Determination of professional activities, which are connected with higher risk toxocariasis, is very important for well-timed diagnosis and prevention. That why our research aimed to investigate the spread toxocariasis in people, whose activities related forests. Thirty-three people included study – eight employees Forest Research Institute at Bulgarian Academy Sciences, Sofia, 25 forestry work...

Using indirect haemagglutination assay, combined with a collection of blood samples on blotting cards, seroepidemiological surveys of cytomegalovirus infections during early infancy have been done in different populations (French and immigrant) in urban areas. The comparison of CMV antibody status of mothers and their children at 10 months and at 2 years of age enables possible factors of viral...

Seroepidemiological studies showed that the human polyomavirus KI (KIPyV) is common in the human population, with age-specific seroprevalence ranging from 40-90 %. Genome epidemiological analyses demonstrated that KIPyV DNA is predominantly found in respiratory tract samples of immunocompromised individuals and children suffering from respiratory diseases, but viral sequences have also been det...

Prolonged cough occurs in a large proportion of the 2 million pilgrims who participate in the annual Hajj in Saudi Arabia. In a prospective seroepidemiological study to determine the incidence of pertussis among 358 adult pilgrims, 5 (1.4%) were found to have acquired pertussis (defined as prolonged cough and a >4-fold increase in the level of immunoglobulin G to whole-cell pertussis antigen). ...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease in East Asia. It is thought that the SFTS virus (SFTSV) circulates between ticks and animals in nature and that the virus is transmitted to humans by tick bites. SFTS is endemic to Nagasaki in western Japan; however, epidemiological information regarding SFTSV in Nagasaki is not known. In this study, we performed SFTSV Ig...

The serum vibriocidal antibody is the only recognized predictor of protection from cholera, but no seroepidemiological data have been gathered since the emergence of Vibrio cholerae O139. We assessed the association between the vibriocidal antibody titer and protection from cholera in an endemic setting. Although a higher baseline vibriocidal titer correlated with protection from V. cholerae O1...

In this paper, we emphasize the uses of serum banks in cancer research. These include not only case/control studies but also prospective seroepidemiological studies in which the development of a serological marker, such as a viral antibody or viral antigen, can be correlated with the subsequent development of cancer in either an active surveillance program or the use of cancer registries or hos...
