    Bovine cystocercosis is a parasitic disease that afflicts the muscles of cattle and is caused by larvae of the human tapewormTaenia Saginata. If people consume beef containing these parasites they can acquire intestinal tapeworm infections.

    Bovine cystercosis, also known as bladder worm or beef tape worm, is a parasitc zoonosis due to the cestode Taenia saginata. It causes few symptoms in the animal but it is an important zoonosis.


    OIE, List B disease

    Susceptible species

    The beef is a intermediate host and man is the final host.


    Bovine cysticervosis is worldwilde distributed. In the Pacific it is only reported in Australia and New Zealand.

    Clinical signs 

    In animals there is usually no clinical sign associated. However heavy infections may cause myocarditis andheart failure associated with developing cysts in the heart.

    Post-mortem findings 

    Lesions consist of cysticerci in cysts, they are 5-8 mm by 3-5 mm, translucid and filled with a brownish to pinkish liquid, sometimes the 'head' of the metacestodes can be see as a white spot. Cysts are essentially found in the following muscles:

      •    - Heart,
    •    - Tongue,
    •    - Masseters and Diaphragm,
    •    - Shoulder muscles
    •    - Intercostal muscles,
    •    - Oesaphage

    More rarely cysts are found in the liver, the lungs and the brain.

    Differential diagnosis 

    Lesions must be differentiated from sarcosporidiosis and toxoplasmosis.

    Specimens required for diagnosis 

    The diagnosis is usually made during meat inspection. However serologic test has been developed.


    Beef usually get infected by grazing on pasture contaminated by human feces (which can come from sewage water or direct pollution). Occasionally in-utero contamination occurs.

    Human get infected by eating unproperly cooked meat (<60°C)

    Risk of introduction   

    Introduction could occur through importation of infected cattle, meat or material contaminated by human feces. Humans can also introduce it into the country.

    Control / vaccines 

    Control is done through public hygien and proper meat inspection at slaughterhouse.

    Cysts can be destroyed by freezing  at -18°C for 5 days or at -10°C for 10 days or by cooking at 56°C for 5 minutes.

    CA 15-3 ELISA Kit

    ca15-3-elisa-kitINTENDED USE
    The CA15-3 for the quantitative determination of the Cancer Antigen CA15-3 concentration in human serum. This kit is intended for research use only.

    Breast cancer is the most common life-threatening malignant lesion in women of many developed countries today, with approximately 180,000 new cases diagnosed every year. Roughly half of these newly diagnosed patients are node-negative, however 30% of these cases progress to metastatic disease.
    There are a number of tumor markers that can help clinicians to identify and diagnose which breast cancer patients will have aggressive disease and which will have an indolent course. These markers include estrogen and progesterone receptors, DNA ploidy and percent-S phase profile, epidermal growth factor receptor, HER-2/neu oncogene, p53 tumor suppressor gene, cathepsin D, proliferation markers and CA15-3. CA15-3 is most useful for monitoring patients post-operatively for recurrence, particularly metastatic
    diseases. 96% of patients with local and systemic recurrence have elevated CA15-3, which can be used to predict recurrence earlier than radiological and clinical criteria. A 25% increase in the serum CA15-3 is associated with progression of carcinoma. A 50% decrease in serum CA15-3 is associated with response to treatment. CA15-3 is more sensitive than CEA in early detection of breast cancer recurrence. In combination with CA125, CA15-3 has been shown to be useful in early detection of relapse of ovarian
    cancer. CA15-3 levels are also increased in colon, lung and hepatic tumors.

    The CA15-3 ELISA test is based on the principle of a solid phase enzyme-linked immunosorbent assay. The assay system utilizes a monoclonal antibody directed against a distinct antigenic determinant on the intact CA15-3 molecule is used for solid phase immobilization (on the microtiter wells). A rabbit anti-CA15-3 antibody conjugated to horseradish peroxidase (HRPO) is in the antibody-enzyme conjugate solution. The test sample is allowed to react sequentially with the two antibodies, resulting in the CA15-3 molecules being sandwiched between the solid phase and enzyme-linked antibodies. After two separate 1-hour incubation steps at 37C, the wells are washed with water to remove unbound labeled antibodies. A solution of TMB Reagent is added and incubated for 20 minutes, resulting in the development of a blue color. The color development is stopped with the addition of Stop Solution changing the color to yellow. The concentration of CA15-3 is directly proportional to the color intensity of the test sample. Absorbance is measured spectrophotometrically at 450 nm.

