Seroepidemiological study of infectious mononucleosis in older patients

Journal of Clinical Microbiology, 1989
In southern Tasmania, Australia, primary Epstein-Barr virus infection occurs in adults greater than 30 years of age at a higher frequency (approximately 13% of all cases) than is generally reported for other parts of the world, and approximately 7% of the general population of the region have no antibodies to the virus. Epstein-Barr virus should not be

Seroepidemiological studies on human pulmonary dirofilariasis in Spain

Annals of Tropical Medicine & Parasitology, 1990
Preliminary data are presented on a serological survey of the human population of an area with a high prevalence of Dirofilaria immitis infection in dogs. Five per cent of the sera were positive for IgG. Simultaneous radiological study revealed a pulmonary nodule in one of the positive patients, and in this case the evolution of IgG and IgM levels was ...

[Seroepidemiologic studies of human toxocariasis].

Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine, 1991
People of Southern Germany as well as European and non European asylum applicants were examined for Toxocara-infection by means of an ELISA with excretory/secretory antigen of Toxocara canis-larvae; in default of a reference method the cut off was defined statistically. In the Stuttgart area, the average seroprevalence of healthy blood donors was 4.8%;

Seroepidemiological study of Taenia saginata cysticercosis in Swaziland

Research in Veterinary Science, 1993
A cross-sectional study of Taenia saginata cysticercosis in Swaziland using a serodiagnostic ELISA for parasite antigen is described. The seroprevalence and the levels of parasite antigen were compared in the sera of cattle from different geographical localities, and from areas of high or low population density.

Seroepidemiological Studies on Nasopharyngeal Carcinoma in China

1985
Publisher Summary This chapter explores simple and sensitive techniques that can be conveniently applied in the high-nasopharyngeal carcinoma (NPC) risk field for the early detection of NPC. It is noted that early treatment gives a good prognosis and helps to explore the roles of Epstein–Barr (EB) virus, environmental factors, and genetic factors in ...

[Viral hepatitis B. Seroepidemiological study in Veneto].

Bollettino dell'Istituto sieroterapico milanese, 1982
Sera from 3160 subjects without overt liver disease were tested for the presence of HBsAg, anti-HBs, anti-HBc. This group corresponds to a 4%, sample of the population resident in Padova and the surrounding district, selected according to sex and age distribution (in 5 to 5 year classes). The overall prevalence of HBV infection was 23%.
