Aqueous glutaraldehyde has been polymerized under alkaline conditions in the presence of a surfactant to yield microspheres of varied diameters. Microbeads of a nominal 300 nm diameter, made fluorescent via fluoresceinisothiocyanate, were used as a carrier of rabbit anti-human red blood cell antibodies. Specific labeling of the human red blood cells as well as diagnostic use of these fluor...

background: the aim of this study was using elisa for detection of anti- schistosoma haemato­bium antibodies in both sera and urine of patients with urinary schistosomiasis. methods: thirty three sera and urine samples were collected from patients with acute schisto­somi­asis in diyala province, east of iraq in 2006.   their diseases were confirmed by find­ing   s. haematobium ova in urine exam...

With the aim of the production of human factor VIII antigen and its corresponding antibody an epitope coding fragment of the light-chain of hFVIII, fused to a His6-tag, was isolated and over-expressed in Escherichia coli. The over-expressed hFVIII-epitope containing peptide was confirmed by its reaction with a rabbit serum directed against native hFVIII as well as antiHis6-tag antibody. An expr...

to develop an elisa technique for the detection of antibodies against babesia ovis, the infectederythrocytes were lysed and the supernatant soluble antigen, after sonication and ultracentrifugation of thelysate was used as antigen. optimal dilution of the antigen was determined by checkerboard titrations, usingpositive and negative control sera. a correlation of 85% was observed between the res...

Group A beta-hemolytic streptococcus (GABHS) is the most common bacterial cause of acute pharyngitis. Clinical criteria alone are not reliable enough to diagnose GABHS pharyngitis. Microbiological-testing is required for correct diagnosis. Although a throat swab culture remains the gold standard for documenting the presence of GABHS, a significant disadvantage of the culture is the delayed time...

BACKGROUND Methods to determine the microbial cause of community acquired pneumonia include detection of pneumococcal antigen and measurement of pneumococcal capsular antibody response. Their usefulness compared with conventional microbiological techniques was investigated in patients with pneumonia, some of whom had been treated with antibiotics. METHODS Pneumococcal capsular antigen was det...

The use of simian agent 8 (SA8) as an antigen for B virus (BV) antibody detection was evaluated in cynomolgus monkeys. Seventy-two sera judged as positive using BV antigen were all positive when the SA8 antigen was used. Out of 28 BV-negative sera 2 were positive against the SA8 antigen and one serum was classified as indeterminate. The present data indicates that detection of BV antibody can b...

The present study was carried out for the antigen detection of Feline panleukopenia virus (FPV) in diarrhoeic cats referred to the Veterinary Clinic of the School of Ahvaz University, in southwest Iran. Faecal samples were collected from 67 diarrhoeic household cats during 2005 to 2007. According to the age and clinical signs, the cats were divided into two groups; 6 months, hemorrhagic and ...

Plant diseases caused by viruses are the most menace to sustainable agriculture, leading numerous billion dollars in losses annually. Proper and accurate detection of plant is always key developing appropriate solutions manage economic them. Advances technology have simplified tools available detect diagnose at a time when control measures should be used. Currently, nucleic acid serological bas...
