BACKGROUND Orf virus, the prototype of parapoxvirus, is the main causative agent of contagious ecthyma. Little is known about the status of the disease in Ethiopia and this study was aimed at determining its status using PCR as a confirmatory tool. METHODS a total of 400 randomly selected sheep and goat was screened for the identification of the virus using amplification of B2L gene and trans...

On the basis of observational and experimental evidence, several authors have proposed that contagious yawn is linked to our capacity for empathy, thus presenting a powerful tool to explore the root of empathy in animal evolution. The evidence for the occurrence of contagious yawning and its link to empathy, however, is meagre outside primates and only recently domestic dogs have demonstrated t...

Parapoxvirus infection in sheep and goats is usually referred to as contagious pustular dermatitis/ecthyma, or orf, and the corresponding human infection is referred to as orf. In humans, after a brief incubation period of 3 to 5 days, lesions begin as pruritic erythematous macules and then rise to form papules, often with a target appearance. Lesions become nodular or vesicular, and orf lesion...

Five persons in France were infected with Orf virus after skin wounds were exposed to infected sheep tissues during Eid al-Adha, the Muslim Feast of Sacrifice. Infections were confirmed by electron microscopy, PCR, and sequence analysis. Prevention and control of this underdiagnosed disease can be achieved by educating physicians, slaughterhouse workers, and persons participating in Eid al-Adha.

Spirochetes of the genus Treponema were cultured from 7 of 10 cases of digital dermatitis in sheep. Two cultures comprised Treponema phagedenis-like and Treponema medium/Treponema vincentii-like spirochetes, respectively, while the remaining cultures comprised mixed populations of Treponema medium/Treponema vincentii-like, Treponema phagedenis-like, and Treponema denticola/Treponema putidum-lik...

Norscia et al. [1] recently reported the first evidence for a sex bias in contagious yawning among humans. Based on previous research showing an indirect connection between contagious yawning and empathy (e.g. [2–4], but see [5,6]) and that levels of empathy appear to be higher in women compared with men (e.g. [7–9]), the authors investigated whether there is also a sex difference in the expres...

We report the first outbreak of nosocomial orf infection in a hospital burn unit in Gaziantep, Turkey. The outbreak lasted from October to December 2012 and involved a total of thirteen cases. It demonstrates the risk of introduction of orf virus to a burn unit, and the potential for extensive transmission among patients with compromised skin integrity. The importance of hygiene measures and in...