    25OH Vitamin D Total, ELISA, 96 tests

    The Gentaur 25OH Vitamin D Total ELISA is a solid phase Enzyme Linked Immunosorbent Assay performed on microtiterplates. During a first 2 hours incubation step, at room temperature, total 25OH Vitamin D (D2 and D3) present in calibrators, controls and samples is dissociated from binding serum proteins to fix on binding sites of a specific monoclonal antibody. After 1 washing step, a fixed amount of 25OH Vitamin D-labelled with biotin in presence of horseradish peroxidise (HRP), compete with unlabelled 25OH Vitamin D2 and 25OH Vitamin D3 present on the binding sites of the specific monoclonal antibody. After a 30 minutes incubation at room temperature, the microtiterplate is washed to stop the competition reaction. The Chromogenic solution (TMB) is added and incubated for 15 minutes. The reaction is stopped with the addition of Stop Solution and the microtiterplate is then read at the appropriate wavelength. The amount of substrate turnover is determined colourimetrically by measuring the absorbance, which is inversely proportional to the total 25OH Vitamin D (D2 and D3) concentration. A calibration curve is plotted and the total 25OH Vitamin D (D2 and D3) concentrations of the samples are determined by dose interpolation from the calibration curve.

    Rat IgG ELISA

    Immunology KitsINTENDED USE

    The IMMUNO-TEK Rat IgG ELISA* Kit is a rapid, easy to use enzyme linked immunosorbent assay (ELISA) designed for the measurement of rat IgG in rat serum, plasma, saliva, mucosa, cell culture fluid from rat cells or other biological sample. The assay contains ready-to-use reagents and takes less than two hours to perform. The microplate and detector antibody in the kit react with all subclasses of rat IgG.

    * Research Purposes Only.  Not For in vitro Diagnostic Use.


    Microplate wells coated with polyclonal antibodies to rat IgG form the capture phase of the assay. Rat IgG specimen samples along with the supplied standard are diluted appropriately with Assay Diluent and are then incubated in the microplate wells. After a wash step, captured rat IgG in the well is incubated with detector antibody, a polyclonal anti-rat IgG conjugated to horseradish peroxidase (HRP). This antibody reacts only to the Fc portion of the immunoglobulin molecule allowing for the specific detection of IgG. After another wash step, the chromogenic substrate tetramethyl benzidine (TMB) is added and a blue color develops in proportion to the amount of rat IgG that has been bound to the antibody-coated plate. The enzyme reaction is stopped by the addition of Stop Solution which results in a color change to yellow which can be measured spectrophotometrically at 450 nm. The concentrations of rat IgG are then calculated from a standard curve.

    Parasitology: Cysticercosis Antigen ELISA

    Apdia beeld hersenscanThe Cysticercosis Antigen (Ag) ELISA (Ref. 650501) is a sandwich Enzyme-Linked ImmunoSorbent Assay based on monoclonal antibodies for the qualitative determination of viable metacestodes (cysticerci) of Taenia spp. in human and porcine serum samples.

    -  Analytical sensitivity: 1 cyst is detectable in certain conditions
    - Incubation times: assay 45 minutes + sample prep <30 minutes
    - Available format: 96T

    Taenia solium cysticercosis is an infection of humans and pigs with metacestode larvae (cysticercus) of Taenia solium. Circulating antigen detection in serum is an important diagnostic method that indicates the presence of viable parasites. The monoclonal antibodies used in this assay are produced against excretory secretory products (ESP) of viable T. saginata cysticerci. The glycoprotein antigens detected by these monoclonal antibodies are present on the tegument and in the excretory secretory products of metacestodes.

    The assay demonstrates the presence of viable cysticerci only, it does not detect degenerated or calcified cysticerci. In this respect, unlike antibody detection, measurement of circulating antigen levels allows differentiation of cysticercosis cases with viable parasites, with antigen levels correlating to the numbers and size of lesions. It can as such also provide a tool for serological monitoring of antiparasitic therapy in human or pigs: antigen levels drop rapidly after successful anthelminthic treatment.

    Porcine cysticercosis

    The assay is genus specific, not species specific. The assay does not allow the differentiation between infections of different Taenia species in pigs. In experimentally infected pigs, circulating antigens were first detected between 2 and 6 weeks post infection and remained present generally throughout an observation period of 6 months, even in pigs carrying only five to eight living cysts. The minimum number of living cysts, that could be detected using the Cysticercosis Ag ELISA, was one.

    Human cysticercosis

    Because T. solium is the only Taenia sp. causing cysticercosis in man, the test is specific. No cross-reactions were observed with sera from patients with other parasitologically and/or serologically confirmed infections. The sensitivity of the assay decreases when the number of viable cysts is low; infections with one viable cyst are often not detectable. Antigen levels are generally higher in extraparenchymal neurocysticercosis (NCC) (particularly subarachnoid NCC) than in intraparenchymal NCC; therefore, high antigen levels should lead one to suspect the presence of extraparenchymal NCC.
