Toxoplasma gondii is a ubiquitous protozoan transmitted by felids and infection, morbidity, mortality occur in numerous marsupial species. This study explores the relationship between cat exposure burrowing bettongs (Bettongia lesueur) Arid Recovery Reserve (ARR), South Australia. We estimated seroprevalence, using modified agglutination test for T. gondii-specific immunoglobulins, cat-free cat...

Assessment of the prevalence disease or condition should consider accuracy diagnostic tests. In context new coronavirus infection (COVID-19) pandemic, laboratory testing has been one most important components overall strategy for control and prevention this infection. Seroprevalence studies have used to assess monitor level population immunity virus.

A cross-sectional serological study was conducted in Shandong province of China to determine the seroprevalence and risk factors associated with seropositivity due to pseudorabies virus (PRV) infection in small- and medium-sized farrow-to-finish herds following outbreaks of variant PRV strains. A total of 6,035 blood samples from 224 randomly selected herds were screened. The results showed tha...

The number of asylum seekers arriving in Germany has increased rapidly since 2014 and cases of vaccine-preventable diseases at reception centres were reported. Asylum seekers 12 years and older arriving in Lower Saxony were serologically screened for antibodies against measles, rubella and varicella between November 2014 and October 2015. We calculated the seroprevalence from the screening data...

Human granulocytic anaplasmosis is currently not nationally notifiable in Canada. This for the most part accounts for gross under-estimation of true incidence and prevalence of HGA and would potentially culminate in clinical missed opportunities. To the best of our knowledge, this is the first report on the seroprevalence of Anaplasma phagocytophilum in a Canadian jurisdiction with known establ...

BACKGROUND Understanding immunity, incidence and risk factors of the 2009 influenza A(H1N1) pandemic (2009 H1N1) through a national seroprevalence study is necessary for informing public health interventions and disease modelling. METHODS AND FINDINGS We collected 1687 serum samples and individual risk factor data between November-2009 to March-2010, three months after the end of the 2009 H1N...

maedi-visna (mv) virus and caprine arthritis encephalitis (cae) virus known as small ruminant lentiviruses (srlvs) cause chronic diseases in susceptible animals. the main reservoirs of these viral agents are sheep and goat. in sheep, mv virus causes a disease as the same name of the virus. this is the first seroprevalence survey of srlvs in sheep population of khorasan-e-razavi province in iran...

OBJECTIVES To examine cytomegalovirus (CMV) seroprevalence and associated risk factors for CMV seropositivity in pregnant Norwegian women. DESIGN Cross-sectional study. SETTING The Norwegian Mother and Child Cohort Study (MoBa) in addition to two random samples of pregnant women from Sør-Trøndelag County in Norway. PARTICIPANTS Study group 1 were 1000 pregnant women, randomly selected amo...

BACKGROUND The frequency of avian influenza A virus infections among poultry workers is not well understood. METHODS A seroprevalence study of market poultry workers and persons without occupational poultry exposure was conducted during 2001 in Hanoi, Vietnam. Sera were tested for avian influenza H5 and H9 antibodies by microneutralization and Western blot assays. RESULTS Seroprevalence of ...

INTRODUCTION Chagas disease is a neglected public health problem in Mexico; however, detailed studies to determine the seroprevalence in some states have not been performed. METHODS A total 1,504 human serum from thirteen communities in Estado de Mexico, were analyzed with three diagnostics techniques. RESULTS The overall seroprevalence was 9.1%, with high prevalence among people aged 51-60...
