Seroepidemiological Studies of Transfusion-Associated Hepatitis
Journal of Infectious Diseases, 1971patients with transfusion-associated and other hepatitis [1-3], and the Herpes group of viruses, specifically cytomegalovirus (CMV) [4-7] and, to a lesser extent, Epstein-Barr virus (EBV) [8]. The association between hepatitis and HAA is strong; this antigen has been found in the serum of up to 80 96 of patients with transfusion-associated hepatitis ...

Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. 1. Abt. Originale. A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie, 1981324 sera from unselected male and 581 sera from female patients as well as 268 sera from prostitutes were studied for antibodies against Campylobacter fetus using the complement fixation test. Antigen was Campylobacter fetus subspecies intestinalis. 3.9% of the sera showed low but relevant antibody titers.

Comments on Seroepidemiologic Studies
2015If the tools for the control of transmission are not available, the application of seroepidemiologic methods, as an exercise in the tropics, just in order to assess the magnitude of the problem of malaria transmission, should be restricted. Application of seroepidemiologic methods in connection with control operations seems valuable.

Herpesvirus infection and cervical anaplasia—a seroepidemiological study
International Journal of Cancer, 1977AbstractIn a cohort of 23,146 pregnant females followed for 37–56 months subsequent to collection of prenatal sera, 57 cases of carcinoma of the cervix were encountered. Three controls were selected for each case from the residual cohort matched to cases for age, residence, number of prior cytology smears taken, and the date of entry to the study.

Seroepidemiological study of rotavirus infection in rural Ghana
Annals of Tropical Paediatrics, 1984Children in a village in rural Ghana were found to have acquired antibody to rotavirus by the age of two years. The results of our study suggest that primary infection takes place early in infancy. Fifty-six per cent of the three to 20-months-old had a four-fold rise in antibody levels during the six months follow-up period and 72.2% of them had one or

Seroepidemiological study of Taenia saginata cysticercosis in Swaziland
Research in Veterinary Science, 1993A 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
1985Publisher 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 ...

A Seroepidemiological Study of Amebiasis in Adults in Maracaibo, Venezuela
The American Journal of Tropical Medicine and Hygiene, 1981Eight hundred and forty-eight sera collected from adult patients attending the Central and University Hospitals and from blood donors at the Blood Bank in Maracaibo, Venezuela, were screened for serologic evidence of Entamoeba histolytica infection, employing the indirect hemagglutination test. The seropositivity rates obtained ranged from 4.4-6.5% and
