BACKGROUND & OBJECTIVES Dengue fever (DF) is associated with significant morbidity and mortality in the tropical and sub-tropical regions of the world. Since there are no effective antiviral drugs for treatment, clinicians often rely on the accurate diagnosis of dengue fever to begin supportive therapy at early stages of the illness. The objective of this study was to develop an in-house dengue...

The serological reactivity in indirect ELISA of five different bluetongue virus (BTV) serotypes (4, 10, 15, 16 & 20) was compared using polyclonal antisera raised against virus particles and an outer structural protein, VP2. Rabbit and sheep antisera against BTV-10 produced higher ELISA values with their homologous antigens than with heterologous serotypes. A hyperimmune rabbit serum specific f...

for the evaluation of autoantibodies in pemphigus vulgaris (pv), an indirect elisa assay was developed by using a semi-purified human epidermal skin extracted with approximately a molecular weight (m.w.) of 130-160 kda. the evaluation of pemphigus igg, igm and iga autoantibodies in 75 patients and 50 control sera indicated that this indirect elisa assay was a useful method for the detection of ...

conclusions: it was concluded that the elisa is a suitable method for large scale screening of antibodies against aspergilloma. the easy techniques have shortened the required time of tests (approximately 1.30 hours for our elisa, as opposed to 2.30 hours with commercial elisa kit). this may be a substantial benefit for large numbers of samples that should be tested. materials and methods: an i...

An ultra-sensitive sandwich ELISA was developed for detection of AFM1 in milk. The assay involved the immobilization of rat monoclonal antibody of AFM1 in 384 microtiter plate to capture AFM1 antigen. This was detected by tracer secondary rabbit poly-clonal antibody labelled with horseradish peroxidase upon addition of a luminol-based substrate. Milk samples with different fat percentage were a...

Poultry industry has high annual growth rate in Pakistan. Mycoplasmosis, separately or in combination with other diseases, cause major setbacks to poultry industry. Due to significant role of Mycoplasmosis in poultry industry, its control programme success depends on timely and accurate diagnosis of infected flocks. Poultry flocks are generally screened for Mycoplasma by Rapid Slide Agglutinati...

An enzyme-linked immunosorbent assay (ELISA) using commercially available reagents was compared with standard serological tests for determination of antibody titers in patients with acute measles. The measles-specific ELISA was as sensitive as complement fixation, hemagglutination inhibition, and indirect fluorescent-antibody methods. The ELISA method used was simple, sensitive, inexpensive, an...

the objective of this study was to compare an indirect elisa, based on a purified 60 kda envelope glycoprotein (gp51su), with a pourquire indirect elisa for the detection of antibodies to the bovine leukemia virus. for conducting this research, 340 serum samples were collected from two different breeds of cows (sarabi and holestin) in different herds. commercial elisa revealed positive results ...
