The conclusions to be drawn from this study are that while there appears to be evidence of serological distinctions between B. abortus and B. melitensis cultures as studied by earlier workers, the experiments reported in this paper show no serological distinctions among the six strains used in the study. B. melitensis II and B. melitensis III were found to be identical with the bovine and swine...

The objective of this study is to determine if a Chagas disease protocol starting with a serological survey is as reliable at identifying insect-infested areas as one using the gold standard entomological survey. The study found that health center areas infested with Rhodnius prolixus were identified using a threshold seroprevalence of 0.1%. The serological survey took half the time and was 30%...

A COMPARATIVE STUDY OF AN ELISA TEST AND AN INDIRECT IMMUNOFLUORESCENCE TEST FOR SEROLOGICAL DIAGNOSIS OF BABESIA BOVIS INFECTION. Detection of antibodies to Babesia bovis in cattle is essential for the understanding of the epidemiology of babesiosis and this study was concerned with comparing the indirect fluorescent antibody with the ELISA. Both assays gave rise to 100% sensitivity whilst the...

INTRODUCTION AND OBJECTIVE Recently, investigations in a swine herd identified evidence of the existence of a novel member of the Hepadnavirus family endemic in swine. The aim of this study was to investigate the serological and molecular markers of Hepadnavirus circulation in Brazilian domestic swine and wild boar herds, and to evaluate the identity with HBV and other Hepadnaviruses reported p...

The spread of infectious diseases and vaccination history are common subjects of epidemiological and immunological research studies. Multiplexed serological assays are useful tools for assessing both current and previous infections as well as vaccination efficacy. We developed a serological multi-pathogen assay for hepatitis A, B and C virus, cytomegalovirus (CMV), Toxoplasma gondii, and Helico...

This cross-sectional study of 420 women in two public maternity hospitals from August 2004 to May 2005 evaluated the application of a prenatal toxoplasmosis serological screening protocol in Belo Horizonte, Minas Gerais State, Brazil, and the information provided to susceptible pregnant women. Ninety-eight percent of women received prenatal care and 97% underwent the initial serological screeni...

BACKGROUND There was a recent epidemic of chikungunya (CKG) in Calicut and other northern districts of Kerala, South India, affecting thousands of people. AIMS To study the cutaneous manifestations of CKG and to have a serological and histopathological correlation. METHODS A total of 162 patients (63 males and 99 females) with cutaneous manifestations of CKG were enrolled in the study and s...

Effective control of animal tuberculosis is possible only with a comprehensive examination the biology pathogen, epizootiology, pathogenesis, prevention methods, economic and environmental factors that affect course disease. It known radiation exposure leads to autosensitisation body by breakdown products its tissues development non-specific (false) immunological reactions. Therefore, purpose s...
