Indirect Immunofluorescence Antibody (IFA) Technique was employed, for field detection of malarial parasite. The technique involved application of homologous antigen slides of Plasmodium falciparum and P. vivax prepared in the field conditions. Serological study, simultaneously using P. falciparum and P. vivax antigens, brought out a clearer picture of distribution and role of the parasite spec...

In a survey of about forty rough methemoglobin-producing colonies in sputum cultures from a series of individuals suffering from respiratory infections, twelve bile-soluble strains of suspected R pneumococci have been isolated for study. Two of these twelve strains have shown both autolysis in saline solution and serological reactions characteristic of R pneumococci. The findings offer evidence...

Surveillance systems for varicella in Europe are highly heterogeneous or completely absent. We estimated the varicella incidence based on seroprevalence data, as these data are largely available and not biased by under-reporting or underascertainment. We conducted a systematic literature search for varicella serological data in Europe prior to introduction of universal varicella immunization. A...

Syphilis, caused by the bacterium Treponema pallidum subsp. pallidum, is an infection recognized since antiquity. It was first reported at the end of the 15th century in Europe. Infections may be sexually transmitted as well as spread from an infected mother to her fetus or through blood transfusions. The laboratory diagnosis of syphilis infection is complex. Because this organism cannot be cul...

Toxoplasma gondii has frequently been named as one of the most important foodborne pathogens, in terms of its impact on human health. EFSA advised to include serological testing of pigs on T. gondii infections and audits of pig farms on risk factors for T. gondii infection (EFSA, 2011). In order to generate knowledge about the epidemiology and prevalence of T. gondii infections in pig herds we ...

The European Sero-Epidemiology Network 2 (ESEN2) aimed to compare serological results of vaccine-preventable diseases across Europe. To ensure direct inter-country comparability of hepatitis A virus antibody (anti-HAV) measurements, a standardization panel of 150 sera was developed by a designated reference laboratory and tested by participating national laboratories using assays of choice; eac...

Studies in this laboratory for the past several years have been focused on the epidemiology of hemolytic streptococcal disease in New Haven. Attention is being given to the incidence and possible clinical and epidemiological significance of the various serological types of hemolytic streptococci recovered from residents of this city. Current experience indicates that in a city of some 160,000 i...
