We developed a new recombinant enzyme-linked immunosorbent assay (rELISA) for serodiagnosis of contagious agalactia (CA), a disease caused by Mycoplasma agalactiae in sheep and goats. The assay is based on two M. agalactiae surface proteins, namely, P80 and P55. Identification of these immunodominant and common antigens was accomplished by examining the antibody response elicited in sheep durin...

AIMS--To compare the sensitivity, specificity, and practicality of recombinant proteins in serological tests for the detection of human parvovirus B19 IgG and IgM. METHODS--Indirect enzyme linked immunosorbent assays using B19 structural proteins expressed in Escherichia coli were developed for the detection of B19 specific IgG and IgM (rELISA-G and rELISA-M). Cells infected with baculovirus ex...

The region(s) of hsp70 critical for sulfogalactolipid (SGL) recognition has been defined through deletion analysis and site-directed mutagenesis. Truncated polymerase chain reaction products of hsp70 generated N-terminal fragments of 43, 35, 29, and 22 kDa. The C terminus substrate-binding domain (28 kDa) was also expressed. The N-terminal ATPase domain (rP43) shared the binding specificity of ...

Immunological diagnostic methods for Trypanosoma cruzi depend specifically on the presence of antibodies and parasitological methods lack sensitivity during the chronic and "indeterminate" stages of the disease. This study performed a serological survey of 1,033 subjects from 52 rural communities in 12 of the 18 municipalities in the state of Querétaro, Mexico. We detected anti-T. cruzi antibod...

Antiphospholipid antibodies, including anticardiolipin antibodies, are frequently detected in sera from patients with systemic lupus erythematosus (1). Numerous reports have associated these autoantibodies with various venous and arterial thrombotic disorders, including cerebral infarction (2), deep venous thrombosis (3), thrombocytopenia (1), pulmonary embolism (4), and recurrent fetal loss wi...

leptospirosis in cattle is a worldwide problem associated with abortion, agalactia, still birth and infertility resulting in major economic losses to dairy industry. there is lack of data regarding seroprevalence of bovine leptospirosis in eastern india. so, with the aim to investigate the prevalence of the disease in odisha and west bengal state of eastern india, a total of 350 cattle serum sa...

An outbreak of Neospora caninum-associated abortion occurred in a South Carolina dairy wherein greater than 10% of the herd aborted over a 4-month period. Of the total number of cows at mid-late gestation, nearly 40% (28/71) aborted while the remaining 60% (43/71) gave birth to normal calves. Immunohistochemical examination of brain tissue from a subset of aborted fetuses confirmed N. caninum a...

BACKGROUND Although several studies have demonstrated an association between infection with Chlamydia pneumoniae and asthma, these were mainly limited to exacerbation of symptoms in adults with known asthma OBJECTIVE We investigated the role of C. pneumoniae infection in 149 atopic children with chronic cough and asthma, comparing them with 241 control non-atopic subjects presenting at Olomou...

Leptospirosis in cattle is a worldwide problem associated with abortion, agalactia, still birth and infertility resulting in major economic losses to dairy industry. There is lack of data regarding seroprevalence of bovine leptospirosis in eastern India. So, with the aim to investigate the prevalence of the disease in Odisha and West Bengal state of eastern India, a total of 350 cattle serum sa...

There was followed the development of serological findings in patients with proved positivity only in classes IgA and/or IgM of chlamydial antibodies (without IgG), which can be suspected of showing "false" positivity. 184 patients were repeatedly examined for chlamydial antibodies in their sera (interval between collections up to three months) using a genus specific rELISA. Sera were also test...
