Seroprevalence of toxocariasis in schoolchildren in Trinidad

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2002
The seroprevalence of toxocariasis was investigated in 1997/98 in 1009 schoolchildren (aged 5-12 years) throughout Trinidad. Infection, as measured by titre, was found to be high compared to values obtained from children in other countries. Using an excretory-secretory antigen and performing an ELISA test, it was found that 62.3% of children had an IgG

Seroprevalence of Borrelia burgdorferi in Romania

European Journal of Epidemiology, 2001
In order to assess the seroprevalence of Borrelia burgdorferi in Romania and to define associated risk factors, a cross-sectional, observational study was performed in 13 districts during 1999. Sera from healthy blood donors (1,598) and from forestry workers (1,048) were tested. A two-step testing strategy was used in which sera were tested for anti-B.

Seroprevalence of human metapneumovirus in Japan

Journal of Medical Virology, 2003
AbstractA new human pneumovirus, provisionally designated human metapneumovirus, was discovered by Dutch researchers. We examined 142 serum samples from the general population aged from 1 month to 35 years in Japan for human metapneumovirus antibody by indirect immunofluorescence assays using human metapneumovirus‐infected monkey kidney cells.

The seroprevalence of cystic hydatidosis in Oman

Annals of Tropical Medicine & Parasitology, 1999
The presence of antibodies against Echinococcus granulosus in sera from 306 humans and 390 camels in Oman was investigated by indirect haemagglutination assays. Only one of the human and five of the camel sera gave positive reactions. The reactivities of the human sera were confirmed by ELISA.

Seroprevalence of Chlamydia pneumoniae in Chile

Scandinavian Journal of Infectious Diseases, 1999
We used microimmunofluorescence to survey the prevalence of antibodies to Chlamydia pneumoniae in 403 serum samples from asymptomatic subjects aged 6 months to 89 y in Santiago, Chile. The results suggest that Chlamydia pneumoniae infection is endemic in Chile, with a seroprevalence of 60% which does not differ by gender.

Hepatitis A Seroprevalence Rate in Syria

Tropical Doctor, 2000
Hepatitis A is a benign infection, which in the developing world affects mainly children; the majority of adults are immune by the age of 30. In the last decade or so, a shift in the prevalence pattern of hepatitis A virus (HAV) infection from a low- to a high-age group has appeared in the developed countries.
