An account is given of the close correlations that exist between virus strains of bovine papular stomatitis, orf, pseudocowpox, and milker's nodule. Reference is made to literature data on natural infection of man with the above virus strains. A report then is presented on experimental infection of human volunteers, using paravaccine birus. While fairly tough and elevated nodules, 4 mm to 5 mm in diameter, were produced on the probends' skin, no re-isolation of virus was achieved.

The DNAs of eight parapoxviruses (four stomatitis papulosa viruses isolated from infected calves, a pseudocowpox virus isolated from a teat lesion of an infected cow and three orf viruses, one isolated from an infected sheep and two isolated from human infections) were analysed in CsCl gradients. The mole % of G+C was calculated from the buoyant density and found to be approx. 63% for all virus isolates examined. Parapoxvirus DNA thus has by far the highest G+C content of all poxvirus DNAs so far examined.

In accordance with the system of viral species, viral disorders of the oral mucosa may be classified with regard to their intensity of affection. There are but few viral infections exclusively affecting the oral mucosa like e.g. 1. Glossitis papulosa of Michelson, representing a special form of vaccinia inoculata, 2. Gingivo-stomatitis herpetica and 3. warts of the mucosa or condyloma-like papillomas of the oral mucosa including oral papillomatosis, that, itself shows morphological and clinical similarities to laryngeal papilloma. A second group of disorders mainly affecting the oral mucosa includes the "Aphthoid of Pospischill and Feyrter", Zahorsky's herpangina and other viral infections by the Coxsackie group, like vesicular stomatitis. The 3rd group represents viral infections of other organs in which affection of the oral mucosa is a prerogative, e.g. smallpox, varicella, foot-and-mouth disease and pharyngo-conjunctival fever. A 4th group includes those viral infections of the organs in which co-affection of oral mucosa occurs frequently or once in a while (at occasions). Here, we find eczema vaccinatum, herpes zoster, herpes simplex of the oral mucosa mostly on the hard palate, eczema herpeticatum, post-herpetic Erythema exsudativum multiforme, Mononucleosis infectiosa Pfeiffer, viral flu, German measles, parotitis epidemica, rubeola and ECHO-exanthema. A 5th and last group is made up by viral infections of other organs, in which affection of the oral mucosa hardly occurs at all. This group contains paravaccinal Ecthyma contagiosum, poliomyelitis, viral infection of the city of Marburg and some Arbovirus infections. Relatively few viral disorders never co-exist with lesions on the oral mucosa like e.g. Virus-hepatitis or some viral encephalitides. Groups 1 and 2, most important of all, are presented in detail regarding clinics, diagnostics, differential-diagnosis and therapy. The disorders within the other 3 groups are discussed only regarding their importance in the field of ENT-related symptoms of the oral mucosa. A number of pictures and tables completes important clinical details and give further hints to their differential-diagnosis.

Monoclonal antibodies were produced against orf virus-specified cell surface proteins in an attempt to develop reagents capable of differentiating between members of the Parapoxviridae. Two immunization protocols were used to induce an anti-orf response in BALB/c mice, one of which resulted in virus replication in the recipient. The monoclonal antibodies produced were tested for crossreactivity with bovine papular stomatitis virus (BPS) and milker's node virus (MNV) by indirect immunofluorescence assay (IFA) and immunoblotting. The results indicate that significant antigenic overlap exists between isolates of orf, MNV and BPS, even at the level of specificity provided by monoclonal antibodies. One monoclonal antibody reacted strongly in IFA with orf virus isolates, very weakly with MNV, and not at all with BPS. On immunoblots this same antibody recognized a 40-43 kDa protein in orf virus-infected cells, and also a 45-48 kDa protein in cells infected with MNV or BPS virus. The data suggest that it may be possible to define parapoxvirus strains on the basis of small variations in specific virus-directed cell surface proteins.

In a search for new fingerprinting probes for use with sheep, repeat sequences derived from five poxviruses, an iridovirus and a baculovirus were screened against DNA from sheep pedigrees. Probes constructed from portions of the parapox viruses, orf virus and papular stomatitis virus and the baculovirus from the alfalfa looper, Autographa californica, nuclear polyhedrosis virus all gave fingerprint patterns. Probes from three other poxviruses and an iridovirus did not give useful banding patterns.

Eight stomatitis papulosa (SP), four orf and two milker's nodes (MN) virus isolates were compared by restriction enzyme analysis. Considerable genetic heterogeneity was found not only between isolates belonging to the three different taxonomic groups but also between members of the same group. This heterogeneity precludes classification of parapoxviruses simply by comparison of their DNA cleavage patterns. Restriction maps were therefore prepared for 12 parapoxvirus DNAs. Fragments from defined regions of the genome were then selected and used as probes for cross-hybridizations to all other parapoxvirus DNAs. DNA fragments derived from an internal region of the genome hybridized strongly to all parapoxvirus isolates examined. In contrast, cross-hybridization of the end region of the DNA molecule was observed only between members of the same virus group. Molecular hybridization as a means of classifying parapoxvirus isolates is discussed.

Six stomatitis papulosa and three Orf virus strains were compared by serology and by DNA restriction analysis. A neutralization kinetic study revealed extensive serological cross-reactivity between all strains, but did not allow their classification. Restriction analysis of viral DNAs revealed two distinct groups among the stomatitis papulosa strains while the Orf virus strains formed a third, more heterogeneous group. The large heterogeneity of restriction patterns of parapoxvirus DNAs as compared to those orthopoxviruses is discussed.

During ultrahistological investigations of naturally occurring cases of stomatitis papulosa in cattle and Orf in sheep, nuclear changes consisting of aggregations of double membrane-containing tubular structures (outer diam. 100 to 130 nm, inner diam. 50 to 65 nm) and filamentous material were observed. These changes could be reproduced in vitro after infection of bovine (BEL) and ovine (OEL) embryonic lung cell cultures with stomatitis papulosa virus and Orf virus isolates. Nuclear tubules were mostly associated with stomatitis papulosa, whereas filaments were regularly detected in Orf virus infections in vivo. Stomatitis papulosa virus also induced nuclear tubules in vitro in the two cell culture types employed, whereas tubular structures after Orf virus infection only developed in ovine embryonic lung cell cultures in addition to filamentous structures. Orf virus infection of BEL cell cultures induced the formation of filaments. Fluorescent antibody staining revealed parapoxvirus-specific antigens only in the cytoplasm of infected cells.

Superficial epidermal surgical removal of localized bullous lesions of viral origin is recommended. An example is presented in which the patient had what we have termed "farmyard pox." This is our generic label for the clinically indistinguishable parapox viral infections acquired from farm animals, which include orf, milker's nodules, and the pox of bovine papular stomatitis. The surgery is simple and rapid, and completely removes the lesions. This eliminates the possibility of enlargement and contagion, and also promotes rapid healing.

Inasmuch as orf, milker's nodules and bovine papular stomatitis pox are clinically identical in man and are induced by currently indistinguishable parapox viruses, we propose a new generic term 'farmyard pox' for these diseases. This affords the clinician a diagnosis based on a common set of clinical and electron microscopic findings rather than one based on an uncertain or even misleading history. A case in point is reported in which the history failed to reveal a specific animal source of the virus, but electron microscopy confirmed the presence of parapox infection.
