BACKGROUND Measles remains a major public health concern in Thailand despite the introduction of vaccination since 1984. Similar to other countries, Thailand has experienced numerous measles outbreaks including adult communities such as university student dormitories, prisons, refugee camps, and military recruit camps. These outbreaks raise questions on the seroprotective antibody level in Thai...

BACKGROUND Toxoplasma gondii, the agent of toxoplasmosis, has a complex life cycle. In humans, the parasite may be acquired either through ingestion of contaminated meat or through oocysts present in the environment. The importance of each source of contamination varies locally according to the environment characteristics and to differences concerning human eating habits and the presence of cat...

objectives Human T-lymphotropic virus (HTLV)-1 causes T-cell leukaemia and myelopathy. Together with HTLV-2, it is endemic in some African nations. Seroprevalence data from Malawi are scarce, with no reports on associated disease incidence. HTLV seroprevalence and type were tested in 418 healthy mothers from Malawi. In addition, we tested the sera of 534 children to investigate mother-to-child ...

HERPES SIMPLEX VIRUS TYPE 2 (HSV-2) seroprevalence has increased by 32% in the last decade. Overall, HSV-2 seroprevalence is 22% in the general US adult population, and in some populations, such as sexually transmitted disease (STD) clinic attendees, seroprevalence varies between 30% and 50%. Concomitant with this increase in genital herpes has been an increase in reported cases of neonatal her...

Brazil is a non-endemic country for hepatitis E virus (HEV) infection with seroprevalence from 1% to 4% in blood donors and the general population. However, data on seroprevalence of HEV in the country are still limited. This study evaluated the prevalence of past or present HEV infection in a group of blood donors representative of the general population of the city of Sao Paulo, Southeastern ...

We conducted cross-sectional and longitudinal studies to determine the distribution of and risk factors for seropositivity to Nipah virus (NiV) among Pteropus vampyrus and P. hypomelanus bats in Peninsular Malaysia. Neutralizing antibodies against NiV were detected at most locations surveyed. We observed a consistently higher NiV risk (odds ratio 3.9) and seroprevalence (32.8%) for P. vampyrus ...

The research paper deals with the comparison of seroprevalence rate of toxoplasmosis in Ukraine, India and Ghana. It determined that Ukrainian women of reproductive age contaminated with T.gondii. That fact confirmed by the 81,3 % seroprevalence rate with the predomination women living in the rural regions – 87,3±0,58 % comparatively with 71,4±1,11 % urban inhabitants. The rate of seropositive ...

The purposes of this study were to determine the seroprevalence of feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) infection among cats in Canada and to identify risk factors for seropositivity. Signalment, lifestyle factors, and test results for FeLV antigen and FIV antibody were analyzed for 11 144 cats from the 10 Canadian provinces. Seroprevalence for FIV antibody was 4...

In October 2009, two-3 months after an outbreak of a febrile disease with joint pain on the eastern coast of Madagascar, we assessed serologic markers for chikungunya virus (CHIKV), dengue virus (DENV), and Rift Valley fever virus (RVFV) in 1,244 pregnant women at 6 locations. In 2 eastern coast towns, IgG seroprevalence against CHIKV was 45% and 23%; IgM seroprevalence was 28% and 5%. IgG sero...

Seroprevalence of leptospirosis was investigated in animals using sera collected from six districts of Uttar Pradesh, India during a period of 2008-2010. Most of these animals were reported to have suffered with fever, jaundice, abortions, repeat breeding etc. A total of 500 sera collected from cattle (250), buffalo (100) and dogs (150) were subjected to microscopic agglutination test, using tw...
