The virus is endemic in sheep and goats worldwide and manifests as an acute contagious skin conditio...

This technique has also been used extensively in studies on the structure of pox viruses. Horne & Wildy (1963) have reviewed the results obtained by various investigators working with this group of viruses. The more recently published findings of Buttner, Giese, Muller & Peters (1964) and Peters, Muller & Buttner (1964) suggest that the viruses of the pox group can be divided into the following...

Poxviruses continue to pose a major threat to human health. Monkeypox is endemic in central Africa, and the discontinuation of the vaccination (with vaccinia virus) has rendered most humans vulnerable to variola virus, the etiologic agent of smallpox, should this virus be used in biological warfare or terrorism. However, a large variety of compounds have been described that are potent inhibitor...

This cutaneous infection is characterized by a crusted papule or plaque beneath which a deep ulcer forms. Although typically associated with group A b-hemolytic streptococci, other pathogens have the ability to produce an ecthyma. Here we present a case of ...
