Using the MAP1-B enzyme-linked immunosorbent assay, we tested 1,318 serum samples collected from sheep and goats at 28 sites in the five divisions of The Gambia to determine the Ehrlichia ruminantium seroprevalence rates and to assess the risk for heartwater. About half (51.6%) of 639 sheep were positive, with seroprevalence rates per site varying between 6.9% and 100%. The highest seroprevalen...

A serological survey to detect Schmallenberg virus (SBV)-specific antibodies by ELISA was organized in the Belgian sheep population to study the seroprevalence at the end of the epidemic. One thousand eighty-two sheep samples which were collected from 83 herds all over Belgium between November 2011 and April 2012 were tested. The overall within-herd seroprevalence and the intraclass correlation...

Background: The prevalence of Helicobacter pylori (H. pylori) infection is reported to be more than 50% worldwide. It has been associated with peptic ulcer disease, gastric carcinoma, and mucosal-associated lymphoid tissue lymphoma. The seroprevalence of H. pylori varies greatly among societies and geographical locations. The objective of this study was to determine the seroprevalence and facto...

Bluetongue virus (BTV) caused infection is commonly determined in ruminants including sheep and cattle. However, there is a little information about the seroprevalence of BTV in yaks. The aim of this study was to describe the seroprevalence rate BTV in unvaccinated yaks in Issyk Kul, Kyrgyzstan. A total of 168 serum samples were collected from yaks between September to November 2012. Antibodies...

Severe fever with thrombocytopenia syndrome virus (SFTSV) has been prevalent for some time in China and it was first identified in 2010. However, the seroprevalence of SFTSV in the general population in southeastern China and risk factors associated with the infection are currently unclear. Blood samples were collected from seven counties across Zhejiang province and tested for the presence of ...

Blood transfusion is an important mode of transmission of infections to recipients. The aim of the study was to assess the prevalence of transfusion-transmissible infections among blood donors. For this, a 3.5-year retrospective study, from October 2002 to April 2006 was conducted at the blood transfusion centre of Maharaja Agrasen Medical College, Agroha (Hisar) Haryana. Donors were screened f...

Data on prevalence of hepatitis E virus (HEV) in Malawi is limited. We tested blood samples from HIV-uninfected and -infected populations of women and men enrolled in research studies in Malawi during 1989-2008 to determine the seroprevalence of HEV, hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Samples were tested for IgG against HEV, total antibodies against H...

OBJECTIVE To examine the type specific seroprevalence of herpes simplex virus (HSV) types 1 and 2 infections, stratified by age and gender, and associated risk factors for HSV-2 seropositivity in Poland. METHODS 2257 serum samples of individuals from 15-65 years were randomly selected from serum banks in four different geographical regions of Poland, including the Zachodnio-pomorskie, Warmińs...

Peste des petits ruminants, caused by the peste des petits ruminants virus (PPRV), is a highly contagious and economically important transboundary viral disease of domestic and wild small ruminants and a major hindrance to small-ruminant production in Nigeria. The seroprevalence and distribution of PPRV antibodies in small ruminants in rural households, farms, live animal markets and slaughter ...

BACKGROUND Cats are essential in the life cycle of Toxoplasma gondii as they can shed the environmentally resistant oocysts after acquiring infection. Human populations living in cities with high densities of feral cats are therefore likely to be at risk of infection. The current study is the first to estimate the seroprevalence of T. gondii in the feral cat population in Qatar. We investigated...
