[The use of hemagglutination inhibition tests and complement fixation tests for evaluation of immunity states and diagnosis of recent rubella infections].

Comparative HAI and CF study of German measles antibodies in 575 sera collected from subjects of different age gave positive HAI reactions in 87% of the cases and positive CF reactions in 55% of the cases. The greater sensitivity of HAI and the longer presence of these antibodies justifies the use of this test for investigating the state of immunity in German measles. The combined use of the two tests for the diagnosis of the disease is very useful especially when the first serum sample is collected some time after the onset when the increase in serum antibody titers can only be demonstrated by CF, as HAI antibodies reach a high titer soon after the onset.

[Improvement of rapid laboratory methods for the diagnosis of streptococcal infections].

In 1975, clinical and epidemiological investigations were carried out on streptococcal infections, affecting 261 persons in a children's community. Rapid laboratory tests were used, employing commercial sodium amyl polyethylen microtablets. Of the total persons investigated 24.5% (64) presented primary streptococcal infections and 0.3% (1) complications. Environmental complications was 5% greater in the communities with scarlet fever foci than in the intact communities. The absence of late manifestations in the 1--4 year-old children attests to the effectiveness of the preventive measures taken.

Importance of associated viral and bacterial infections in the production of acute pneumonias.

Bacteriologic and virologic investigations carried out in a group of 85 patients with acute pneumonia have allowed the determination of the etiologic agent in 52.9% of the cases. Of these, 40% showed combined viral and bacterial infections. Mixovirus infections were frequently associated with staphylococcic ones (7 out of 8 cases) and adenovirus infections with the pneumococcic ones (6 out of 7 cases). The most severe and longdrawn clinical pictures with frequent pleuropulmonary complications (in 22.24% of the cases) had a biphasic evolution in only 6 of the 18 pneumonias of mixed etiology. For their high frequency and their clinical peculiarities, mixed etiology pneumonias might be considered as distinct clinical entities.

[Clinical syndrome of convulsive cough of adenoviral etiology in a children's collective].

Bacteriological, viral and serological investigators were carried out in a community with 100 prescholar children (Kindergarden), 34 of whom presented a clinical syndrome of whooping cough, in order to establish the bacteriologic or viral etiology of the syndrome. The etiologic role of organisms of the Bordetella, B. pertussis and B. parapertussis was invalidated by the bacteriologic and serological tests. Viral and serological tests, performed to demonstrate the participation of viral agents in the causation of this clinical syndrome, established an adenoviral diagnosis in 13 (43.3%) of the 30 children. Adenovirus type 6 was isolated and there was a significant increase in the titers of antibodies to adenoviruses.

[Some respiratory viruses in the etiology of acute upper respiratory infections].

The viral etiology of acute respiratory diseases, determined in 107 children admitted to hospital during the 1966-1969 period, was confirmed in 36% of the cases by isolation of the viral agent and in 59% by serologic reactions. Parainfluenza viruses, especially of type 1 and 3, were encountered more often in the etiology of acute or obstructive laryngitis, and the syncytial respiratory virus in tracheobronchitis.

The role of some viruses in acute pneumonias in adults.

Virological and bacteriological investigations were performed in 85 patients with acute pneumonias and virus isolation or serological evidence of virus infection were obtained in 37.6% of the cases. Influenza A2 and B viruses were incriminated in 14.1% of the patients; parainfluenza viruses in 7% and adenoviruses in 17.2% of the cases. Coxsackie virus was isolated from one patient's blood, and poliovirus 3 was recovered in 3 cases. In 5 cases associated virus infections were detected.

Epidemiological aspects of the evolution of influenza infections in a large urban centre (B.) in Romania in 1988.

The study describes the peculiarities of the influenza infection evolution, in 1988, in a large urban centre, B., in Romania, as they result from the active surveillance of the epidemiological process of influenza and other viral respiratory tract infections, by means of a complex methodology based on clinical-epidemiological and laboratory techniques. The low endemic morbidity, the evolution of these seasonally ascendant specific incidence, the endemic aspect of influenza infection being maintained as a consequence of its predominance in infants and children, the clinically mild form of the outbreaks, all these are specific elements of the epidemiologic impact in the surveyed territory. They are discussed in accordance with the results of laboratory tests (seroepidemiologic and diagnostic) that confirmed the permanent circulation of influenza virus types A(H1N1), A(H3N2) and B in all age groups.

Epidemiological features of influenza in a large town of Romania during 1983.

Data supplied by the active influenza surveillance - including clinical, epidemiological and laboratory investigations - allowed the characterization of the particularities of an influenza outbreak caused by A(H3N2) virus in a large town of Romania in March 1983. The epidemiological impact of influenza in 1983 is discussed in the light of the complex relationships between the antigenic structure of circulating influenza strains and the profile of antiinfluenza immunity of the population.

Epidemiologic features of influenza in a large urban centre (B.) in Romania, in 1987.

The study presents the peculiarities of influenza evolution in 1987 in a large town in Romania. These features were defined by a complex methodology, based on clinical, epidemiologic and laboratory investigations, used in the active control of the epidemiologic process kinetics. The influenza viruses type A (H1N1 and H3N2) had a major role in the infecting and immunizing contacts in all age groups whereas the influenza virus type B had a reduced circulation. The epidemiologic influenza impact in 1987 is discussed from the point of view of the complex relationships between the antigenic structure of circulating influenza viruses and the anti-influenza immune profile of the population under the influence of extremely complex economic, social and natural factors.
