from a trip to Colombia, thus establishing EG as an important differential diagnosis of tropical diseases, and demonstrating that even long-term antibiotic treatment can result in only partial remission of EG.

Case Presentation: A 77-year-old man with underlying chronic lymphocytic leukemia (CLL) on ibrutinib treatment was admitted because of a superinfected mosquito bite on the left ear and multiple partially necrotic skin lesions disseminated all over the entire body five days after returning from a trip to Colombia.

Department of Ecosystem and Public Health, Faculty of Veterinary Medicine, University of Calgary, 3280 Hospital Dr. NW, Calgary, Alberta, Canada T2N 4Z6.

A wild muskox (Ovibos moschatus) with dermatitis typical of contagious ecthyma had secondary bacterial septicemia with Corynebacterium freneyi that included laminitis, hepatitis, and suppurative encephalitis. This case supports the association between orf virus infection and fatal secondary infections, which may have contributed to population declines on Victoria Island, Canada. Read More

Ecthyma gangrenosum: The critical role of biofilms and other mechanisms of antibiotic resistance and implications for management.

Pediatr Dermatol 2021 Mar 2;38(2):458-460. Epub 2021 Jan 2.

Division of Dermatology, Children's National Hospital, Washington, DC, USA.

Ecthyma gangrenosum is a rare cutaneous infection that occurs classically in immunocompromised patients with Pseudomonas aeruginosa bacteremia and is associated with a high mortality rate. Causative pathogens may exhibit various antibiotic evasion mechanisms, and thus, treatment may be challenging. We present a case of ecthyma gangrenosum in association with an implantable port in which cultures confirmed ten unique strains of Pseudomonas aeruginosa, highlighting the ability of this pathogen to form biofilms, rapidly mutate and ultimately evade antibiotic therapy.

College of Medicine, King Saud University, Riyadh, Saudi Arabia.

BACKGROUND Orf, also known as ecthyma contagiosum, is a zoonotic disease caused by a parapox virus, which is endemic in goats and sheep but rare in camels. Orf is usually transmitted to humans who are in contact with infected animals. The clinical manifestation of the disease and a personal history of contact with an infected animal are sufficient to diagnose orf virus infection. Read More

Clinical and Histopathologic Characteristics of the Main Causes of Vascular Occlusion - Part I: Thrombi.

Actas Dermosifiliogr (Engl Ed) 2021 Jan 9;112(1):1-13. Epub 2020 Oct 9.

Servicio de Anatomía Patológica, Hospital Universitario de Cruces, Barakaldo, Vizcaya, España.

Vascular occlusion has multiple, diverse clinical manifestations, some of which can have grave consequences for patients. The causes of vascular occlusion are also highly variable, ranging from thrombi triggered by the uncontrolled activation of coagulation mechanisms, on the one hand, to endothelial dysfunction or occlusion by material extrinsic to the coagulation system on the other. In a 2-part review, we look at the main causes of vascular occlusion and the key clinical and histopathologic findings. Read More
