Orf virus Rctimathe prototype of the genus Parapoxvirus PPVis the etiological agent of contagious ecthyma, a severe exanthematic dermatitis that afflicts domestic and wild small ruminants. The diagnosis was based on clinical examinations and molecular biology techniques. Orf virus ORFVthe prototype of the genus Parapoxvirus PPVis the etiological agent of contagious ecthyma, a severe exanthematic dermatitis that afflicts domestic and wild small ruminants [ 1 ].

The disease is usually characterized by highly infectious pustules on the lips, tongue and around the mouth. The transmission occurs by direct contact or via environmental contamination [ 23 ]. A decrease in host fitness is observed, since the lesions lead to the underfeeding of young lambs.

Contagious ecthyma is a zoonosis, and the human disease consists of conntagioso skin lesions, malaise and lymphadenopathy [ 45 ]. Immunodeficient people, however, can develop serious infections [ 6 ].

In the last several years, several ORFV outbreaks have been occurred worldwide [ 7 – 11 ].

The PPV major membrane glycoprotein B2L gene has been used in the molecular characterization and phylogenetic analysis [ 8 – 11 ]. Three sheep Ovis aries presented wartlike lesions dried-scabs on the lips, tongue and around the mouth.

The clinical diagnosis was contagious ecthyma. The outbreak area was isolated, and biological specimens were collected.

Water and scabs collected from bovine vaccinia lesions were used as negative controls. All ocinos the experimental and control samples were screened for orthopoxviruses OPV using PCR and virus growth factor -specific primers [ 17 ]. Multiple alignments of deduced amino acids sequences were generated.

Phylogenetic trees were constructed by neighbor-joining method with 1, bootstrap replicates using the Tamura 3 parameters model implemented by MEGA 3. Box indicates a MT05 singletone site, correspondent to a degenerated mutation.

Points indicate regions conserved in all viruses. Although grouped in ORFV cluster, the Brazilian samples showed variations between their sequences, and presented similarity of An increasing number of ORFV outbreaks have occurred worldwide in the last several years [ 7 – 11 ]. New molecular diagnostic tests have been developed and used in association with traditional clinical approaches [ 141819 ].

Moreover, detection of the B2L gene is the most sensitive method for virus detection because it harbors epidemiologically relevant sequence information [ 9 – 11 ]. ORFV ovijos endemic in Brazil [ 16 ].

Ectima contagioso en ovinos y caprinos by Julio Penagos López on Prezi

Although vaccination has been implemented in some regions, morbidity and economic losses are significant. An increase in the Brazilian ovine and caprine market has been observed over the last several years, leading to the emancipation of herds and the intensification of the circulation of animals. In contrast with this increase, the management of small ruminants is rudimentary, uses unsophisticated technical assistance and depends on the native vegetation. This scenario is favorable for an increased number of ORFV outbreaks.

Although the phylogenetic analysis can indicate a hypothetical conntagioso of viral strains, it is difficult to determine the precise route in which the identified ORFV strains were introduced into Brazil.

However, these data suggest that the introduction of new ORFV strains into Brazil may occur through the import of animals in order to improve herd genetics. Therefore, epidemiological surveillance can reduce ORFV outbreaks. This study provides phylogenetic information about ORFV strains, which is a matter for prospective public health dctima. EK was the leader of the project.
