Investigations on the risk of virus infection in dental surgery. Preliminary data.

Four virus strains -- influenza A/Texas 1/77 (H3N2) an A/USSR 90/77 (H1N1), adenovirus and parainfluenza type 2 -- were isolated from different specimens collected in dental surgery rooms. High levels of antibodies to respiratory viruses (influenza, parainfluenza 1, 2 and 3), adeno-, cytomegalic and herpes viruses, as well as the presence of HBsAg and anti-HBs could be detected in sera from patients hospitalized for dento-maxillofacial surgery. An epidemiological survey among dentists and dental assistants confirmed their exposure to an enhanced risk of occupational virus contamination, as compared with other categories of medical personnel.

Prevalence of antiviral antibodies in workers handling wastewater and sludge.

Serological investigations were performed between 1977-1978 with 972 serum samples from 243 subjects having either direct (group A) or sporadic (group B) occupational contact with wastewater or sludge. the control group (C) was represented by 100 persons having no contact with such material. The sera were tested against influenza, parainfluenza, adeno-, herpes, coronavirus, rickettsial and chlamydial antigens, as well as for the presence of HBsAg and anti-HBs. Statistically significant differences between group A and groups B and C were found as regards the prevalence of antibodies to adenovirus and parainfluenza virus type 1 antigens.

Studies regarding a fibrosarcoma induced in Sprague-Dawley rats by a murine cytomegalovirus. Note I. Aspects related to the character and reproduction of the tumor.

Through passages on Sprague-Dawley rats (performed during seven years) the serial transmissibility of a fibrosarcoma type tumor, with a tendency to local recurrence and locoregional metastasis formation, is demonstrated. The tumor was initially obtained by in vitro transformation of primary total rat embryonic cultures under the influence of a murine cytomegalovirus (M-CMV). In the course of passages, susceptible (S) and resistant (R) animal lines to the respective tumor could be obtained. The R and S crossings demonstrated the dominant transmission of S.
